T.N. Forest Dept. restores unused stretch of intertidal barren land along Uppanar River in Cuddalore
For years, the revenue land owned by the Kudikadu panchayat near Cuddalore SIPCOT remained an unused stretch of intertidal barren land with degraded creek edges and suffered from neglect due to growth of invasive species. The land was selected for the restoration process since it comprised low-lying, saline-prone areas with natural tidal influence, making it ecologically ideal for mangrove regeneration.
An assessment of the site was conducted and the Forest department initiated restoration efforts by planting appropriate species of mangroves based on the region's salinity and tidal conditions.
According to B. Iqbal, Forest Range Officer (FRO), Pichavaram Range, 'The invasive species of Prosporis juliflora was removed and a modified fish-bone canal system was developed to facilitate natural tidal flow and sapling survival across a total expanse of 25 hectares.'
'In addition, linear planting of native mangrove species was carried out along the canal and creek edges, with a total of 20,000 saplings. Key mangrove species, including Rhizophora mucronata, Avicennia marina, Exocoeria agallocha, Bruguiera cylindrical, Ceriops decandra, Kandelia candel, and Soneratia apetala were planted along the stretch. The entire plantation and their maintenance is being carried out by the local communities, ensuring community livelihood generation and stewardship,' he added.
The fish bone model allows the water to reach every nook and corner of the field channels. This model has found success in earlier applications at Pichavaram.
Considering the ecological significance and long-term conservation potential of this site, a formal proposal has been submitted under Section 26 of the Tamil Nadu Forest Act, 1882, to notify this area as Reserve Forest. This would ensure long-term legal protection to the restored mangrove ecosystem.
According to government estimates, the mangrove cover in Tamil Nadu is at 44.94 square kilometres (sq. km.), out of which 7.73 sq. km. is in Cuddalore. Straddling the Vellar and Coleroon estuaries, about 21% of Pichavaram is occupied by waterbodies, 27% by healthy mangrove vegetation, 38% by mudflats with sparsely grown mangroves, and sand dunes occupied the rest of the area.
According to Mr. Iqbal, to further strengthen local participation and protective mechanisms, steps have been initiated to form a Village Mangrove Committee (VMC) at Kudikadu. This committee will involve local stakeholders in protection, maintenance, and awareness activities related to the mangrove ecosystem.

In Conservation Win, Tamil Nadu State Animal Nilgiri Tahr's Numbers Shoot Up
Chennai: In a major conservation success story from the Western Ghats, the endangered Nilgiri Tahr - Tamil Nadu's state animal - has shown a significant rise in numbers. The Second Synchronized Survey of Nilgiri Tahr conducted in April 2025 has estimated 2,655 individuals across Tamil Nadu and Kerala - a substantial increase from the 2024 estimate of 2,383. Led by the Tamil Nadu Forest Department under the ambitious Project Nilgiri Tahr, this year's survey recorded 1,303 Nilgiri Tahrs in Tamil Nadu and 1,352 in Kerala, marking one of the highest combined population estimates in decades. "This is not just a count. It's a confirmation that targeted conservation, rooted in science and supported by political will, works," said Supriya Sahu, Additional Chief Secretary, Environment, Climate Change and Forests. The large-scale survey spanned 14 forest divisions, 43 forest ranges and 177 survey blocks, including 36 newly-added habitats. It involved 786 trained personnel, integrating modern tools such as drone reconnaissance, GIS mapping and the Double Observer and Bounded Count methodologies to ensure accurate and repeatable results. Key Highlights Sex ratio stands at 49 males per 100 females, while the young-to-female ratio is 50 to 100 - indicating healthy reproduction. New sightings were recorded in low elevation zones like Peyanar (270m), the lowest ever recorded habitat for the species. Mukurthi and Grass Hills National Parks remain core habitats, while fragmented and recolonised landscapes in Kodaikanal, Theni, Tirunelveli and Kanyakumari offered fresh hope for species expansion. Crucially, this year's survey included a new threat assessment module, documenting the challenges Nilgiri Tahrs face - habitat fragmentation, invasive species, forest fires and human encroachment. Launched by Tamil Nadu Chief Minister MK Stalin in October 2023, Project Nilgiri Tahr has rapidly evolved into one of India's most ambitious single-species recovery programs. It includes shola grassland restoration, radio-collaring for tracking, disease diagnostics and plans for captive breeding and reintroduction into lost habitats. With the declaration of October 7 as Nilgiri Tahr Day to honour conservation pioneer ERC Davidar, the state continues to blend science, tradition and stewardship to protect this iconic mountain ungulate. "Protecting the Nilgiri Tahr is protecting the soul of the Western Ghats," said Project Director MG Ganesan, adding that the findings will now guide future adaptive conservation strategies.

Survey finds 1,365 Nilgiri tahrs in Kerala
The joint Nilgiri tahr census in Kerala and Tamil Nadu reported a population of 2,668 Nilgiri tahrs. According to Forest department officials, 1,365 tahr belong to Kerala and 1,303 to Tamil Nadu. The Eravikulam National Park (ENP) is home to the largest contiguous population of Nilgiri tahr in Kerala, numbering 841 individuals. Officials said that in 2024, the number of tahrs in the ENP was 827. Ninety percent of the tahr population in the State is found in the Munnar landscape alone. A major presence of tahrs in Tamil Nadu is reported in Mukurthi National Park and Grass Hills National Park, lying across the Kerala State border. The growing tahr population points out the need for interstate cooperation and coordinated management of Nilgiri tahr protected areas. Grassland availability The controlled burning practice in Eravikulam National Park (ENP) was behind the success of the increasing number of tahrs. According to officials, of the total 1,365 Nilgiri tahrs in the State 1,126 were found in the Munnar landscape. Of this, the ENP is home to 841 tahrs. Munnar Wildlife Warden K.V. Harikrishnan said the nutritious grasslands of the region are behind the success of the tahr population in the park. 'In the nexy three years, controlled burning will be conducted in 97 sq km area of the park. 'The grasslands of ENP become unsuitable for grazing every three years after completing the growth of the natural grass. Nilgiri tahr and other animals will not feed on such grass. Then, controlled burning was introduced in the grasslands of the park on a rotational basis. The practice is conducted after removing all animals from the grasslands,' said Mr. Harikrishnan. 'This year alone, 144 new tahr births were reported in the park. Newborn Nilgiri tahr calves are eating the newly grown grass from the grasslands. Besides ensuring food security for the Nilgiri tahrs, controlled burning also helps increase the productivity of these animals. Nilgiri tahrs are a major prey for tigers and leopards inside the ENP, which in turn helps maintain the population at a controlled level,' said the warden. The warden stated that the easy availability of prey inside the park has helped lessen the straying of tigers and leopards outside of the park and into human habitat. The Forest department first took up the controlled burning practice in Eravikulam around 30 years ago, based on the know-how of the Muthuvan tribal communities, said officials. Standardised survey techniques The joint population estimation of Nilgiri tahrs was conducted continuously for four days in 89 census blocks in Kerala and 182 census blocks in Tamil Nadu. In Kerala, the census was conducted in 19 forest divisions, from Thiruvananthapuram to Wayanad, and all reported the presence of Nilgiri tahr. 'The use of standardised techniques such as the 'Bounded Count and 'Double Observer' methods contributed to improved data reliability of the tahr survey,' said an official. According to officials, historically, Nilgiri tahr occupied a wider range across the Western Ghats, much of which has been lost to plantations, infrastructure development, and land-use change. The Population Estimation 2025 aimed to explore historically known areas and gather information on fragmented tahr populations, as well as the potential for re-establishing habitat connectivity to restore these populations. The survey also discovered the biodiversity richness of tahr habitats, which host apex predators such as the tiger, leopard, and dhole, as well as endemics like the Nilgiri langur and lion-tailed macaque. Minister for Forests and Wildlife Protection A.K. Saseendran released the census report on Tuesday at Thiruvananthapuram during the 50th anniversary of the establishment of ENP in Munnar.
