Abstract

The restoration effort in Tamban Beach may reflect the role services of mangroves as suitable habitats for those surrounding diversity, especially on avifauna. Here we assess the diversity and community of avifaunal throughout types of mangrove ecosystems. We surveyed the avifaunal within four stations (i.e., natural mangrove area, restored mangrove area since 2009 and 2014, and degraded mangrove area) in Tamban Beach, Sumbermanjing Wetan, East Java during March 2021 using Audiovisual Encounter Survey (AES) methods. We present the statistic descriptive analysis of α-diversity index (taxa diversity, dominance index, Simpson’s index, Evenness, Shannon-Wiener diversity index, Brillouin index, and Margalef species richness) as diversity assessment also conservation status of each species. The Principal Component Analysis (PCA) was performed to investigate the community variation within each site. We found 38 species from 22 families and 11 orders of avifaunal across the sites. The diversity of avifauna was high in a degraded area due to the mixture of habitats, although the natural and restored area yields some specialists. The type of mangroves might not be the sole factor affecting the avifauna diversity correlation, highlighting the importance of conservation strategies in the area.

Abstract

Avifauna inhabiting mountain forest ecosystems on Java Island face severe threats from anthropogenic disturbances. Despite this, the diversity of avifauna in specific areas, such as the Hutan Lindung Pegunungan Putri Tidur (HLPPT) on the slopes of Mount Kawi, remains poorly monitored. This study focuses on assessing avifauna diversity and communities in the tourist area of Mount Kawi slope waterfalls, situated on both the southeast side in Malang Regency and the north side in Batu City. The research, conducted from January to March 2022, examined eight waterfall locations (Baung, Glotak, Luksongo, Parangtejo, Manten, Tengah, Rondo, and Sumberpitu) using the roaming method with Visual Encounter Survey (VES) and Audiovisual Encounter Survey (AES) techniques. Data analysis included considerations of conservation status, local distribution, feed specialists, diversity indices (Taxa Richness, Shannon-Wiener Diversity Index (H’), Simpson Index (D), Evenness Index (E)), and Important Value Index (IVI) as an assessment of avifaunal diversity. Researchers employed Microsoft Excel and Principal Component Analysis (PCA) to determine preferences for each character diversity index and abiotic factors in each location. Across the site, 84 species from 33 families were identified. Notably, seven species were classified as at risk (4 near-threatened, two vulnerable, and one endangered), and nine avifauna were protected. The correlation of avifauna diversity to biotic and abiotic factors was positive. These results provide essential data for further conservation management, emphasizing the protection of the forest area, tourists, waterfalls, and slopes of Mount Kawi. Additionally, studying spatial and temporal distribution is crucial for future avifauna species re-inventory efforts.
