2.3 – Sensitivity based on species richness

The sensitivity ranking system for species richness incorporates data on large mammals and crocodiles, birds, plants and fish species. The species richness value of a specific site was calculated by dividing the sum of species ranking values in a specific area by the frequency of occurrence of the species. Whereas areas where all variables were represented were divided by four (4), areas with only data on two variables (e.g. fish and birds) were divided by two. The results of this analysis are presented in the species richness map below.

Highlights of the species richness map

Forests, both national parks and forest reserves, generally show higher species richness than the grassland/woodland areas (Figure 2.12). Parts of Budongo and Bugoma Forest Reserves, and Kibale National Park showed the highest species richness. The delta area of MurchisonFalls National Park also showed high biodiversity.
