A new study found that while belugas in healthy populations give birth every two to three years, Cook Inlet belugas have been reproducing every four years.
Trained beluga monitor Kelly Hild, of Kasilof, watches for belugas on the bluff in Kenai in March 2022.
“Getting that demographic piece in place and understanding that helps us to get closer to identifying what might be the external factors that are limiting their recovery,” she said. Rebecca Taylor, from the Alaska Science Center, was another author on the study. She said researchers also used the photo data to measure survival rates in the population, which they also found were lower than expected.
