The Jeypore ground gecko (Geckoella jeyporensis) was first noted
and described by a British colonel in 1877, but was not seen again for more
than 130 years, and presumed extinct. Enter a team of committed scientists, who
scoured the northern hills of India’s Eastern Ghats mountain range in the hope
of discovering a specimen.
Armed with only the brief notes
of amateur naturalist Colonel Richard Henry Beddome, the team’s search paid off
in 2010 and again in 2011, when they discovered the strikingly beautiful ground
gecko in two locations.
Ishan Agarwal led the project. He
was conducting PhD research on Indian bent-toed geckos (Cyrtodactylus) at the
time, which include Geckoella, a genus of Gekkonidae found only in India and
Sri Lanka.
“It turns out that most of these
are undescribed species with very small ranges, and many require conservation
attention,” Agarwal told Mongabay.com. “All
the [Geckoella] are relatively common, while G. jeyporensis had not been recorded since its original sighting
and description.
“Its unique morphology and the
fact that it wasn’t known apart from a single specimen motivated my search. G. Jeyporensis is unique in its dorsal
scalation as well as phylogenetic position. (Morphology is the study of an
organism’s structure, while phylogeny refers to an organism’s evolution or
development.) “All other Indian species are complexes, while G. jeyporensis is a relict lineage found
only in high elevations of the Eastern Ghats.”
The Jeypore ground gecko’s new
lease on life was brief, however. It was quickly listed as Critically
Endangered by the IUCN due to severe threats to its habitat.
A tiny range, multiple threats
The gecko’s range is small —
estimated at just 20 square kilometers (7.7 square miles), between elevations
of 1200 and 1300 meters (roughly 3,900 to 4,265 feet). The exact locale has
been kept secret to prevent poachers hunting the gecko back into extinction.
But the general locations are to be found in two neighboring states: Andhra
Pradesh (near Galikonda), and Odisha (near the species’ namesake Jeypore).
“The high elevation forests at
Galikonda are highly degraded, and have been extensively converted to coffee
plantations, only some of which have native shade trees,” Agarwal and his team
wrote in their 2013 article announcing the rediscovery. “The plantations do not
seem well maintained, and there are small patches of native vegetation toward
the fringes and near streams. At Deomali [near Jeypore], high elevation forests
are restricted to pockets in depressions and sheltered areas, and have stunted
trees, rich leaf litter and epiphytic growth.
“The forest habitats in which Geckoella jeyporensis was found are
under extreme anthropogenic pressures. Neither area in which the new material
was collected is formally protected and both have been severely deforested.
Galikonda and the surrounding hills have also been extensively converted to
coffee plantations, while Deomali faces grazing and fuel wood collection
pressures. More broadly, the hills in Koraput District face pressures from
mining as well as social forestry activities.”
Agarwal included a strong warning
in his paper regarding the Jeypore gecko’s future: “Even if it is widely
distributed in the region, the potential habitat available to G. jeyporensis
may be restricted by its presumed habitat preference,” he wrote. “Deomali and Galikonda,
the only localities from where Geckoella
jeyporensis is definitely known, require immediate protection and surveys
in the region are needed to determine where else [it] occurs.”
Farida Tampla, World Wide Fund
for Nature (WWF) India state director for Telangana, cites further risks to the
Jeypore gecko and its habitat co-inhabitants: “The main threats facing the
Eastern Ghats include deforestation, hydropower projects, bauxite mining and
road widening,” she told Mongabay. In addition, “massive impoundments that dams
and their reservoirs have formed between the Andhra Pradesh and Odisha borders
have submerged thousands of hectares of forests and [are] turning hilltops into
island[s] and thereby isolating wild species.”
Reptiles at risk
The Jeypore gecko isn’t alone in
its plight; 19 percent of the world’s reptiles face extinction due to habitat
loss and over-harvesting according to a recent study by the Zoological Society
of London and the IUCN’s Species Survival Commission. Additionally, global reptilian
biodiversity has fallen by 58 percent since 1970, according to WWF’s
International’s bi-annual Living Planet Index 2016.
Lead author Monika Böhm notes a
specific reason for these precipitous population drops: terrestrial reptiles
are often restricted to limited localities due to their specialized biological
and environmental requirements; they also aren’t very mobile, making them
particularly vulnerable to habitat degradation.
Böhm adds that, “Reptiles are
often associated with extreme habitats and tough environmental conditions, so
it is easy to assume that they will be fine in our changing world.” But that
isn’t the case.
WWF director general Marco
Lambertini sees this rapid decline in reptile biodiversity as a strong warning
sign of a planet in peril. “The ecological footprint — which measures our use
of goods and services generated by nature — indicates that we’re consuming as
if we had 1.6 Earths at our disposal,” he said. “Lose biodiversity and the
natural world, including the life support systems as we know them, will
collapse.”
A precarious tomorrow
The recently rediscovered Jeypore
ground gecko’s future is bound up with that of modern India; a nation of 1.3
billion people driven hard by the development-friendly policies of Prime
Minister Narendra Modi. India remains a land of divisive contrasts, where
progressive government plans to protect large swathes of habitat can as quickly
be overturned by new government economic development plans, and/or undermined
by lax law enforcement and corruption.
Sharing many floral and faunal
elements with sister ghats to the west, the Eastern Ghats’ uniqueness and
biological vitality are often overlooked. The Eastern Ghats are fragmented,
divided by four major rivers, while the celebrated Western Ghats — regarded as
one of the jewels in India’s natural crown — consist of an almost unbroken
mountain landscape.
WWF’s Tampal said that the 1986
rediscovery of the Indian golden gecko (Calodactylodes
aureus), followed by the Jeypore ground gecko’s more recent scientific
resurrection, caused some resurgence of public interest in protecting the
Eastern Ghats.
But a geopolitical realignment
has generated a major conservation setback, Tampal explained. Andhra Pradesh’s
division into two states in 2014 — Telangana is a break-away — means that the
Andhra Pradesh government is now trying to economically “catch up speed”, and
will be eyeing protected areas in the Eastern Ghats to meet its land,
irrigation and mining needs, Tampal says. That spells more development pressures
for the already besieged Eastern Ghats.
“Several researchers have begun
to study the faunal diversity of this incredible region, but the
[anthropogenic] threats… seem to loom larger,” Tampal said.
As go the Eastern Ghats, so go
the geckos
The Eastern Ghats and their
dependent species are at equal risk if escalating development continues
unchecked — representing a looming loss for scientists. “The ghats are [yet] to
be completely understood in terms of [their] biodiversity, and losing this
[habitat] to rapid development will be a huge loss to the country’s natural
heritage, and with it some of the endemic species found nowhere else in the
world,” Tampal said.
In a 2000 paper, Madireddi V.
Subba Rao warned of the dire future facing the Eastern Ghats should there be no
intervention by conservationists. The former Andhra University Department of
Environmental Sciences chair was especially alarmed at the rate of
fragmentation in recognized reptile habitats.
To counter this degradation,
Subba Rao wrote, “habitat restoration needs to be a vital component of forest
management programs to improve reptile habitat, help ensure a balanced
ecosystem, conserve natural flora and fauna and serve as a model for other
regions”.
Agarwal worries that if no
proactive conservation plan is put in place soon for the Jeypore ground gecko,
it will face a tough climb back from the brink of extinction: “[T]here is no
understanding of its ecology and distribution, and it is likely that the
species will not persist indefinitely in these marginal habitats.”
The future is uncertain for the
Golden gecko as well. Long considered extinct, it was rediscovered in 1986.
Though now categorized as a species of Least Concern, the IUCN notes that its
habitat faces several site-specific threats. Zoologists argue that the Golden
gecko’s conservation status needs to be revisited, as its existence is under
threat from new development projects.
Urgent need to create “gecko
reserves”
Agarwal argues that official
habitat protection is needed now to ensure the survival of the region’s unique
geckos. And there are precedents for such protections: the Indian Forest Act
allows central and state governments to designate natureland as “reserve
forests” (as a tiger reserve, for example), or as “protected forests,” which
either restrict or limit activities permitted within their boundaries. These
protection orders can easily be overturned, however, as seen in the case of the
Ken-Betwa River Link project and the proposed destruction of the Panna Tiger
Reserve.
Tampal urges a public private
conservation partnership: central and state governments, industries and local
communities have an equal stake in, and are equally responsible for, ensuring
the protection of the Eastern Ghats, with its unique mountain chain and endemic
animal inhabitants.
She noted that the Andhra Pradesh
government has moved swiftly in the past to designate protection areas for more
charismatic fauna. “Protection of environment, forest and wildlife is enshrined
in the Constitution of India and the government will have to continue to be the
main player in species protection,” Tampal said. “However, the focus will need
to not only be on the larger and well-known animals. Even the lesser-known
animals are under greater threat, and the government will have to put together
species recovery plans for many of these species.
“People, especially those living
close to wildlife, have always been an important constituency in the protection
of wildlife,” she added. “They will need to be incentivized to ensure that they
continue to be equal partners in protection, and at the same time ensuring that
these forest people are also able to live a life of dignity and self-respect.”
Avoiding gecko Armageddon
Despite the many challenges,
Agarwal has some optimism for the future of the Jeypore ground gecko and for
the Eastern Ghats, suggesting that if the reserve forests where G. jeyporensis now resides remain
forest, then there is hope.
“The good thing is the species is
also found in degraded habitats and coffee plantations,” he explained. “If key
reserve forest areas are protected, and some simple measures followed in coffee
plantations, it is likely we can save this species.”
WWF India CEO Ravi Singh
emphasized that the gecko’s local problem has a global and national source:
that unless the world’s and India’s consumption patterns are examined and
sustainable agricultural practices adopted to decrease the anthropogenic impact
on the planet’s biodiversity, then many species, including the gecko, will be
lost.
Tampal is more blunt: “It is the
more privileged, and those living in the city, who will need to be shaken out
of their inertia, to become less consumerist and bring about a change in their
lifestyle, be less wasteful of resources and to contribute to species
protection.” But how to remind coffee drinkers each time they sip a cup of the
caffeinated Indian brew that geckos are threatened by the habit?
Local advocacy is critical too,
which is where scientists like Varad Giri come into the picture. An unsung hero
of conservation, according to Sanctuary Asia, which bestowed a Wildlife Service
Award on him last year, Giri was a member of the team that rediscovered the
Jeypore ground gecko in 2010.
“Giri is pushing the boundaries
of science, and filling the cavernous gaps in our knowledge of India’s ‘less
charismatic’ species,” Sanctuary Asia wrote. “This enables us to formulate
effective conservation strategies. He was especially praised for his ability to
spread enthusiasm for conservation and a willingness to share knowledge with a
new generation of researchers.
“Highly skilled and regarded, he
prefers to work in the background and is little known to the public, though
people involved with the study and conservation of amphibians and reptiles are
in awe of his achievements, and for them he is already something of a
celebrity.”
Without committed local
conservationists like Giri, along with global champions, the Jeypore ground
gecko and its reptilian cousins — found only in the Eastern Ghats — will surely
face a quiet extinction.
