ABSTRACT
The present investigation was carried out during 2011-2014 in Sirmour district of Himachal Pradesh,
located between 30° 38’40” to 31° 01’14” N latitude and 77° 01’ 5” to 77° 26’ 13”E longitude, at an elevation
ranging from 500 m to 3500 m a.s.l. to develop comprehensive forest resource database and spatial analysis of
growing stock and evaluation of forest for normality for Rajgarh forest division. The necessary data such as
paper maps and inventory report was acquired from the Divisional office of Rajgarh Forest Division to create
comprehensive database and necessary thematic maps were prepared. For estimation of volume and carbon
inventory data was analysed in geographical information system (Arc.GIS).There are six working circles, four
ranges, 879 compartments and 41 beats. Small to very small variation in area of different management units,
forest vegetation and land uses were observed as compared to area reported in Working Plan. Out of total
growing stock and carbon stock of 7.05×10
6
m
3
and 3.29×10
6
t, respectively, in the Division the Habban, Rajgarh,
Narag and Sarahan range accounted 71.98 % and 67.85 %, 19.72 % and 22.59 %, 4.03 % and 5.06 %, & 4.27 % and
4.50 %, respectively for the total growing stock and carbon stock, respectively. Among different working circle, Chil
Shelterwood, Deodar-Kail, Rehabilitation, Plantation, Protection and Selection accounted 8.98 % and 9.15 %, 31.37 %
and 28.44 %, 6.45 % and 7.73 %, 2.47 % and 2.57 %, 15.13 % and 21.66 %, 35.59 % and 30.45 % for total growing
stock and carbon stock , respectively . The status of Chil Shelterwood working circle was as: growing stock (251.37
m
3
ha
-1
), tree total biomass (199.46 t ha
-1
), tree total carbon stock (99.73 t ha
-1
), tree total carbon mitigated
(366.47 t ha
-1
), regeneration per cent (40.90%). However the status of Deodar-Kail working circle was as:
growing stock (463.35 cu m/ha), tree total biomass (436.12 t ha
-1
), tree total carbon stock (218.06 t ha
-1
), tree
total carbon mitigated (799.56 t ha
-1
) and regeneration per cent (65.28 %). The status of growing stock and
biomass carbon in Rehabilitation working circle was as: growing stock (103.56 m
3
ha
-1
), tree total biomass
(120.74 t ha
-1
), tree total carbon stock (60.37 t ha
-1
), tree total carbon mitigated (221.35 t ha
-1
) and regeneration
per cent (24.17 %). The growing stock (92.30 m
3
ha
-1
), tree total biomass (127.86 t ha
-1
), tree total carbon stock
(63.93 t ha
-1
), tree total carbon mitigated (234.40 t ha
-1
), regeneration per cent (27.50 %) was present in
Plantation working circle. The status of Protection working circle was as: growing stock (289.96 m
3
ha
-1
), tree
total biomass (701.55 t ha
-1
), tree total carbon stock (350.77 t ha
-1
), tree total carbon mitigated (1286.17 t ha
-1
),
regeneration per cent (58.61 %). In Selection working circle, the status was as: growing stock (611.95 m
3
ha
-1
),
tree total biomass (466.30 t ha
-1
), tree total carbon stock (233.15 t ha
-1
), tree total carbon mitigated (854.88 t ha
-1
), regeneration per cent (32.50 %). The forest under Chil Shelterwood and Selection working circles were
overstocked, with poor incremental growth and poorly regenerated. However in Deodar-Kail working circle the
forest was under-stocked with poor incremental growth and regeneration. In rest of the working circles i.e.
Rehabilitation, Plantation and Protection, the distribution of stem volume in diameter classes was
disproportionate and regeneration was very poor. In general forests of Rajgarh Forest Division do not meet the
criteria of normal forests.
