“…Consequently, our deforestation risk model predicts that one third of the predicted deforestation may occur within the boundaries of the protected area network. Poor et al (2019) found that the role of protected areas in effectively curbing deforestation should be strengthened, although protected areas in Sumatra already have the advantage of practical protection afforded by its location at rather high elevation typified by rugged slopes that discourage deforestation through the expense of access.…”

“…With the current pace of infrastructure development, managers of conservation areas face two substantial challenges in (1) mitigating the impacts of accelerated deforestation rates in central Sumatra; and, (2) ensuring national policies and conservation programs are well-communicated and integrated into provincial and district government plans (Poor et al 2019;Sloan et al 2019). In the meantime, national government restrictions on new road developments and/or expansion of existing roads that transect national park forests, e.g.…”

Context Effective planning for protected areas and wildlife population management requires a firm understanding of the location of the species’ core habitat patches, the dispersal corridors connecting them, and the risk they face from key threats, notably deforestation. Objectives To quantify and map core habitat patches and dispersal corridors for Sunda clouded leopard (Neofelis diardi diardi), Asiatic golden cat (Catopuma temminckii) and marbled cat (Pardofelis marmorata) across the 16,000 km2 tropical rainforest Kerinci Seblat landscape, Sumatra. Also, to model future forest loss and fragmentation and its effect on landscape connectivity for populations of these threatened species. Methods Using data from camera trap (671 sites/55,856 trap nights), and occupancy modelling, we developed habitat use maps and converted these into species-specific landscape resistance layers. We applied cumulative resistant kernels to map core areas and we used factorial least-cost paths to define dispersal corridors. A 17-year deforestation dataset was used to predict deforestation risk towards the integrity of corridors and core areas. Results The occupancy estimates of the three cats were similar (0.18–0.29), with preference shown for habitats with dense tree cover, medium elevation and low human disturbance. The overlap between core areas and corridors across the three species was moderate, 7–11% and 10%, respectively. We predicted future loss of 1052 km2 of forest in the landscape, of which 2–4% and 5% in highly importance core areas and corridors. Conclusions This study provides a valuable guidance for identifying priority areas in need of urgent protection within and outside the protected area network, and where infrastructure development planning can incorporate wildlife conservation goals.

“…Accordingly, we sought to analyse deforestation leakage in buffer zones with areas relatively equal to those of their respective PAs. Previous studies analysed leakage within 10 km buffer zones (Fuller et al, 2019;Lui & Coomes, 2016;Poor et al, 2019). However, this buffer radius produces buffer zones with areas similar to that of the PA only when the PA is relatively large (c. 2,000 km 2 ).…”

“…We used distance to the nearest major road, distance to the nearest major population centre, mean elevation, country and terrestrial ecoregion as covariates for PSM, with exact matching on country and terrestrial ecoregion (EEA, 2016;Environmental Systems Research Institute, 2018;Natural Earth, 2018;Olson et al, 2001). We chose these covariates because they can affect rates of deforestation and have been used in many other statistical matching studies (Andam, Ferraro, Pfaff, Sanchez-Azofeifa, & Robalino, 2008;Mas, 2005;Poor et al, 2019). We used the PS Matching extension to establish callipers that defined a tolerance outside of which matches were excluded from the sample (D'Agostino, 1998).…”

“…The planned highway entails segments crossing the last major domain of remnant forest along the island's central uplands (Figure 1). Remnant forests in Sumatra have recently been degraded or lost following nearby road developments (Clements et al, 2014;Linkie, Smith, & Leader-Williams, 2004;Wich et al, 2016), including in national parks (Poor, Frimpong, Imron, & Kelly, 2019;Poor, Jati, Imron, & Kelly, 2019), and we presume this trend will continue. Here, we highlight three remnant forest areas that are critical to Sumatra's ecological integrity and which face conservation challenges that the Trans-Sumatra Highway would aggravate ( Figure 1).…”

Road-infrastructure development in Southeast Asia is opening new resource frontiers but also consolidating earlier investments in agriculture and trade, as illustrated by the 2,700-km Trans-Sumatra Highway planned for Sumatra, Indonesia. In contrast to earlier broadscale forest losses in Sumatra, driven historically in Sumatra infrastructure and agricultural expansion, the Trans-Sumatra Highway would largely affect remnant forests. We identify Kerinci Seblat National Park and its surrounds, the Leuser Ecosystem, and the Batang Toru area as three remnant-forest areas critical to Sumatra's ecological integrity and facing conservation challenges that would be significantly aggravated by the Trans-Sumatra Highway. If completed as planned, the highway will promote human incursions into the fringes of these areas. New Indonesian regulations concerning road developments in forests are unlikely to prevent such outcomes. The regulations afford weaker protections to ungazetted and noncore protected forests, which typify remnant-forest areas threatened by infrastructure expansion and are often critical for species conservation. We urge that ungazetted protected forests be given equal priority to gazetted protected forests in regard to conservation planning for road development, and also that gazetted forests be expanded in the Leuser Ecosystem and Batang Toru area to hedge against further incursions. Without such provisions, recent legal challenges to road developments in Sumatra's remnant forests have often been unsuccessful. The Trans-Sumatra Highway may conceivably promote an effective legal alliance between conservationists and agricultural communities threatened with land expropriation, given that nearly half of the highway's route remains pending contentious land-acquisition processes.
