Abstract

This study was carried out to determine the influence of types of substrate (trees, rocks, soil and dead wood) and the effect of light intensity on lichen distribution in Kinabalu Park, Sabah. Two study sites were selected: the first site is located at an elevation of 2900 meters while the second site is located at an elevation of 3300 meters above sea level. Quadrats were used to sample lichen specimen from these sites. Ten 1 m X 1 m quadrats were used for the first sampling site while thirty 10cm X 20cm quadrats (10 quadrats each for each light intensity) were set at second sampling site. The surface area of lichen found in each quadrat was taken to represent the abundance of lichen in the quadrat. A total of 32 species of lichen from 19 genera and five unidentified specimens were collected from both sites. The types of substrate which influence the distribution of lichen were tested. The results show that 65% of total surface area of lichen was found on trees, while only 4% of lichen was found on soil. The distribution of saxicolous lichens was not affected by light intensity. The result of One-way ANOVA (p>0.05) shows that there was no significant difference between lichen growing at high, medium and low light intensity.
