Identifying forest characteristics driving the density and range of the Sumatran elephant (Elephas maximus sumatranus) in the Leuser Ecosystem

​

Background Information

​

Rapid deforestation and growing pressures from anthropogenic impacts are  present severely affecting the wildlife of Sumatra,  where some of the fastest rates of tropical forest conversion are on-going.  Many of Sumatra’s endemic species, such as the Sumatran elephant (Elephas maximus sumatranus) are now at increased risk of extinction from widespread habitat loss and anthropogenic impacts.

 

This study aims to further understand the current distribution of the Sumatran elephant in the Leuser Ecosystem by gathering a first density estimate of the population at the Sikundur site, North Sumatra, and identify the forest characteristics that are most important for the species. The overall intended purpose of this study is to gain further knowledge regarding Sumatran elephant density and habitat requirments in Sikundur and the Leuser ecosystem and contribute to the scientific knowledge of the species as a whole . The study also aims to classify the dung decay rate of Sumatran elephants for the area of Sikundur, not just for this study but for future studies conducted in the area. This knowledge will not only enhance our current understanding of the distribution and habitat requirements of the Sumatran elephant, but also provide local Indonesian conservation agencies with the scientific understanding to support their conservation of this critically endangered species

Objectives

​

Obj. 1. Establish a first estimate of elephant density in Sikundur by following 1km long transects and counting elephant dung and signs of elephant habitat use

​

Obj. 2. Determine the types of habitat that are associated with the greatest elephant activity in Sikundur by recording vegetation characteristics  along the transects and when signs of elephant presence are encountered.

​

Obj. 3. Identify dung decay rates  in different environments using and monitor deterioration rates of dung to gather the dung decay rate for the area of Sikundur.
