Statement

South facing slopes represent important climate change refuges. These areas are likely to serve as refuge habitats during period of temperature increase and moisture decrease as they naturally have lower temperatures and higher moisture levels that the general

landscape.


The 90m resolution SRTM Digital Elevation Model was used as the basis for the assessment. This layer was processed in IDRISI according to the following method:

? Areas with a south facing aspect were identified using IDRISI modeling tools (aspect of between 110° and 250°).

? Areas of a slope of 10° or greater were identified using IDRISI modeling tools.

? These two layers were intersected to identify areas with steep south facing slopes.

? Small areas were removed (>100ha).

A 30% target for these rivers was set for the first CBA run, while the remaining unselected areas were included as Ecological Support Areas if they were not transformed.
