Replication data for: Flowering phenology of tree rhododendron along an elevation gradient in two sites in the Eastern Himalayas

Rhododendron arboreum Sm. is one of the most important components of the ecosystem as different individuals tend to bloom from early spring to early summer, maintaining pollinator populations with their profuse flowering over a wide variety of habitats in the temperate to subalpine regions. As many other organisms depend on the R. arboreum, its phenology is very important to study for knowing ecosystem and a ffect of changing environment on phenological events of this species. In this paper relation of flowering phenology with various environmental parameters was studied to show effect of chosen variables on the flowering phenology of R. arboreum in two sites in Eastern Himalayan region.
