Summary: | Bawean deer (Axis kuhlii) is an endemic species to Bawean. Habitat change and loss, land conversion,
and over exploitation affect the availability of potential food for Bawean deer. The aims of this research were to
identify types of potential food for Bawean deer in Bawean Wildlife Sanctuary, the abundance of potential foods
in Bawean Wildlife Sanctuary and the diversity of such potential foods. Data collected using line transects
whose length was adjusted according to field condition. The line transects were located in parallel to natural
trail of study area. Observation was done in the plots established along transect, where plant being eaten by
Bawean deer was found. Plot has a circular form with diameter of 3'.14 m. Distance between plots was
determined to be 100 m. Indicators used to collect data were feces, footprint and bite or chew mark on food
plants. Identification of plant species was conducted directly for every plant which showed bite or chew mark.
Data concerning type of plant and its number, part of plants which was bitten or chewed and plant height were
recorded. Abundance will be determined from the number of potential foods in each location. The results were
afterwards compared among three forest regions. The diversity of food plant species was determined using
Shannon index. The result showed that there are 29 plants considered as potential food for Bawean deer. Most
of the plants are grasses, and herbs, while woody plants arefound in a small number. Leaves, shoots (buds) and
fruits are part of plant often being eaten. There are 14food plants occurred in Gunung Mas forest region, 27
food plants were found in Gunung Besar forest region and 13 food plants in Tanjung Cina Island. Taliata,
rumput padang and gadung have high abundance in Gunung Mas forest region, the smallest abundance was
occupied by kayu ilat. Kabek-kabekan putih, lading-ladingan and taliata showed the highest abundance in
Gunung Besar forest region, while karangsang has the lowest abundance. In Tanjung Cina Island, high
abundance was dominated by gadung, taliowar and lading-ladingan. On the other hand, talicacing, kayu tekek
and rombok putih showed low abundance. Among three study areas, Gunung Besar forest region has the
highest diversity index, followed by Gunung Mas forest region and then Tanjung Cina Island. |
