Helping bats in Washington State

Bats Northwest envisions a future where the essential role of bats is understood, the public recognizes the vital place of bats in our environment and economy, and where all are inspired by their remarkable and invaluable contribution to our natural heritage.

Upcoming events

  • Wenatchee River Institute Bat Night

    Tuesday, July 8 7:30 PM - 10:00 PM

    Bats Northwest is heading to Eastern WA, for a wonderful family friendly Bat Educational event with the Wenatchee River Institute, WA Dept. Fish and Wildlife and Happy Valley Bats. Come join us in Leavenworth for a bat talk to learn all about bats. Registeration is required for this event.

  • Green Lake Bat Talk

    Thursday, July 10 8:15 PM- 9:30 PM

    Join us for our first Bat Talk of the summer! This is a informational talk, so bring a chair and come learn about our local bat species and find out how you can help protect bats. The sun sets at 9:06pm so hopefully the Green Lake sky will have some bats flying above us. This program is free and open to everyone, no registration needed.

  • Green Lake Bat Talks

    Our summer programs at Green Lake in Seattle are kicking off. Come learn about our local bat species, and find out how you can help protect bats. These programs are free and open to everyone. Mark your calendars as our Bat talks will be July 10th, July 24th, Aug 14th and Aug 28th. We will also have two (2) Community Science for Bats Night on July 31 and Sept 4th which will require registration.

Get Involved

Bats are at risk as a result of habitat destruction, the introduction of invasive species, hunting, and climate change. Bat populations could continue to decline, and without intervention, these threats could lead to species extinctions.

We have the power to help bat populations throughout Washington by working together. Join us in our mission to increase public awareness and promote a greater appreciation for bats.

White-nose syndrome

White-nose syndrome (WNS) is a disease that affects hibernating bats and is caused by a fungus, Pseudogymnoascus destructans, or Pd for short. Pd grows in cold, dark and damp places. It attacks the bare skin of bats while they’re hibernating in a relatively inactive state. As it grows, Pd causes bats to become active more than usual and burn up fat they need to survive the winter.

Community Science

Bats Northwest conducts and supports several research efforts in Washington.

Our volunteers aid in long-term acoustic monitoring projects in the Puget Sound area to gain insights into our species and their range. Programs like Bat Activity Trends (B.A.T.) involve the public in collecting observational data on local bat activity, teaching us about the habitats that support bats.
