| Abstract: |
The southern Western Ghats tropical montane cloud
forest sites (Gavi, Periyar, High wavys and Venniyar),
which are characterized by frequent or seasonal cloud
cover at the vegetation level, are considered one of the
most threatened ecosystems in India and the world.
Three out of four montane cloud forest sites studied in
the southern Western Ghats had experienced diminishing
trends of seasonal average and total rainfall, especially during summer monsoon season. The highest
level of reduction for summer monsoon season was
observed at Gavi rainforest station (>20 mm/14 years)
in Kerala followed by Venniyar (>20 mm/20 years)
site in Tamil Nadu. Average annual and total precipitation
increased during the study period irrespective
of the seasons over Periyar area, and the greatest
values were recorded for season 2 (>25 mm/28 years).
Positive trends for winter monsoon rainfall has been
observed for three stations (Periyar, High wavys and
Venniyar) except Gavi, and the trend was positive and
significant (90%) for Periyar and High wavys.
Increase in summer monsoon rainfall was observed
for Periyar site and the trend was found to be significant
(95%). |
