The chart illustrates the wildlife population in terms of 3 species, namely bears, dolphins, and whales between 2017 and 2022.
Overall, the count of dolphins and whales decreased over the period, while that of bears witnessed a reverse trend. Additionally, the number of bears showed the most significant growth.
Looking at the line chart, dolphins began the period at approximately 150, before plunging to precisely under 40 in the following two years. Subsequently, it declined at a relatively lower number to precisely zero species.
On the other hand, bears accounted for only about 10 in 2017; however, they recorded a remarkable surge over the years and reached over 180 by 2022. Lastly, whales experienced a significant decline to below 60 after a year, then continued to rise rapidly to 100 in 2019. By contrast, since 2019, bears saw a fluctuation between 60 and 90 species during the rest of the period.
