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

BDA’s are very popular with the beaver-curious. No commitment, no surprises, just a fake beaver dam that is totally controlled and designated by you the landowner. By the time actual flat-tailed residents move in the difficult acceptance phase is already over. All that’s left is the sitting back and reaping rewards.;

It’s got to be a little tough when that planted willow starts getting eaten though. Hopefully by then they’re already convinced.

Rancher greens arid site with beaver dam analogs

BRUNEAU, Idaho — Rancher Chris Black is using beaver dam analogs to make his property wetter and greener.

The structures, with their willow walls and intermittently spaced wooden poles, mimic beaver dams by holding back or slowing water. They’re effective and fairly cheap — important in that they can blow out occasionally, just like the real thing.

“Since ’17 when they put them in, that whole stretch now has become continuously watered,” Black said. “The meadows are starting to sponge that water up, and become greener and more alive.”

Black, with help from state and federal agencies as well as volunteers, has been using the analogs on Deep Creek tributary Hurry Up Creek, which dries up in summer heat. The structures help to keep water in the creek longer and raise the water table. About a dozen of the 30-plus analogs planned are installed.

See how good it works? It might be hard to convince a rancher that beaver are his friend, but install a dam with hydraulic posts and he’s your man! Meanwhile much of the west is starting to get the message.

“Most species are pretty dependent on wet meadows and things, as are my cows,” he said. “If you can manage those and create habitat, you are going to have more wildlife and more benefits.”

“This is low-tech, low-cost restoration,” said USDA Natural Resources Conservation Service Sagebrush Restoration Specialist Derek Mynear. “This is not a new concept, but it is certainly taking off here in the West.”

Several places in Montana, Wyoming, Idaho, Colorado, Washington and Oregon have bravely tried BDA’s with excellent results. Only the feather river in poor cowardly little California. Gosh I wish we were all as smart as a rancher. Here’s an examUpload Filesple from up by Ashland.

It’s about dam time

Deep in the Colestin Valley, between a meadow and a rolling oak woodland, there is a creek. And in that creek there is a dam. Willow branches are intertwined with fir logs, creating a structure that spans the width of the streambed. Its base is lined with grapefruit-sized rocks, covered by a thick coating of mud.

It’s a dam that would make a beaver proud, but this one was built by humans.

Last week, Lomakatsi and the U.S. Fish and Wildlife Service created three engineered structures along Gen Creek to slow and spread the flow of water. Using all natural materials, these “beaver dam analogs” are designed to enhance streamside habitat for fish and other wildlife, while reducing further erosion of the creek. They provide many benefits of actual beaver dams.

Send in the humans. It seems like we let them do whatever they want anyway, Let them do some good for a change.

“One of the goals of the project is to slow velocities and encourage water in the creek to more frequently access its surrounding floodplain,” said Dave Johnson, wildlife biologist for the FWS office in Yreka, California. “Historically, before the stream became so deep and narrow, water used to frequently overflow into the surrounding meadow, supporting alder, willow, chokecherry and other plants that created a wealth of wildlife habitat.”

For centuries, beaver shaped the very makeup of the North American landscape. At one point, the United States was covered with enough water from beaver-created ponds to fill an area the size of California, Oregon and Washington combined. When beaver were eradicated during the fur trade, waterways lost their keystone stewards and hydrologic architects.

Fortunately, beaver populations are on the rise as resource managers and private landowners increasingly recognize the essential role they play in ecosystems. In fact, when using beaver dam analogs to restore streams, there is a high likelihood that the restoration efforts will attract actual beavers to move in and maintain the structures as their own.

They say that which doesn’t kill you makes you stronger. Add to that the things YOU don’t kill also make you stronger, if you let them. 

Let beavers make you stronger, California. Come on, you can do it. Just LET them already!

 Good news this morning from Idaho where folks are slowly catching on about the benefits beaver dams can bring to their land.

Beaver dam analogs catching on in Idaho

GRANDVIEW — Landowners and conservation professionals are excited about a new type of woody structure that mimics beaver dams. The benefits are similar — they store water, slow down runoff in streams, and enhance fish and wildlife habitat.

They’re called Beaver Dam Analogs or BDA’s for short.

Bruneau Rancher Chris Black worked together with a number of conservation professionals to install some BDA’s on his private land on Hurry Up Creek, a tributary of Deep Creek.

I think of BDA’s as the gateway drug to actual beavers. A lot of people get excited about them that might raise an eyebrow when an actual dam appeared of its own accord. The BDA softens them up. Gives them the illusion of control. “I started this” they can say comfortingly to themselves.

BDA’s are like starter kits for beavers.

“I’ve wanted to get beaver in here for years but it is an ephemeral stream,” Black said. “There’s enough willows to make good food for them and everything, but there isn’t enough water for them to stay.”

They’ve put in about 10 structures so far, and more are planned in the future.

“They came in and put them in very successfully,” he said. “They’re backing water up, they’re creating habitat for spotted frogs, for sage grouse, for beaver.”

In fact, when the group visited the site recently, a few people got down on their hands and knees and tried to find frogs right away. Bingo! A biologist emerged with a frog in his hand.

Conservation professionals with the Governor’s Office of Species Conservation, U.S. Fish and Wildlife Service, Idaho Fish and Game, and the Natural Resources Conservation Service are all interested in exploring the benefits of using BDA’s to improve riparian habitat and store water.

Want frogs? You need beaver. Want water? You need beaver. Say it with me now.

The emerging technology of using natural on-site woody materials to build BDAs is building popularity in Idaho and the Intermountain West. The concept was developed initially by Utah State University and Anabranch Solutions, and it’s catching on in Idaho.

“It just benefits a whole host of wildlife species and that’s why Fish and Game is really interested in this,” said Chris Yarbrough, habitat biologist for the Idaho Department of Fish and Game. “It’s a low-cost way to get a lot of bang for your conservation buck.”

We needed to figure out how to put these dollars on the ground in the best way possible, and leverage what’s already being done,” said Josh Uriarte, a project manager for the Governor’s Office of Species Conservation in Boise.

“One of the things coming up is mesic meadows, and how to improve mesic habitats, working with the different partners and agencies on how to do that. We need to be strategic in that, not just putting dollars in postage stamp-type areas, but in strategic locations.

Mesic habitat is land with an adequate water source – adequate but not saturating. Beaver meadows on the other hand were described by Ellen Wohl’s new book as similar to the surface of a “waffle iron covered with water”. Patches of saturated soil and protrusions of land seeping through. That is a hydric habitat, The most sustaining and ecologically rich type of habitat we have.

From the restoration guidebook:

Beaver dams create habitat while they are impounding water, but they continue to create habitat even after colonies are abandoned,often in the form of beaver meadows, particularly in more mesic climates

So mesic meadows can become hydric climates with the right beavers in place.

The Hawley Creek project is far more complex in many respects. With about 25 BDA’s in place, it’s been turned into a perennial stream. But the objectives of the project are similar — to improve habitat for fish and wildlife, and work toward providing season-long flows for endangered salmon, steelhead and resident fish.

By holding this water higher in the drainage, we’re not only providing habitat for native fish and anadromous fish, but we’re also providing irrigation water later in the season when they need it as well,” Bertram said.

They had a great many share holders to partner with. This entire project spread across a tapestry of ranchers, BLM land and forest land. Only someone with the patience of a saint and the vision of many beavers could have taken this on.

“At first, they were like, why are you building beaver dams? Once they saw the results, they didn’t want to go build more fence, they wanted to build more beaver dams,” Lohmeyer said.

“By slowing this water down, spreading it out, you can just see the response from the vegetation, the grass growing up, I can hear the grasshoppers in the background, passerines have just exploded, all of the wildlife species and insects have just exploded,” Bertram said. “And we’re already seeing brood-rearing sage grouse coming into this area and utilizing it in the short period we’ve been here. It’s been a huge success story for them, and I’m excited to see how the leks respond over time.”

“These meadows are like a sponge,” he said. “They take that water and they hold it, and release it slowly into the system. So we don’t get that big rush in the spring, when the springs are active, they run hard and then just dry up. Then you just have a dry meadow. With water being held back in the system, it releases slowly, and that benefits downstream users, too, so it’s a benefit for everything.”

What an epic project, with such lasting positive results! When Idaho signs on to the beaver team they certainly bring all their best tools to the table. I’m so impressed.

What we need is some folks to do this work all over California.

Well it looks like someone’s getting a nice fat grant from NOAA to help fish by helping beavers. Ain’t it funny how life works? I mean in Wisconsin you could probably get a grant for destroying beaver dams because you said it would help fish.

Location. Location. Location.

National Marine Fisheries Service grants $15 million for salmon habitat

SALEM — Oregon’s salmon and steelhead bearing streams will benefit from $15 million recently allocated by the National Marine Fisheries Service.

The Pacific Coast Salmon Recovery Fund money, along with Oregon Lottery proceeds, are granted to the state’s soil and water conservation districts and watershed councils by the Oregon Watershed Enhancement Board to improve habitat for species listed on the federal Endangered Species List.

In Wheeler County, Chase Schultz, the soil and water conservation district manager, said the grants he’s received through the Watershed Enhancement Board are used to cool stream temperatures and improve water quality with streamside planting and fake beaver dams.

“Beaver dam analogs are a hot button topic,” Schultz said.

Built from untreated wooden posts driven perpendicularly into the stream and woven with willow whips, the analogs simulate a beaver dam by spreading a stream’s water out into the floodplain, benefiting adjacent wetlands, Schultz said. The analogs also increase stream flow later in the summer, slowing water down that is released longer into the summer and early fall.

The hope, Schultz said, is to create the habitat to attract beavers to move in and maintain the dams.

The best part, he said, is the dams quickly create desired results. Immediately following the 2017 installation of a dam on Bear Creek, a tributary to the lower stem of the John Day River, Schultz said water started backing up and extended a wetted reach almost 2 miles.

You know how it is. Everyone wants the popular kids to sit at their table. Sometimes you get lucky and a family of beavers moves right in and starts doing your work for free. It’s a pretty fine day when that happens, I can tell you.

There’s more good news on the beaver bandwagon because our Idaho friends will be hosting their SIXTH beaver dam jam. Wonderful!

6th annual Beaver Dam Jam to raise Money for watershed guardians

POCATELLO — The 6th annual Watershed Guardians Beaver Dam Jam to support beaver conservation will present music and other activities from 4 to 8 p.m. Aug. 24 at the Mink Creek Pavilion.

The pavilion is located in the Caribou National Forest at the Mink Creek Group Camp Site on South Mink Creek Road outside of Pocatello.

Besides live music, the event features food, a silent auction and a super raffle featuring a boat and boating gear among other items. There will be games and demonstrations.

All of Idaho should thank the heavens for sending Mike Settell to Pocatello and getting this started. He had the vision to  find friends and make this happen. It seems a very long time ago indeed that I first read about Mike getting a grant from Audubon to help in his beaver count. Now he does it with a team of volunteers in snowshoes every winter. And rocks out at the beaver dam jam every summer.

That’s a busy man!

“The event is in (a) great setting with great music and food,” said Mike Settell, founder of Watershed Guardians, the organization sponsoring this event. “We are doing this because beaver do more to help preserve healthy native fisheries than perhaps any other factor, and Watershed Guardians is the only beaver conservation organization in Idaho working to ensure they remain.”

See what I mean? Beavers seem to get the best champions.

Oh and lets throw out one more beaver shout to Jennalee Larson Naturalist Intern at Good Earth State Park in South Dakota. For some reason the Dakotas have always been smarter about beavers than lots of their neighbors. Well, mostly.

Just for Kids: SD Children in Nature

Beavers are known as ecosystem engineers. Ecosystem engineers are animals that create, change, and maintain a habitat. These animals strongly affect the other animals living there.

Beavers make small changes that can really impact their ecosystems. They create dams by removing living trees and using them as a part of the structure. Once they create their dam, a pond often forms which brings an abundant amount of new biodiversity (variety of life). Some birds are unaffected by the destruction of trees while other decline or increase in number. Because the dams create ponds, there is a wading area for birds to thrive in as well as a place to lay their eggs if a dam happened to be abandoned. Reptiles benefit as the beavers create a basking area for them on logs. They also benefit from the loss of trees because the forest then grows new early vegetation and the dam creates a slow moving water which some animals prefer. Invertebrates that prefer slow-moving water start to increase in number

Create a yummy dam out of pretzels for a snack: Use peanut butter spread, marshmallow, or chocolate spread depending on preference. Add stick pretzels to the spread of your choice. Once it is all mixed, give each kid a scoop and have them shape it into their own dam.

First let me praise your very fine attention to beavers and their impact on the environment. Good job, Jennalee. And sure, have the kids make a their own frosted dam or whatever. Mmmm disgusting.  And now that we have established our support. um, can you maybe tell me more about your idea that birds can nest in abandoned beaver dams?

I assume this means you are thinking beavers live INSIDE the dam? And if they move out birds can move in? Or are you thinking that birds can lay their eggs directly on top of the sticks in a beaver dam? I’m not sure that would work out too well, even if they didn’t get predated or roll off into the water….

I received the most interesting email from the forest service yesterday. Something tells me you’ll be interested too. But I’ll let you decide. Just check out that title.

Artificial Beaver Dams Hold Promise as a Restoration Tool in California

 North American beavers were once so plentiful in the Scott River Basin of northern California that the area was referred to as “Beaver Valley” by the first Euroamerican fur trappers who travelled there in the early 1830s. But heavy trapping of the fur-bearing rodent—one historical record reports 1,800 beavers trapped by a single man in one month in 1836 along the two forks of the Scott River—ultimately caused the species to rapidly decline in number. As beavers departed the landscape, so, too, did their trademark dams, which played a critical role in shaping the hydrology of the Scott River and its tributaries. Beaver removal, along with activities like mining, deforestation, road construction, and agriculture, have had major impacts on the Scott River Valley watershed over the past 150 years.

Fast forward more than a century, and the Scott River basin and beavers are, once again, intertwined. In 2014, the Scott River Watershed Council, an independent nonprofit organization, launched an initiative to reintroduce the benefits of beaver dams to the basin by building “beaver dam analogues,” also known as BDAs. These structures, which are made of wooden posts woven with vegetation and sediment, are strategically placed in streams to mimic the effects of natural beaver dams. The streams included in the project flow through private lands and are important habitat for federal Endangered Species Act-listed southern Oregon/northern California coast coho salmon. The council installed the BDAs with the goals of improving instream habitat for salmon, raising groundwater levels, and reducing stream channel incision.

Ohh do you hear that? That’s as near as you’re going to ever get to hearing the USDA singing our song. Savor this moment. Shh it gets better.

To date, 20 BDA structures have been installed at six sites and the council has plans for more. Beavers have been active, or have taken over maintenance, at all of the sites, and agency personnel and landowners feel that beaver populations in the Scott Valley are increasing in number.

“Most of the private landowners involved in this project are ranchers who also grow hay and who have largely positive views of beavers and beaver dams, so long as they do not interfere with irrigation infrastructure,” said Susan Charnley, a Pacific Northwest Research Station research social scientist and author of a case study on the project. “Monitoring data and interviews with stakeholders indicate that BDAs are starting to achieve their goals and are benefitting both landowners and fish.”

The case study report includes a detailed description of the pioneering restoration project – the first of its kind in California – and the experiences of partners and stakeholders involved in it – as well as a discussion of the lessons learned.

Although this watershed restoration project was the first in California, results are showing promise, and other California groups are starting to use this restoration technique. The project offers important lessons for undertaking beaver-related restoration on private lands across the west.

Tadaa!!! The Forest service is installing beaver dams and thinking they do REMARKABLE things for the watershed. And hey once humans start these dams actual beavers come and take them over! Saving water, helping salmon, preventing floods, and will you look at that, raisin the water table so all those hay farmers can water their crop!

I was happy to see this yesterday!

CREATING BEAVER DAM ANALOGS.

There is a CNPS El Dorado Chapter work event Dec 12 in memory of Pat Barron! He had a special love for Wakamatsu and its birds, and that is where we will be improving habitat. We will help ARC (American River Conservancy) in their efforts to restore riparian areas where lost to historic grazing.

We will meet at 10AM at Wakamatsu. Parking is on the east: As you drive Cold Springs Rd from Placerville, parking is on right, just after all the white farm buildings, and before Gold Trail School, We will help weave willow between posts that ARC installs the day before, creating Beaver Dam Analogs (manmade imitation “beaver dams” that help riparian vegetation establish/thrive, just like a real beaver dam would). We will also help with planting native riparian trees.

Elena suggests bringing these if you can: bypass pruners, buckets, and gloves. Please also bring lunch and a water bottle, and to wear appropriate clothes (boots, pants, etc.).

Unfortunately, ARC can not accommodate a rain date. The work needs to be done, and they are busy the rest of the week. So this will be rain or shine! How long the project takes will depend on how many of us are able to come. You are perfectly welcome to stay as long as you can, and leave when you need to (based on either commitments or energy level!). We will try and match duties to all ability levels.

Hope to see you there.

Our beaver friend Janet is on her way to help. Great to know this is happening.
