CARRYING CAPACITY AND FEEDING PREFERENCES OF SUMATRAN ELEPHANTS (Elephas mazimus Sumatranus) IN THE ISAU-ISAU FOREST GROUP, LAHAT DISTRICT, SOUTH SUMATRA PROVINCE

Abstract

The habitat of the Sumatran Elephant (Elephas maximus Sumatranus) can be found in several types of forest, where naturally elephants need a large area to forage for food and spend time in primary (protected) forest during the day and out into open forest (secondary forest) during hot times. the sun has diminished. Elephants also need a safe and comfortable atmosphere so that their mating behavior (breeding) is not disturbed and their reproductive process can run well. This makes elephants very dependent on natural habitats to breed and find food. This research aims to find out what types of food preferences elephants have and the distribution of elephant food in the Natural Reserve Forest Area of the Isau-Isau Forest Group Elephant Training Center during ± 2 (two) Months.
