Status of Indigenous Tree Species in Girei Forest Reserve of Adamawa State

Abstract

Quantitative assessment of indigenous tree species was carried out in Girei Forest Reserve. To achieve the objectives, five plots of 50m x 50m in size were randomly laid in the reserve and number of trees in each plot was enumerated. The highest frequency of 26.7% was observed in the second plots, while the fourth plot exhibit a lower frequency of 15.0%. The result also revealed that almost 53.3% of the tree species in the reserve are being endangered (tree with frequency less than 5). It was observed that most of the indigenous trees are rare in the area and this could be as a result of the following agents such as bush burning, animal grazers, farmers and saw millers. The results of Shannon and Evenness Indices indicated the high uncertainty and rareness of the indigenous species in the study area. Also, Analysis of variance result revealed that there was no significant relationship among the sampled plot (p > 0.05). At this point of endangerment of the indigenous tree species, there is therefore a need for conservation strategies for future use of these indigenous trees and to reduce the effect of global warming on the earth surface.
