Potential plants for wreathed hornbill (Rhyticeros Undulatus) feed in the Mendiro forest preserve, East Java.

The existence of Wreathed Hornbill in Mendiro forest preserves with disturbed and damaged forest conditions due to violations committed by the community such as land conversion, illegal logging, and hunting of wild animals. Based on these problems, it is a crucial consideration to research the potential of Wreathed Hornbill feed in Mendiro forest preserve. The research aims to determine the potential, types, distribution patterns, and diversity plant of Wreathed Hornbill feed in the Mendiro forest preserve. How to find out the types of plants that are classified as potential feed for Wreathed Hornbill through references to previous research journals and observed feeding behavior during data collection. The methods to analyze plants of Wreathed Hornbill use Line transect and put the square of analysis vegetation based on the presence of Wreathed Hornbill and potential plants of Wreathed Hornbill fed in Mendiro forest preserve. The results of the vegetation analysis found that the Wreathed Hornbill feed species in the Mendiro forest consisted of the Moraceae and Malaceae families with a total of 8 species. To determine the potential plant of Wreathed Hornbill feed uses the index of Important Score in each species. The highest potential plant for Wreathed Hornbill feed was, Ficus variegata (87,15%), Ficus racemosa (30, 46%), Ficus retusa (26, 36%), Artocarpus elasticus (21, 95%), Ficus hispida (17, 84%), and Ficus Benjamina (16, 79%), while the lowest potential plants of Wreathed Hornbill feed was Sterculia foetida (7, 77%). The pattern distribution plants of Wreathed Hornbill feed were random and exist almost in the Mendiro forest preserve area. The scores index diversity plants of Wreathed Hornbill feed was a medium level which scores arrange from 1,3 to 1,8. Based on the condition of the relatively few Wreathed Hornbill feed, it is better to establish good cooperation in protecting even more plants of Wreathed Hornbill feed in the Mendiro forest preserve.
