1.1.2 HABITATS<br />
1.1.2.1 OVERVIEW:<br />
As seen in Section 1.1 on the general treatment <strong>of</strong> biodiversity, the large variety <strong>of</strong><br />
ecosystems also indicates a high variety <strong>of</strong> habitats. Each habitat is characterized by those<br />
conditions which favor the presence <strong>of</strong> specific types <strong>of</strong> organisms. Several factors that affect<br />
ecosystem existence affect habitats and their species. Biodiversity managers in Cameroon are<br />
concerned with habitat management that should lead to ecological stability and prevent<br />
species decline.<br />
Studies in Cameroon’s biodiversity have shown that habitat classification is subjective<br />
and depends on the investigator’s objectives. In most cases, classifications will depend on the<br />
terrestrial, aquatic and soils types. One site can serve as habitat for several species. Thus<br />
plants and animals can benefit from the same habitat given their complementary roles in the<br />
ecosystem. Of the 26 resident bird species in Bali-Ngemba, Cheek et al (2004), recorded 22<br />
different micro-habitats, see Table 4 below.<br />
. The African elephant Loxodonta africana africana (4000-6000 kg) has adapted itself to<br />
the savannah habitat while the Loxodonta africana cyclotis (2500-3000 kg) is used to the<br />
forest habitat. A plant genus, Lophira has adapted itself in the Tropical Rain <strong>Forest</strong> as<br />
Lophira alata and in the Savannah environment as L. lanceolata. From the analysis <strong>of</strong> the<br />
vegetation <strong>of</strong> the Bamenda highlands, Hawkins and Brunt (1965), it is concluded that<br />
grassland and savannah species migrated from lower altitudes.Consideration on the habitat<br />
examination will be treated under: Habitat types, changes in habitat quality, habitat loss and<br />
habitat recovery.<br />
1.1.2.2. HABITAT TYPES:<br />
According to the NBSAP (2002), habitat types have been classified into four main<br />
categories: Aquatic, <strong>Forest</strong>s Savannah, Montane and soil habitats. See table 3 below.<br />
