The Diversity, Distribution and Feeding Guild of Mammals and Birds in Institut Teknologi Sumatera (ITERA) Landscape

Abstract

ITERA was established in 2014 and caused a landscape conversion from a rubber plantation into a construction area. Changes in a landscape usually affect wildlife biodiversity such as mammals and birds. The objective of this research is to identify and to determine the diversity, distribution, and feeding guilds of mammal and bird species. A survey of mammals and birds in the ITERA landscape has conducted between April and September 2019. This research used line transect and trapping method for mammals. The combination of point count and transect method used for birds observation. ITERA Landscape divided into six transects. This research found three species mammals belonging to three families. C. notatus only found in rubber stands. 67% of terrestrial mammals and all feeding guilds are omnivorous. This research found 814 encounters of birds consisting of 28 species belonging to 18 families. Species with the highest dominance are Lonchura punctulata, and the dominant family is Ardeidae. Elanus caeruleus and Ardea alba are a protected species which stated in Indonesia regulation. The transect that has the highest species richness is transect 6 with 22 species, and transect 1 with 21 species. The highest stratification used for foraging of birds community is terrestrial, and the highest feeding guild is insectivorous.
