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 population was the smallest, around 10 individuals, while the whale and dolphin populations differed significantly, at around 70-80 and over 145 respectively. From the start until 2019, the bear count gradually increased by around 100, while the dolphin population experienced a reverse trend, decreasing by about 120. Whales witnessed a moderate decline of less than 15 by 2018, ending up with a count similar to the bears by 2019.
Over the rest of the period, the largest mammals (whales) saw a slight overall drop of under 30. The bear population continued this upward trend, reaching a high of 140 in 2021 before growing considerably to peak at around 180. Finally, the dolphin population saw a slow but steady decline over the last 3 years, reaching zero by 2022.
