FOREST RESOURCES OF RAIGARH DISTRICT OF MADHYA PRADESH LCkhCL*,:s.9~) -=-= ___...,. FOREST SURVEY OF INDIA. CENTRAL ZONE N.A.GPUR 1989 fOREST RESOURCES OF RAIGARH DISTRICT OF MADHYA PRADESH (~ VtVt~~·s~~l.\..) FOREST SURVEY OF INDIA CENTRAL ZONE NAGPUR 1989 India's forest wealth is diminishing very fast due to the pressures of population. It has become necessary to have an accurate picture of the remaining resources and therefore. Central Zone of Forest Survey of India carried out inventory of forest resources of Raigarh district of M~lhya . Pradesh during March to June, 1985. This report is essentil~lly based on the data collected during the survey. It covers two forest divisions in Raigarh district namely Raigarh forest division and Jashpur forest division. These forests formed a part of former princely states of Raigarh. Udaipur, Sarangarh and Jashpur. These forests suffered badly during the long period under princely rule due to lack of scientific forest management and proper protection. These conditions have changed now and systematic forest management has been introduced in these areas after merger of the princely states and there is considerable improvement in forest stock during the last decade as revealed from the survey done by us in 1985 and the one done by the State forest department in 1975-77. On the basis of the inventory carried out by us the tota1 growing stock in the district is approximately 2.926 x 10 6 cu.m. which works out to 60.098 cU.m. per hectare for 4868.39 sq.km. vegetated area of the district. Sal contributes nearly 46% of the total growing stock. Raigarh district has bamboos over 1020.96 sq.km. occurring along with other trees. Total growing stock 7 of the bamboos was found to be 118810 tonnes (3.412 x 10) which works out to 116.37 tonnes per hectare. Though the results of the survey conducted in 1975 and the one conducted after a decade in 1985 are not strictly comparable on account of 1975 survey being confined to 4008 sq.km. of area and 1985 survey over the entire forest area of 6029 Sq.krn., there appears to be considerable improvement in the growing stock of both the· trees and the bamboos in one decade. According to the 1975 survey per hectare volume of trees was only 40.926 cU.m. as against 60.098 6cu.m.in 1985.Total growing stock7 of bamboos was 7.396 x 10 culms as compared to 3.412 x 10 culms in 1985. This is surely a good sign and the credit for such improvement goes to the Madhya Pradesh forest department for ensuring scientific management of these areas once these came under their control. / This report has been campi led by Sarvashri M.D.Singh S.T.A. and Anil Biala J.T.A under guidance of Shri S.C.Gupta, Joint Diredtor, Forest Survey o~ India, Central Zone, Nagpur. Their work is appreciated. 'r hope that ·this report '{Quld be of 'use to all 'who have interest in forest resources of the country in general and of Raigarh district of Madhya Pradesh in p~rticular.
