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

Month: June 2023


The good news about beaver and salmonids has pretty much reached everywhere except for parts of Minnesota and Wisconsin. Take a listen to this report from Minnesota. It discusses their no tolerance policy and some crazy new research.

New research? Try 20 years old research.

Leave It To Beavers?

“Kill them all,” Croke remembers them saying.

They were killing beavers to help fish, particularly steelhead trout. And they’re still doing it today. But some people are not on board with that. Today’s episode is all about that conflict, and about how our scientific understanding of the role of beavers may be changing.

And, of course, they say they’re bad for trout.

But new research shows it could be the exact opposite – that beavers might not be so bad for trout after all.

In 2018 and 2019, scientists at the University of Minnesota Duluth studied dams on a couple of rivers in the state, including the Knife. And, in those spots, they found that, during their study, dams didn’t necessarily block fish from migrating up and down the river.

Professor Karen Gran led the research team.

KAREN GRAN: So as long as water was able to get over the top of the dam at some point during that time period, the fish were able to move over the dam.

Please could someone explain to me why on God’s Green Earth beavers would be bad news for trout near the great lakes but good news for trout in every other place? And how trout used to survive before people were on hand to kill all the beavers? Or how hyporheic exchange means beaver ponds cool water for trout?

But never mind. These questions mean nothing in Minnesota. I guess we should be grateful they are starting to ask them at all.

Let’s comfort ourselves with more awesome photos from Rusty Cohn’s visit to the North pond in Napa last night. Them’s are the ridingest beavers I’ve ever beheld. Lucky for us. Not so lucky for that crayfish I guess.




I came across this written stepwise outline for beaver depredation in California and thought I’d share some thoughts. Keep in mind that in some regions most of these steps already happen: I’ve seen a small percentage of reports that describe in detail the reasonable efforts taken to try and resolve the problem without trapping.

Sometimes it’s just summed up in one terrible word. “Hazing”.

As a keystone species and ecosystem engineer, the North American beaver (Castor
canadensis) provides ecosystem services that promote biodiversity protection, habitat restoration, and wildfire-resilient landscapes in California, as aligned with the State Wildlife Action Plan (SWAP, 2015) and the state’s Natural and Working Lands Climate Smart Strategy (Executive Order N-82-20). Beavers also have an ecological relationship to many species listed under the California Endangered Species Act (CESA; Fish & Game Code (FGC), §2050 et seq.) and/or federal Endangered Species Act (ESA; 16 U.S.C. §§1531-1544). The Department of Fish and Wildlife (Department) is committed to ensuring that humans and beavers can coexist, recognition of their ecological value, and that the removal of any depredation beaver is done in a thoughtful manner.

You hear that? No more thoughtless manners when it comes to killing beavers. That should mean no more permits issued for UNLIMITED numbers of beavers, right?

The Policy outlined in this document is intended to implement a deliberative, tiered approach when responding to reported beaver depredation. The Department will promote the use of various nonlethal beaver damage deterrent techniques to resolve depredation  conflicts where feasible. This approach is consistent with FGC section 4181, California Code of Regulations (CCR) Title 14 section 401, the CDFW Ecosystem Services Policy (DB 2017-06), and the Fish and Game Commission Policy on Depredation Control. Therefore, we are providing the following direction for all beaver depredation permits issued in the state. Authorizing the removal of beaver dams is beyond the scope of this policy and may require federal, state, and/or local authorizations (e.g., FGC section 1602
agreement, FGC section 1610 emergency notification, CESA Incidental Take Permit).
Additionally, this Policy is intended to support coordination between the Human-Wildlife Conflict (HWC) Program, HWC staff, wildlife unit biologist, and others (responders), and the newly established Beaver Restoration Program (BRP). Upon completion of the Department’s new Beaver Management and Restoration Plan, the BRP will conduct beaver conservation translocations to restoration and reintroduction sites approved by the Department. When and where opportunities exist, the BRP will seek to utilize depredation beavers in its projects. Such efforts will require advance communication among the BRP and appropriate Department staff about impending translocation projects, BRP capacity to intake beavers, and depredation reports that may warrant beaver take.

Where feasible? What exactly does feasible mean? Was Martinez feasible? And in general is the term undefined so that one man’s feasible is another man’s out of the question? What’s “Feasible” in Placer county?

STEPWISE PROCESS FOR BEAVER DEPREDATION INCIDENTS IN CALIFORNIA

Confirmation of depredation. Per Fish and Game Code section 4181, a
beaver depredation reported by the reporting party (RP) must be verified by a
Department responder.

  1. Responders will collect the following information:
  2. Full description of the property damaged, destroyed, or immediately threatened, including pictures as available, and the date(s) occurred.
  3. Method of identifying the species suspected of damaging, destroying, or threatening

Description of nonlethal or less-lethal measures used to prevent beaver damage prior to requesting the permit.

  1. If the location of the property with reported damages is located within the known range of a species listed pursuant to CESA or ESA (see 3b).
  2. Responders will assess if the damage to the property pose an imminentthreat to public safety.
  3. If the responder determines that the beaver activity poses an imminent threat to public safety (e.g., catastrophic infrastructure damage), the responder, in consultation with their chain of command, may prioritize issuance of a depredation permit uponrequest of the RP. The responder, at their discretion, shall add termsand conditions to the permit necessary to protect wildlife and ensure public safety.

Allow me to say here that Martinez would have claimed there was an imminent threat to public safety and that trapping was the only way to prevent terrible flooding that would have destroyed roads and infrastructure and ruined our downtown.

They would have been LYING. How do you plan to rule that out?

Education.

To help reduce requests for permits, the responder shall first educate the RP regarding beaver behavior, ecology and ecosystem benefits, and site-specific options to mitigate beaver damage.

  1. Responder will have reasonable situational awareness, such asunderstanding of relevant research, population dynamics, co-occurring species, habitats, or natural communities that may be impacted, as well as any other pertinent factors.
  2. Responder shall provide the RP options to institute logistically and economically feasible corrective actions to prevent future occurrence ofthe beaver damage. The concurrent use of multiple methods is recommended.
  3. Potential actions may include, but are not limited to:
  4. Install water-flow management devices (e.g., flexible pond levelers, Clemson levelers, “beaver deceivers”, “Beaver Back-Saver Device”).
  5. Install trapezoidal fencing with or without pond leveler device attached.iii. Install cylindrical cages, exclusion fencing (e.g., electric fence,hardware cloth around trees).

This is better known as the TRY SOMETHING, TRY ANYTHING clause. Which I suppose is dimly better than not trying anything, Saying that you should use a Clemson or a Pond Leveler or cotton balls and duct tape reads as if their both the same amount of research and effectiveness. There is no recognition of the fact that using a well understood tool with a proven track record is in fact better than using one that’s so outdated people don’t use it anymore.

  1. Deploy repellents (e.g., coating trees with paint/sand mixture).
  2. Eliminate local attractants (e.g., gardens, crops, lush vegetation).
  3. Install cylindrical cages, exclusion fencing (e.g., electric fence, h ardware cloth around trees).
  4. Deploy repellents (e.g., coating trees with paint/sand mixture).
  5. Eliminate local attractants (e.g., gardens, crops, lush vegetation
  6. Subject matter experts may be consulted to help identify appropriatenonlethal measures and corrective actions.

WE LIKE Step 6! Can we make step  6 Step 1 and forget the Clemson? Can we please give rp’s extra credit if they actually follow that step? And cam we make cities that  wrap trees with orange plastic an automatic fail? (I’m looking at you Bakersfield).

RP requests a permit. If the RP requests a depredation permit, the Department may issue a revocable permit that authorizes take of the animal(s) by the permittee and their authorized agents, pursuant to FGC section 4181 and CCR section 401.

  1. Consistent with Fish and Game Code section 86, “take” means to hunt,pursue, catch, capture, or kill, or attempt to hunt, pursue, catch, capture, or kill.
  2. Responder shall provide technical guidance to reduce the risk of incidental take of a non-target species.  If the BRP has communicated with HWC staff or wildlife biologists that beavers are needed for an approved project, the responder will consult BRP staff to determine whether to request voluntary cooperation from theRP to live capture/relocate the depredation beaver(s). This action wouldoccur in place of issuing a permit. If there is no active request for beavers,BRP consultation is not required.

Terms and conditions of permit.

The Department, at its discretion, shall add terms and conditions to the permit necessary to protect wildlife and ensurepublic safety, including but not limited to conditions that require the permitteeto implement corrective actions to prevent future damages.

The rest is pretty much the same. You know it by heart. Permit issued for a specific period of time, blah blah blah. For my money the best parts of this are actually writing down that beavers are important to California and saying that landowners must be provided with some basic education about beavers when they seek permission to kill them. I’m actually not sure what this will change in practice, but we’ll see when we look at the numbers again later this year.

I’m going to bet the will be LONGER descriptions of what they tried to do to solve the problem some of them actually useful, fewer unlimited permits issued and a smaller allowed take overall, but close to the same number of permits granted.

We’ll see.

 

 

 

 


On Monday EBRP came with a crew to work with city staff to figure out how to fill the mobile fish tank at the festival. Last time we had to use the fitment in the park and it took forever. This time staff was friendly and helpful and very enthusiastic about the event. They will fill it from the corner fire hydrant which will take about 20 minutes. Honestly I got my signed permit for the event back and every single signature was a new mostly friendly face.

It feels like I’m living in a brand new city.

The children’s choir VOENA that will be starting the festival day played at the Lesher theater in Walnut Creek last month. Apparently they were a big hit.


Well that’s it. This is the big one. What we’ve been waiting for. I think I know what film clip this calls for.

New CDFW Policy Recognizes Ecological Value of Beavers in California

The California Department of Fish and Wildlife (CDFW) has implemented a new policy recognizing the ecological benefits of beavers while mitigating conflict over damage to land and property (depredation). CDFW’s new policy builds upon its existing beaver management policies and lays the groundwork for projects that harness beavers’ natural ability to help protect biodiversity, restore habitat and build wildfire-resilient landscapes. This includes a process that enables beaver relocation as a restoration tool and a new non-lethal option. The policy also outlines a process to mitigate beaver depredation conflict, prioritizes the use of nonlethal deterrents whenever possible and ensures that lethal removal of depredation beavers is done in a humane manner.

You got that Timmy in public works and Susie in the field office?  Those beavers you are worried will flood your drain system belong to the people of California and have a job to do. You are going to need to solve that problem non lethally and show us that you tried in a reasonable way to do so before we talk about any depredation.. And that doesn’t mean writing “Hazing” on your permit application. Because that’s not reasonable.

The new policy, signed by CDFW Director Charlton H. Bonham on June 5, is available on CDFW’s beaver web page. Here are a few key take-aways related to depredation permits:

    • CDFW shall document all nonlethal measures taken by the landowner to prevent damage prior to requesting a depredation permit.
    • CDFW shall require implementation of feasible nonlethal corrective actions by the landowner to prevent future beaver damage.
    • CDFW shall determine whether a property is located within the range of listed species and add permit terms and conditions to protect native wildlife.
    • CDFW shall continue to prioritize issuance of depredation permits if it determines that an imminent threat to public safety exists, such as flooding or catastrophic infrastructure damage.

“Beavers help improve habitat restoration and water quality, restore ecosystem processes and bolster wildfire resiliency,” said Director Bonham. “This new policy formally recognizes beavers as a keystone species and ecosystem engineers in California. They are truly the Swiss army knife of native species due to their ability to provide so many nature-based ecosystem services.”

Beavers, the animal that doubles as an ecosystem, are ecological and hydrological Swiss Army knives, capable, in the right circumstances, of tackling just about any landscape-scale problem you might confront. Trying to mitigate floods or improve water quality? There’s a beaver for that. Hoping to capture more water for agriculture in the face of climate change? Add a beaver. Concerned about sedimentation, salmon populations, wildfire? Take two families of beaver and check back in a year.

Ben Goldfarb

The swiss army knife of native species. Who was it that used that phrase again? Oh right, that would be a direct quote from Ben Goldfarb Penn award winner in Eager: the secret surprising lives of beavers. Ben-with-his-pen created a metaphor that changed California policy.

Not just any old metaphor could have done it, either. He didn’t say they were the hydrological silly puddy, or corkscrews or duct tape that could fix every problem. He specifically chose a metaphor that conjured up treasured boyhood memories that every single member of CDFW holds dear. (Even and especially the girls). Holding a new swiss army knife, opening a shiny red swiss army knife, even having one hidden in your pocket after returning from a camping trip connected their younger selves with everything that was possible in their world. When you have a swiss army knife to rely on you do just about anything.

Ben handed CDFW a ‘sense memory’ of potential accomplishment. And with it they accomplished something huge.

CDFW is committed to ensuring that humans and beavers can safely coexist when and where possible, and continues to prioritize communication, staff training, public education and outreach to reduce human/beaver conflict. CDFW staff will provide technical assistance to landowners to prevent future occurrence of beaver damage. In 2020, the CDFW Human-Wildlife Conflict Program created a comprehensive online Human-Wildlife Conflict Toolkit that includes accessible resources with logistically and economically feasible options to help property owners prevent damage due to beaver activity.

The other key word is NATIVE SPECIES. Which was only able to happen because of OUR historic California beaver articles. Thank you Chuck James for laying the foundation for them and Rick Lanman for making them spring to publishable life. This whole day is a reminder that the Pen is mightier than the Conibear!

On May 24, a consortium of advocates representing the Beaver Policy Working Group and the Placer Land Trust hosted a field trip for legislators and agency representatives including CDFW to Doty Ravine in Placer County to see beaver restoration at work. The field trip served to highlight the state’s Natural and Working Lands Climate Smart Strategy (Executive Order N-82-20) in action.

The California Natural Resources Agency’s YouTube page features an interview from the field trip (Video)(opens in new tab) with CDFW Beaver Restoration Program Manager Valerie Cook.

Doty restoration project would never exist without the mindblowing effort of Damion Ciotti from USFS who had the dogged and gentle persistence to make it happen in the county that was least inclined to cooperate with beavers in the entire state, And its possible that our consistent review of depredation permits pointing out that Placer was NUMBER ONE in beaver killing  that  got me eventually invited to the fish and game commission in Placer which was VERY ANNOYING but which Damion actually attended and spoke up afterwards planted the seeds that grew into Doty in the second place.

On May 25, CDFW hosted its first virtual informational meeting (webinar) to celebrate the formal launch of the new Beaver Restoration Program. More than 250 people including media outlets attended this webinar to learn more about this historic program. Program staff will collaborate with diverse partners to translocate beavers into watersheds where their dams can help restore hydrologic connectivity, ecological processes and natural habitat. A recording of the webinar is available on CDFW’s beaver web page under the “Beaver-assisted Restoration” tab.

Well, at the time I wasn’t overly impressed with the meeting and thought the very best part of it was the fact that Bonham’s right hand man called beavers swiss army knives. Which implied that he actually read Ben’s book and learned something in the process.

And, what do you know, it turns out I wasn’t wrong.


Two get a ride- Rusty Cohn

Last night Rusty photographed a beaver giving and receiving a piggy back at the same time. Reminding me of some amazingly stacked toy where children can pile beaver on the back of beaver like elephants holding tails.

I just don’t know, do you think they’re cute enough?

Maybe if they were just a LITTLE cuter or had faces like raccoons or hung out in eucalyptus tree like Koala beavers they would have a chance of convincing people not to kill them. Maybe if they came out in the daytime or during traffic or only during parades people would understand how adorable and useful they are.

I mean it’s not enough that beaver ponds save water or prevent fire or reduce flooding or help salmon or increase birds or increase amphibians or remove nitrogen or clean the water, All that just isn’t enough.

So maybe if they were cuter?
