Amphibians in decline- the national and state scenario.
The Save our Frogs Campaign in Goa is gathering momentum
with support from all quarters and while nature lovers ecologists and concerned
citizens are joining hands with the Goa Forest Department to create awareness
and conserve Indian Bull frogs in particular and all other frog species in
general.
It is however important to look at the national scenario too
so that we realize the seriousness of the issues at hand concerning Amphibian
diversity and about the declining amphibian populations that are now in dire
straits.
According
to the IUCN Red List of Threatened species, at least 1,856 amphibian species
are threatened with extinction, representing 32 percent of all known species
worldwide
Scientists
fear that more than 50 amphibian species worldwide have already become extinct
over the last 15 years alone, which includes over 18 species from South Asia
alone.
This high rate of decline of amphibian species across the world provides an
indicator for the health of natural ecosystems in all regions and is a cause of
concern.
Currently
there are approx 427 species that are considered Critically Endangered (CR),
761 are Endangered (EN), and 668 species are Vulnerable (VU) worldwide. In
India an Assessment of Amphibians under the Conservation Assessment and
Management Plan (CAMP) workshop conducted by Biodiversity Conservation
Prioritization Project, India has listed 32 species as Critically Endangered,
71 species as Endangered, 52 species as Vulnerable and 9 species as Near
Threatened species. Over 63 species were listed as Data deficient as no
research data was available on them.
While
63 percent of Indian amphibians are endemic to India, i.e. found only in the
country 37 percent are considered non-endemics and are found across the world
besides the country. The Western Ghats is considered as one of the richest
areas of endemism as far as amphibian diversity is concerned followed by North
East India and Sri Lanka. Goa’s forests are part of the Western Ghats landscape
and the need of the hour is to conserve and protect these forests for amphibian
conservation.
Threats
for amphibian species in India include habitat destruction, fragmentation, and
agricultural practices like shifting cultivation, pollution, pesticides and
human consumption for meat. The laws that protect amphibian populations include
the Wildlife Protection Act, the Biodiversity Act and the Prevention of Cruelty
to Animals Act besides others.
The
Jerdon’s Bullfrog, poached for its meat in Goa is listed as Near Threatened
while the Indian Bull frog, another victim of large-scale hunting is listed as
Vulnerable. The Malabar Gliding Frog, an endemic species of South Asia found in
Mhadei Wildlife Sanctuary and the Mollem National Park is listed as a Near Threatened
species. Amongst other species found in Goa the Beddome’s Leaping frog is
listed as Vulnerable while the Jerdon’s Narrow mouthed frog is listed as Near
Threatened on a global scale.
The
need to intensify policing as well as create awareness amongst the masses of
the state as well as national scenario with regards to declining amphibian
populations is the need of the hour. It is now a known fact that these lesser
known life forms play an important role in every ecosystem and are key
indicators of monsoonal patterns, climate change and habitat quality besides a
host of other dynamics that influence our environment. It is important that we
thus aware that our survival depends on their survival and this is the only way
forward.
