Examination of stand compositionandstructureof amboi forest reserveintarabastate, nigeria.

The study examined the stand composition and structure of Amboi Forest Reserve in Taraba State, Nigeria.Sixty eight (68) hectare plots were demarcated out in the forest. Each hectare plot was re-demarcated into four (4) equal sizes of 50m x 50m (2,500m ) out of which one was randomly selected for the assessment. The enumeration covers all individual tree species from > 5cm diameter. Data collected were the lists of the tree species, diameter at breastheight (dbh) and total heights.Halga altimeter and diametertape were used for the measurements of the trees total heights and diameter at breast heights (dbh). The result indicates that the forest was composed with 111 trees species belonging to32 taxonomic families. The family of Caesalpiniaceaehad the highestnumber of trees sampled, followed by Moraceae .Cola digitata in the family of Sterculiaceaewas the most abundant individual tree species in the forest, followed by Myrianthusarboreus in the family of Moraceae. The diameter class from 20cm - 29 cm and height class of 10m-19m had the highest number of trees. The structure of the forest showed that majority of the tree species were in Co-dominant, followed by the Intermediate.The distribution of the trees in diameter and total heights in the forest indicates there are no maximum volumes of produce required annually as a result of over-exploitation. Enrichment planting is recommended in order to sustain the forest.
