Composition of Tree Species in Onigambari Forest Reserve, Oyo State, Nigeria
The tree composition of Onigambari Forest Reserve in Oyo State was
evaluated by laying out a plot size of 50 x 50/m2 resulting to four
plots per hectare. 104 and 93 stems per hectare were recorded. A total
of 197 tree stands were encountered in the two compartments studied
with family Sterculiaceae with species Cola gigantean, Cola millenii ,
Sterculia africana , Sterculia oblonga , Sterculia tragacantha ,
Triplochiton scleroxylon , Pterogota macrocarpa and Nesogordonia
papaverifera .as the most abundant having 34 stands, followed by the
family Papilionoideae with species Baphia nitida with 20 stands as the
most abundance species. About thirty-nine percent of the tree species
encountered were wildlings having a diameter at breast height of
64 10 cm. Less than one percent (0.50%) of the trees were of
merchantable size. This could be a thing of concern and it calls for
adequate resourceful and sustainable management techniques. Habits in
Onigambari Forest Reserve are presented in Table 1. A total of
forty-three (43) species of trees distributed into twenty (20) families
were encountered. Family Sterculiaceae and Fabaceae was the richest
with eight (8) species each followed by family Euphobiaceae with (5)
tree species. Based on their habit, these species were classified into
100% trees. Furthermore, it is of the importance that the forest
reserves be protected from illegal/indiscriminate logging among other
anthropogenic activities in order to allow it regenerate
