Tropical forests have been extensively exploited and cleared for various reasons over the past years. Therefore, conservation emphasis has been given to protect natural forests and to assist regeneration of secondary forests. In the current study the composition and abundance of bird species in a natural forest (NF) and an adjacent regenerating forest (RF) in Maragamuwa, Naula in the Matale District were compared using a point count integrated line transect method. A clear variation was seen in the bird composition, diversity and evenness in both forest types and also during different time sessions of the day. In all the instances the values shown by the RF was greater than that of the NF and the species evenness showed high values for both forest types. The species composition showed no seasonal variation in NF throughout the study period while RF showed a seasonal variation. The endemicity of birds in the NF was higher than that of the RF. Hence, the current study shows that early successional forests support a rich bird diversity while the species richness of endemic bird species increases thereby enabling these measurements to be used as indicators in long term conservational practices.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
