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 number of bears accounted for – the lowest count among all – about 10, while the discrepancy between whale and dolphin population sizes was roughly 70, 80 and above 145 respectively. From the beginning till 2019, the number of bears faced a gradual increase of approximately 100, while the dolphin count followed a reverse trend and decreased by about 120. Witnessing a moderate decline of less than 15 by 2018, whales were recorded almost the same as bears until 2019.
Over the rest of the period, the biggest mammals experienced a slight fluctuation in numbers with an overall drop of below 30. The category representing bears 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 number of dolphins over the last 3 years, and it was equal to 0 by 2022.
