STRUKTUR DAN KOMPOSISI JENIS BURUNG DI KEBUN RAYA MEGAWATI SOEKARNO PUTRI, KABUPATEN MINAHASA TENGGARA

Abstract

ABSTRACT

This study aims to make an inventory of bird species in the KRMSP area, and analyze changes
in the structure and composition of its bird species. This research was conducted in September 2020 at
Megawati Soekarno Putri Botanical Garden, Ratatotok, Southeast Minahasa, North Sulawesi. The
method used in this research was the IPA method (Indice Ponctuels d'Abondance) with priority
observation points in the reclamation areas of years 2000, 2001, 2002, 2003/2004 and 2006/2007. This
research covered a total of 15 observation points in 5 reclaimed areas. Results observed 896 bird
individuals, divided into 26 families and 44 species. Results were analyzed using the Shannon-Wiener
diversity index, resulting in a diversity value of 2.92. Comparative analysis of bird species
composition from 2008, 2009 and 2020 showed an increase on bird species and families as well as a
significant decrease in the number of individual birds observed. Comparison of Shannon-Wiener
diversity indices in years 2008, 2009 and 2020 show a moderate diversity value across all years. The
diversity index value in 2020 (2.92) is lower than in 2008 (2.94).
