Protected areas in the Hindu Kush Himalaya: A regional assessment of the status, distribution, and gaps

Abstract

<p>Protected areas (PAs) are a key strategy for conserving areas of outstanding biodiversity value and promoting sustainable development. Significant efforts have been made toward establishing PAs over the last few decades across the globe. However, an assessment of PAs in mountain regions, including in the biodiversity rich Hindu Kush Himalaya (HKH), is lacking. We assessed the status, trend, and distribution of PAs and the ecological representativeness in the PA network. Our analysis showed the HKH has a total of 575 PAs covering 40.17% of the region, accounting for 8.49% of global PA coverage. The HKH hosts 335 Important Bird and Biodiversity Areas (IBAs), 348 Key Biodiversity Areas (KBAs), 12 Global 200 Ecoregions, and 4 Global Biodiversity Hotspots. However, the study showed limited ecological representation in the current PA system as 67% of ecoregions, 39% of hotspots, 69% of KBAs, and 76% of IBAs are still outside of the PA system. About 47% of the PAs are small (<250 sq. km) with no connectivity to other PAs and the majority are distributed in the lower reaches of the HKH. These findings suggest the need to assess and demarcate potential corridors to improve connectivity between PAs and integrate PAs into wider conservation landscapes at national and regional scale beyond country boundaries through regional cooperation. There is also a need to assess and strengthen PA management effectiveness and governance and consider other effective area-based conservation measures especially in the higher elevations and with a specific focus on ecological representation.</p>
