Volunteer-led field project combines hiking, science and cuteness
The Oregon Zoo is training volunteers ages 10 and up to seek out a species that's been called one of the "cutest endangered animals in the world."
Cascades Pika Watch — a collaboration of organizations and individual pika researchers convened by the zoo — is now in its fifth year, and citizen scientists from around the region are invited to help. On Wednesday, May 15 and Sunday, May 19, the zoo is offering free crash courses on how to identify pikas and take part in the project. Register and learn more here.
American pikas — tiny mammals known for their distinctive, squeak-toy-like calls —typically live on mountain slopes at elevations above 6,000 feet. Though not currently protected under the Endangered Species Act, pikas' particular habitat and temperature requirements make the species vulnerable to global warming trends — and of special interest to biologists studying the effects of climate change.
A somewhat anomalous low-elevation population of pikas is living at the Columbia Gorge — just a half hour from Portland. That accessibility, combined with the stunning scenery of the Gorge, has made for a popular citizen science program.
Each summer, volunteers 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. There's also a Cascades Pika Watch Facebook group, where volunteers share pictures and stories with each other.
"It's hiking with a purpose," said Pika Watch coordinator Amanda Greenvoss. "The sites we monitor are along public trails and are easily accessible. You get to enjoy incredible scenery while helping to maintain the integrity of that ecosystem."
The extra help biologists receive from volunteers is critical to making timely population assessments. Other pika populations have recently disappeared where they were observed less than a decade ago.
In 2018, many of the sites were closed due to damage from the Eagle Creek fire. Program staff hope to access more of the gorge this summer to give scientists a better understanding of post-fire pika abundance and recovery.
"Pika Watch is an ideal opportunity for people who love hiking and the outdoors to take action for wildlife," said Dr. David Shepherdson, the zoo's deputy conservation manager. "Conservation is ultimately only as effective as people's willingness to support it. And who could say no to a pika?"
Elsewhere in the Cascades, volunteers continue to collect opportunistic pika observations through the citsci.org database and app. There is also a very active cascades pika watch Facebook group where volunteers share pika pictures and stories from their surveys.

The Oregon Zoo is a service of Metro and is dedicated to its mission of inspiring the community to create a better future for wildlife. Committed to conservation, the zoo is currently working to save endangered California condors, Columbia Basin pygmy rabbits, Oregon silverspot and Taylor’s checkerspot butterflies, Western pond turtles and Oregon spotted frogs. Other projects include studies on black rhinos, Asian elephants, polar bears and bats.
The zoo relies in part on community support through donations to the Oregon Zoo Foundation to undertake these and many other animal welfare, education and sustainability programs. The zoo is located five minutes from downtown Portland, just off Highway 26 at exit 72. The zoo is also accessible by MAX light rail line. Visitors who travel to the zoo via MAX receive $1.50 off zoo admission. Find fare and route information online or by calling TriMet Customer Service at 503-238-RIDE (7433).
