Identity and Diversity of Woody species in Some Communities of Kebbi State, Nigeria.

Kebbi state is known for its rich agricultural landscape, beautiful savannah woodland and shelter belts but it is gradually turning into a desert due to destructive human activities. The hitherto bushy savannah that dotted the landscapes of Kebbi and environs have been combed by fuel wood vendors exposing the state to the vagaries of environmental degradation, particularly that of desertification. A study was carried out to identify and evaluate the composition of woody species and diversity of savannah woodlands in four Communities of Kebbi State with the view of devising means of conservation and sustainable use of biodiversity. Random sampling technique was employed for the study. Four (4) quadrants measuring 50 m x 50 m (2500 sq m) were assessed from the manifold location to nearby settlements. The plant species sampled included all the saplings, shrubs and trees present in the study areas. The plant species were recorded per sampling quadrant and all species encountered were identified and listed. A total of 869 individual woody species belonging to 23 families, 17 genera and 37 species were enumerated. Gueira senegalensis recorded the highest total importance value (281.88), while Diospyros mespiliformis (2.49) had the lowest IVI in the four communities. The high IVI of G. senegalensis indicated its dominance and ecological success, its good power of regeneration and greater ecological amplitude. The Simpson’s index of woody plant diversity for the communities was 0.769. The value was high indicating a low complex community.
