The bar chart shows the total number of tigers in all tiger reserves in India between 1972 and 2002. The line graph shows how the number of tigers changed in five different tiger reserves during the same period.
Overall, the total tiger population in India increased a lot over the years. Among the five reserves, Bandipur always had the highest number of tigers, while Buxa had the lowest.
In 1972, there were only 268 tigers in all reserves. The number rose quickly to 711 in 1979 and kept growing to 1576 in 2002. There were some small changes in the 1990s, but the general trend was upward.
In Bandipur, the number of tigers increased sharply until 1984, reaching more than 250, and stayed high until 2002. Corbett and Kanha also showed slow but steady growth, ending at about 140 and 120 tigers. The Sunderbans had a smaller increase, from around 50 to 80 tigers, while Buxa always had fewer than 20 tigers.
In conclusion, the total number of tigers in India rose a lot between 1972 and 2002, and Bandipur remained the most successful reserve for tiger conservation.
