ENP emerges as a thriving habitat for endangered frog

 

The Hindu Bureau, 

IDUKKI, September 10, 2026

A recent comprehensive amphibian and reptile survey across the protected areas of the Munnar Wildlife Division found that Eravikulam National Park (ENP) near Munnar in Idukki has emerged as a thriving habitat for the endangered Resplendent Shrub Frog, a species acutely vulnerable to climate change. According to officials, the survey recorded a healthy population of the frog, which is endemic to the Munnar region.

Herpetologist Sandeep Das said that over 1,938 Resplendent Shrub Frog encounters were recorded in ENP during the survey. “The healthy population of this frog emphasises that this habitat represents the final survival stronghold for the species,” said Dr. Das. “The frog was first found in Anamudi and later in the grasslands of Meesapulimala and Eravikulam National Park. Normally, cold-climate-adapted frogs move to higher elevations as temperatures rise. But these frogs already live at the highest elevations, and these areas are their only habitat. Destroying these habitats would lead to their extinction.”

He added that the robust population highlights the urgent need to protect the high-altitude grasslands across ENP and greater Munnar.

Eco-restoration projects

The survey also highlighted the success of eco-restoration projects conducted in the Shola National Parks, which have led to the return of several native species. Munnar Wildlife Warden K.V. Harikrishnan noted that restoring grassland habitats has driven a notable comeback of species such as the Anamalai Spiny Lizard, Kodaikanal Bush Frog, and Shola Night Frog, serving as a compelling indicator of ecological recovery.

The four-day survey ran from September 3 to 6 across protected areas under the Munnar Wildlife Division, including Eravikulam, Anamudi Shola, Pampadum Shola, and Mathikettan Shola National Parks, as well as the Kurinjimala Sanctuary.

In total, researchers documented 54 amphibian and 52 reptile species. “According to the IUCN Red List, 19 species categorised as endangered — such as the Resplendent Shrub Frog, Yellow-eyed Reed Frog, Anamalai Gliding Frog, Toad-skinned Leaping Frog, and Shola Night Frog — were recorded during this survey, along with 10 vulnerable species (like the Galaxy Frog) and seven near threatened species (such as the Purple Frog),” said ENP Assistant Wildlife Warden Nizam.

A Centre-State ‘rice deal’ that secured the shelter of Nilgiri tahrs in Munnar

 

SANDEEP VELLARAM, 

IDUKKI, the hindu, april 1 2025

Fifty years ago, the Eravikulam National Park (ENP), the pristine habitat of the Nilgiri tahr in Munnar, was almost lost to land redistribution. But an unusual backroom deal, sealed over wagons of rice, changed its fate forever.

On March 31, the park celebrated the golden jubilee of its declaration as the Eravikulam-Rajamala Wildlife Sanctuary. It was after a silent movement by a group of people that Eravikulam was declared a protected area. The sanctuary was created in 1975 to protect the Nilgiri tahr and it was named ENP in 1978.

According to records, around 1975, the government decided to give land to landless people. But the then Kanan Devan Hills Plantations managers J.C. Godsbery, Samar Singh and K.N. Chenkappa intervened and called Union government Secretary M.K. Ranjith Sinh to Munnar. After the visit, Mr. Sinh submitted a report to Prime Minister Indira Gandhi.

In his book A Life with Wildlife – From Princely India to Present, Mr. Sinh said, “Indira Gandhi wrote a letter to the then Kerala Chief Minister C. Achutha Menon requesting him to declare the area a national park. The matter, however, was in limbo, with the State government remaining indecisive for fear of a political fallout.”

The book further describes how a rice deal resulted in the declaration of the park. “Minister of State for Food Anna Shaheb Shinde temporarily assumed additional responsibility for the portfolio of Forests and Wildlife. One day, he asked me if any forest-related issues were pending in Kerala and told me that Kerala Minister Baby John was arriving for a meeting. I told him about the Eravikulam issue and he asked me to join the meeting,” said the book.

40 wagons of rice

“During the meeting, Baby John informed him about the shortage of rice in Kerala and sought 40 rail wagons of rice. With a disarming smile, Shinde offered 25 wagons of rice and enquired about the national park declaration. Baby John, returning the smile, said that the State was actively considering the declaration... In the end, 36 wagons of rice were agreed upon in exchange for the protection of the sanctuary... Today, this exchange resembles a fanciful tale. But it did happen,” narrated the book.

Cold spell worries for Eravikulam park

Giji K. Raman, Idukki
The Hindu, January, 13, 2019 

The cold wave that began on January 1 has not only affected tea plantations in Munnar but also the grasslands of the Eravikulam National Park (ENP), the natural habitat of the Nilgiri tahr.
The upper reaches of Munnar have been experiencing temperatures below 00 C since the start of the month, which is unusual, and mercury dropped to -40 C after a decade in the region. Munnar Wildlife Warden Lakshmi R. told The Hindu on Saturday that vast areas of grasslands in the ENP had dried up.
She said it was a matter of concern as the area would turn fire-prone well before the drought season. She said Pampadumchola was experiencing sub-zero temperature continuously and mercury dropped to -40 C there.

Widespread damage

“Normally, temperature will rise after one or two days and the damage to the flora will be limited. However, this time the damage is widespread,” she said adding a field study would be conducted to analyse the effect of climate change in the region. Rajamala, one of the main areas where neelakurinji blossomed last year after 12 years, was inside the ENP. The August floods had damaged buds and flowers and its effect would also be studied, she added.
The germination period of neelakurinji had just started and it was being analysed to learn the effect of the floods on the flora. The changes in climate conditions were clearly evident in the Western Ghats as its eastern side formed part of rain shadow areas.
Ms. Lakshmi said controlled burning had already been done on 600 hectares of grasslands and new tender grass appeared with the winter season. It might not immediately cause any shortage of fodder for the fauna, including the Nilgiri tahr, she said. However, a drought situation much before the advent of the summer season raised concerns of wildfires. If the situation continued, fodder could be in short supply too, she added.
The changes in the climatic conditions and its effect on the flora and fauna would be studied and recorded for management purposes, she added.

Counting Munnar’s winged beauties

Radhakrishnan Kuttoor
Pathanamthitta, 
The Hindu, September 23, 2015

The Kerala Forest and Wildlife Department is to launch the first-ever comprehensive and scientific survey of butterflies in the Munnar landscape soon. The three-day survey will commence on Thursday, according to G. Prasad, wildlife warden at Munnar.

Mr. Prasad says the area is characterised by a wide variety of habitat, starting from the low-lying dry scrub jungles of the Chinnar wildlife sanctuary to the ascending peaks with shola forests in the four adjoining shola national parks and the Eravikulam National Park with vast spreads of grasslands.

There is also a wide gradient of altitude, temperature, and vegetation, which all put a lepidopteran enthusiast in great excitement.

The survey

As many as 60 butterfly enthusiasts, including Kalesh Sadasivan of the Travancore Natural History Society and B. Sreekumar and Toms Augastine of the Kottayam Nature Society, will be participating in the butterfly survey, says Mr. Prasad.

E. Kunhikrishnan, senior wildlife biologist, will be the programme coordinator and Mr. Prasad will lead the survey to be held at the Chinnar wildlife sanctuary as well as the four national parks of Mathikettan shola, Pampadum shola, Anamudy shola, and the Kurinjimala wildlife sanctuary. All the four shola national parks and the Chinnar wildlife sanctuary will be systematically surveyed by establishing 14 strategic base-camps covering all the elevations and habitats. The data will be gathered using structured checklists and data sheets and critically analysed with GPS readings, says Mr. Prasad.

Butterfly calendar

For the first time in the world, the Wildlife division at Munnar has made attempts to prepare a butterfly calendar for the Chinnar wildlife sanctuary this year, he says. So far, as many as 208 butterfly species, including 58 new species, have been identified in the Chinnar wildlife sanctuary alone, he says.

Nilgiri Clouded Yellow, Nilgiri Fritillary, Palni Four-ring — all rare and endemic to the Western Ghats, Davisons Bush Brown and Red Disk Bush Brown, which are endemic to the Southern Ghats, are a few of the rare butterfly species identified in Chinnar.

The survey results are expected to be published during the Wildlife Week celebrations to be held from October 2 to 8.

Nilgiri tahr population in new pockets

K.S. Sudhi, KOCHI,  
The Hindu, September 4, 2015

Nilgiri tahr populations have been recorded from 17 hitherto unrecorded pockets across Kerala and Tamil Nadu, according to a non-governmental organisation. This is the only species of mountain ungulates that exists in southern India.

It was during a four-year-long survey, organised by the WWF and forest officials, that its presence in new and small pockets was identified. The mountain goats, endemic to the Western Ghats regions of Kerala and Tamil Nadu, numbering 131 individuals, were counted, according to the WWF.

In Kerala, the populations were confirmed at nine locations, including Pathrakadavu, Atumudi, Koomban, Madumudi, and Chokramudi. The eight locations in Tamil Nadu included Nagamalai, Marakkal Malai, and Vasakku Malai.

The total population of the species in the region was estimated at 3,122. The single largest population of the species is in the Eravikulam National Park in Kerala. Though many unknown populations were believed to exist in small pockets throughout its range, they had not been surveyed due to the rugged and inaccessible terrain. Inclement weather also limited the understanding of the status and the distribution of the tahr across its range, according to the report.

The population status and distribution of the tahr across its entire distribution range were observed for four years from 2008The population of the species is believed to be declining due to “uncontrolled hunting, conflict with livestock grazing, and habitat loss,” according to the report, which will be released shortly.

The field surveys were carried out by Paul Peter Predit and Varun Prasath.

Eravikulam grasslands at risk from invasive plants

Giji K. Raman
KATTAPPANA,  
The Hindu, November 8, 2014 

The grasslands of the Eravikulam National Park are under threat from two invasive alien plants.

Eagle fern and goatweed, native to California and Brazil, respectively, have spread across the grasslands, damaging the park’s flora and posing a threat to herbivores, especially the Nilgiri tahr, say recent studies.

The studies are a prelude to documenting the main aggressive plants of the State.

Eagle fern ( Pteridium aquilinum ), also known as bracken, is a large fern that grows to over three ft and readily colonises areas, hampering the growth of grasses and other plants. On the underside of the leaves is sori, which produces spores that, like seed, travel in the wind and create new colonies.

Goatweed ( Ageratum conyzoides ), known as Murianpacha locally, is a flowering plant that grows up to 80 cm.

“Both the plants are unpalatable to herbivores and make colonies, are highly invasive, and prevent the growth of grasses and other plants,” says T.V. Sajeev, Head, Department of Entomology, Kerala Forest Research Institute, Peechi.

He says these plants have spread wide and could be hindering the growth of fodder for wild animals, especially the Nilgiri tahr.

Eagle fern is allelopathic, that is it lets out chemicals that keep other plants from growing. Because of the chemical effect, animals do not feed on its leaves.

The plant contains carcinogenic agents, and is a threat to human beings and animals.

K.G. Ashok Kumar, who led a team to document the two plants as part of the Save Biodiversity Campaign, told The Hindu that eagle fern was heavily distributed in the low-lying areas of the park and posed a bigger threat than expected.

The plant could replace natural vegetation, and once it spread was difficult to control.

He said the dry leaves of the eagle fern caught fire readily, and the ashes facilitated the growth of the plant.

Mr. Ashok Kumar said the two plants were dangerous to animals and human beings, and it would be a huge challenge for the authorities to control them.

Murianpacha, he said, was also found in parts of Kottayam, Kollam, Pathanamthitta, Palakkad, and Wayanad districts, and could grow in different soil types.
