Categories
Identification of Strategic Alpine Connectivity Areas (SACA)
4SACA Mapping
The structuring of the Alpine
and EUSALP territory in three
classes of Strategic Alpine
Connectivity Areas (SACA) will
offer the possibility to better
target actions for ecological
connectivity in these areas
and increase the impact of
these actions.

CSI – Continuum Suitability Index
5SACA Mapping
CSI = (2 x POP + 2 x LAN + 1 x ENV + 1 x TOP + 1 x FRA) / 7
5 Indicators
Altitude and Topography
Population
Land use
Environmental protection
Fragmentation
Basis of SACA’s Mapping
ALPBIONET2030
Preliminary remark
6SACA Mapping
Two types of different SACA categories cannot overlap
The map of the SACA will be realized at Alpine scale
Further zooming in the area will require a more detailed analysis
ALPBIONET2030
Categories
1 – Ecological Conservation Areas (ECA)
7SACA Mapping
= SACA 1
Favorable situation for ecological connectivity
Mainly need conservation of the favorable status
Well targeted large scale conservation policy
ALPBIONET2030
SACA 1 - Ecological Conservation Areas
8SACA Mapping
Method
Basis : CSI
Nearest neighbor (1km) to smooth CSI
Selection of all areas with a CSI value >= 80
(Minimum size of areas is 100 ha)
ALPBIONET2030
SACA 1 - Ecological Conservation Areas
9SACA Mapping
EUSALP :
95% SACA 1 in protected areas
13% of protected areas
Alpine Convention :
80% SACA 1 in
protected areas
70% of protected
areas
ALPBIONET2030
Categories
3 – Connectivity Restoration Areas (CRA)
10SACA Mapping
= SACA 3
Highly fragmented, most ecological links interrupted
Numerous competing land uses
High investment necessary to improve situation
Ad-hoc measures to improve connectivity (punctuated approach)
Strategic large scale projects
ALPBIONET2030
SACA 3 - Connectivity Restoration Areas
11SACA Mapping
Method
Basis : CSI
Selection of all areas with a CSI value <= 50
ALPBIONET2030
SACA 3 - Connectivity Restoration Areas
12SACA Mapping
ALPBIONET2030
Categories
2 – Ecological Intervention Areas (EIA)
13SACA Mapping
= SACA 2
High potential for ecological connectivity
High impact with relatively low investment
Highlighting the most favorable spots for interventions
Development of a adapted spatial planning policy
+ single well placed actions (wildlife passages, etc)

Method
“ resistance to movement in a landscape is analog to resistance in
an electric power circuit ”
ALPBIONET2030
SACA 2 - Ecological Intervention Areas
15SACA Mapping
Method
Basis : SACA 1 results and CSI as resistance matrix
We use Electrical circuits theory on EUSALP
We get a gradient of current between the SACA 1 (the
whole territory will be covered)
Current flows from SACA 1 and moves according to the resistance
