1 Introduction
After analysing the connectivity of the ecological network (output 3.1) and defining potential
ecological corridors (wetlands, woodlands and open landscape areas (section 2) different gaps
could be detected. These gaps can be either within a potential corridor of protected areas or outside
the network of protected areas.
2 Designation of potential ecological corridors
For the designation of potential ecological corridors the current land use of the area was not
considered, this was done in later step during the gap analysis where hemeroby indexes were
applied to distinguish the gaps.
2.1 Potential ecological corridors for wetland habitats and mountainous habitats
2.1.1 Methodology for wetland habitats
Data base: River and water network CORINE land cover data Existing transnational and national network plans Ramsar sites
Selection of relevant river and water corridors
Selection of all wetland types from the CORINE land cover data set (table 1)
Table 1: Wetland types and CORINE land cover codes
CORINE land cover code Wetland type
411 Inland marshes
412 Peat bogs
511 Water courses
512 Water bodies
522 Estuaries
Selection of relevant river corridors according to:
- Existing European planning (see annex 1 of report “Inventory of ecological networks”):
Austria, Czech Republic, Poland, Slovakia, Ukraine (PEEN (Pan-European Ecological Networks ) for Central and Eastern Europe)
Italy, Croatia, Slovenia (Connectivity Alps-lowland, „Platform Ecological Network“ of the Alpine Conference – First Meeting 03/2007)
Germany, Austria (Indicative draft map of PEEN for Western Europe)
- Existing national planning (see annex 1 of report “Inventory of ecological networks”):
Germany (German Habitat Corridor Network, BfN, date: 2004)
Poland (Polska National Ecological Network)
Report: Gaps in ecological networks

Hungary (Selection of already existing digital data of ecological important areas along rivers)
Slovenia (Selection of already existing digital data of ecological important areas along rivers)
- Course of the river to Ramsar sites or in the vicinity of Ramsar sites
Buffering of the selected rivers, lakes and CORINE land cover classes by 2000 m
For all buffers (wetlands, woodlands, open landscape areas and protected areas) we used a buffer
distance of 2000 m. This distance has been selected according to PAN (2006) and Bastian and
Schreiber (1999) because a large number of species is able to bridge gaps between habitats,
smaller than 4000 m (2 x 2000 m).
2.1.2 Methodology for mountainous habitats
Data base: Digital surface model
Existing transnational and national network plans
Analysis of ridges (using the software Landserf, a free GIS tool which is available at
http://www.soi.city.ac.uk/~jwo/landserf/)
Selection of relevant ridges (>400 m above sea level)
Identification of the main ridges and other/lower ridges
Buffering the lines by 2000 m (main ridges) resp. 1000 m (other ridges)

2.2 Potential ecological corridors for woodland habitats
2.2.1 Methodology
Selection of all woodland types from the CORINE land cover data set (table 2)
Table 2: Woodland types and CORINE land cover codes
CORINE land cover code Woodland type
324 transitional woodland-shrub
311 broad-leaved forest
312 coniferous forest
313 mixed forest
Buffering all woodland types with an outer or positive buffer (buffer distance: 2000 m),
Buffering the results of the first buffer process with an inner or negative polygon buffer (buffer
distance: -2000 m) - according to Haenel (2007),
Woodlands which are less than 4000 m apart from each other are connected via a potential
corridor created by the buffering procedure (figure 2).

2.3 Potential ecological corridors for open landscape areas of natural or semi-natural
vegetation
2.3.1 Methodology
Selection of all open landscape areas of natural vegetation types from the CORINE land cover
data set (table 3)
We included two mesohemerobe land use classes (231 and 243) because it may contain valuable
areas with specific species assemblage for example mountain meadows and open landscape of
complex structured fields and hedgerows.

distance: -2000 m) - according to Haenel (2007),
Open landscape areas which are less than 4000 m apart from each other are connected via a
potential corridor created by the buffering procedure (figure 4).

2.4. Designation of potential corridors of protected areas
2.4.1 Methodology
For the designation of potential corridors for protected areas the same methodology as for the
potential ecological corridors for woodlands and open landscape areas of natural or semi-natural
vegetation was applied (see sections 2.3 and 2.4).
Selection of all protected areas,
Buffering all protected areas with an outer or positive buffer (buffer distance: 2000 m),
Buffering the results of the first buffer process with an inner or negative polygon buffer (buffer
distance: -2000 m) - according to Haenel (2007),
Protected areas which are less than 4000 m apart from each other are connected via a potential
corridor created by the buffering procedure.

3 Gap analysis
3.1 Methodology for the gap analysis – identification and prioritisation of gaps
Often protected areas are too small to allow for the persistence of viable population of species.
Connecting networks of protected areas may increase species‟ persistence, therefore the need to
recover endangered species and rare habitat types has driven the demand for habitat connectivity.
One of the solutions is to maintain and restore habitats that will provide connections between
protected areas (Hilty et al. 2006). For that reason our gap analysis focuses on connecting
protected areas via potential habitat corridors and potential corridors of protected areas. Corridors
are understood as any space identifiable by species using it that facilitates the movement of animals
or plants over time between two or more patches of otherwise disjunct habitats (Lidicker 1999).
A gap analysis is a method to identify biodiversity (i.e. species, ecosystems and ecological
processes) not adequately conserved within a protected area network (understood in WP3 as
ecological network). Within the TransEcoNet project we define gaps as areas with high natural
value (oligotroph and selected mesohemerobe land use types) according to Dudley and Parish
(2006). The aim is to include valuable areas into the ecological network through the enlargement of
protected areas and the protection of stepping stones and therefore to improve the connectivity.
Because most of the relevant areas concerns less productive areas it should be easier to extensify
these areas and incorporate them into the ecological network as a crucial part for increasing the
connectivity.
The gap analysis is usually applied to fairly large areas, because this allows decisions about
conservation to be made with the best available information and on the basis of ecological rather
than political boundaries (Dudley & Parish 2006). Dudley and Parish (2006) define six key steps in a
protected area gap analysis (figure 7).
Report: Gaps in ecological networks
18
Figure 7: Key steps in a protected area gap analysis (Dudley and Parish 2006)
In our gap analysis we followed these key steps (figure 8), but we used easily accessible data on
ecosystems (CORINE land cover data set classified through a hemeroby index which we used as a
proxy for not available data on ecosystems respectively biodiversity for the WP3 search area) as
well as worldwide accessible species data (IUCN database). We combined a corridor/habitat
approach (identification of existing and potential habitat corridors) with a species number approach
(occurrence of threatened species – mammals, birds, reptiles and amphibians) for the prioritisation
process.
Identify focal biodiversity and set key targets (1)
Evaluate and map the occurrence and
status of biodiversity (2)
Analyse and map the occurrence and
status of protected areas (3)
Use the information to identify gaps (4)
Prioritise gaps to be filled (5)
Agree on a strategy
and take action (6)
Report: Gaps in ecological networks

Figure 8: Methodology of the gap analysis
In a first step we identified three different potential habitat corridors (wetlands, woodlands and open
landscape areas of natural and semi-natural vegetation) and potential corridors for protected areas.
The corridors were identified on an unspecified species approach using CORINE land cover data
considering different land use types (ecosystems). The potential corridor of mountainous habitats
was excluded from the further analysis because it does not represent a specific type of ecosystem
and it is almost congruent with the other corridors. For further information about the designation of
potential habitat corridors see chapter 2 (methodology for the designation of potential habitat
corridors). Thereafter the three possible ecological corridors and the potential corridor of protected
areas have been combined and labelled with attributes according to table 4.

Areas which are already within the ecological network of protected areas (attributes 111, 222, 333)
were excluded from the further analysis because we assume that these areas are already well
protected, managed and monitored closely to conserve biodiversity. Of course this might not be true
for all protected areas in the investigated area. But in this analysis we are looking for ecological
gaps (missing corridors between protected areas) rather than for management gaps. Figure 11
shows that depending on the region between 38 % (WP3 search area) and 67 % (Project Region
North) of the area of potential habitat corridors are already under protection.
For the determination of gaps all land use classes from the CORINE land cover data set with an
oligohemerobe hemeroby index (close to natural) and two selected land use classes with an
mesohemerobe hemeroby index (semi-natural) according to Steinhardt et al. (1999) where chosen
(table 5).

We included two mesohemerobe land use classes (231 and 243) because it concerns valuable
areas with specific species assemblage for example mountain meadows and open landscape of
complex structured fields and hedgerows.
After this selection procedure the determined possible gaps were combined with the available data of the occurrence of threatened species (IUCN 2009). Shape files and metadata can be downloaded under:

Thereafter according to the European Red List of amphibians (Temple and Cox 2009), reptiles (Cox
and Temple 2009), birds (BirdLife International 2010) and mammals (Temple and Terry 2007) the
designated gaps were prioritised. Only species with the threatened categories „critically‟,
„endangered‟ or „vulnerable‟ were considered (table 5). Figure 12 shows the distribution of these
threatened species (amphibians, reptiles, birds and mammals) in the WP3 search area and the
determination of three categories of species occurrences.

Table 6 shows the prioritisation process which is an important part of the gap analysis. In total five
different prioritisation classes were defined (very low priority, low priority, medium priority, high
priority and very high priority) according to the type of gap and the number of occurrences of
threatened species. The assessment is based on a simple additive method, which means the gap
with the highest rank (gap within the overlay of three corridors within the corridor of the ecological
network of protected areas) and the highest number of threatened species have the highest priority
(very high priority). Although the location of either inside or outside the potential corridor of
protected areas was of a higher importance than the number of overlaying corridors.

3.2 Results of the gap analysis
A limitation to the size of the gap was set by 10,000 m2. Single gaps below this threshold were
deleted to exclude sliver polygons from the further analysis.
Figure 13 shows the results of the gap analysis for the WP 3 search area and figures 14 to 16 show
the situation in each project region.

Figures 17, 18 and 19 show the distribution of gaps, their priorities and the associated type within the WP3 search area and the project regions.
As shown in figure 17, only between 12 % and 30 % of the WP3 search area and the four project
regions is considered as gaps (according to the definition of gaps in TransEcoNet page 17) therefore it is a great possibility to reach a considerable improvement of the connectivity of protected areas with little effort (enlargement of existing protected areas and protection of stepping stones).

As tables 8 and 9 show most of the gaps (around 95 % to 98 %) are less than 5 km² and in the WP3
search area the smaller gaps have a higher level of priority (figures 20 and 21). Normally, small
gaps as well as gaps with a high priority should be prioritised. The former could maybe be closed
with less effort whereas the latter are of high importance due to their location and the number of
existing endangered or valuable species. But the feasibility of linking the parts of the ecological
network highly depends on current land use, existing plans or political decisions. This can only be
analysed in detail by local experts within the project regions.

The result of the gap analysis is the definition, prioritisation and visualisation of gaps within the
existing and potential ecological network. This analysis should lead directly to the development of
one or more scenarios for the expansion of the protected area network (Dudley and Parish 2006).
Therefore, results together with management and measurement strategies should be
communicated to target groups (policy makers and to the public).
The linkage of already existing networks through the designated potential corridors of protected
areas by means of the extension of already protected areas is our first priority. Furthermore, the
existing protected areas should be preserved continually and their connectivity should be improved
further by establishing near-natural or protected corridors between insular areas. Suitable specific
actions and measures should be taken by nature conservation authorities to reach these aims and
to conserve biodiversity.

We defined three categories of gaps according to their distance to an existing protected area –
enlargement of protected areas (adjacent to existing protected areas), stepping stones (less than
5000 m) and satellites (above 5000 m). As you can see in figure 22 the results differ according to
the specific project region. Between 32 % and 70 % of the gaps are located directly adjacent to an
already existing protected area. Between 62 %and 29 % of the gaps are less than 5000 m away
from an existing protected area and only 6 % to 0.7 % are more than 5000 m away.

3.3 Tasks for the project partners within the respective project regions
For more detailed management strategies and measures the gap analysis will be further analysed
within each project region of TransEcoNet. The involved project partners should analyse the
designated gaps more closely according to their size (less than 5 km², 5 - 10 km², 10 - 20 km², 20 -
30 km² and above 30 km²), the relationship between size and prioritisation level, the location
(transboundary or unilateral gaps) and possible management strategies and tangible measures. To
include the transboundary aspect in the analysis of the four project regions the method applied to
the transboundary connectedness of protected areas should be used (see methodology of
transboundary connectedness). In addition to the designation of gaps this allows to classify if the
gaps are either unilateral or transboundary which can be used as an additional information for the
prioritisation of measures.

3.4 Results of the detailed gap analysis in the Project Regions
A detailed gap analysis was accomplished to analyse and characterise the gaps in the four project
regions.
3.4.1 Transboundary issues
Two different methods concerning transboundary issues were applied. The first method was a
segmentation of the borderline into three categories:
transboundary gap (on both sides of the borderline)
unilateral gap (on one side of the borderline)
no gap (no gap along the borderline)
The results differ depending on the project region (figs. 23, 25). Most transboundary gaps were
detected in the Project Region South with nearly 15 % compared to less than 5 % in the Central
Project Region South.

The second method applied was the identification of transboundary and unilateral gaps concerning
the gaps (polygons) itself. The same categories as in method one were used.

unilateral gap (polygons which are adjacent the borderline at any point)
no transboundary gap (polygons which do not cross the borderline)
Report: Gaps in ecological networks
38
If a gap adjoins a border and also crosses the borderline, the gap is characterised as transboundary
gap only. Only between 1 % and 6 % were identified as transboundary gaps and between 6 % and
15 % as unilateral gaps (figs. 24, 25).

3.4.2 Landcover type analysis
The type of landcover and the level of priorities was analysed in all project regions. Most of the gaps
are either woodland (59 % to 71 %) or open landscape areas (24 % to 40 %) (fig. 19). Only a very
small percentage (0,3 % to 5 %) are water gaps.
The distribution of levels of priority shows that except for the highest priority all levels are
represented in all project regions and landcover types (figs. 26-28). The highest priority only occurs
in the Central Project Region North for woodland and open landscape areas. Figure 29 shows a
map of the landcover type of the gaps in all project regions.

3.4.3 Correlation between gap size and the level of priority
The correlation between the size of the gaps and their level of priority reveals that in all project
regions the situation is that the smaller the gaps the higher the level of priority (fig. 30).
Figure 30: Correlation between gap size and the level of priority for all Project Regions
3.4.4 Connectivity analysis
The aim of the connectivity analysis was the investigation of the connectedness of each gap to the
nearest already existing protected area. This was done with the help of the nearest neighbour index.
Most of the gaps are either enlargements to already existing protected areas (36 % to 71 %) or
stepping stones in the vicinity of 5000 m of existing protected areas (29 % to 62 %) (figs. 24, 31 and
32). Only a few gaps are satellites which means that they are more than 5000 m away from any
existing protected area (0.5 % to 4 %) (fig. 33).
The gaps adjacent to already existing protected areas are characterised by a higher level of priority
than stepping stones whereas stepping stones show a higher level of priority than satellites (fig. 31-
34).

3.4.5 Analysis and description of hotspots
The gaps with priority level 1 and 2 (highest and high priority) were defined as hot spots. Only in the
Central Project Region North gaps with the highest priority level (1) occur. In all other project
regions there are only gaps with priority level high (2) which are defined as hot spots. The Project
Region North has the lowest percentage of hot spot areas with only 4 % where as the Project
Region Central South reaches nearly 20 % (fig. 18). The largest area of hot spots is located in the
Project Region Central North with nearly 235 skm (fig. 35).

The characteristics of this transboundary gap (figures 40 and 41) are: transboundary across the Polish-Czech border, woodland area, size 20 to 30 skm, stepping stone (less than 5000 m away from the next protected area) and enlargements to already existing protected areas.
3.4.7 European, national and regional planning of biotope corridors (interlinked systems of biotopes)
and the correlation with the gaps identified by TransEcoNet
For the correlation of gaps identified by TransEcoNet with the plans for biotope corridors the gaps
were overlaid with existing network plans (European, national and regional).
The following datasets were used:
European biotope corridors: EECONET
National biotope corridors: TSES - Czech Republic
EECONET - Czech Republic
ECONET - Poland
TSES - Slovakia
Habitatnetzwerk - Austria
Nemzeti Ökologiai Halozat (NOH) - Hungary
Regional biotope corridors: search area for biotope corridors in Saxony
For Slovenia no network plans were considered, because the important ecological areas of Slovenia
were already included within the network of protected areas.
We defined four categories:
TransEcoNet gaps corresponding with European, national and regional network plans
TransEcoNet gaps not corresponding with European, national and regional network plans
(only TransEcoNet gaps localised)
Corridors only identified by European, national and regional network plans (no TransEcoNet
gaps defined)
Network of protected areas
The correlations are displayed for each project region in figures 42-45 followed by a statistical
analysis (fig. 46).

The overlay of gaps identified by TransEcoNet with European, national and regional network plans
is different in every project region because of various statuses of existing networks plans (fig. 46).
For example no network plans exist in Slovenia whereas two different network plans are available
for the Czech Republic (EECONECT and TSES). The least corresponding TransEcoNet gaps with
network plans are situated in the Southern Project Region, only 2.4 %, because of no network plans
for Slovenia and this region of Austria. In all other Project Regions the percentage of gaps which
corresponded with network plans is between 10.5 and 12.6 %.
3.5 Combination of the results of the transnational ecological network initiative analysis
(output activity 3.2) and the gap analysis (output activity 3.3)
The results of the transnational network initiative analysis (activity 3.2) and the results of the gap
analysis (activity 3.3) were combined to create maps (figures 47 and 48) which illustrate the
overlays. Most initiatives are located in the Alps, the Carpathians and around the lake Neusiedl.

3.6 Possible management strategies, existing implementations (best practise examples)
and subsidies
3.6.1 Management strategies
Before one is able to define specific management strategies the clear designation of protected
areas, buffer zones and ecological corridors is necessary. The focus should be more on maintaining
and enhancing the functional connectivity rather than the structural connectedness (Taylor et. al
2006) and improving the size and quality of core habitats and stepping stones (Kettunen et al.
2007). Overall management strategies for the gaps are the conservation, management and creation
of enlargements or new protected areas. Unfortunately this is not possible in most of the cases
therefore the elimination or prohibition of intensification of land use should be one of the foremost
strategies to conserve areas with high natural value currently not adequately protected within the
network of protected areas and protect them from deterioration. Other important strategies are:
Implementation of necessary measures to prevent deterioration of high nature value areas
Extensification of land use (pastures, meadows and agriculture);
Landscape conservation and preservation of an open landscape with animals (e.g. sheep,
goats and cows);
Managed mowing of pastures, meadows and roadside verges;
Report: Gaps in ecological networks
60
Species-rich seeding on agricultural fields to provide a source of food and cover for wild
fauna;
Promotion of organic farming, extensive agriculture and the reduction or targeted use of fertiliser, pesticides and herbicides in agriculture;
Maintaining and creating of agricultural field margins;
Creation of forest reserves and the conservation of riparian and other natural forests;
Forests conversion to natural woodlands regarding to their location;
Use of indigenous seeds and plants;
Maintenance and creation of old-growth and deadwood islands and the conservation of specific individual trees (nest and hollow trees, trees with rotten sections or fungal infections, or bizarre trees);
Preservation and reintroduction of traditional farming methods (e.g. sheep grazing);
Preservation and establishment of structurally rich forest edges;
Preservation, maintenance and replanting of landscape structures such as hedges, tree
rows, small woodlands, individual trees, dry stone walls, rock fragment piles, mixed
orchards, and wetlands;
Use of existing infrastructure and avoidance of the extension and new construction of
fragmenting elements;
Encouragement of unpaved paths, as they mostly have a lower barrier effect;
Green bridges/wildlife crossings and underpasses for small animals;
Creation of riparian strips and woodlands;
Maintenance and restoration of rivers, lakes and wetlands;
Creation of fish passes and other fish migration aids;
Controlling invasive species and creation of quiet zones for species (e.g. breeding zones);
Consideration of central elements of ecological networks in spatial planning;
Raising awareness and involving local stakeholders,
Informing local stakeholders about possible subsidy programs;
Monitoring of measurements and the control of efficiency of measures.
The list of management strategies (Kohler and Heinrichs 2009) is based on the detailed list of
management strategies for ecological networks in the Alps developed within the projects
ECONNECT, (www.econnectproject.eu), ALPARC (Alpine Network of Protected Areas,
www.alparc.org), ISCAR (International Scientific Committee on Research in the Alps, www.iscar-
alpineresearch.org), the European Alpine Programme of the World Wide Fund for Nature
(http://wwf.panda.org/what_we_do/where_we_work/alps) and CIPRA (Commission Internationale
pour la Protection des Alpes, www.cipra.org). A comprehensive description (factsheets) of these
management strategies is available for download under www.alpine-ecological-network.org.
Involving all key stakeholders from an early stage (White et al. 2005) as well as coordinating the
management strategies across borders should be an important goal. In the Project Region North a
first meeting with responsible authorities (Saxon State Ministry of the Environment and Agriculture,
Saxon State Office for Environment, Agriculture and Geology, Czech Agency for Nature
Conservation and Landscape Protection, Czech Ministry of Agriculture) was held in June 2010. The
main focus of the meeting was the discussion of how to apply and implement the outputs of WP3
within national and regional planning strategies. The attendees of the meeting acknowledged the
Report: Gaps in ecological networks
61
results of WP3 and discussed further strategies for the closer investigation of the gaps within WP5.
Another meeting is planned for early September 2010 to discuss further strategies for raising the
awareness and planning strategies for poorly connected protected areas in the Northern Project
Region. People involved should be local planning authorities as well as nature conservation
organisations.
Further meetings with responsible authorities to communicate the results of WP3 within the other
project regions should be organised by the involved Project Partners.
Because of the use of a common and comparable database European and national datasets (large
scale datasets) were used for the analyses within WP3. Therefore the results of the gap analysis
only give an overview of possible locations of gaps. These gaps have to be further investigated and
distinguished with the help of local biodiversity data (possible in WP5) before specific local
management strategies can be applied for improving the connectivity of the network of protected
areas.
3.6.2 Known existing implementations
Examples for new protected areas and the alteration of protection statues are illustrated in figure 49
to 53.
In the Czech Republic some new protected areas are planned for example: the new NP
Krivoklatsko (from the central part of the protected landscape area Krivoklatsko), enlargement of
protected landscape area Kokorinsko, establisment of new protected landscape areas Doupovske
hory (close to Karlsbad) and Soutok (at the trilateral border point CZ-SK-AT). Some small areas are
proposed as well, maybe with higher probability of success: national nature reserve Rolavska
rasliniste (incl. Gross und Klein Kranichsee on the border with Saxony), national nature monument
Jestrebske slatiny (south-east from Ceska Lipa) and some others. In the area of the Bohemian
Switzerland plans for including parts of the protected landscape areas into the national park exists
(figures 52 and 53). The recently established national natural reserve - Elbe Valley is illustrated in
map 53.
The area of the Lake Neusiedl is planned to be upgraded to a biosphere reserve and the Natura
2000 area Parndorfer Platte should be enlarged.
Other plans which could not be visualised by now include the new Natura 2000 site designated in
the upper part of River Mura near Gornja Radgona (Slovenia) where the river is located at the
border to Austria. The area will be designated for both EU directives, Council Directive 92/43/EEC
(21 May 1992 on the conservation of natural habitats and of wild fauna and flora) and Council
Directive 79/409/EEC (2 April 1979 on the conservation of wild birds). The river is already protected
by Natura 2000 on the Austrian side of the border.
A lot of new protected areas and alteration of protection statues can be found in Hungary.
The maps in figure 49 show an overview of new protected areas or areas of altered protection
status in the project regions. Figures 50-55 show details for the Northern Project Region, the
Central Project Region South and the Southern Project Region.

The Czech Republic is the only Country in our study area which implements the concept of
ecological networks (TSES). The Territorial System of Ecological Stability (TSES) started in the
80ties and is implemented through the creation of bio-centres, bio-corridors and intersecting
elements of different levels (local, regional and supra-regional). Beside the three levels of TSES
there is also a provincional/biospherical level or rather significance. This type of TSES has core
areas larger than 10 000 ha and only several bilateral regions in the Czech Republic fulfil this
criteria: the provisional significance can be assigned to the Dyje valley in the National Park Podyji
and to the reservation Prameny Úpy in the National Park Krkonoše. The biospehrical significance
can be assigned to the National Nature Reserve Modravské slatě together with the core area in the
Bavarian National Park.
For the implementation of the TSES both national and private funding is used. The national fund
resources include landscape care programme, funds for complex land consolidation, programme of
revitalisation of river network or Rural Development Programme. Since 2007 also programmes from
the EU can be used - in this case it is Operational Programme Environment. The implementation is
realised in the local communities in close cooperation with the local stakeholders.
The implementation rate differs widely around the Czech Republic. Unfortunately no statistic is
available to show how much of the corridors and bio-centres have been implemented. A study from
2005 which mapped implementation of the TSES funded by Landscape care Programme within
regions during 1997-2004 (Lacina 2005, 2008) reveals that the majority of the elements were
implemented in Moravia and also in the eastern and southern Bohemia on both local and regional
level. Examples are: regional bio-centre in Vodňany (southern Bohemia), supra-regional bio-corridor
in Ostrov u Lanškrouna (eastern Bohemia) and the regional bio-centre in Tvarožná (southern
Moravia).
Unfortunately the implementation is not always successful in terms of fulfilling the ecological
functions the networks were designed for.
Slovakia also has the planning for TSES but did not implement any measures so far.
Every country designs and implements their own network system mostly without considering
neighbouring countries. For the realisation of transboundary networks the responsibilities have to be
on an European level for example with an ecological networks framework directive according to the
European water framework directive. As long as no plans for ecological networks on European level
exist, the connection and management of corridors across borders is not more than a vision.
3.6.3 Subsidies
The countries involved have different grant programs to support the extensification of land use and
support nature conservation. For example the financial instruments supporting nature conservation
and landscape protection in the Czech Republic (Tab. 10).

management and can be divided into three sub-programmes:
a. sub-programme for implementation of measures resulting from management plans of special protected areas and their buffer zones, and for NATURA 2000 sites (PPK - Protected Areas)
b. sub-programme for improvement of preserved natural and cultural heritage (PPK - free landscape)
c. sub-programme for securing care for vulnerable and handicapped animals (PPK - Handicaps)
LIFE + supports projects focusing on nature conservation and landscape protection in the EU; it is open for the period 2007-2013.
Support of rehabilitation of natural landscape functions. This programme supports investment and non-investment projects that perform adaptation measures mitigating the impacts of climate change on water, forest and non-forest ecosystems. It enables Agency for Nature Conservation and Landscape Protection of the Czech Republic as well as administrations of national parks to carry out actions arising from management plans for special protected areas, recommended actions for bird areas, rescue programmes and management programmes for specially protected species of flora and fauna. It is also used to finance monitoring and supporting materials. There are several sub-programmes ranging from provision of obligations of nature protection authorities in relation to special protected areas through adaptation measures to mitigate climate change impacts on ecosystems to securing background materials for improving natural environment and for landscape monitoring programmes.
Regional operational programmes for NUTS II regions focus on enhancement of life conditions in settlements and rural areas especially through better educational, social and healthcare infrastructure as well as through the improving of the environment.
Sub-programme Management of state property in specially protected areas includes processing of management plans as well as forest management plans for special protected areas and their buffer zones, maintenance of technical objects serving for protection purposes, measures designed to eliminate past negative actions or adverse effects in the protected areas and measures ensuring the existence of localities for which the protected areas were declared.
Operational program Fisheries for the period 2007-2013 contributes to the nature conservation and landscape protection mainly with axis 2 Aquaculture that tries to maintain fish production with the environmentally friendly means and to enhance conditions for fish breeding and water quality.
Contributions to the forest management are dedicated e.g. to restoration of forests damaged by pollutions, ecological and environmentally friendly technologies, support to reduce damage caused by pests etc.
Operational programme Prague – Competitiveness supports among others projects

enhancing environment (priority axis 2). the public interest, especially flood prevention, removal of flood damage and reconstruction of ponds. They also support non-productive functions of ponds.
Rural development programme contributes to the improving of the rural areas of the Czech Republic. It is based on the sustainable development, enhancement of the environment and reduction of negative influence of the intensive agriculture. Measures relevant for nature conservation and landscape protection are included in axes II (improvement of environment and landscape) and III (life quality in rural areas and diversification of rural economy).
Rehabilitation of areas affected by floods in 2009 was declared within the programme Revitalization of river systems. It includes restoration of natural functions of water courses, biodiversity restoration, renewal of sewage treatment plants damaged by flash floods, restoring ecological stability and water retention capacity of the landscape, removing the effects of soil contamination and stabilization and geological survey of land and rock slides.
Agro-environmental programmes belong to the programmes of Ministry of Agriculture and are dedicated to protection and restoration of the environment in agricultural areas. The main goals are to avoid accelerated water runoff, reduce soil erosion, promote ecological stability of the landscape and preserve and enhance natural diversity of the agricultural land. The goals are implemented through several measures, such as extensification of production on arable land, reduction of artificial inputs (pesticides, fertilizers), introduction of organic and integrated farming systems, maintenance of abandoned agricultural or forest land, access for the public to agricultural land etc.
Apart from these programmes that are financed directly by ministries or regional authorities, there
are also programmes that are financed/co-financed by the State fund of the environment of the
Czech Republic. For the year 2010 following programmes were declared:
Programme to promote purchasing of the land in special protected areas, their protection
zones and significant landscape elements – the aim is to ensure effective protection of nature in
the most valuable areas through the ownership of professional bodies.
Programme to support municipalities located in the areas of national parks – the aim is to
compensate for losses of the restricted economic development of the municipalities. The supported
areas include environmental education, maintenance and construction of visitor infrastructure,
removal of illegal waste dumps, revitalization of residential green, waste water treatment, promotion
of energy self-sufficiency and co-financing of selected projects from Operational programme
Environment.
Programme to support water monitoring – is intended to support the development of methods for
monitoring water status and detection of water status in monitored profiles, including collection and
transportation of samples.
Programme to support non-productive plant species diversity and conservation of genetic
resources – the aim is to enhance the diversity of residential and landscape green with the
emphasis on preservation of unique genetic material of indigenous endangered and culturally

significant non-productive plants and to increase public awareness about the importance of this
issue.
Programme to support municipalities in which territory a state of emergency was declared
due to floods – the goal is to renew water infrastructure and its proper functions.
Environmental contracting are implemented in Austria and Germany (Vertragsnaturschutz) and Agri-Environmental Programmes are implemented in Austria (ÖPUL), Slovenia (Kmetijsko Okoljski Program) and Germany / Saxony (umweltgerechte Landwirtschaft). Saxony also provides subsidies for the conversion of forests. LIFE also founds projects in Austria (Great Bustard) and in Slovenia.
