Because the beaver isn't just an animal; it's an ecosystem!

Tag: Ann Riley


I had a nice surprise yesterday in the mail with the arrival of Ann Riley’s much awaited urban creek book. Her first one published 25 years ago and became the restoration bible. It is still a valuable asset and regarded as a necessary resource even though others on the subject have been published since.  This second one is all about successful creek restoration stories – both labor intensive and natural. And guess who’s in it from page 171-179? That would be the story of the Martinez Beavers, who moved into an urban creek and transformed it all by themselves.

rileyRiley has been a good friend of the beavers over the years but she wasn’t exactly forthcoming with this part of her book. It was strange and exciting to read our story told by an outsider and see myself consistently described as ‘Perryman’. Ha. The scan came out horrible but here are some wonderful segments worth sharing.

CaptureI love having this documented correctly in a book that will likely survive the next 25 years and beyond. Riley works for the SF waterboard and has done several trainings about planting trees out here. It’s through her that we were able to have the watershed stewards the last couple of years working with  the conservation core. I particularly love how she cracks open the creek scientists pretend enviromental reports that the city paid for to  have justification for their impulses. And of course I loved THIS.

Capture1How happy do you think the city will to be to read about that historic sheetpile? Maybe they’ll throw me a parade? That whole ordeal was such a nauseating bundle of tension that I have long repressed it: I was terrified every moment that the beavers would be killed. I can’t believe they survived. And I remain very partial to this video.

Capture2I am bursting with pride at this paragraph and you can certainly see why this reference made the wikipedia challenger disappear. Maybe its just me but I find it a little terrifying that many years ago in a panic I just happened to come across the 2005 ecological survey and made the decision to contrast it with the species we saw over time. I’m sure there were all kinds of reasons a well-trained person wouldn’t have done it. But I was right here when it all happened, and I remember how rare a thing it used to be to see a green heron  or muskrat in the creek and how common it became.

More than anything else in the ENTIRE world I am wishing that some other city looks at this chapter and says hmmm, maybe we should try that. (And I’m looking at you, Mountain House). If allowing beavers to restore urban streams needed to be proven then I’m thrilled that Martinez was a testcase.  I met Riley through Lisa Owens Vianni who I met through the SF bay Estuary project where she used to work. That got my foot in the proverbial door but it was my presentation at the Santa Barbra Salmonid Restoration Conference that impressed her.

She said it was might have been the best presentation they ever had.

There are a few picky things I would have changed about this chapter. The meeting wasn’t in chambers it was at the High School, and it was a Sacramento Splittail not a SPITTAIL and good lord I never want 5000 people at the beaver festival! But I’m so happy we’re in this very important book and the role our beavers played is documented forever. Thank you Ann Riley for bringing our story to the next level.

Anyone who cares about creeks and beavers should go buy a copy right now. It will pay for itself may times over.

 


I invited a new team member onto  the urban beaver chapter because they told me I could. I felt we needed more water weight in our cluster, and first thought of good friend Ann Riley who is too busy with her third book to help. That of course meant I needed to ask Dr. Ellen Wohl who was surprisingly interested and willing to assist. In case you’ve forgotten who she is, shes a professor of geo sciences at Warner College in Colorado who has written a great deal on beaver, rivers, and climate change. This audio is a great introduction. It’s taken from a few moments of her interview on Santa Fe Radio, and happens to be the smartest most tightly packed summary of beaver benefits I’ve ever heard.

Ellen suggested we consider using a tool for analyzing the likely role of a beaver dam risk and contribution of woody debris. Her paper on the topic is coming out soon and she attached a copy for review, with sections about the value of woody debris to invertebrates and fish that immediately translate to beaver dams. I thought for sure it would interest Michael Pollock and sent it along to him. He got very excited and thought it was a great idea to inform our paper.

Which just goes to emphasize that they are all super smart in their relative fields. And I just make connections. Because its what I do.
