The Red List of

Magnoliaceae

BOTANIC GARDENS CONSERVATION INTERNATIONAL (BGCI)is a membership organization linking botanic gardens in over 100

countries in a shared commitment to biodiversity conservation,

sustainable use and environmental education. BGCI aims to mobilize

botanic gardens and work with partners to secure plant diversity for the

well-being of people and the planet. BGCI provides the Secretariat for

the IUCN/SSC Global Tree Specialist Group.

FAUNA & FLORA INTERNATIONAL (FFI), founded in 1903 and the

world’s oldest international conservation organization, acts to conserve

threatened species and ecosystems worldwide, choosing solutions that

are sustainable, are based on sound science and take account of

human needs.

THE GLOBAL TREES CAMPAIGN (GTC) is undertaken through a

partnership between BGCI and FFI. GTC’s mission is to prevent all tree

species extinctions in the wild, ensuring their benefits for people, wildlife

and the wider environment. GTC does this through provision of

information, delivery of conservation action and support of sustainable

use, working with partner organisations around the world.

THE IUCN/SSC GLOBAL TREE SPECIALIST GROUP (GTSG)forms part of the Species Survival Commission’s network of over 7,000

volunteers working to stop the loss of plants, animals and their habitats.

SSC is the largest of the six Commissions of IUCN – The International

Union for Conservation of Nature. It serves as the main source of advice

to the Union and its members on the technical aspects of species

conservation. The aims of the IUCN/SSC Global Tree Specialist Group

are to promote and implement global red listing for trees and to act in

an advisory capacity to the Global Trees Campaign.

Magnolias indeed are a plant‘passion’ of mine and I havebeen extoling their virtues ever

since seeing the magnificent Asiatic treemagnolias in the Valley Gardens atWindsor in the late 1960’s. Being askedto write this Foreword for the Red List isboth an honour and a pleasure as this willhighlight how much is known about thefamily, its taxonomy, distribution andthreats thus building on the informationfound in the first Red List printed in 2007.But it also highlights the world-widewealth of knowledge and expertise thereis out there in organisations, societiesand private collectors who are passionateabout this plant family.

This updated Red List highlights a numberof important facts. 48% of all Magnoliaspecies are threatened in the wild, withhabitat loss due to logging and agriculture

being identified as the main threats. chinaand Latin America (neotropics) are thetwo botanical ‘hotspots’ with manyorganisations involved with specificconservation projects.

This was demonstrated when the ‘WorldMagnolia center’ was established in theSouth china Botanical Garden (ScBG) in partnership with Botanic Gardensconservation International (BGcI) and theMagnolia Society International (MSI) in2009. Such partnerships are key given theimportance of both in and ex situconservation work that is currently beingundertaken around the world. TheMagnolia Society International also plays akey role with conservation initiativesinvolving threatened species primarilyfrom the neotropics. This is importantparticularly as c.100 species have beendiscovered over the past 15 years. An example of this is funding of the conservation, Propagation andRestoration of costa Rican species. In addition, the First InternationalSymposium on neotropical Magnoliaceaeheld in Ecuador (2015) and co-running theThird International Symposium in cuba in2016 are key features of the MSI’s work.

Ex situ conservation too is of significantimportance: 50% of species are found inex situ collections, while 22 species notincluded in 2007 are now safeguarded.As well as ScBG, there are manycollections of note in china including thekunming Institute of Botany andkunming Botanical Garden. ProfessorSun Wei-Bang has been successfullypropagating several species that arecritically Endangered or Endangeredenabling the reintroduction of Magnoliadecidua and Magnolia sinica in particularback into their native habitats.

FOREWORD

Magnolia sieboldii (Arboretum Wespelaar)

In the Uk, organisations including theRoyal Horticultural Society, PlantHeritage, RBG kew, The Rhododendron,camellia and Magnolia Group and theInternational Dendrology Society all havesubstantial collections in their own or theirmembers’ gardens that are open to thepublic. In mainland Europe, both theArboretum Wespelaar in Belgium andParco Botanico del Gambarogno(ParcoEisenhut) in Switzerland holdsignificant collections, while the latter isone of the world’s major suppliers ofcultivated magnolias. Substantial ex situcollections are also found in new Zealandand north America while the MSI holdsthe registration page for the Internationalcultivar Registration Authority.

This Red List of Magnoliaceae ablybrought together by BGcI highlights thehuge amount of work that is being carriedout around the world. At the same time, itprovides a focus on how many habitatsare ‘vulnerable’ as magnolias are keyconstituents of forest habitats. Bypublishing this, it will publicise thesignificant amount of work that is beingundertaken around the world bypassionate people yet at the same timestimulate a wider audience to support this.

The evaluation of the conservationstatus of all species in theMagnoliaceae has long been a

global conservation priority recognised by Botanic Gardens conservationInternational (BGcI). Since the publicationof The Red List of Magnoliaceae in 2007,93 new Magnolia species have beendescribed, additional information onexisting species has been published inbotanical literature, and new threats tospecies have emerged. In light of this newinformation, and with 93 new speciesrequiring conservation assessments, wehave compiled an updated and extendedversion of The Red List of Magnoliaceae.

The new Red List of Magnoliaceaecontains conservation assessments for304 Magnoliaceae species. Allassessments are also submitted forpublication on the IUcn Red List ofThreatened Species. These assessmentsshow that a large proportion ofMagnoliaceae species are threatenedwith extinction in the wild (at least 48%).nearly one third of all species are still toopoorly known to make a conservationassessment. Overall, only one in fivespecies of Magnoliaceae is considerednot threatened.

The main centre of species diversity forMagnoliaceae is in china, however thereis a second centre of diversity in theneotropics where a large number of newspecies have been recently described andpublished. The neotropics has the highestproportion of threatened Magnoliaspecies; 75% of the neotropical Magnoliaare under threat.

The main threats to Magnolia areextensive logging, both selective andmore general, together with habitat loss

due to agriculture and livestock farming.Sustainable forestry practices and moreprotected areas are urgently needed toconserve Magnolia in the wild.

A survey of ex situ Magnoliaceaecollections was also carried out as partof this conservation assessment. Atpresent, only 43% of threatenedMagnolia species are represented in exsitu collections, falling significantly shortof requirements under Target 8 of theGlobal Strategy for Plant conservation.The majority of threatened Magnoliaspecies are only found in a very smallnumber of collections (fewer than five).However, considerable progress hasbeen made since the last ex situ survey ofMagnoliaceae in 2008, with 22 speciesthat were then absent from ex situcollections now safeguarded in botanicgardens and arboreta worldwide.

The Red List of Magnoliaceae aims tostimulate conservation action forMagnolia species under threat. BGcI andthe Global Trees campaign work withbotanic gardens and other conservationpartners to enhance ex situ conservationfor globally threatened Magnolia taxawhere appropriate and to promote in situconservation planning, ecologicalrestoration and sustainable use.

The Red List of Magnoliaceae

EXEcUTIVE SUMMARy

Magnolia biondii (Arboretum Wespelaar)

Magnolia sprengeri (Arboretum Wespelaar)

The magnolia family, Magnoliaceae, isfound in temperate and tropical regions ofEastern and Southeast Asia, and theAmericas. The Magnoliaceae consists ofover 300 species in two genera –Magnolia L. and Liriodendron L. They areevergreen or deciduous trees and shrubs.Many species are widely appreciatedaround the world as ornamental trees dueto their attractive flowers and foliage. In thewild, these plants are also widelyappreciated, and used for timber andmedicines by local communities as well asin international trade. There areconservation concerns for many of thespecies in the wild due to threats such ashabitat destruction, overharvesting fortimber and medicinal uses, and lownatural regeneration. In order to assessthe impact of these threats on the world’sMagnoliaceae species, there is a need fora global assessment of their conservationstatus to guide conservation action.

The evaluation of the conservation status of trees has long been a global conservation priority recognised by Botanic Gardens conservationInternational (BGcI). BGcI, in partnershipwith Fauna & Flora International,coordinates the Global Trees campaign(GTc). GTc is a joint initiative to safeguardthe world’s threatened tree species fromextinction. Part of the task of GTc is toassess the conservation status of trees inthe wild and in ex situ collections – and insuch a way prioritise species in need ofconservation action. BGcI, working withthe IUcn/SSc Global Tree Specialist Group(GTSG), has for the last eight years beenworking towards this goal, producing globalconservation assessments of trees bothwith taxonomic and regional foci (Table 1).These tree conservation assessmentscontribute directly to the Global TreeAssessment (GTA), which aims to haveconservation assessments for all trees by2020 (Box 1, newton et al. 2015).

The first of such Red Lists was The RedList of Magnoliaceae produced in 2007(cicuzza et al. 2007). Since thispublication, new information on existingtaxa has been published and new threatshave emerged. In addition, since 2007,93 new Magnolia species have beendescribed and published (IPnI 2015).

The majority of these are from theneotropical region. In the light of this newinformation and new taxa, it is now timeto produce an updated and extendedversion of The Red List of Magnoliaceae.

Global Tree Assessment (GTA)

Despite the importance of trees, many arethreatened by over-exploitation and habitatdestruction, as well as by pests, diseases,drought and their interaction with global climate change. In order to estimate theimpact of such threats to trees there is an urgent need to conduct a completeassessment of the conservation status of the world’s tree species – the GlobalTree Assessment.

The Global Tree Assessment aims to provide conservation assessments of allthe world’s tree species by 2020. The assessment will identify those tree speciesthat are at greatest risk of extinction. The goal of the Global Tree Assessmentis to provide prioritization information to ensure that conservation efforts aredirected at the right species so that no tree species becomes extinct.

The Global Tree Assessment is an initiative led by BGcI and the IUcn/SScGlobal Tree Specialist Group. Work is ongoing to develop an even moreextensive global collaborative partnership, involving the coordinated effort ofmany institutions and individuals. These steps will enable the Global TreeAssessment to achieve its 2020 target.

TAXoNomIC SCoPE AND

CoNCEPTS

All species in the family Magnoliaceaethat were published prior to December2015 were included in this assessment.We focused on species-levelassessments, as the IUcn Red List ofThreatened Species only acceptsinfraspecific conservation assessmentsonce a species-level assessment hasbeen carried out. Infraspecific taxa werenot included, unless the taxonomicconcept was unresolved and there weredata indicating that the taxon might beconsidered an accepted species. Hybridswithin Magnoliaceae were not assessed.

The taxonomic concepts followed arethose reflected in The Plant List version1.1 (The Plant List 2013); new speciesdescribed since then as well as taxonomicupdates since 2013 were includedfollowing the World checklist of SelectedPlant Families (WcSP 2016) and afterconsultation with taxonomic experts.

Plant authority names followed thosefrom The International Plant names Index(IPnI 2015).

CoNSERVATIoN ASSESSmENT

mEThoDoLoGY

conservation assessments wereconducted following the IUcn Red List ofThreatened Species categories andcriteria version 3.1 (IUcn 2001, Appendix5). Assessments were compiled using theIUcn’s Species Information Service (SIS),which is a web-based database forstoring and managing IUcn conservationassessments. Information for eachspecies was assembled for a range ofareas including:

• Distribution • Population • Habitat and ecology • Threats • Uses • conservation • References

A wide range of resources were consultedto gather all the required information.Sources include: national and regionalfloras, taxonomic databases, scientificpapers, published and unpublishedreports, expert knowledge, herbariumrecords and national red lists. In addition,expert opinions were consulted at the 1stInternational Symposium on NeotropicalMagnoliaceae held in Puyo, Ecuador inJuly 2015.

Using all the available information, aconservation category was assigned.Species were assigned one of ninecategories: Extinct (EX), Extinct in theWild (EW), critically Endangered (cR),Endangered (En), Vulnerable (VU), nearThreatened (nT), Least concern (Lc),Data Deficient (DD) and not Evaluated(nE) (Figure 1). cR, En and VU are thethree threatened categories. Taxa that didnot qualify for a threatened category, butwere close to qualifying for, or are likelyto qualify for, a threatened category in thenear future, were assigned to thecategory nT. Lc was used for speciesthat are assessed but are not consideredthreatened including widespread speciesand rare but stable species. The use ofthe category DD is discouraged, but maybe assigned to poorly known taxa.Species not yet evaluated were classifiedas nE. In this report nT and Lc taxa wereconsidered “not threatened”.

METHODOLOGy

Figure 1. Structure of the IUCN Red List Categories (version 3.1) (Credit: IUCN)

Magnolia jardinensis (Marcela Serna)

In order to assess whether a speciesbelongs to a threatened category (cR, En,VU), the species were evaluated in relationto five criteria: A) Population reduction; B)Geographic range; c) Small populationsize and decline; D) Very small or restrictedpopulation; and E) Quantitative analysis.The criteria are based on a set ofthresholds and subcriteria. Extensiveguidelines available to facilitate theprocess for the conservation assessorswere consulted (IUcn Standards andPetitions Subcommittee 2014). Inpractice, most assessments were basedon population size and/or range size,either observed, estimated, projected,inferred or suspected. Assessors areencouraged to evaluate taxa using all fivecriteria, but a taxon only needs to fulfil oneof the five criteria to qualify for athreatened category. When several criteriawere met resulting in different statusassessments, the precautionary principlewas applied and the most threatenedcategory was assigned (IUcn 2001).Once completed and reviewed, theassessments were sent for publication tothe IUcn Red List of Threatened Species(IUcn 2015).

All assessments in this report wereassessed on a global scale. Assessmentscarried out by national red list efforts,were only included if species werecountry endemics (i.e. the nationalassessment covered the full geographicaldistribution).

REVIEW AND EVALUATIoN

Wherever possible, expert opinions weresought for all species assessed.Sometimes experts carried out theconservation assessment for their ownspecies (assessors), and sometimes theycontributed data for the conservationassessment to be carried out(contributors). In accordance with IUcnRed List regulations, all assessmentswere also reviewed by a member of theGTSG (reviewer).

Magnolia wolfii IN CoLomBIA

nearly all of colombia’s 33 Magnoliaspecies, many of which are endemic, arethreatened with extinction, as a result ofhabitat loss and extraction for their high-quality timber. BGcI has been workingwith in-country partners Jardín Botánicode Medellín Joaquín Antonio Uribe(JAUM) and Jardín Botánico UniversidadTecnológica de Pereira (JBUTP) tocounteract the impact of these threatsthrough a series of integrated in situ andex situ conservation measures.

Since 2013, work has focused onMagnolia hernandezii, Magnolia gilbertoi,Magnolia jardinensis, Magnolia silvioi andMagnolia wolfii. All these species haverestricted distributions and extremelysmall populations, but none more so than

M. wolfii. This species is only known froma single location, in the Risaraldadepartment in west colombia, where thepopulation is down to fewer than tenmature trees.

Despite its critically Endangeredconservation status, however, workcarried out by BGcI and its in-countrypartners is ensuring that M. wolfii will havea more secure future. Propagationmaterial collected from the wild populationhas been used to establish ex situ seedand living plant collections of M. wolfii atfive botanic gardens in colombia. Duringthese surveys, project staff discoveredanother three mature M. wolfii trees – avital boost to the species’ tiny population.

In addition to building up ex situcollections, work has been underway toreinforce existing wild populations of M.wolfii. In 2013, 400 nursery-grown

seedlings were transferred to MarcellaBotanical Garden which is close to thelocation of the only known wildpopulation. Botanists have carried outrepopulation trials to evaluate the species'growth responses under different habitatand light conditions. This work hasinvolved the cooperation of local farmers,with 5,000 saplings of M. wolfii and otherMagnolia species planted on their land.During the trial plantings, farmers andprotected area staff participated inworkshops providing vital training incollection, propagation and recoverytechniques for Magnolia species. Abroader education campaign at JBUTPcommunicated colombia’s uniqueMagnoliaceae diversity and the need forits conservation to the 10,000 visitors itreceives at its botanic garden each year.

At the same time, JAUM succeeded insecuring the inclusion of a 140ha area oftropical forest, located on the easternslopes of colombia’s Western cordillera,within the colombian Association of civilSociety natural Reserves. This area wasidentified during field surveys as ahotspot for Magnolia species, and it ishoped that its designation will continue to encourage local participation indeveloping and implementingconservation measures for M. wolfii andcolombia’s other threatened Magnolia.

CASE STUDY 2: CONSERVATION OF THREATENED Magnolia

sinostellata IN ZHEJIANGPROVINCE, CHINA

Since Magnolia sinostellata was firstdescribed in 1989, this highly attractivespecies has become a popularhorticultural plant. Its popularity hasproved to be its undoing, however, aswidespread harvesting of specimensfrom wild populations for use incommercial nurseries has seen thespecies rapidly decline. Today only threesmall populations of M. sinostellataremain in the wild, in the mountains ofZhejiang province, south-east china.These populations are all showing signsof poor reproductive performance, whichis further accelerating the species’decline and limiting the genetic diversityof each population.

In 2015, BGcI and staff from Fairy LakeBotanical Garden, Shenzen, initiated aproject to bring M. sinostellata back fromthe brink. The project is taking anintegrated approach, with plans toestablish ex situ living collections and toreinforce wild populations of the species.By the end of 2015, project staff hadalready successfully propagated 2,800M. sinostellata individuals, bolstering thespecies’ limited seed output with graftingand cutting techniques.

A key part of the project is to continueenabling local people to harness thehorticultural and economic value of M.sinostellata without further endangeringwild populations. To this end, 2015 sawthe launch of a series of workshops andtraining courses designed to train localpeople and forest agency staff inpropagation and cultivation techniquesfor M. sinostellata, with more workshopsplanned for 2016. Work is also underwayto develop two cultivars of M. sinostellata

specifically for cultivation purposes.Building local capacity in horticulturaltechniques will reduce their dependenceon wild populations of M. sinostellata,and allow the species to recover.

As well as reducing human pressure on M.sinostellata, plans are also in place toreinforce wild populations with individualsgrown in ex situ collections. Efforts willfocus on a population located on Mountyandang in the south-east of Zheijangprovince. This population has been singled

out as requiring the most urgentconservation action as it currentlycomprises just 3-5 individuals, and is themost genetically distinct population of thethree. Mount yandang is also a populartourist destination, and provides an idealopportunity to publicise the project andraise awareness of M. sinostellataconservation. Meanwhile, monitoring of thehealth and status of all three wildpopulations will continue, along withsurveys to identify any new, as yetundocumented populations of this species.

CASE STUDY 3: MAGNOLIACUBENSIS SSP. ACUNAE:

A FLAGShIP SPECIES FoR ThE

RESToRATIoN oF CUBAN CLoUD

FoRESTS

Magnolia cubensis ssp. acunae isendemic to the montane rainforests ofcuba’s Guamuhaya mountains. Forestclearance has destroyed much of itshabitat, with most of its former range nowoccupied by coffee plantations, shadedby non-native invasive tree species. Allremaining populations of M. cubensisssp. acunae are located in highlyfragmented or degraded habitat. Thelargest population lies outside anyprotected area boundaries, which puts itat permanent risk of clearing for furthercoffee plantations.

The rapid decline of M. cubensis ssp.acunae and other local trees also has widerrepercussions for local ecosystems and thecommunities living within them. TheGuamuhaya cloud forests, of which M.cubensis ssp. acunae was once a majorcomponent, play an important regulatingrole, capturing rainwater and humid air andthus controlling soil erosion, run-off andflooding further down the watershed. This

ecosystem service is vital to thesustainability of the local coffee industry,but with the disappearance of much of thenative cloud forest, such systems are atrisk of breaking down altogether.

Since 2009, BGcI has been working within-country partners the national BotanicGardens Havana and the cubanBotanical Society to address the declinein coverage and quality of the cloudforests in Guamuhaya. As a previouslydominant structural cloud forest specieswhich is classified as criticallyEndangered, and a highly attractive treevalued locally for its timber, M. cubensisssp. acunae acts as a strong flagshipspecies for this project.

Extensive field surveys have been carriedout to map the full distribution of M.cubensis ssp. acunae and to collectpropagation material for establishing thefirst ex situ collections for the species. Amajor challenge in establishing ex situcollections of cloud forest species suchas M. cubensis ssp. acunae is that theyrequire very different conditions to thosefound in established botanic gardens incuba. However, the project partnerscame up with a way of establishing exsitu collections of M. cubensis ssp.acunae that also facilitated the species’conservation in the wild.

With the cooperation of local farmers,native plant nurseries have beenestablished on coffee farms, with traininggiven to coffee farmers and farm workersto enable them to propagate and growM. cubensis ssp. acunae and otherthreatened native trees. The programmehas expanded rapidly, and by 2013,propagation efforts of 12 local nurserieshad raised over 1,500 individuals of M.cubensis ssp. acunae. Having started theprocess of controlling and eradicatingnon-native invasive trees from coffee

plantations, project staff and local farmershave been able to reinforce wildpopulations of M. cubensis ssp. acunaethrough planting out nursery-grown treeson the coffee plantations, in place of thenon-native tree species.

In addition to practical interventions torestore M. cubensis ssp. acunae, projectpartners have worked hard to raiseawareness among local communities ofthe benefits of conserving native treespecies and cloud forest habitats. InAugust 2013, an environmental festival“Del Monte Soy” was held in Topes decollantes to celebrate the relationshipbetween humans and plants, highlight thevalue of the local flora, and tocommunicate the threatened conservationstatus of many native plants in the region,including M. cubensis ssp. acunae. Oneof the key focuses of the trainingworkshops held with coffee farmers wasalso the importance of native tree speciesand habitats for local communities.

Work to conserve M. cubensis ssp.acunae and its native habitat is set tocontinue into the future. One of the latestdevelopments has been the provision oftoolkits to coffee farmers to help them tomanage their native tree nurseriesindependently. Two project workerscontinue to be available to provide advice,but it is the farmers and their communitieswho will lead the work to conserve M.cubensis ssp. acunae into the future.

The Red List of Magnoliaceae

Magnolia cubensis ssp. acunae

Magnolia cubensis ssp. acunae

ThREAT STATUS

All species in the family Magnoliaceaepublished prior to December 2015 areincluded in this Red List assessment,totalling 304 species, which makes this Red List of Magnoliaceae the mostcomprehensive analysis of the family.

Globally, 147 species were consideredthreatened. Sixty species wereconsidered not threatened (Leastconcern and near Threatened). Theremaining species, (97) were DataDeficient (Figure 2). Data Deficientspecies may be either threatened or notthreatened when a full assessment is possible. The recommendation forreporting this uncertainty is to give a range,which means that the proportion ofthreatened species is between 48-80%.

More detailed summary results are foundin Table 2. none of the species wereconsidered Extinct, although two specieswere considered possibly extinct (Magnoliadixonii and Magnolia emarginata). Amongthe 60 not threatened species, there were

13 species assessed as near Threatened(nT), these were species that nearly fall intoa threatened category. One example isLiriodendron chinense this species is underpressure across its range from acombination of factors including habitatdecline, degradation and fragmentation, aswell as issues resulting from hybridisationand poor regeneration, with subsequentpopulation reduction.

Eleven infraspecific taxa were alsoassessed, but not included in thespecies-level analysis (Appendix 3a).More information on these can be foundon the IUcn Red List of ThreatenedSpecies website (www.iucnredlist.org).

Ten species, published recently were notevaluated (nE), as no information onthese species (including the paperswhere the species were described) couldbe accessed (Appendix 3b).

CRITERIA USED

In order to list a species as threatened allfive criteria should be used, although onlya single criterion needs to be met for aspecies to be considered threatened.However, for many plant species thereare not sufficient data available to allowall the criteria to be used. Most (77%)threatened species were assessed usingcriterion B, i.e. listed as threatened dueto their restricted geographic range (Table3). A quarter (26%) of threatened speciesused criteria c and D, which are basedon small or restricted population size.Only 9% of threatened species werelisted using criterion A, which shows thatpopulation reductions (and generationlength) are difficult to calculate for theselong-lived taxa. no species wereevaluated using criterion E (quantitativeanalysis of extinction risk).

Most species were listed using a singlecriterion, but 16 (11%) threatenedspecies had multiple criteria applied.

GEoGRAPhICAL ANALYSIS

Magnoliaceae species were found in 47countries (Figure 3, Appendix 2). Thecountry with the most species was chinawith 108 species (33 threatened),followed by Vietnam with 45 species (14 threatened). Seven of the ten mostspecies-rich countries were located in East and Southeast Asia. Anothercentre of diversity was in the neotropics,with colombia, Mexico and Ecuador

having a very high number of Magnoliaspecies. nearly two thirds (198) ofspecies were single country endemics.

When comparing the proportion ofthreatened species, the neotropics(Mexico, colombia and many of thecaribbean islands) showed a very highproportion of threatened species (Figure4). For most countries in the neotropics,with only a few exceptions (Brazil,

Panama, El Salvador and nicaragua),more than 50% of their Magnolia specieswere considered threatened.

As a whole, 75% of the neotropicalMagnolia were considered under threat;and the neotropics have more than twothirds of the world’s most threatenedMagnolia species – those found incategories critically Endangered andEndangered.

mAjoR ThREATS

The majority of Magnoliaceae specieswere found in subtropical or tropicalforests, with a few species found intemperate climates. A range of threatshave been recorded, associated bothwith the species as well as the habitat inwhich they grow. The threats wererecorded using the IUcn threatclassification scheme (IUcn 2012).

The most common threats toMagnoliaceae are shown in Figure 5.Logging/wood harvesting was the mostsignificant threat to all Magnoliaceaespecies, both threatened and notthreatened. It impacted nearly half (44%)of all species. Impacts from agriculture(annual and perennial non-timber crops)accounted for the second biggest threatand was identified as a significant factorin over one third of all species (36%).Habitat loss due to livestock farming andhuman development were also significantfactors. Other threats included collectionsof wild plant material and climate change.

PoPULATIoN TRENDS

The population trend for each assessedMagnoliaceae species was also recordedas part of the conservation assessmentprocess. These data showed that less than5% of species have a stable or increasingpopulation; 42% of species have adocumented decreasing population (Figure6). For more than half of the speciesassessed, the population trend was notknown. This lack of information onpopulation trends can lead to speciesbeing assessed as Data Deficient.

RED LIST oF mAGNoLIACEAE

The Red List of Magnoliaceae (cicuzza etal. 2007) included 151 Magnoliaceaetaxa, of which 120 were species-levelassessments (Table 4). This new Red Listupdate contains 304 species. 107species from the original publication wereassessed again. The 13 species whichwere not evaluated again are nowconsidered synonyms, and the acceptedname has been listed instead.

Of the 107 reassessed species, most (78species) had the same conservationassessment category. However, 29 hada different rating: 12 species were given ahigher category of threat, while tenspecies were moved from Data Deficientto another conservation rating. Sevenspecies were categorised as lessthreatened (i.e. a lower category ofthreat), but none of these species fell outof a threatened category.

compared to the 2007 publication, the2016 Red List of Magnoliaceae lists 52additional species that have beenidentified as at risk of extinction. Thereare also 44 additional species that havebeen identified as not at risk of extinction,and, worryingly, 88 species that haveinsufficient information to assess theirconservation status.

Magnolia laevifolia

In addition to the conservationassessments, we also carried out an exsitu survey to assess the representationof Magnoliaceae species in ex situcollections of botanic gardens, arboretaand seed banks around the world.

All Magnoliaceae records weredownloaded from BGcI’s globaldatabase of plants in cultivation -PlantSearch (Box 2) (as of 26 January2016). In addition, lists of ex situ Magnoliacollections sent to us from specialistcollections not on PlantSearch and thechinese checklist of ex situ cultivatedflora (Huang 2014) were consulted.

The ex situ survey identified 9,918 recordsof Magnoliaceae from 490 institutions(Table 5). This number represents thepresence of a single taxon in a collectionwithin an institution and does not take intoaccount the number of accessions orindividuals. Only species records wereincluded in the analysis; records ofcultivars or infraspecific taxa wereexcluded. In total 4,476 records matchedwith Magnoliaceae species included inthis Red List or with synonyms.

SPECIES IN EX SITU CoLLECTIoNS

Exactly half of all Magnoliaceae species(152 of 304 species) are found in ex situcollections. However, species in ex situcollections are often (82 of 152) thoselisted as Least concern or Data Deficient(Figure 8). Only 43% (63 of 147) ofthreatened Magnolia species (criticallyEndangered, Endangered and Vulnerable)are found in ex situ collections (Figure 7),well below Target 8 of the Global Strategyfor Plant conservation which calls for 75%of threatened plants to be held in ex situcollections (cBD 2012).

PlantSearch

BGcI’s PlantSearch database is the only global database of plants in cultivation.It is available online, and it is free to contribute to and access. PlantSearchconnects around 2,000 researchers and horticulturists to collections every year.Locations and gardens are not publicly revealed and requests can be made viablind email messages. PlantSearch is an easy way for ex situ collection holdersto contribute to broader ex situ assessments, such as this survey. By uploadinga taxa list to PlantSearch, collection holders can connect their collections to theglobal botanical community and find out the conservation value of their taxa,including the number of locations each taxon is known from globally and itscurrent global conservation status. It is important for institutions with ex situcollections to share accurate data and keep it updated, and PlantSearch relieson collection holders to upload up-to-date taxa lists on an annual basis toensure accuracy and enhance usability of the data.

Twenty-three critically Endangeredspecies not found in collections are listedin Table 6 together with their country ofoccurrence; of these, 20 are endemic tothe neotropics. Successful efforts havebeen made by BGcI to target threatenedMagnolia species in these regionspreviously (See case Studies 1 and 3).Further efforts should be made to bring theremaining critically Endangered speciesinto collections as soon as possible.

CoLLECTIoNS

Sixty-two percent (39 of 63 species) ofthreatened Magnolia species are found ina very small number of collections (fewerthan five collections), with the majorityonly found in a single collection (Figure 8).Species found in only a few collectionsdo not have sufficient protection againststochastic events or loss from naturalcauses. Furthermore, small collectionnumbers are unlikely to capture sufficientgenetic diversity to enable the collectionsto be used in restoration or reintroductionprogrammes.

In contrast, some species arewidespread among botanic gardens andarboreta around the world (Table 7).These species are generally considerednot threatened, one exception beingMagnolia stellata, which is listed asEndangered in the wild and is present inover 200 ex situ collections and is alsowidespread in general horticulture. Thequality of ex situ Magnolia collections, interms of size of collections and geneticdiversity, is not included in the remit ofthis survey. It will be important to considerthese two factors when bringing newspecies into collections, to maximise theconservation value of the ex situcollection. Further work on the geneticcomponents and relevance of ex situcollections have been carried out forMagnoliaceae (cires et al. 2013), and inmore detail for other groups (i.e. Griffithet al. 2015).

SURVEY oF mAGNoLIACEAE

A comparison of the results from thissurvey with those of an ex situ survey ofMagnoliaceae carried out in 2008 (BGcI2008) show an increase in the number ofrecords of Magnoliaceae in ex situcollections of 7,644. This is due in part todata being provided from a further 252institutions from 14 additional countries.But importantly Magnoliaceae speciesare now better conserved in ex situcollections. In addition, there are 22species that were not present incultivation in 2008 that are now availablein ex situ collections (Table 8). This showsthe impact and importance of the RedList assessments and the subsequent exsitu survey highlighting and prioritisingconservation action.

PoLICY RELEVANCE

This new Red List of Magnoliaceaecontributes directly to Target 2 of theGlobal Strategy for Plant conservation ofthe convention on Biological Diversity,which calls for “an assessment of theconservation status of all known plantspecies, as far as possible, to guideconservation action” by 2020 (cBD 2012).In addition, an assessment of threatenedspecies is also needed to ensure thatTarget 8 of the Global Strategy for Plantconservation is met. This target calls for“at least 75 per cent of threatened plantspecies in ex situ collections, preferably inthe country of origin, and at least 20 percent available for recovery and restorationprogrammes” (cBD 2012).

The Red List of Magnoliaceae aims tostimulate conservation action forMagnolia species under threat. The aimis for these conservation assessments forMagnoliaceae to guide conservationaction and policy decisions for the veryrare and threatened species. The priorityis to protect Magnolia in their naturalhabitats. Many of the most threatenedspecies are still absent from ex situcollections, and should also be prioritisedfor targeted collection efforts.

BGcI and the Global Trees campaignwork with botanic gardens to enhance exsitu conservation for globally threatenedMagnolia taxa where appropriate and topromote in situ conservation planning,ecological restoration and sustainableuse. More information about theseprojects are available online(www.globaltrees.org/projects).

RECommENDATIoNS

The Red List of Magnoliaceae is a steptowards the Global Tree Assessment (GTA)which will provide information on the threatstatus of all the world’s trees. In order toachieve the GTA and, more specifically,

improve the conservation status forMagnoliaceae, a number of conservationmeasures are recommended:

Collect more information on Data

Deficient species:

• More information is needed on thelarge proportion of species for whichthere was not enough data to assesstheir conservation status (listed asData Deficient).

• Report any known information onthese species to [email protected] toallow a full assessment to take place.

• Target fieldwork and data collectionfor priority regions where thesespecies occur.

Ensure threatened species of

magnoliaceae are conserved in situand ex situ:

• Develop ex situ conservationcollections for the threatenedMagnoliaceae species not yetrepresented in any ex situ collections.

• Wherever possible, house ex situcollections in more than oneinstitution and location.

• Ensure genetic diversity is taken intoaccount when building ex situcollections.

• Assess the extent to which speciesare included in protected areas.

• Develop integrated conservationaction plans for the most threatenedspecies.

Raise awareness and build capacity

locally and internationally:

• Empower and inform communitiesabout the uniqueness andimportance of the Magnoliaceaespecies found in their localenvironment.

• Use local plant nurseries and plantingschemes to enhance the status ofthe most threatened Magnoliaspecies in the wild.

• Build horticultural capacity of in-country partners and localcommunities, including protocols forcollection, propagation and cultivation.

There has been significant progress sincethe last Red List of Magnoliaceae wasproduced in 2007: more Magnoliaspecies have been discovered anddescribed, more Magnolia species have aconservation assessment, and moreMagnolia species are now conserved inex situ collections. nevertheless, muchmore needs to be done in order to savemany Magnolia species from extinction.Future work should focus on therecommendations above, and use theinformation gathered in this publication toeffectively prioritise conservation action.

It is a very rangerestricted species, with an extent ofoccurrence (EOO) of 85 km2 at threelocations. This species is threatened bysevere habitat fragmentation andcontinuing decline in extent and quality ofits habitat by an increase of pasturelands, firewood extraction, coffeeplantations and human settlements. Thisspecies is listed as Endangered.However, very little is known about thisspecies and more research is necessary.

Magnolia wendtii A.VázquezcR B1ab(iii)MexicoMagnolia wendtii is only known from asingle collection at the type locality inVeracruz, Mexico. It is extremely rare anddespite intensive explorations in theUxpanapa and chimalapa region, noadditional records of this species havebeen made since it was first found in1982. The extent of occurrence (EOO) isestimated to be less than 100 km2 andthe area is currently undergoing severedeforestation for conversion to pasturelands. This species is listed as criticallyEndangered.Assessors: Rivers, M.c., Samain, M.S. &Martínez Salas, E.

Magnolia wetteri A.VázquezEn B1ab(iii)Costa RicaMagnolia wetteri is a large tree restrictedto the southern part of costa Rica whereit is only known from the Osa peninsula.Its estimated extent of occurrence (EOO)is between 40 and 1,600 km2 and it isthought to occur in fewer than fivelocations. Logging has been recorded inthe area where this species is found,which is thought to be causing acontinuing decline in the area and qualityof habitat for this species. Therefore,Magnolia wetteri is assessed asEndangered.

The Red List of Magnoliaceae

EXTINCT (EX)

A taxon is Extinct when there is no reasonable doubt that the lastindividual has died. A taxon is presumed Extinct when exhaustivesurveys in known and/or expected habitat, at appropriate times(diurnal, seasonal, annual), throughout its historic range have failedto record an individual. Surveys should be over a time-frameappropriate to the taxon’s life cycle and life form.

EXTINCT IN ThE WILD (EW)

A taxon is Extinct in the Wild when it is known only to survive incultivation, in captivity or as a naturalized population (or populations)well outside the past range. A taxon is presumed Extinct in the Wildwhen exhaustive surveys in known and/or expected habitat, atappropriate times (diurnal, seasonal, annual), throughout its historicrange have failed to record an individual. Surveys should be over atime-frame appropriate to the taxon’s life cycle and life form.

CRITICALLY ENDANGERED (CR)

A taxon is critically Endangered when the best available evidenceindicates that it meets any of the criteria A to E for criticallyEndangered (see Section V), and it is therefore considered to befacing an extremely high risk of extinction in the wild.

ENDANGERED (EN)

A taxon is Endangered when the best available evidence indicatesthat it meets any of the criteria A to E for Endangered (see SectionV), and it is therefore considered to be facing a very high risk ofextinction in the wild.

VULNERABLE (VU)

A taxon is Vulnerable when the best available evidence indicates thatit meets any of the criteria A to E for Vulnerable (see Section V), andit is therefore considered to be facing a high risk of extinction in the wild.

NEAR ThREATENED (NT)

A taxon is near Threatened when it has been evaluated against thecriteria but does not qualify for critically Endangered, Endangered orVulnerable now, but is close to qualifying for or is likely to qualify fora threatened category in the near future.

LEAST CoNCERN (LC)

A taxon is Least concern when it has been evaluated against thecriteria and does not qualify for critically Endangered, Endangered,Vulnerable or near Threatened. Widespread and abundant taxa areincluded in this category.

DATA DEFICIENT (DD)

A taxon is Data Deficient when there is inadequate information tomake a direct, or indirect, assessment of its risk of extinction basedon its distribution and/or population status. A taxon in this categorymay be well studied, and its biology well known, but appropriatedata on abundance and/or distribution are lacking. Data Deficient istherefore not a category of threat. Listing of taxa in this categoryindicates that more information is required and acknowledges thepossibility that future research will show that threatened classificationis appropriate. It is important to make positive use of whatever dataare available. In many cases great care should be exercised inchoosing between DD and a threatened status. If the range of ataxon is suspected to be relatively circumscribed, and a considerableperiod of time has elapsed since the last record of the taxon,threatened status may well be justified.

NoT EVALUATED (NE)

A taxon is not Evaluated when it is has not yet been evaluatedagainst the criteria.

ThE CRITERIA FoR CRITICALLY ENDANGERED,

ENDANGERED AND VULNERABLE
