The line graph illustrates the wildlife population in terms of 3 species, namely bears, dolphins, and whales during a 5-year period from 2017 to 2022.
Overall, although initially dominating all three categories, the dolphin population decreased the most by the end, while the bear population exhibited the opposite trend, ultimately outnumbering the other species notwithstanding its initial smallest count.
In the beginning, the bear count was the lowest among all, at around 10. The disparity between the whale and dolphin population sizes was approximately 70, 80, and over 145, respectively. From the beginning until 2019, the bear population experienced a gradual increase of about 100, while the dolphin count followed an opposite trend, decreasing by around 120. Witnessing a moderate decline of less than 15 by 2018, the whales were recorded almost the same as the bears until 2019.
Over the rest of the period, the largest mammals experienced a slight fluctuation in numbers, with an overall drop of below 30. The bear category thereafter followed the same trend and reached a high of 140 in 2021, just before it grew considerably and reached a peak of approximately 180. Lastly, there was a slow plunge in the dolphin population over the last 3 years, and it reached 0 by 2022.
