Small mammal assemblage in Gunung Tebu Forest Reserve, Terengganu: An environmentally sensitive area in East Coast Peninsular Malaysia

Abstract

Effective spatial planning plays a pivotal role in defining the progress and growth of a certain region. One aspect of spatial planning by PLANMalaysia involves the incorporation of environmentally sensitive areas (ESAs), which comprises eleven different landscape management. Integrating biological features is crucial when defining ESA Permanent Forest Reserve, as relying solely on physical attributes may not accurately reflect the true sensitivity of the environment. Therefore, there is a need to gather biological information to strengthen existing ESA. A study was conducted in Gunung Tebu Forest Reserve (GTFR) from April to July 2023. Multiple trapping approaches were deployed to assess volant and non-volant small mammal assemblage. In total, 155 individuals comprised of 31 species of small mammals were documented with the highest species abundant recorded by Maxomys rajah (n = 29) and Leopoldamys sabanus (n = 27). The diversity indices were varied throughout five sampling sessions, (Shannon = 1.841 to 2.543), (Simpson = 0.7951 to 0.9056). Comparison on species assemblage between GTFR and forest reserves in Hulu Terengganu showed a moderate similarity level. This finding offers the most recent insight of the small mammals in GTFR and highlights the significance of conserving and preserving (ESA) in permanent forest reserves.
