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 />
