Considerations for DesigningRiparian Restoration for Wildlife
in Californias Central ValleyBy Dan Efseaff, Stacy Small and Nick Pacini, River Partners
I. Introduction
California riparian areas host some of the highest animal biodiversity in the state. While the number of
plant species that line lowland rivers may be relatively few, the vegetative patterns are complex. Trees,shrubs, vines, and herbaceous plants combine to make a unique and extraordinary vegetative structurefound nowhere else. In addition, physical characteristics such as flood events, heterogeneous soils,
abundant water, multi-level terraces and other factors produce a complex mosaic across the landscape,with dense forest abutting open grasslands. In short, many wildlife populations depend on healthyriparian corridors.
By the 1980s, only a small percentage of historic riparian forests remained in the Central Valley.Conversion of forest to agricultural lands, urban development, water diversions, dams, and other
human influences have all conspired to remove forests and degrade the remaining habitat (Katibah1984). Not surprisingly, the loss of forest has precipitated the decline in a host of riparian-dependent
wildlife. A variety of creatures from Chinook salmon (Oncorhynchus tshawytscha) to Yellow-billedCuckoo (Coccyzus americanus occidentalis) to the valley elderberry longhorn beetle (Desmocerus

This field was once planted as row crops. Agricultural techniques have been employed
on a large scale to restore it back to native riparian habitat. Here, native grasses are
being drill-seeded in to establish an herbaceous understory. With good site conditions
and proper maintenance, horticultural success can be achieved in a short period of time.

californicus dimorphus), depend on riparian zones for food, shelter, and cover in
sometimes complex ways that are still being investigated.
In response to these imperiled wildlife populations, agencies and organizationsinitiated efforts to acquire and protect existing riparian habitat along theSacramento and San Joaquin Rivers. Yet looking across the fragmented slivers of
remaining habitat, conservationists recognized that stable wildlife populationswould require far more effort than the preservation of existing habitat. They
soon realized that recovery of wildlife populations needed to be considered assuccess criteria for riparian restoration. In this article we will discuss ourexperience in the Central Valley with riparian habitat restoration along the
Sacramento and San Joaquin Rivers
Why do we need to actively restore these areas?
On the Sacramento River, after the completion of Shasta Dam, the threat of
damaging floods initially appeared to be greatly diminished, and floodplains
were cleared for agriculture. Soils along the Sacramento River and other majorrivers of California are some of the richest in the state. Abundant soil moisture,
good drainage, and favorable weather make them extremely attractive tofarmers, and while these areas may be productive, they are always at risk of
flooding. Flood events may have been somewhat tamed but many areas close tothe river still flood, with serious consequences for agriculture. Floods bring in
sand, sediment, and pathogens, and drown out crops. With changes in the farmeconomy and crop patterns, farming on these flood-prone parcels becameextremely costly and were often abandoned.
Initial efforts to protect riparian habitat focused on preserving the largest blocksof existing habitat available from willing sellers. Many of these sites included
former agricultural fields, no longer economical to farm due to flooding. The
flooding and proximity to existing riparian habitat encouraged many resourcemanagers to initially believe that riparian plants would reclaim these fallowfields. In low-lying areas that experience frequent flooding this can be the case,
but our experience with areas cleared for agriculture is that they are goodcandidate sites for active restoration. Areas that are close to the river and exposedfully to river processes may be synchronized with riparian plant life cycles and
need little intervention (except for occasional weed control). These former agfields are still exposed to the impressive forces of the river that shape plant
communities, but a little distance or relative elevation is enough to mute theseforces. Furthermore, dams and diversions have altered river hydrographs,
diminishing the ability of some native riparian plants to become established.Weed competition often precludes widespread native plant recruitment.
Therefore, these fallow fields can remain without significant native riparian
plants for decades.
Dams and floodplain barriers have altered the patterns of flood timing,frequency, duration, and magnitude that native plant species have evolved with,preventing succession on these fallow fields. For example, flood-dependent
plants such as Fremont cottonwood require bare soil (typically either scoured ordeposited from a flood event), minimal competition, and slowly receding
floodwaters so thirsty cottonwood roots can tap into deeper soil moisture beforethe onslaught of another hot, dry Central Valley summer arrives.

Because river hydrographs are now soaltered from historic patterns to whichplant populations have adapted, native
plant recruitment on fallow ag fields canbe minimal, despite seemingly ideal
conditions like the cessation ofagricultural practices, frequent flood
events, and availability of nearby seedsources. As adverse hydrologic conditionspersist, non-native plants (such as black
mustard, Johnson grass, perennialpepperweed, and yellow star-thistle) are
likely to colonize and dominate fordecades. Over time, native plants (mainly
coyote brush, elderberry, and occasionallynative grasses) may recruit on site, buttheir recruitment rate is likely to remain
slow. Perhaps worse, invasive woodyspecies such as tamarisk, arundo, and tree
of heaven may also colonize the site. At
high numbers, these species provideextremely poor wildlife habitat anddiminish floodwater conveyance.
Over the years, as resource managersstruggled with efforts to reduce the
burden of maintenance on these fallow field properties andprovide high quality habitat, a new paradigm arose the use ofagricultural techniques to plant and establish native plants and set
in motion a new successional trajectory that favored nativeriparian plants and provided wildlife habitat within a short period
of time.
How do we restore riparian habitats?Large scale (over 50 acres) riparian restoration was pioneered onthe Sacramento River in the early 1990s. This approach blends
local agricultural practices with ecological theory in a cost-effective manner. Since then this model has also been applied to
the San Joaquin and other rivers.
With just a fraction of the original riparian forest left, large-scale
restoration has become a very attractive option to fill in the gapsbetween fragmented forests, increase the connectivity of wildlife
habitat corridors, provide breeding and foraging sites, andessentially provide a life support system for riparian wildlifepopulations until more sufficient areas are protected and river
management is more in sync with riparian life cycles. In light ofhuman population encroachment, the areas set aside for habitat
will become increasingly important, and it is critical that therestoration on a site maximizes the investment.
The initial projects implemented with this approach served asdemonstration projects to test the feasibility of utilizing
agricultural practices to establish native riparian plants. As thesetechniques have become increasingly sophisticated, the scale has
increased to projects that exceed 800 acres at a time, and theapproach now includes more refined objectives for wildlife and
other societal benefits, such as flood management and recreation.
Clearly the first priority is to develop planting designs that match
site-specific conditions (soils, hydrology, existing vegetation, etc.),and reference sites are certainly useful in this process. However,
an equally important concern is that restoration projects benefitwildlife. Therefore, restoration designs must consider historic
natural communities, but also take a pragmatic approach toconsider current conditions and habitat requirements of wildlifespecies the projects are intended to benefit.
Wildlife habitat restoration requires a deep understanding ofwildlife species life histories. Identifying appropriate wildlife
target species and restoration sites requires an understanding ofthe species range (current and historic), annual cycle, habitat
requirements (sometimes at multiple spatial scales), competitorsand predators. Working with wildlife ecologists and consulting
published natural history accounts, species recovery plans, andpeer-reviewed scientific literature is all part of the process ofdeveloping an effective habitat restoration plan.
In order to represent a wide cross-section of habitat needs, RiverPartners selects a suite of focal species (or target species) that
the restoration project is intended to benefit over time. Althoughother species are likely to benefit as well, this approach allows us
to design projects with specific habitat features in mind. Forexample, Least Bells Vireo (Vireo bellii pusillus) nests in shrubby
early successional riparian habitat, often near water. The riparianbrush rabbit inhabits dense thickets of riparian shrubs onfloodplains. Juvenile Chinook salmon benefit from woody debris
On the US Army Corps of Engineers McHenry Recreation Area, along the Stanislaus River,River Partners designed and implemented a restoration project that formed a complex
habitat structure after only three growing seasons. This site was a fallow field of weeds
four years ago; it now hosts dense native vegetation used by breeding and wintering
songbirds including Song Sparrows, Common Yellowthroats, and Black-headed Grosbeaks.

and shaded habitat provided by trees and
shrubs growing over the water. Habitatrequirements for multiple species can
often be accommodated in an ecologicalrestoration plan that considers habitatstructure in addition to plant survival. As
new research and monitoring informationaccumulates, we strive to perfect these
designs and incorporate new features thatlend themselves to becoming testable
hypotheses. Our success criteria haveshifted from a primary emphasis on plantsurvival to include wildlife use. For
example, a nesting pair of Least BellsVireos successfully fledged young using
one of our restoration projects at the SanJoaquin National Wildlife Refuge. This
event signified the return of this once-common species to the Central Valley, after a long 60 years
absence. Although they certainly may be related, the detection ofthis species nesting on a restoration site may be a better indicatorof success than high overall plant survivorship.
Our designs typically contain far more plant species diversity thanthe surrounding agricultural landscape, and we spend
considerable effort to determine the structural components of theplanting. For example, to benefit Least Bells Vireo that nest in low
growing shrub cover, we may group roses and blackberriestogether in an area planted with mugwort. To benefit Yellow-billed
Cuckoos, we may create a large stand of cottonwoods with lightgaps and a heavy shrub component.
River Partners often uses a two forest design. That is we plan formultiple successional trajectories to create quality habitat overlong periods of time. Fast growing, early successional species such
as cottonwood and willows are planted to provide rapid vegetativestructure and habitat (5-20 years). Included in the design are
slower growing species such as valley oak. Over the long term, theslower growing oaks will grow through the canopy and become
the dominant species (>25 years). In the meantime, multiplegenerations of birds can benefit from this structural development(please see the article on Beehive Bend, page 9). With this
approach, a transient successional series may dominate untilanother plant community matures.
In other cases, we may create designs in which a riparian shrubcommunity dominates a site over time for the benefit of shrub-
dependent species, such as the riparian brush rabbit (see Life on
the Floodplain article, next page). Wildlife monitoring and
adaptive feedback from land managers and wildlife specialists hasled to restoration designs that focus less on tall trees alone and
more on under- and mid-story species. Native grasses and forbsadd to the food base and cover and effectively out-competeweeds. For example, dense cover of mugwort can make a site
more resistant to weed invasions and provide important habitatfor birds, such as the Song Sparrow (Melospiza melodia),
Common Yellowthroat (Geothlypis trichas) or Lazuli Bunting(Passerina amoena).
ConclusionsSince its genesis over 15 years ago, the goals of riparian
restoration in Californias Central Valley have shifted from simplehorticultural success and plant survival to include wildlife
benefits, as well. Although this pragmatic approach ofmaximizing habitat features for a suite of targeted wildlife species
may not exactly replicate the original habitat found on aparticular site, success is measured by whether wildlifepopulations thrive on the restoration site and whether the
restoration efforts will have a lasting legacy to preserve imperiledwildlife.

The world of the riparian brush rabbit (Sylvilagus bachmaniriparius) is a tangled mess, depending on whose eyes you see itthrough. This species inhabits thickets of California rose (Rosacalifornica), California blackberry (Rubinus ursinus), and sandbarwillow (Salix exigua) that are typical of historic streamsidevegetation of the Central Valley but are now so rare throughout
this species historic range. Like other brush rabbit sub-speciesdistributed throughout shrubby plant communities of California,
such as chaparral and coastal scrub, the riparian brush rabbitprefers low, woody shrub cover and creates a maze of tunnels for
travel through river bottom vegetation. It lives out its entire lifecycle without venturing far out into the open, and its compactbody is adapted to maneuver with great agility through dense
riparian thickets and, in this way, dodge coming prey.However, the dense riparian cover favored by riparian brushrabbits was just the brush least favored by landowners and leveemanagers over the past century and was therefore targeted for
clearing throughout the San Joaquin Valley. Now one of the mostendangered mammals in California, this creature is hardly ever
seen in the wild, both because of its shy, skittish nature and itsrarity.
Life on the floodplain has another set of hazards for a shrub-dwelling rabbit with limited swimming abilities. Frequent
flooding requires the riparian brush rabbit to seek high ground,
preferably a place with vegetative cover where it can wait out aflood event without starving or being preyed upon by hawks
circling above. Such vegetated high ground is in short supply inthis rabbits historic San Joaquin Valley range. The naturaltopography of riparian floodplains has been subject to leveling in
the process of agricultural conversion, which compounds theeffects of land clearing for this species.
To counteract historic land use impacts on this and otherriparian-associated species, River Partners has been collaborating
with the U.S. Fish & Wildlife Service (USFWS) and theEndangered Species Recovery Program (ESRP) at CSU Stanislaus
to design and implement habitat restoration projects for the
benefit of reintroduced riparian brush rabbit populations on theSan Joaquin River National Wildlife Refuge. The primaryrecovery goal for the riparian brush rabbit is to establish threenew self-sustaining sub-populations that can survival stochastic
events. To attain this goal, extensive habitat restoration, inconjunction with ESRPs captive breeding and reintroduction
program, is required.
Following recommendations from ESRP and USFWS, we have
taken a three-part approach to this restoration: 1) planting

shrubby riparian habitat near rabbitreintroduction areas; 2) re-vegetating
natural high ground and Refuge leveesas flood escape corridors; and 3)
constructing new high-ground floodrefugia on Refuge floodplains to restoretopography to formerly leveled fields. In
the process, we seek to provide multi-species benefits through our planting
and flood refugia designs.
To date, we have planted over 1,000
acres of riparian habitat on the SanJoaquin River National Wildlife Refuge(10 miles west of Modesto) and
vegetated 20,000 linear feet of leveeswith native shrubs, with financial
support from USFWS, CaliforniaDepartment of Water Resources,
CalFed, Bureau of Reclamation, WildlifeConservation Board, and the ResourcesAgency. Lately, we have focused on
restoring natural high ground andconstructing earthen mounds and berms that are planted with
native shrub cover for flood refugia sites. Our plantingcomposition for the brush rabbit is high in shrub species,
including California rose, California blackberry, coyote brush(Baccharis pilularis) and sandbar willow, with some blue
elderberry (Sambucus mexicana) and valley oaks (Quercus lobata)included.
Wildlife species that typically co-occur in riparian brush rabbithabitat include Spotted Towhee (Pipilo maculatus), Song Sparrow
(Melospiza melodia) and several species of wintering sparrows,Wrentit (Chamaea fasciata), California Quail (Callipeplacalifornica), and the endangered San Joaquin riparian woodrat(Neotoma fuscipes riparia). Wrentits, Spotted Towhees and SongSparrows nest in dense shrub cover. Riparian woodrats inhabit
areas with willows beneath valley oaks. We also expectNeotropical migrant songbirds, such as Yellow Warblers
(Dendroica petechia) and Black-headed Grosbeaks (Pheucticus
melanocephalus), to nest and forage in the willow patches
incorporated into our most recent designs. Mexican elderberryprovides an important food source for foraging birds and isthe host plant for the endangered valley elderberry
longhorn beetle (Desmocerus californicus dimorphus).
We anticipate benefits for salmonid populations, as well.Creating high-ground flood refugia for terrestrial wildlife
will enable the Refuge to eventually be restored tofunctional floodplain habitat for juvenile salmonid rearing.Also, by planting riparian vegetation near eroding river
banks, we will slow erosion, strengthen river banks, andprovide shade, shelter, and a food supply for aquatic
organisms.
The riparian brush rabbits life history is intricately linked
to floodplains, riparian habitat, and river processes, and itsrecovery will depend upon the restoration of vigorous,
native riparian corridors. Effective restoration for thisspecies is likely to result in a thriving, diverse riparian
wildlife community for the northern San Joaquin Valley.

In 1991, the California Department of Fish & Game (DFG)
acquired a 269-acre parcel in rural Glenn County. The site wasnamed the Beehive Bend Unit after the name of a sweeping curve
along the Sacramento River. A new channel was blasted in theearly 1900s to shorten the distance river boats needed to take,leaving the remnant channel as an oxbow lake. Lining the old
channel was classic Sacramento River riparian forest atowering canopy of valley oak, Fremont cottonwood, Goodings
willow and western sycamore, all draped in a veil of wild grape.Oregon ash and box elder, festooned with Dutchmans pipevine
and poison oak, dominated the mid-story. The understory, likemost places on the river, was a mix of native and non-native
species.
However, in the midst of this lush habitat was approximately 60
acres that had been farmed for at least 40 years. When farming
ceased, this area lay fallow for a decade and vegetation quicklycolonized the rich soils, though few of the plants were native.
Instead, a tangle of yellow star thistle, Johnson grass, and blackmustard dominated the site, providing poor habitat and little
opportunity for forest regeneration.
In 1999, DFG contracted with River Partners to restore the
Beehive Bend Unit. This project came during a critical period inthe evolution of restoration design, and was one of the first to
incorporate a sophisticated plant design based on a mosaic ofvegetative structure designed specifically to maximize the nichesexploitable by native birds. To help evaluate the restoration, River
Partners worked with PRBO Conservation Science to monitor
breeding songbirds in both the remnant riparian and restorationarea, and the project design was developed in part with PRBOrecommendations. What began as a three-year study has now
extended into ten years of monitoring through subsequentfunding efforts. Longer term views are critical to understandingthe efficacy of restoration, as Dr. Nat Seavy of PRBO points out,
because some species do not use restored sites until about 10years after restoration. Monitoring beyond the typical three-year
period is critical for understanding whether or not restoration has
been successful in creating bird habitat.
Riparian habitats are dynamic, yet predictable patterns occur andwildlife responds accordingly. Early-successional habitat includessuch pioneering plant species as willows and blackberry that
colonize new sandbars after flood events, and this vegetativestructure is mimicked by young restoration. Some of the first
avian species to respond to this habitat include Black-headedGrosbeak, Lesser Goldfinch and Spotted Sandpiper. Because
early-successional habitat is in short supply, these birds flock torestoration sites, and have been documented abandoning longheld territories in old riparian in favor of restorations as young as
two years old.
Dams, diversions, and levees have greatly altered floods and
seasonal flows, and as a result, early-successional habitat is nowrarely created by the Sacramento River. Most of the remnant
habitat along the river is comparable to the existing riparian atBeehive Bend, or is in agricultural production. While this can
provide important habitat for some birds, many sensitive birdspecies need a different type of forest, the lush quick growth ofshrubby willows, California blackberry and other rapidly growing
native plants. In the absence of more dynamic rivers, restorationplantings provide important habitat. The trick is how to best
manage these areas for them long term, and this question canonly be answered with long-term monitoring on existing projects
so that we can accurately evaluate their impacts.
So how has Beehive Bend performed over its first decade? Trends
from the 1999-2007 point-count data suggest some interestingresults. In the existing riparian forest, avian species richness has
averaged 9.8 (species per point, over two visits per breedingseason) for the duration of the study, while richness within therestoration hovered around 3.5 over the first four years, and then
jumped to 7.5 in year five and 8.3 in year six. After a one-yearbreak due to lack of funding, the study resumed in 2006 (current
funding will take us through the 2008 field season) and PRBOfound that the restored forest now harbored a bird community
that was nearly as species rich as the existing riparian (richness =9.0 in the restoration, 9.22 in the existing riparian over the nexttwo years).
Looking at Beehive in the context of a larger study, twenty birdspecies were examined over a similar time period across ahundred-mile segment of the lower Sacramento River and twelve
were found to be increasing, while only one was decreasing. Whilethis is great news in an era when so many studies are
documenting negative trends, we must continue to work closelywith our partners to further refine and improve our restoration
designs, working toward a common goal of ensuring the longterm vitality of Californias wildlife.
