    Abstract

    The distribution of Pandans was assessed by laying down 20m x 20m quadrates at four areas in the Lambusango Management area with known varying degrees of human disturbance at present. Several forest characteristics were recorded (canopy cover, number of trees, tree circumference, tallest tree and the Braun Blanquet scale), to measure the effect of human disturbance on the forest and environmental characteristics (soil, gradient) were measured to determine the natural variation between quadrates and forest areas. The pandan plants themselves were also directly measured and counted. There were found to be three different growth patterns in the pandans recorded. Firstly a ground growth structure where the bud and leaves came straight out of the ground, secondly a tree type structure where a tree like trunk was present with the bud and leaves growing from the top, and thirdly a stilt root growth structure, which is the same as the tree type but with stilt roots to support the trunk. It was found that the size of the stilt root growth structure of pandan varied most noticeably in total height which directly correlated to disturbance levels: as human disturbance levels increased, the total height of the stilt root growth structure decreased. So in conclusion if pandans are to be used as indicator species many forest areas must be measured to minimise the local variation, and the total height of the stilt root growth structure is the best indicator.
