Chapter Three Description of Environment species in both the farm land and fallow areas dominated the avifauna of the Oben Field area. The bird species recorded by sighting, nest observations and call sounds include the white egrets, kites, weaverbirds, owls and hawks. Different species of reptiles and amphibians were also noticed. Prominent among these were Agama agama (common lizard), gecko, frogs and snakes.

Chapter Three Description of Environment 3.2.7 Soil Microbiological Studies The soil microborganisms contribute to the recycling of nutrients and energy within the ecosystem and hence the microbiological evaluation of the soil in the present investigations. Rainy season microbial counts were higher than dry season levels suggestive of the apparently higher organic load during the rainy season than during the dry season. The microorganisms under study were bacteria and fungi. The heterotrophic bacterial counts Table 3.10a and 3.10c varied from 1.4 x 10 8 - 2.6 x 10 10 cfu/g soil during the wet season and from 2.5 x 10 7 – 2.2 x 10 8 cfu/g soil during the dry season. The bacterial population was dominated by Bacillus sp, Mocrococcus sp, Klebsiella sp, Staphylococcus sp, Proteus sp and Escherichia coli. The proportion of hydrocarbon utilizers which were mainly Bacillus and Pseudomonas species were low and they varied from nil to 1.74% during the wet season and nil to 5.0% during the dry season. The fungal counts (Tables 3.10b and 3.10d) were lower than the bacterial counts and varied from 4.8 x 10 5 to 3.5 x 10 6 -propagules/g soils during the wet season and from 2.5 x 10 5 to 8.2 x 10 6 propagules/100g soil in the dry season. The predominant fungal isolates were Mucor sp, Penicillium sp, Aspergillus sp and Cladosporun sp. Some of the Penicillium and Mucor species isolated from the study area were petroleum degraders.
