04' and 28° 07' N and long. 88°
00' and 88° 55' E. Its terrain is hilly
with wide variation in altitude ranging from 300 m to 8583 m. The Teesta
is the main river of the state. Land use pattern of the state is given
in Table 3.23.a.
Average annual rainfall ranges between 210 mm to 2,500 mm. Temperature
in lower altitudes varies between 4.5° C
to 18.5° C.
The total population of the state is 0.4 million (1991 census) which
is mainly confined to the lower altitudes. The Scheduled Tribes constitutes

The recorded forest area is 265,000 ha constituting 37.34% of the geographic
area of the state. Reserved Forests constitutes 85.32%, Protected Forests
10.75% and Unclassed Forests 3.93%. Forests are distributed all over the
state. There are three forest types viz. Tropical Moist Deciduous, Himalayan
Moist Temperate, and Himalayan Dry Temperate Forests.
One National Park and 5 Wildlife Sanctuaries cover a total area of 0.20 million ha. It constitutes 28.88% of geographic area, which ranks it as the best covered state in respect to percentage of protected area.
3.23.4 Joint Forest Management
The resolution of Joint Forest Management in the state has been issued
in 1998. The total number of Village Forest Protection Committees are 98
and the area covered under the programme is 2,191 ha.
The JFM programme is extended to Khasmal/Goucharan areas and
degraded forest lands. The usufructuary benefit accruing from such management
is proposed to be shared between government and individual member by 75%
and 25% respectively.
The plan wise details of plantation are given in Table 3.23.b. The species-wise
plantation carried out by Forest Department are given in Table 3.23.c.

The forest cover of the state, based on satellite data of November 1998,
is 3,118 sq.km, which constitutes 43.94% of the geographic area. Dense
forest accounts for 2,363 sq.km. and open forest 755 sq.km. The forest
cover of the state is shown in Fig.3.22.
There has been a net decrease of 11 sq.km in the forest cover of the state
as compared to the previous assessment. The difference between the
data periods of the two assessment is about 4 years.
The change matrix, given in Table 3.23.d, reveals that there has been
an overall decrease of 60 sq. km. of dense forest. This is the result of
degradation of 49 sq. km. to open forest and 11 sq.km. to non forest. The
increase of 49 sq. km. of open forest is on account of conversion of 49
sq.km. of dense forest to open forest.

Note - Assessment of forest cover in VI cycle (1997) was carried
out visually on 1:250,000 scale whereas in the VII cycle (1999), it has
been done digitally on 1:50,000 scale. The total forest cover on 1:50,000
scale has been assessed as 3,002 sq.km. which comprises of 2,275 sq.km.
of dense forest and 727 sq.km. of open forest. Extent of scrub has been
assessed as 372 sq.km. For the purpose of comparison with 1997 assessment,
the above figures have been transformed to 1:250,000 scale (see section
2.2).
The loss of forest area is due to encroachment in east Sikkim whereas improvement is due to regeneration of Shorea robusta in South Sikkim and plantation of Cryptomeria japonica in west Sikkim.
