Abstract

ABSTRACT The farmlands of the Punjab have about 200 million trees of which 95% are in irrigated areas. The number of tree per ha is 16.9 for all areas; 18.7 in irrigated and 6.2 in un-irrigated areas. Shisham (42%), Phulai (20%), Kiker (11%) Bakain (7%) and Mango (6%) are the main species in irrigated areas. Ber (31%) Phuli (20%), Kiker (19%) and Shisham (7%) are the predominant species in un-irrigated areas. Tree stock mostly consists of young trees. About 75% of all trees have diameter smaller then 24cm. The total estimated volume of growing stock is 46.6 million m3 of which 44.1 million m3 (95%) is in irrigated areas. The per ha volume of growing stock is 3.9 m3 for un-irrigated areas. The farmers felled about 14.8 million trees (7.4% of the total tree stock) and removed 9.4 million m3 of wood (20% of the total growing stock) from their farmlands during 1990-91 for meeting their own requirements and for the purpose of sale. The stumpage value of annual wood removals from farmlands is estimated at 5.7 billion rupees. The tree stock is equivalent to 0.73 million ha of plantation forests.
