The line graph illustrates the trends in wildlife counts of bears, dolphins, and whales over a five-year period from 2017 to 2022.
Overall, bear numbers increased dramatically, and the quantity of dolphins decreased steadily throughout the period, while whales experienced pronounced fluctuations in their figures. Notably, bears, which started with the smallest group size, overtook both species, becoming the most numerous of the three by the end. In contrast, having started as the dominant mammals, dolphins experienced sizable reductions in their total numbers, thereby becoming the least abundant by the end.
The figure for dolphins declined steadily throughout the period. The dolphin stock stood at 150 individuals in 2017 before decreasing substantially to just over 80 the following year. Although their numbers continued to shrink rapidly until 2019, when the count reached approximately 27, it kept decreasing afterwards, albeit at a less steep rate, leaving a single individual by 2022.
Conversely, the bear population followed an opposite trajectory. Starting the period with approximately 7 individuals, bears saw a significant increase in numbers, reaching parity with whales at just over 60 in 2018. In the following few years, the bear count first surpassed dolphins and then whales before continuing to rise markedly, reaching a peak of about 182 individuals at the end of the timeframe.
Meanwhile, the whale figures fluctuated across the period. Initially, the number of whales was 80, which then dropped slightly in 2018, before reaching a peak of 100 in 2019. It fluctuated moderately over the following years before finishing second with nearly 73 individuals.
