I -= e • ••~, , FOREST RESOURCES OF DHULIA DISTRICT OF MAHARASHTRA STATE FOREST SVBJ7'EY OF INIJI~t CENTRAL ZONE NAGPUR 1988 PRE l' l\ C Ii: This report contains the result of the inventory of the for"ests of Dhul ia district in Maharashtra, wade b~' the Central Zone (~f the Forest Survey of India. The inventory waS wade during the period November .1982 to March 1983. The report covers that part of the distr'ict which i:.> included in North Dhulia and West Dhulia Forest Divisions. P~rt of the district covered in Mewasi Forest Division was surveyed during 1977-79 and a report on the forest resources of this part was published earlif:r. The total forest area of Dhulia district ~s 4503 Sq.km., but this l~eport describes Uw situation of ~. about 3970 Sq. km. forest area which forror..; part of North & W~st Dhulia Forest Divisions. The total growing stock in the forests of 3 North & Y~est Forest Divis ions is about 3.38 x l~ m . The figure of average growing ~,;tock in one ·hectare of forest works out at 32.86 m3 . The three sp~cies which occur in preponderance are Anogeissus latifolia, Tectona grandis and Boswellia serrata. The three species account for near ly t .... VlO third of the growing stock. I About 40% of the populat.ion in the region covered by the inventory is that of t~e tribals who depend substantially on the forest for their livelihood, But unfortunately the forest resou~ce is fast dwindling on aocount of various biotic pressures. The forests have been depleted on accQuni; of shifting c;ultivation, enoroachments, uncontrolled grazing and frequent fires. Natural regeneration is either absent or inadequate. If immediate Gteps are not taken to prote(~t the forests from the biotio factor:; enumet'at.ed above total degradation of forests may take place. The staff of the Central Zone deserve commendations for their ~o~k, I hope the repor-t wi 11 be l"weful in plunning forest management in Dbul ia dist.rict.
