* Data Scarcity: Accurate population counts were very difficult to obtain in the past. The vast and often remote habitats of Bengal tigers made tracking them challenging.
* Varying Estimates: Different sources may provide different estimates, and these estimates are often based on limited data and educated guesses.
* Population Fluctuations: Tiger populations naturally fluctuate due to factors like prey availability, habitat loss, and poaching.
What We Do Know:
* Historically Low Numbers: By the mid-20th century, Bengal tiger numbers were already critically low due to hunting and habitat loss.
* Conservation Efforts: The 1970s saw the beginning of focused conservation efforts for tigers, including the establishment of protected areas.
Looking for a More Accurate Figure:
If you're looking for a more specific estimate, you could:
* Search for academic papers: Researchers have published studies on tiger population trends. Try searching in academic databases using keywords like "Bengal tiger," "population," and "1970s."
* Consult conservation organizations: Organizations like WWF or the Wildlife Conservation Society may have historical data or estimates.
Remember, any figure you find will likely be an estimate, and it's important to understand the context and limitations of that data.
