Experts express concerns for animal safety as heat waves continue to rip through the Pacific NW
Record heat waves have scorched the Pacific Northwest in recent weeks, prompting raging fires and devastating droughts across the region. The extreme weather has been blamed for the deaths of hundreds of people. But the toll among the region’s animals has been far greater, with the shifting climate threatening to permanently alter the area’s biodiversity.
Conservationists and scientists say the changes have been coming for years: Rising temperatures have coincided with drier conditions in parts of the Pacific Northwest, shaping the ways habitats interact with organisms. The full scope of the ramifications is still being studied, but it is expected to be extensive.
“It’s a big unknown,” said Jay Kehne, a conservationist and member of Conservation Northwest, an organization that aims to protect and conserve the region’s wildland and wildlife. “It’s really hard to grasp all the changes that can come from those really incremental changes.”
How does extreme heat affect animals?
Extreme heat, coupled with drier conditions, can significantly alter animals’ habitats. Dry winters can weaken plants and their leaves, diminishing potential food sources for wildlife. Mussels, barnacles and seaweed populations have faltered, impacting shoreside food chains. The shrubsteppe, a parched ecosystem located in eastern Washington, is an essential habitat for much of the state’s fauna, including sagebrush. However, under the strain of development and climate change, an estimated 80 percent of the shrubsteppe has been lost, according to the Washington Department of Fish and Wildlife.
