Diversity, Composition, and Abundance Distribution of Birds in Kariangau Industrial Zone, Balikpapan City, East Borneo

Abstract

The Kariangau Industrial Zone extends industry from Balikpapan city in the Central Balikpapan to the coast in Western Balikpapan, forming a part of Balikpapan Bay. Our study aimed to estimate the diversity, species composition, and the abundance distribution of birds at the industrial zone of Balikpapan City. Our study contained six replicates each of boat transects on four rivers, the Somber, Getah, Paka Dua, and Wain rivers during the months of May and June 2017. We calculated the Margalef diversity and Bray–Curtis similarity indices to estimate diversity and species composition, whereas bird abundance distributions were analyzed using Paleontological Statistics (PAST) version 3.12. The Getah river had the highest diversity index (4.846), followed by the Somber (3.988), Wain (3.510), and Paka Dua (3.050) rivers. The Bray–Curtis index revealed high similarity in species composition between the Wain and Paka Dua. Our rarefaction analysis showed that the Wain and Paka Dua rivers were well sampled and had lower species richness, with low differences between the observed and expected species richness, than the Somber and Getah rivers. Fisher Log Series Model also showed abundance distribution being highest at Getah (11.170), and lowest at the Paka Dua Rivers (5.221). This observation may be due to heightened industrial activities and boat traffic on each river. Our study provides a useful baseline for future research on the bird assemblages on Balikpapan Bay.

Locating the unique biodiversity of Balikpapan Bay as an ecotourism attraction in East Kalimantan, Indonesia

“…According to Lhota (2010), the mangrove forest in Balikpapan Bay has nearly 300 species of birds. Just within Kariangau Industrial Zone extending from the Centre of Balikpapan city to the coast in Western Balikpapan, Putera et al (2018) claimed that 34 species of birds are recorded, of which two species are categorized as vulnerable (VU) by IUCN, namely: the Short-toed Coucal (Centropus rectunguis) and the Lesser Adjutant (Leptoptilos javanicus).…”

Composition and seasonality of avifauna found near the National Thermal Power Corporation area of Angul district, Odisha, India

“…These industries are the major stockholders of the economy of any region and also are an integral part of economic development. Apart from their primary purpose, it is evident that industrial areas create negative impacts for the surrounding environment, as well as on the local avifaunal wealth (Jay et al, 2007;Yanhua et al, 2011;Mardiastuti et al, 2018;Putera et al, 2018). Birds have high ecological value because of their important roles as (1) excellent proxy taxa for detecting any environmental changes, (2) best insect control agents, (3) seed dispersers and (4) pollinators (Stratford and Şekercioğlu, 2015).…”

Waterbird Foraging Habitat Selection in Balikpapan Bay: Water Depth and Patch Area as Important Factors

“…The waterbirds such as heron and stork are commonly fed on the mudflat and fish-shrimp ponds (Kirby et al 2008). Some waterbirds from Ardeidae and Ciconiidae can be found in Balikpapan Bay (Putera et al 2018;Putera 2020). They are purple heron (Ardea purpurea), little egret (Egretta garzetta), great egret (Ardea alba), and lesser adjutant stork (Leptoptilos javanicus).…”
