Nokrek
Biosphere
Reserve
is located
in the
Garo Hills
district
2 kms
from Tura
Peak.
The reserve
is one
of the
least
disturbed
forest
tracts
of the
sub-himalayan
ranges.
It is
the first
biosphere
reserve
of its
kind in
the northeast
region.
The Garo
Hills
contain
many natural
limestone
caves.
The famous
Siju Cave
is located
very close
to the
Nophak
Lake near
the Simsang
River
game reserve.
The Cave
is filled
with water
and is
miles
long.
Geology,
rock and
soil
The
entire
Biosphere
Reserve
is hilly.
The rock
is mainly
gneisses,
granulites,
migmatites,
amphibolites
and banded
iron formation,
intruded
by basis
and ultra-basic
bodies.
In most
of the
Biosphere
Reserve
area the
soil is
red loam.
But sometimes
it varies
from clayey
to sandy
loam.
The soils
in the
Biosphere
Reserve
are rich
in organic
matter
and nitrogen
but deficient
in phosphate
and potash.
The area
consists
of patchy
sedimentary
rock comprising
of pebble
bed, sand
stone
and carbonaceous
shales.
Fauna
Nokrek
Biosphere
Reserve
supports
a wide
variety
of animals.
There
is a great
diversity
of animal
species
like mammals,
reptiles,
avi-fauna
and invertebrate
groups.
Detailed
scientific
study
on fauna
is lacking.
