Tiger Conservation Hinges on Ecology, Not Politics, Says Expert

International Tiger Day serves as a reminder that wildlife conservation operates on ecological principles, not political schedules, according to conservationist R Reza Khan. Governments often set targets within electoral or administrative terms, leading to pressure for rapid population increases that are unrealistic for species like the Bengal tiger.

The Bengal tiger is a slow-breeding species. Females mature at three to four years old and typically have one litter every two to three years. High cub mortality due to disease, territorial disputes, food scarcity, or natural disasters means populations grow gradually, even under ideal conditions. Furthermore, an ecosystem's carrying capacity, limited by prey availability, freshwater, habitat quality, and human interference, dictates the maximum population it can sustain.

Wildlife does not follow political timetables.

This ecological reality is particularly pertinent for Bangladesh, where the entire breeding population of Bengal tigers resides solely within the Sundarbans mangrove forest. Unlike countries with multiple tiger habitats, Bangladesh lacks a secondary refuge should disease, climate change, or a major cyclone devastate the Sundarbans. The national animal's future thus hinges precariously on the health of this single ecosystem.

Even under ideal conditions, tiger populations grow gradually rather than dramatically.

The Sundarbans, while globally significant, presents a challenging environment. Increased salinity, reduced freshwater flow, frequent cyclones, tidal flooding, and relatively low prey density all constrain the number of tigers the forest can support. Human activities, such as fishing, crab hunting, and honey collection, further complicate conservation efforts.

Against this backdrop, Bangladesh's tiger population has stabilized at an estimated 110 to 125 individuals in recent years. This stability, Khan argues, should be viewed as an encouraging conservation success within a fragile ecosystem. Globally, wild tiger numbers have increased from a low of approximately 3,200 in 2010 to around 5,500 today, thanks to enhanced protection and conservation initiatives. However, this figure remains a fraction of historical populations, underscoring the ongoing need for dedicated conservation efforts.

Stability in such a fragile ecosystem is an important conservation achievement.
