Abstract:
Birds are easy to find and use to monitor revegetation developments. The purpose of this research was to record bird species found in revegetation areas and to measure species diversity and community similarities. Four locations with different revegetation years in PT Adaro Indonesia, South Kalimantan Province were used as sample locations for data collection in November 2019. Diurnal bird species and the number of individuals were recorded through the pathway and abundance point method. The researcher walked slowly along pathways (inspection road) up to 500 m while observing the left and right of the road within a maximum distance of 50 m. Data collected twice for each location. Data were tabulated and calculated to obtain a diversity indexes (Shannon-Wienner) and community similarity indexes. Of the 35 species (22 families) of birds, 11 species (H '= 2.01) were found in the 2014 revegetation area, 20 species (H' = 1.97) in the 2015 area, 25 species (H '= 2.74) in the 2016 area, and 10 species (H '= 1.18) in the 2017 area. The community similarity index based on species presence ranged from 0.29 ‒ 0.65 and based on the number of individuals ranged from 0.41 ‒ 0.89. In general, the similarity indexes based on the presence of species are smaller than that based on the number of individuals, although there is exceptional case where the value is greater.
