KEANEKARAGAMAN JENIS BURUNG (Aves) DI ARBORETUM KHDTK AEK NAULI KABUPATEN SIMALUNGUN

Abstract

This study aims to determine the diversity of bird species and the abundance of bird species found in the Arboretum KHDTK Aek Nauli Simalungun Regency. The method used was a combination method between the point count method or IPA (Indices Ponctuele'dAbudance - Index of abundance at the point) and the Transect method. Data analysis used is by calculating the value of the species diversity index, the value of the abundance index and the value of the community similarity index. Observations were made using the path method (Transect). The length of the path is ± 1000 metres with an observation radius as far as the eye can see and the distance between the point count (Point Count) ± 200 metres. The observation time is ± 25 minutes, 15 minutes for observation at each point and ± 10 minutes is the time to walk to the next observation point. Observations were made in the morning at 06.00 - 09.00 WIB and in the afternoon at 14.00 - 17.00 WIB. The results of the research conducted found 16 bird species with a total of 221 individuals in the morning and 14 bird species with a total of 173 individuals in the afternoon, with a Diversity Index value of 1.95% in the morning and 1.85% in the afternoon, an abundance value of 0.12 in the morning and 0.13 in the afternoon, the value of the Community Similarity Index is known that the similarity of bird species present in the morning and afternoon has a similarity of 93%. This means that 93% of the species present in the morning and afternoon.
