Phase I: (20,000-16,000 yrs B.P.) - It records lhe existence of grassland as it is
evidenced by high frequency ofPoaceae alongwith herbs and ferns depicting cold and dry
climatic regime.
Phase 1/: (16,000-4,000 yrs B.P.) - It records emergence of such herbaceous taxa
which are lhe associates of Shola forest on one hand and reduction of grasses on the olher.
This shift in lhe vegetation has revealed the climatic amelioration leading to warm and
humid climate.

of lhe family My,taceae); Lonicera and Olea (one species each Oleaceae); Xanthophyllum
(one species Polygalaceae); Zizyphus (one species Rhamnaceae); Carellia (one species
Rhizophoraceae); Adina, Canthiun, Coffea and Morinda (five species Rubiaceae) has
been studied.

Depositional environment and climate during the Quaternary
Period in the Himalaya: a palynological approach
To build up a fine resolution climatic sequence of Quaternary
Period in the Himalayafl region
Pollen analysis of four surface samples from Dewar Tal, Garhwal Himalaya has
revealed lhe dominance of arboreals over non-arboreals. Amongst lhe arboreals Pinus followed
by Quercus and Alnus are lhe major representatives, whereas Salix, Myrica, Rhododendron,
Acer, Bauhiflia together with sluubby elements of Strobilaflthes, Rosaceae and
Oleaceae are sporadic. The ground vegetation comprises mainly grasses, sedges, Cheno/
Ams, Asteraceae, Polygonum, etc. Fern spores are quite frequent in most of the samples.
n,e recent pollen spectra constructed from Dewar Tal show a close coherence with lhe
modern vegetation composition in the region.
