The line graph and table detail the population trends of three different animal species – bears, dolphins, and whales – over a six-year period from 2017 to 2022.
Overall, the data highlights a striking contrast between the trajectory of bears and dolphins. While the bear population underwent a dramatic and sustained increase to become the most dominant group by the end of the period, the dolphin population collapsed to near extinction. Meanwhile, the whale population exhibited moderate fluctuations, maintaining relative stability overall.
In 2017, dolphins represented the largest group with 150 individuals, followed by whales at 80 and bears at a mere 8. However, the number of bears experienced a rapid upward trend, reaching 93 by 2019 and surpassing both other species. This growth continued unabated, with the population culminating at a peak of 184 in 2022.
Conversely, the dolphin population plummeted continuously. From its initial high, the figure dropped sharply to 77 in 2018 and further diminished to 32 in 2019. By 2022, the count had fallen to an absolute minimum of just a single dolphin. The trajectory for whales was more erratic; after a temporary decline to 54 in 2018, it surged to 100 in 2019 before undergoing minor oscillations and settling at 72 at the close of the period.
