10 TERRESTRIAL FAUNA
10.1 Theoretical Considerations
The statements made in the Chapter on Vegetation on biodiversity aspects in dam
projects are largely valid for the terrestrial fauna as well, since animals largely depend
on their habitats.
One specific issue that often needs to be considered is the potential impact of a project
on migrating species (especially birds). This is insofar of importance that a specific site
- as is the case for many wetlands - can be of high importance for the survival of animal
populations and species even if they do not live there permanently, but use this area
only at specific times of the year, e.g. as resting and feeding places during migrations or
as overwintering areas.
In the framework of an EIA, it is never possible to study all the animal groups living in
the study area. The efforts have to concentrate on groups of animals which can more or
less readily be identified and whose habitat requirements are known well enough, and
which can therefore serve as indicator organisms for the state of their habitats. As for
plant species, the emphasis lies on either economically important species (food or other
uses, pests) and on rare, endangered and/or endemic species. The most important groups
in this sense are mammals and birds, and reptiles and amphibians. For the entire aquatic
fauna, fish serve as indicator organisms.
10.2 Prevailing Situation
10.2.1 Mammals
In total there are 193 mammals in Liberia (Groombridge and Jenkins, 1994); the
following 31 species can be found in the Red List of IUCN. 9 species are listed as
endangered, 12 as vulnerable and 10 as near threatened.
