Conclusion
The Western Ghats, is a biodiversity hotspot and the
greatest treasure of natural resources, serving humankind with
water and food security. It plays a major role in moderating
climatic and hydrological services for southern India. The
Western Ghats is the richest habitat of flora and faunal
species, and many protected areas were created to minimise the
anthropogenic influences. There are 15 National Parks, 47
Wildlife Sanctuaries, 6 Conservation Reserves, many reserve
forests and other protected areas. The two International
Biosphere Reserves are situated in this mountain range, which
shows the importance of the Western Ghats. The current study has
illustrated the diversity of flora and fauna in the protected
areas across the Western Ghats. As per the literature review of
525 articles, a maximum number of species are in the PAs of
Kerala and Silent Valley has the maximum number of species
diversity and endemism. Silent Valley National Park has 610
fauna species, of which 413 are endemic. Similarly, in the case
of flora, there are 652 flora species, including 151 endemic
species. Most of the threatened species were also found in the
Silent Valley National Park, 43 endemic fauna and 23 endemic
floras.
The maximum number of fauna and flora species is in Kerala
(2261 fauna and 3867 flora). Kerala State forms a significant
part of the southern Western Ghats and has the highest number of
PAs in the Western Ghats. Area covered by evergreen forest and
Shola forest are higher in Kerala with a variety of flora and
fauna species. Endemism in Kerala is 22.03% (flora fauna) and
4.81% as threatened species for the entire flora and fauna
species.
Conservation Measures
⦁ Restrict activities that lead to large scale land cover
changes and deforestation;
⦁ rehabilitate human settelements (located in core area) to
the better livable condition location with the infrastructure
and education facilities;
⦁ restore degraded forest patches with native plants;
⦁ restrict monoculture plantations and developmental
activites in protected areas;
⦁ involve local communities in forest conservation activites
;
⦁ awareness programmes- students and elders of effects of
deforestion; afforestation of degraded forest ;
⦁ reduce human-animal conflict by enriching animal corridor
with food and fodder species, restricting traffic through
protected areas etc.; and
⦁ regular monitoring through laest techniques camera trap,
etc.
