The bar graph illustrates information about the tiger population at tiger reserves in India between 1972 and 2002 while the number of tigers at five different preservations are described in the second chart, a line graph.
Overall, it is evident that the tiger population started to see significant upward trends over a 2-decade period while the reverse is true for the initial years. Interestingly, all tiger reserves with the exception of Bandipur showed nearly the same statistics.
Upon a detailed look, in Indian preserves only conserved 268 tigers initially. While in 1979 the number of tiger habitats revealed 711, that of continued to improve, showing just 1121 in 1984. There was a marginal difference (39%) for the population of tiger between 1989 and 1993, and this index dropped by 33%, however. Also, from 1997 to 2002, the tiger population remarkably increased, 1498 tigers were retained on the former year, 1576 of them did so on the latter.
As regards the chart illustrating the number of tigers, it is clear that there were five diverse conservation areas for tigers: Bandipur, Corbett, Kanha, Sundarbans and Buxa. Although the percentage of tigers in Bandipur stood at well over 50% in 1972, it reached a peak just 250% afterwards, highlighting the highest figures ever recorded. Additionally, the index of tigers in the Corbett and Kanha commenced at 50%; however, the figures had experienced fluctuation until 1989, and finished at just under 150%. Ultimately, the proportion of tigers in Sundarbans and Buxa accounted for a negligible figure in the previous year, they saw a minimal growth, the former was around 60%, the latter registered roughly 10%.
