Abstract

The Critically Endangered Cacatua sulphurea abbotti is a unique subspecies of cockatoo, endemic to a single tiny Masakambing Island in Indonesia. Data procurement on the status and distribution of their wild population is urgently needed to determine the best conservation strategy for this species. Data were collected annually from 2008–2018 using a direct roost count method in a roosting tree. Only 10 cockatoos were recorded in 2008, but the number increased to 22 birds in 2018 (a 42.86% increase in a decade). The population was distributed across about 71% of the total area of the island, concentrated in the north-western part with a density of 1.56 (~2 birds/km²) in 2008, which increased to 3.44 (~3 birds/km²) in 2018. The zero-trapping policy enforced by the local government was likely effective in preventing population decline, although the population remains vulnerable due to nesting failure, presumably low genetic quality, and habitat destruction.

Abstract

Southern Cassowary (Casuarius casuarius) is  a seed disperser of North Australia and Southern Papua lowland forest ecosystem. Despite its dominant distribution in Southern Papua, there is a lack of information regarding its population and habitat characteristics. Due to its high sensitivity, the southern cassowary is rarely seen across the forest, yet the signs of its presence (feces and footprints) are abundant. This study analyzed the distributions, population, and habitat characteristics of the southern cassowary’s in Sota and Wanggo Resort, Wasur National Park, Southern Papua. Maximum Entropy results showed that its distribution focused on the northeastern area of Wanggo Resort and several points north of Sota Resort. Using fecal distance sampling, this study found that the southern cassowary population density in Wasur National Park areas was 0.8 ind/km2, primarily in lowland forests. The area corresponds to the variables that most influence the southern cassowary, which are NDVI, annual precipitation, and distance to the road. These findings underscore the urgency of local stakeholders to pay specific attention to lowland forests in Wasur National Park.

Abstract

Gunung Halimun Salak National Park (NP) is recognized as an important habitat for rare or key species of Java Island such as the Javan Hawk-eagle, Javan leopard, and Javan gibbon. Although these species exhibit different movement patterns (aerial, arboreal, and terrestrial), their spatial overlap within the landscape suggests potential ecological interactions, particularly within the trophic structure which is rarely integrated before. This study aims to identify, describe, and provide recommendations for the management of key species shared habitats based on spatial approach. Spatial analysis was used to examine the distribution of shared habitats and their biophysical characteristics, including land cover, elevation, and slope. A literature and policy review was conducted to align the findings with existing Conservation Strategies and Action Plans, based on applicable regulations and NP zonation. The analysis reveals that habitat distribution within the NP is categorized into 28.78% two key species and 55.84% three key species shared habitat. Biophysically, key species shared habitat is primarily found in forested areas between 500–1,500 meters above sea level (masl), and mostly located on steep slope around 25–45%. In terms of Gunung Halimun Salak NP zonation, two key species and three key species habitats are mainly located within the core, forest, and use zones of the Gunung Halimun Salak NP. The recommendations are developed aligned with the Conservation Strategy and Action Plan, regulations, and NP zonation for the comprehensive and integrated habitat management strategies of the key species shared habitat.
