Long term ecological monitoring of biodiversity is practicable with an inventory of its floral and faunal diversity. With this view, the documentation of biodiversity of the two fenced areas of Dhanolti reserve forest of Mussoorie forest division has been prepared.

During preliminary investigation of spiders in Milam Valley, Nanda Devi Biosphere Reserve, the authors documented a total of 86 species/morphospecies under 39 genus and 16 families. Spider fauna in the valley was rich and diverse.

The Indian Himalayan Region (IHR) is well recognized for its ecological, hydrological and aesthetic values and is considered as the repository of biological and cultural diversity. Western Himalaya is an important area for bird diversity and harbours several regional endemic species and has been desginated as Endemic Bird Area (EBA 28).This study was carried out to scrutinize the diversity of the birds at different types of vegetation around NDBR (Nanda Devi Biosphere Reserve), Uttarakhand.

A study was conducted to document spider diversity in Kedarnath Wildlife Sanctuary, Chamoli District, Uttarakhand. The area is dense forest of Chir Pine, Oak, Birch and Rhododendrons.

40 species of butterflies, under 26 genera and 5 families were recorded from four habitat types of Allain-Duhaingan (streams) catchment, where a hydroelectric power station is proposed.

The efficacy of spider as indicator of habitat conditions in Tarai Conservation Area was examined. To compare habitat specific spider communities, five vegetation types were sampled from March 2005 to August 2006 by using pitfall traps and other semi-quantitative collection methods along transects.
