Species Specific Factors
When dealing with a specific species the objective is to provide the most suitable habitat. A high abundance of Cheetahs is correlated with large amounts of open rangeland, high density of prey species and absence of natural predators such as lions, leopards and hyenas.
5. Ecosystem
Open grassland and Savannah are the type of ecosystem that the cheetah can
be found in. There fore all other vegetation type was excluded from the vegetation
layer. Cheetahs prey mostly on small grazers such as impala and gazelle. These
ecosystems provide both prey species and the open areas that are needed for
the cheetah to be an effective hunter.
6. Elevation
Cheetahs are only found on relatively flat land. This excludes higher elevations.
The elevation value that was suitable was set to 1500 m, this may seem high
but the majority of Kenya is quite elevated.
7. Rainfall
Rainfall plays a key role in the suitability of a habitat. For every ecosystem
there can be large ranges in rainfall. The rainfall factor was set so that
all areas that would be on the dry end of the spectrum would be excluded from
the habitat suitability. Since the prey species of the Cheetah are grazers
areas with the greatest amount of vegetation, thus the largest density of
prey species.
The combination of these factors provides the information needed to perform the analysis. However, not each factor is weighted equally. Once the layers have been developed into fuzzy layers they are then weighted based on potential impact on the conservation area. This is performed by using the MCEWLC (multi-criteria evaluation weighted linear combination). This provides two layers that were differentiated by the proximity to current parks (close and away). Further analysis of the selected area shape was calculated to narrow down the potential sites.
