The Hindu Kush Himalayan region (HKH) is an important biodiversity repository with more than 488 protected areas covering 39% of the region?s geographical coverage
. However, a majority of them are small and isolated and are not large enough to address conservation challenges. About 20% of the protected areas are transboundary in nature. Conservation landscape planning based on habitat suitability is an essential step for landscape management, but there are limited data available from the Landscape Initiative for Far Eastern Himalayas (HI-LIFE). To rationalize the need for regional cooperation, this study used remote sensing (RS) data and a geographic information system (GIS) to estimate the habitat suitability for four globally significant speciesconsidering available but limited secondary information. The results showed variation in habitat suitability at an individual species level, but the combined map showed about 43% of the total area as a suitable habitat. Substantial amounts of suitable habitat also recorded from outside the existing protected areas. The results also highlighted the fact that 75.40% of the existing forest within the landscape is intact, the majority of which is outside the existing protected areas. Thus, there is a strong rationale and opportunity to strengthen regional cooperation to safeguard irreplaceable and unique biodiversity resources of this wilderness landscape

The Far-Eastern Himalaya Landscape (FHL), a shared transboundary landscape between China, India, and Myanmar, is one of the most intact and biologically rich landscapes in the Eastern Himalaya
. Yet, the state of biodiversity and its significance are comparatively poorly known to conservationists and policy makers due to low priority in research, inaccessibility, and remoteness. We collated and reviewed 1032 articles relating to biodiversity of the FHL to understand research trends, identify knowledge gaps, and suggest priority research areas for future biodiversity conservation and management in the landscape. Our review showed that the Myanmar part of the landscape is the most studied, followed by the Indian and Chinese parts. The trend of publications in the landscape showed that the earliest publication on biodiversity in the FHL dates back to 1833, while the years from 2001 to 2017 account for almost 80% of the total publications. Most studies focused on species (73.6%), followed by ecosystems (25%) and genetics (1.4%). Mammals were the most studied taxa (22.6%), with a greater focus on charismatic megafauna, followed by arthropods (15.6%), angiosperms (14.8%), insects (13.4%), and birds (10.8%). There were very few publications on lower invertebrates and lower kingdoms, Monera, Protista, Fungi, and Viruses. At the ecosystem level, most studies focused on forests (58.5%) followed by freshwater (32%), agroecosystems (9%), and alpine/tundra ecosystem (0.5%); there were only 14 studies at genetic level. In the FHL, new species have been discovered and rediscovered starting from the early 1930s until 2017. The majority of newly discovered species in the last 18 years are arthropods. The paper reviews past research areas, identifies gaps for future research and intervention, and recommends transboundary collaboration to address these gaps for conservation and sustainable development of the FHL landscape
