SUMMARYMultifaceted patterns of protected area (PA) expansion are reviewed considering: i) the increase in PA number and coverage; ii) distribution and extent of important bird areas (IBAs); and iii) distribution and coverage of global biodiversity hotspots and the Global 200 Ecoregions that fall within the Hindu Kush-Himalayas (HKH). The analysis revealed that biodiversity conservation is a priority for the eight regional member countries of the HKH, who have established 488 PAs over the last 89 years (1918 to 2007). The eight countries sharing the HKH have committed 39% of this total geographical area to the PA network and 11% to IBAs, which is quite significant when compared to the global target of 10%. There has been an increasing trend in PA establishment over the last four decades. The PA coverage within the HKH of China alone is significant (35.5%), followed by India (1.46%) and Nepal (0.58%). When IUCN management categories are considered, the majority of PAs belong to Category V (39%), followed by Category IV (29%). Only 0.6% of PAs are managed as Category I, and, in recent years, Categories V and VI have increased. Of the total HKH geographical area, 32% is covered by four global biodiversity hotspots and 62% by the Global 200 Ecoregions. However, only 25% of the global biodiversity hotspots and 40% of the Global 200 Ecoregions are part of the PA network. There are still numerous gaps in conservation in the HKH. Coordinated and committed efforts are required to bring other critical habitats within the PA network in the HKH.
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.
