One of the very first canoe trips we took back in the 90’s was along Tomales creek outside Pt Reyes National Park. It was so early in the story and we were so ignorant of everything that we were not surprised to learn from one of the old timers we met along the way that a beaver dam that would have blocked our progress was just ripped out the day before by a neighbor.
This stands out in my mind because we haven’t since run into beavers in the area and Marin has been hungrily exploring beaver benefits. There was a talk last night in Olema by our friends Brock Dolman and Kate Lundquist. Jerry Meral was governor Brown’s water tzar and he’s eager for beavers to come back to Marin.
The following video is a recording of the informational webinar Brock Dolman and Kate Lundquist (Occidental Arts & Ecology Center WATER Institute Directors) gave on March 4, 2021 to those living and/or working in the Olema Creek watershed near Point Reyes National Seashore in California.
Co-hosted by the Environmental Action Committee and the Olema Association, webinar topics include the fascinating history, ecology and benefits of beaver in California and the initial results from the West Marin Beaver Restoration Feasibility Assessment Brock and Kate have been carrying out with the help of their Marin County based steering committee. The 45-minute presentation is followed by a question and answer session.
Please note, the recording begins a couple of minutes after the start of the webinar. Apologies to our co-host and esteemed Steering Committee member Jerry Meral for not capturing his warm welcome and introduction.
I don’t dust off the Star Wars regalia for just any good beaver article. It’s reserved for very special ‘it’s-about-fricking-time’ occasions. But oh-boy this is one of them. Let’s all assume it’s the best possible omen for 2017 and set our phasers to ‘savor’. The author is Gerald Meral, who was the top water advisor for the governor of California until he retired at the end of 2013. Which means he knows everyone and everyone knows him. He’s currently working with the Natural Heritage Institute. I’m just printing the entire article because you need to read it all. Trust me.
Here’s a pop quiz about beavers. Which Northern California counties don’t have any beavers? Answer: San Francisco (no surprise), Santa Cruz and Marin. Every other Northern California county has a thriving beaver population.
Beavers are a cornerstone environmental species. These hardworking aquatic engineers build dams in streams, and those dams perform environmental miracles. By storing water they recharge groundwater, preparing the region for droughts. The ponds are vital rearing habitat for coho salmon, steelhead and other fish species. The adult fish easily pass over the beaver dams on their way upstream from the ocean. Beaver ponds promote the growth of riparian (streamside) vegetation, creating habitat for native birds and other wildlife.
Beavers were present in Marin County prior to European arrival, but were wiped out by hunters and trappers. In the 1940s the California Department of Fish and Game (now the Department of Fish and Wildlife) relocated some beavers to Glenbrook Creek on the Point Reyes Peninsula in a progressive attempt at ecosystem restoration, but the transplant did not take.
Beavers can cause problems. Their dams can flood infrastructure like roads. They can also build dams at inappropriate places along creeks, blocking important water diversions. And of course they cut down small trees along the streams, sometimes to the dismay of nearby property owners.
But there are many modern techniques available to manage beaver populations.
Using recordings of the sound of running water, beavers can be induced to build their dams where they will do no harm, and create beneficial habitat. Careful placement of structures in streams can guide beavers to build where it will do the most good.
As the beavers multiply and colonize new areas, they can be carefully managed. If they get into stream segments where they might cause problems, they can be trapped and relocated.
Farmers sometimes are concerned about beavers impacting streams on their farms. Fortunately in Marin County, beaver dams are likely to improve local surface and groundwater supplies on our relatively small streams, improving water supply for agriculture. Beavers are not an endangered species, so their introduction will not add any new regulations, often a concern for farmers.
So why haven’t beavers been re-introduced to Marin County by now? State Sen. Peter Behr was rebuffed by the Department of Fish and Game in the 1970s when he sought to bring back beavers.
At that time, the department was mainly concerned about problems beavers might cause landowners. Today, the department recognizes the many benefits beavers bring, but still fears criticism and possible liability if they move beavers.
The answer is to allow the Marin County Board of Supervisors to have the authority to relocate beavers to our county. Landowners in the relocation area would be carefully consulted, and a plan of relocation and management would have to be adopted. The goal should be to benefit coho salmon and steelhead, species which are greatly threatened in our county.
Reintroduction would be coordinated with the Resource Conservation District, Marin Municipal Water District and other interested agencies and nonprofits. Legislation to allow Marin County the right to bring back the beavers should be introduced and passed as quickly as possible. The beavers want to come home to Marin.
Jerry Meral of Inverness is the director of the California Water Program for the Natural Heritage Institute.
Whoohooohoo! If there is EVER going to be legislation that allows beaver reintroduction it’s going to be from Marin. They have enough lawyers and enough land and enough money: they will get this done, mark my words. Jerry got his info about beaver population from Eli Asarian’s beaver map, which isn’t exactly time sensitive – but it’s a good general indication. Here is our county map of places that didn’t need depredation permits last year, which I think is a better clue about where beavers aren’t right now.
I really appreciate his look at history for this article. I didn’t know about Peter Behr and will find more. I’m not wild about his saying that beavers can be controlled by the sound of running water and when I mentioned this he explained it was from Jari’s documentary (Michel LeClair). In general we find better success with flow devices and beaver dam analogs (BDAs) because beavers like to build where it’s easy. But we’re pretty happy with this article. It’s an awesome way to start the year.
Speaking of awesome ways to start the year, a dozen beaver champions are coming tonight to welcome 2017 with four courses of homemade ravioli’s and beaver shortbread cookies. Everything is ready but the boiling water. We’ll make sure to toast Marin especially. Happy New Year!
