ABSTRACT
The farmlands of NWFP have about 80 million trees of
which two-third are in irrigated areas. The average
number of trees per ha is 46 for all areas, 72 in
irrigated areas and 27 in un-irrigated areas. Poplar
(24%), bakain (18%), Shisham (15%), ailanthus (13%) and
mulberry (10%) are the pre-dominant species in irrigated
areas. Ber (23%) and ailanthus (14%) are the most
common trees in un-irrigated areas. The tree stock is
mostly concentrated in lower diameter classes. The dia
classes 5-9, 10-14 and 15-19 account for 42%, 24% and
13% respectively of the total tree stock.The estimated
volume of gowning stock is 14 million m3 of which 10.6
million m3 (76%) is in irrigated areas.The per ha volume
of growing stock is 8.0 m3, 13.8 and 5.3 m3 for all
areas, irrigated and un-irrigated areas respectively.
The growing stock on irrigated areas is mainly
accounted for by Khajoor (27%) Shisham (19%) Mulbery
(13%), Poplar (12%). On un-irrigated areas, the growing
stock is accounted for by ailanthus (21%), Ber (15%),
mulberry and fig (9%) each.The farmers felled about 10.8
million tree (13.5% of the total trees stock) and
removed 2.9 million m 3 volume (21%of the total growing
stock) during 1989 to meet their own requirements and
for the purpose of sale.
