Wild tigers are on the verge of extinction.
Poaching, habitat loss and fragmentation have reduced the global population of the tiger to less than 3,500 and the pressures continue to mount. Under the current scenario, it is predicted that the tiger may well be extinct within the coming decade.
The loss of the tiger will have implications much larger than simply the loss of a charismatic animal species. Habitats where wild tigers live are high-value ecosystems that provide vital services to humans, such as carbon sequestration, recreational services, maintenance of hydrological balance, crop pollination, protection from natural disasters and soil erosion and preservation of genetic diversity of plants. As an instance, tourism values from tiger habitats, though still under-priced, run into billions of dollars today and contribute to the livelihoods of millions of people worldwide.
Being at the top of the food-chain, the decline of large predators inevitably leads to over-abundance of herbivores such as deer, which in turn has repercussions on tree regeneration. Such imbalances reverberate through the food-web, causing species losses from fragile habitats. It has been amply demonstrated that lasting benefits from nature depend upon the maintenance of essential ecological processes and upon the diversity of life forms. By allowing tigers to go extinct, we would essentially be depriving future generations of the benefits from biodiversity that has been the bedrock of human progress. Above all, the loss of the tiger would take away the national impetus for saving natural diverse landscapes with intact ecological and evolutionary processes. Today, as an effective umbrella species, the tiger has become a powerful symbol of our ability to conserve wild nature.
The task of saving tigers and their natural habitats is a challenging one. Poaching of tigers continues unabated due to the weak institutional capacity for wildlife law enforcement in most tiger-range countries and the burgeoning global demand for tiger parts. Lack of scientific capacity for wildlife monitoring and management leads to further habitat deterioration in the face of changing and varied threats. Tiger landscapes continue to be fragmented and reduced by the day due to rapid infrastructural and industrial expansion and land use change from forests to plantations. In many cases, such habitat loss takes place far away from the public eye due to poor information flows and lack of communication. Over-exploitation of forest resources by dependent communities, who live well below the poverty line, contributes to the degradation of tiger habitat. Above all, policy-makers remain unaware of the immense economic value of living tigers and their natural habitats (both realized and potential) leading to low prioritization of conservation objectives in national planning.
