Pikas rebound in Columbia Gorge after 2017 Eagle Creek Fire

American pika

Recent surveys show that the American pika — the potato-sized rabbit relative known for sounding like a squeaky toy — is making a strong comeback in the Columbia Gorge after the 2017 Eagle Creek Fire.

The Oregon Zoo says pikas typically live on mountain slopes at elevations above 6,000 feet, but a somewhat anomalous low-elevation population is living in the Gorge, just a half hour from Portland. 

Here is more from the Oregon Zoo:

Each summer, volunteers from Cascades Pika Watch — a collaboration of organizations and researchers convened by the Oregon Zoo — head into the field with binoculars and GPS units to stake out pika hot spots, record their locations, and listen for the telltale squeak. Then they upload their data to a website where it’s analyzed by biologists to better understand where pikas live and whether their range is shifting. 

Over the past five years, biologists have been especially eager to track how pikas are faring in those areas most affected by the Eagle Creek fire. This year, volunteers reported pikas at 23 out of 31 sites surveyed, an increase of more than 50% since 2018.

“The population in those areas hasn’t quite reached its pre-fire distribution, but it’s getting close,” said Dr. Johanna Varner, scientific adviser for Pika Watch program. “This is very encouraging news for everyone monitoring the Gorge pika population.”  

In addition to the reported increase in pikas reported this year, Cascades Pika Watch benefitted from a record number of volunteers: 168 trained citizen scientists spent 1,620 hours searching for the tiny mammals. No easy feat, considering how difficult pikas can be to spot.  

“Because they are small and blend in so well with their rocky habitat, they can be hard to find,” Varner said. “Especially if you don’t know what to look — or listen — for. We’re extremely grateful to have so many dedicated volunteers who are trained to find them.” 

Cascades Pika Watch will return next year, and aspiring pika watchers are encouraged to sign up for a free in-person or online training. Sites are accessed via public hiking trails, and no special skills are required. The training schedule will be announced in spring 2024.
