Birds are reliable and widely used indicators for conservation planning and monitoring. We reviewed birds of the Kangchenjunga Landscape, a transboundary complex shared by Bhutan, India and Nepal in the Eastern Himalaya. Using 119 literature, we analyzed the bird survey efforts in the landscape, their taxonomic representation, global threat status, distribution patterns, and habitat preferences. We also discussed the potential threats and conservation challenges and documented current conservation efforts and government policies. Most of the bird surveys are carried out in India followed by Nepal and Bhutan. A total of 618 bird species belonging to 19 orders and 77 families are recorded. Passeriformes is the dominant order that constitutes 62% of the total records listed from the landscape. Among the families, Muscicapidae is the most common and diversely represented family. There are 41 species of birds that are categorized as threatened under IUCN Red List. Of the total birds occurring in the landscape, the highest number of bird species(95%) was documented from India, followed by Nepal(55%) and Bhutan(34%). Of them, 24% of the species were found to occur in the tropical zone. Forested habitat is widely used by 63% of the total species followed by wetlands(16%). Despite promising policies and legal provisions, the landscape faces numerous challenges including habitat loss and fragmentation, hunting and trapping, unsustainable extraction of natural resources, invasive alien species, unregulated tourism and global climate change. We suggest protection and management of birds through strengthening Important Bird and Biodiversity Areas, reduction in forest encroachment and habitat destruction, conservation awareness programmes and comprehensive bird surveys with long term monitoring to assess the impact of environmental change as some of the approaches to conserve the rich avifaunal diversity of the landscape.

The Kangchenjunga Landscape (KL) in the Eastern Himalayas is a transboundary complex shared by Bhutan, India, and Nepal. It forms a part of the ‘Himalayan Biodiversity Hotspot’ and is one of the biologically richest landscapes in the Eastern Himalayas. In this paper, we use secondary information to review and consolidate the knowledge on the flora of the KL. We reviewed 215 journal articles, analysed the history of publications on the flora of the KL, their publication pattern in terms of temporal and spatial distribution and key research areas. Our review shows that the landscape has a long history of botanical research that dates back to the 1840s and progressed remarkably after the 1980s. Most of the studies have been carried out in India, followed by Nepal and Bhutan. The majority of these have been vegetation surveys, followed by research on ethnobotanical aspects and Non-Timber Forest Products (NTFPs). This paper describes the forest types and characteristic species of the KL and details the species richness, diversity and dominant families of seed plants. A total of 5198 species of seed plants belonging to 1548 genera and 216 families have been recorded from the landscape, including 3860 dicots, 1315 monocots and 23 gymnosperms. Among families, Orchidaceae is the most diversely represented family in terms of species richness. This paper also draws attention to the threatened and endemic flora of the KL, including 44 species that are threatened at national and global level and 182 species that are endemic. Finally, the paper reviews the major challenges facing the KL, the conservation efforts and practices that are currently in place and recommends systematic and comprehensive floral surveys, particularly long-term data collection and monitoring and transboundary collaboration, to address the existing knowledge gaps on floral diversity of the KL.
