Abstract:
The farmlands of the Punjab have about 200 million trees of which 95% are in irrigated areas. The number of trees 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%), phulai (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 di4meter smaller than 24c1n. The total estimated volume of growing stock is 46. 6 million m'' of whiqh 44. 1 million m (95/0) is in irrigated areas. The pqr ha volume of growing stock is 3. 9 m for all areas, 4. 4 m for irrigated areas and 1. 4 m 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.
