Basic information
Sample name: Jahlmanal (agroforestry system)

Reference: Y. S. Rawat, S. C. R. Vishvakarma, S. S. Oinam, and J. C. Kuniyal. 2010. Diversity, distribution and vegetation assessment in the Jahlmanal watershed in cold desert of the Lahaul valley, north-western Himalaya, India. iForest 3:65-71 [ER 2506]
Geography
Country: India

State: Himachal Pradesh


Coordinate: 32.57° N, 76.97° E
Coordinate basis: based on nearby landmark

Geography comments: "within the Lahaul division" and specifically in the "Jahlmanal watershed in the Lahaul valley... The watershed starts at the confluence of Jahlmanal and Chandra-Bhaga at an elevation of 2723 m asl in the south and end at 3600 m asl in the north"
coordinate based on Kardang

Environment
Habitat: temperate broadleaf/mixed forest

Altered habitat: plantation

Substrate: ground surface

WMT: 17.0

CMT: -7.0

MAP: 752.0

Habitat comments: climate data are for "The nearest meteorological station for the Jahlmanal watershed... at Tandi, 12 km far from Jahlma... at an altitude of 2846 m asl"
CMT and WMT estimated from Fig. 2

Methods
Life forms: trees

Sites: 10

Site area: 0.1

Sampling methods: quadrat

Sample size: 498 individuals

Size min: 5

Basal area: 12.054

Sampling comments: "Three transects were laid down starting from a base of the slope to the end of the vegetation zone in each selected site. The transects were 200 m apart from each other. The quadrats (10x10 m2) were laid down for tree and shrubs in a line running method (Kershaw 1973) along slopes with an interval of 10 m" (apparently meaning that there was one transect in this habitat consisting of 10 quadrats)
