The corridor connecting the Toorsa Strict Nature Reserve (TSNR) and Jigme Dorji National Park (JDNP) in western Bhutan is an important component of the Kangchenjunga Landscape, which links protected areas in western Bhutan with those in India. The TSNR-JDNP biological corridor has been endorsed by the Royal Government of Bhutan as an integral part of the Bhutan Biological Conservation Complex (B2C2). B2C2 encompasses interconnected area of more than 15,000 sq. km in Bhutan with twelve biological corridors and nine protected areas. The TSNR-JDNP biological corridor has the potential to considerably facilitate ecological processes, wildlife movement, and gene flow within the entire B2C2, as well as across the border in India. The corridor is 30 km in length and has an area of 149 sq. km. The corridor falls within the Bji geog (Haa Dzongkhag) and Tsento geog (Paro Dzongkhag) in western Bhutan. Two major tributaries namely, Pachhu and Haachhu, that feed to the Wangchu River System, have its catchments in this biological corridor. The corridor is devoid of any human habitation but is strongly influenced by villages along the periphery of the corridor.

General Information:

Landscape: Kangchenjunga Protected Area Type: Corridor
Established Year: 2007 Area: 149 sq. km.

Geographical Features:

Country: Bhutan
District(s): Haa and Paro

Average rainfall (m): Haa receives an average annual precipitation of 8 cm while Paro receives 13.2 cm.
Climate: Temperature ranges from approximated minimum of -3 degree celcius to maximum of 25 degree celcius in both the Haa and Paro valleys of the corridor. Relative humidity is very close to 82.5% valleys

Biodiversity Features:

Province: Himalayan Highlands
Biomes: Mixed mountain systems
Vegetation: Of the 14 classified ecosystem types, 10 are found within the corridor area. All ecosystems are characterized by their own specific vegetation types. They also vary in their area coverage such as the Temperate Moist Conifer Ecosystem has the largest area coverage followed by Temperate Scrub Forest Ecosystem and Sub alpine Temperate Conifer Ecosystem. Smallest area is covered by the Alpine Meadows and Grasslands Ecosystem.

Socioeconomic Features:

Community Structure: Among 14 villages in the two Geogs, Damthang, Chudiphu, Misis and Chunju lie close to corridor boundary. The household number is minimal and the houses are quite scattered. The inhabitants practice sedentary life through out the year without migration.
Natural Heritage:
Cultural Significance: A land tenure system called Tsamdrog or registered pasture lands exist which belong to the communities and monasteries. According to the locals, community pastureland are well managed compared to government owned natural pastureland
Livelihood strategies: Agriculture and livestock are the main source of livelihoods in the villages surrounding the corridros. Agriculture is predominantly subsistence, based on cereal and vegetable production. People are, in addition to farming, also engaged in pottering, labour, trade, carpentry etc.

Conservation Management:

Park Head Quarter:
Conservation History: Is an integral part of Bhutan Biological Conservation Complex. A corridor strategic plan (2008-2013) for better management of the corridor has been developed by the Nature Conservation Division, Ministry of Agriculture, Royal Government of Bhutan.
Conservation Challenges: Grazing pressure from Yak, Forest fire, Community dependence for timber, firewood constructional materials etc., poaching, reduction in herbivore population, Retaliatory killing, Crop damage by wildlife
Conservation Efforts: Eco-tourism, Micro-enterprise development (NTFPS, Yak products), Development of pasture
Transboundary Features: Illegal trade in Cordyceps and Musk pods across the border, Illegal felling of trees and collection of timber along the border areas
