Growth, Survival and Mean Annual Increment of <I>Quercus leucotrichophora</I> (ban Oak) on Degraded Lands of Doon Valley

Abstract

Quercus leucotrichophora (Ban Oak), is a most suitable tree species for protective and productive purpose in the degraded lands of higher altitude of North-West Himalayan region. An attempt has been made to explore the possibility of its growing in the lower altitude i.e. in the degraded lands of Doon Valley so that its large scale plantation can be taken up where soil and water conservation measures are to be carried out on priority basis. On the basis of survival, height, collar diameter and diameter at breast height performance from 1986 to 1994, it is possible to grow it on degraded lands of Doon Valley. Moreover, its growth performance in degraded lands are quite encohraging. The regression equations between plant age with individual growth character (i.e. height or collar diameter or diameter at breast height) were also estimated.
