Abstract

The objective of this study was to assess the stability of open grown forest trees in Nnamdi Azikiwe University, Awka, Nigeria, for sustainable management. The stability of a tree is very important for understanding the structural firmness of a tree. Tree stability can be assessed using tree slenderness coefficient (TSC) and crown ratio (CR). The study area lies between latitude 6.245o and 6.283oN and longitude 7.115o and 7.1219oE in the Tropics. Total enumeration of open grown tree species with D &
