Free workshop for individuals and stewards of natural areas
in Walnut Creek's Civic Park

For more details and to sign up
Sponsored by the California Invasive Plant Council, City of Walnut Creek, and the Walnut Creek Watershed Council (of which Friends of the Creeks is a member)
Creek Restoration Workdays 

We are transforming a weedy area of creek bank in Civic Park into a meadow of wildflowers and native grasses.  This season's work started in January -- we're cleaning up weeds and planting new seedlings.

Join us for some rewarding work, camaraderie, and sometimes a brief talk about an aspect of creek ecology.  No experience is required -- just a desire to make the creek a better place for both humans and wildlife.

A Year of Arundo

As members of the Walnut Creek Watershed Council, we joined the watershed-wide focus on arundo this year.  Arundo (a relative of bamboo) is the single worst weed in California creeks, and we have a lot of it in certain areas of our watershed.  We are taking a three-pronged approach:

The first phase was to map the arundo.  A member of Friends of San Ramon Creeks with GIS expertise led this effort.  DVC provided assistance with drones.

Second, much of the land along creeks is in private ownership, making it essential to reach out to the owners to educate them about arundo removal if our project is to be a success.  We have held several meetings to do this, including a watershed-wide evening event at DVC attended by about 100 people.

Third, the arundo needs to be replaced by plants, preferably native ones, that are beneficial to wildlife and pollinators and will stabilize the creek banks.  Creeks are important wildlife highways. We will begin this work in the coming year.

Friends of the Creeks led four arundo removal events and
participated in filming a video which you can see here.

Thank you to all our creek cleanup volunteers
Our 140 volunteers took 16 cubic yards of vegetation and debris out of the 2.5 miles of creek channels in downtown Walnut Creek.

Photos from the 2018 creek cleanup are available here.

Join us for our 30th anniversary next year!

Workshop topics will include:
  • The biology and ecology of invasive plants
  • Invasive plant management tools and best practices
  • Online resources to assist you with your project, including Calflora and Cal-IPC
  • Using Calflora Observer Pro app to map and monitor invasive plants
  • Strategizing and prioritizing habitat stewardship projects
  • How local volunteers are tackling Arundo throughout the Walnut Creek Watershed
  • How you can get involved with this effort
