“Wolves, Rewilding, & Changing Climate”
Bill RIpple, April 16 at 7:15 pm
Bill Ripple’s wolf research focuses on restoration, and his broader work emphasizes the need to protect and restore biodiverse ecosystems to help manage the climate emergency. Ripple argues that preserving intact ecosystems with natural predator-prey dynamics is vital for ecosystem resilience in the face of rapid climate change.
“The restoration of wolves and other large predators has transformed parts of Yellowstone, benefiting not only willows but other woody species such as aspen, alder, and berry-producing shrubs.”
Members and non-members are welcome to attend the meeting in person at the C3 Chandler Ballroom on NW Tyler Ave. in Corvallis. The social gathering starts at 6:30, business meeting at 7:00 pm, and the presentation starts as early as 7:15 pm and lasts about an hour. The Zoom link will be sent a few days before the presention. If possible, the link to the Zoom recording should be available the folloowing day.

Nature Neighbors: Bringing small natural areas together for wildlife
You can be a part of habitat conservation thanks to the new program called Nature Neighbors. Created by Benton Soil and Water Conservation District and Greenbelt Land Trust, the program goal is to protect and connect small habitat spaces throughout Benton County.
Lots of help will be available – one-on-one coaching, resources, and much more. Five actions that will help improve and protect your habitat are: plant natives, remove invasives, protect soil, conserve water, and attract wildlife.
Nature Neighbors will be introduced to the public on April 15 from 2:00 – 3:30 pm in the Corvallis Business Park. RSVP, Directions

Trip Details
Birding & Resources
Our region is a prime place to find, watch, draw, and photograph many species of birds. Half-day field trips to local areas and multi-day trips to regional birding areas are led by ASC guides. New birders and anyone else interested are invited to participate.
Learn how to use binoculars (bins), spotting scopes, field guides, and cameras. You will find that birders are the friendliest of all interest groups!
We also have links to eBird, Merlin, Xeno-canto, nest cameras, as well as other species, such as butterflies, dragonflies, native plants, and more.

Conservation
ASC participates in grassroots conservation by providing information about pending actions on national and state environmental laws. Locally, ASC partners with other organzations to conserve habitats, provide access on trails, and restore native plants.
Conservation of Western Bluebirds and Streaked Horned Larks are also major ASC initiatives.

Education
Check the website for the 2026 activities, locations, and dates. The Nature Center is open for special events and usually there is an Open House on Earth Day.
Education volunteers offer activities such as making bird masks, leading guided walks, crafts, and even measure your wingspan to see how you compare to local birds.
Visit the museum room to see taxidermied birds common to our area. Explore the feather and bone case, play nature games, and learn about birds — how feathers work, why beak length and shape matter, and measure your wingspan!

Bluebird Trail
The ASC Bluebird Trail promotes conservation of the Western Bluebird (Sialia mexicana) and other native cavity-nesters through field work, scientific studies, and education. Bluebird boxes have been placed in ideal habitats and are monitored throughout the breeding season. Results are reported to several organizations.
Learn about the Bluebird Lady and her successful efforts to save the declining population of nesting bluebirds in Benton and Linn counties.
