Abstract:
The study was carried out to assess the diversity and fodder values of native tree and shrub species in the traditional silvopastoral system of Adamawa, State, Nigeria. Transects of 1100m in length with a distance of 500m between them were used in the study site. Sample plots of 25m x 25m in dimension were laid in alternate positions along each transect at 250m interval. All the trees/shrub encountered in each of the sample plots were identified by their botanical names and species with potential for fodder were classified based on farmer’s citation on palatability to Ruminant Livestock. Biodiversity indices were estimated using appropriate formula. The results of floristic diversity showed that the two sites were rich in tree and shrub species diversity. This was supported by the value obtained for Shannon-Weinner diversity indices (3.00, 2.70), Marlalef index of species richness (6.51, 4.58), Species evenness (0.40, 0.32), Simpson’s index (0.86, 0.96) and Minhinck’s index (1.16, 0.57) in Nyibango and Gongoshi forest grazing reserves respectively. Fifty four percent (54%) of the species were classified as shrubs, while forty six percent (46%) were trees based on their growth characteristics. The species were rated according to their fodder value as high (19%), medium (34%) and low (27%) based on farmer’s perception of palatability to ruminant livestock. A relatively small percentage (19%) was rated to be of no fodder value. The study revealed that native tree and shrub species contribute substantially to availability of feed for livestock in the traditional silvopastoral system of Adamawa State.
