The Sumatran Rhino Sanctuary is the only place where semi-Sumatran rhinos in Indonesia have been conservation, located in Way Kambas National Park which has never been revealed through systematic research on its capacity to support its function as a conservation site for rare species such as the Sumatran rhinoceros (Dicerorhinus sumatrensis). This study was conducted in August 2015 which aims to determine changes in the type and potential of natural feed, palatability of feed, potential water availability, and the cover of Sumatran rhinoceros habitat. This study uses a sample plot method. Data on carrying capacity of the collected habitat are data on the potential of feed plants, the level of rhino preference for feed types, water availability and habitat cover. The results showed that the number of feed species in the understorey phase increased, in the liana phase, seedlings, stakes and poles decreased, whereas in the tree phase there was no change because the number of species found was the same. Palatability of food has changed, in 2001 the rhinoceros favoured was a species of Psychotria sclerophylla while in 2015 it was a species of Planchonia valida. Changes occur in the potential for water availability, in 2001 14 water sources were found while in 2015 8 were water sources. In environmental factors, there is an increase in the intensity of light in the puddle, under the canopy, and the river, but in the swamp, there is a decrease in the intensity of sunlight, the average air temperature increases, and the average air humidity decreases.
