摘要

The Western Himalayas region, including Himachal Pradesh, Uttarakhand, and Jammu and Kashmir, reserves more than 240 species of orchids that occur over complex ecological gradients between subtropical valleys and alpine meadows. Although the sexual reproduction of orchids is fundamentally reliant on animal-mediated pollination, there is a dire lack of empirical studies that link orchid taxa with their insect pollinators in this biogeographically important area. There is a strong emphasis on taxonomic listings and conservation status reports in existing literature but a complete lack of direct observation studies of pollinator identity, forage behaviour, pollen transfer effects, and phenological synchrony. This review includes the peer-reviewed literature on Western Himalayan orchids and their pollination relationships. It indicates clearly that significant gaps in research exist, such as a lack of published pollination networks and experiments. These results clearly indicate that, given the rapid rate of environmental change, there is a pressing need to conduct certain studies that may be used to inform effective evidence-based conservation policies.
