Bird diversity in several land use types in Boyolali, Central Java

Abstract

Land use changes were thought to affect the diversity and feeding guilds of bird species. This research aims to determine the effect of five land use types (rice fields, settlements, cropland, tree plantation, and secondary forest) on species diversity and feeding guilds of bird species in Boyolali Regency. Methods used were the standard point count and the MacKinnon species list. Bird data were analyzed using the Margalef richness index, Shannon-Wiener diversity index, Pielou evenness index, and Sorensen community similarity. The total species recorded was 46 species from 26 families. The land use types with the lowest to the highest number of species are settlements, rice field, tree plantations, cropland, and secondary forests. The highest number of species found was in secondary forest (n = 25), along with the highest richness (DMg = 4.17), diversity (H′ = 2.689), and evenness (J′ = 0.835) indices. Although the secondary forest has the highest number of species and indices, other land uses in rural areas also serve as good bird habitats. The insectivorous, frugivorous, and granivorous guilds were found in all land use types. The carnivorous guilds were only found in secondary forests.

Bird diversity in Aketajawe Lolobata National Park

“…The results of this study are inversely proportional to the research by (Dewi et al, 2007) conducted in Gunung Ciremai National Park, which found more birds in the primary forest namely 62 species. Meanwhile, other research that is in line with this research indicated that other habitats decreased bird numbers while secondary habitats increase the richness of bird species (Rohman et al, 2023;Tu et al, 2020). This can occur due to differences in the diversity of vegetation types in secondary and primary forests, the number of days, and observation plots.…”
