The annual synchronised survey of the Nilgiri Tahr serves multiple purposes aimed at ensuring the species' survival. Primarily, the survey estimates the population, tracks demographic trends, assesses reproductive health through monitoring mother-offspring interactions, and identifies various threats to their habitat.
The inaugural survey conducted in 2023 revealed a population of 1,031 Nilgiri Tahrs in Tamil Nadu. When factoring in Kerala’s Eravikulam National Park, the total population reached 1,858. The survey indicated healthy demographic ratios; however, it also noted the extinction of the species in certain traditional habitats, raising concerns for conservationists.
Kerala has confirmed its participation in this year's survey. The state's forest department plans to survey 9–10 blocks adjacent to Tamil Nadu, aiming to provide a comprehensive assessment of the Nilgiri Tahr population across state borders.
The Nilgiri Tahr is classified as endangered due to several challenges, including habitat degradation, fragmentation of grasslands, the invasion of non-native species, and potential threats from poaching or disease. These factors have contributed to significant population declines over the years.
Launched in October 2023, Project Nilgiri Tahr is a state-led initiative dedicated to the conservation of the Nilgiri Tahr and its habitat. The initiative encompasses synchronised surveys, restoration of grasslands, protection of ecological corridors, and management of invasive plant species.
The recent observation of five Nilgiri Tahrs in the Megamalai Forest Division suggests the presence of potential new habitats. This discovery underscores the adaptability of the species and highlights the necessity for habitat connectivity and the protection of lesser-known ecological corridors.
Local extinctions in regions like Budha Gundu and Glenmorgan raise significant concerns. They indicate ongoing ecological stress and the loss of viable habitats, suggesting that these areas can no longer sustain Nilgiri Tahr populations. This reality calls for targeted restoration and protection efforts to ensure the species' survival.
The survey has revealed a 1:2 male-to-female ratio and a 2:1 female-to-young ratio among the Nilgiri Tahr. These ratios illustrate a strong reproductive potential, indicating that if external pressures are mitigated, the species could have a promising chance for long-term recovery.
Q1. What is the main goal of the Nilgiri Tahr survey?
Answer: The survey's main goal is to estimate the population, track trends, assess reproductive health, and identify threats to the Nilgiri Tahr's survival.
Q2. What did the 2023 survey reveal about the Nilgiri Tahr population?
Answer: The 2023 survey reported 1,031 Nilgiri Tahrs in Tamil Nadu, totaling 1,858 when including Eravikulam National Park in Kerala.
Q3. Why is the Nilgiri Tahr endangered?
Answer: The Nilgiri Tahr faces endangerment due to habitat degradation, grassland fragmentation, invasive species, and possible poaching or disease.
Q4. What is included in Project Nilgiri Tahr?
Answer: Project Nilgiri Tahr focuses on conservation through synchronised surveys, grassland restoration, corridor protection, and invasive species management.
Q5. Why are local extinctions significant for the Nilgiri Tahr?
