About Petaluma Wetlands Alliance

What is PWA?
Petaluma Wetlands Alliance (PWA) was formed by a concerned group of citizens who banded together in the late 1990ās during the planning and construction of a new wastewater treatment plant in Petaluma, California. We work with schools, government agencies and environmental organizations to help preserve wetlands habitat.

What are Wetlands?
Wetlands are among the worldās most productive ecosystems, providing critical habitat for many plant and animal species. In essence, wetlands are the zones between the land and large bodies of water such as rivers, lakes, or oceans, where water tends to stand for prolonged periods of time. Swamps, marshes and bogs are all examples of wetlands.

How Can I Help?
Weāre glad you asked! There are a number of ways you can support the PWA. Financial contributions are always welcome. Since we are a 501(c)(3) organization, your donation may be tax-deductible. If you like to meet and talk with people, check out our our docent program. Or, pick up a shovel and come help us remove invasive weeds as a volunteer.
