Abstract

The Sumberjati Resort Area, Perhutani Forest Management Unit (KPH) Jember, is a production area and protected forest. Habitat decline, overexploitation, and hunting of bird species result in their classification as endangered. This research aimed to ascertain the Bird Community Structure within the Sumberjati Resort, located in the Sempolan area of the Perhutani Forest Management Unit (KPH) in Jember. The study period encompassed the months of December 2022 to January 2023. The research uses the point count method at twelve observation points. The data recording process encompassed the collection of morphological data and bird population counts. A total of 34 distinct species, comprising a population of 1,292 individuals, were documented. Collocalia linchi exhibited the highest population density among avian species in every surveyed area. Spilornis cheela and Microhierax fringillarius have a conservation status of least concern according to the IUCN Red List and are protected bird species under the National Regulation. Shannon-Wiener index analysis shows that bird diversity is in the medium category (pine forest 1.32 ≤ jungle 1.33). The dominance index shows the medium category (pine forest 0.51 ≤ jungle 0.52). Evenness_e H/S is low (pine forest 0.16 > jungle 0.14). The highest relative abundance was Collocalia linchi (0.7063).
