| Preliminary survey of the wildlife biodiversity of the Hadejia Nguru Wetlands | |
| 2015 Dutse Journal of Pure and Applied Sciences (1 ): 1-4 | |
The wetlands are among the world's most productive environments. The wetland provides water and primary productivity upon which many species of plants and animals depend for survival. The wetland supports high concentrations of birds, mammals, reptiles, amphibians, fish and invertebrates. The wetland is critical to the maintenance of ecosystems through such processes as nutrient flushing, effects on microclimates and water holding capacity. The Hadejia-Nguru wetlands lie within the semi-arid region of Nigeria. The topography of the area is mostly low laying flat surfaces on the north-eastern side and limited local relief in the southern and western parts. The objective of the survey is to establish prevailing and existing trends in wildlife composition and population. Methods such as road count, road kill, sample census, interview and other signs were used to determine the diversity and population of the wildlife. Results showed a total of 40 species of wildlife consisting of 25 species of terrestrial mammals and 15 species of reptiles. The wildlife composition of the NHW shows a gradual species reduction. Further research was ecommended to evaluate in more quantitative terms the actual diversity, causes of biodiversity loss and the changes in the ecosystem_._ |
