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 soilThe 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.
