Finding the Corridor Potential Between Protected Areas in a Fragmented Landscape, Gunungkidul Regency, Indonesia

Abstract

Fragmentation impacts disconnecting protected areas in Gunungkidul Regency, namely Bunder Forest Park (BFP) and the Paliyan Wildlife Reserve (PWR). This also decreases the carrying capacity in PWR, degrading the Long-Tailed Macaque (LTM) habitat. Therefore, this research aims to analyze the landscape structure between Protected areas, the habitat suitability of LTM in Gunungkidul Regency, and determine connectivity potential as an environmental management strategy. applied for this research to investigates the structure and fragmentation using Fragstat 4.2 and ArcGIS 10.8 software. Meanwhile, scoring and weighting methods analyze the LTM habitat, while Least Cost Patch Analysis (LCPA) supported by ArcGIS 10.8 determine the corridor. The results showed that the research land cover changed from 1999-2021. Agriculture, scrubs, and settlements are the dominant land cover suspected to cause forest fragmentation. Based on the habitat suitability analysis using parameters such as land cover, vegetation density, slope, altitude, distance from the river, and sources of threats, most of the research area is intermediate habitat suitability class. These findings can be integrated to determine connectivity between protected areas as one of the environment management strategies. Good forest cover can be used to designate a corridor that has the greatest potential to be developed between BFP and PWR and should be maintained as a wildlife crossing.

Habitat fragmentation increases genetic distance between fruit bat subpopulations

“…Key strategies to ensure connectivity between Livingstone's fruit bat roosts and to maintain a viable population across the island include: (1) considering the Anjouan population as a single management unit, as genetic diversity is shared by individuals of different roosts (e.g. some individuals from Bazimini share alleles with ‘the rest’, Figure 2); (2) restoring forest and secure corridors between the sites of Bazimini–Mromaji and the southern region to promote dispersal across the island (Panuntun et al., 2023); (3) preserving the current suitable habitat for this species (see Ibouroi, Cheha, Astruc, et al., 2018) within protected areas; (4) involving a broad community of local individuals and entities in conservation and management to reduce anthropogenic pressure (Ibouroi et al., 2023).…”
