Small scale spatial and temporal variation in vegetation structure and composition of tropical forests under different management systems within Mount Kenya ecosystem

Fundi Peter

This study examined spatial and temporal variation in forest structure and composition of two indigenous Mount Kenya forests under state and private management by quantifying variations between seasons and in space at a small scale. To demonstrate spatial variation, slight change in altitude affected trees and shrub diversity at Mawingu. Change in slope, however affected herbaceous plants diversity in both sites during the dry season. On examining temporal variation in vegetation composition, herbs diversity was higher at Mawingu (H’=1.60) than at the conservancy ((H’ =1.40) during wet season. Generally, Jaccard coefficient of community similarity depicted a low vegetation similarity between the two sites in both wet (CC=33%) and dry (CC=35%). The observed variation in vegetation composition could have been caused by changes in abiotic factors, such as elevation, slope position, water table and edaphic aspects. Additionally, biotic factors including human influence and herbivory could contributed to the variance.
