It was investigated the effects of illegal anthropogenic </em><em>activities on the plant community structure on the western part of </em><em>Rungwe mountain forest reserve.</em> <em>The study area was classified into three levels of disturbance (least disturbed, moderately disturbed and highly disturbed) and transect method was used to collect data. Two clusters (clusters A and B) of plant communities </em><em>based on</em><em> Two Way Indicator Species Analysis (TWINSPAN) were found. Cluster A included communities from the least and moderate disturbed sites and cluster B had plant communities from the highly disturbed site.</em><em> The least, moderately and highly disturbed sites had many individuals within the DBH range of 19-57 cm, </em><em>10-47 cm and 11-14 cm, respectively. The observed variation in size class structure among the sites was caused by the intensity of anthropogenic disturbance. The </em><em>inverted J shaped patterns </em><em>of </em><em>diameter size class distribution were indicative of regeneration and</em><em> active recruitment from lower tree growth sizes.</em> <em>It was concluded that the existing plant</em> <em>community structure was shaped</em><em> by the impacts of </em><em>anthropogenic activities. </em><em>Thus, conservation management interventions are necessary for protection of the forest. </em></p><div>&nbsp;</div> ER -
