Fine-scale genetic structure and gene flow in a semi-isolated population of a tropical tree, Shorea robusta Gaertn. (Dipterocarpaceae)
Sal (Shorea robusta) is a dominant tree species in the terai (southern flat lowland) of Nepal. It is common up to 1000 m. Sal is a deciduous species and attains height up to 45 m. It is the main source building timber and also used as fuelwood and fodder (Jackson, 1994).
Sal is a dominant tree species in the community forest of Terai. Sal forests occur at elevations up to 1500 m above sea level. With respect to its silvicultural characteristics, Sal has been described as the most gregarious and aggressive tree species of the forest (Troup 1921 cited in Sapkota et. al. 2009).
