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

Category: Who’s saving beavers now?


There are lots of reasons to do the right thing.

Because it’s better for the world. or better for the people in it. Because it makes you feel better, Because you made a promise. Because it would hurt someone if you didn’t. Sometimes because its easier or cheaper in the long run than doing the wrong thing.

But one of my VERY favorite reasons to do the right thing is because you saw someone else do it first and it seemed good, and possible and you liked the way it made you feel.

Meet the new beaver peer pressure.

Resident wants beaver traps out of Katzie Slough

Little by little, the Katzie Slough clean-up continues.

Now, a Pitt Meadows resident wants the city to take another step and try to find a friendlier way of dealing with an animal that’s been part of the nation for centuries.

Instead of trapping the beavers, who can dam up water flow in the slough, leading to flooding of nearby land, Jackie Campbell is asking the city to consider another option and pointing to a nearby neighbour as an example.

Port Moody is trying out a flow device or a pipe that will lower the water level near a beaver dam in Suter Brook Creek, by city hall.

I’m convinced that one of the reasons cities are so reluctant to do the right thing is that all the mayors have lunch and swap stories and are afraid it will catch on – next thing you know Concord will want beavers, and then Walnut creek. Doing the right thing is contagious and our friends Jim and Judy Atkison have started a movement.

Campbell acknowledges that such a device will take more time and effort.

“But this is where we want to go to be more wildlife friendly and safer,” Campbell said previously in a letter to the City of Pitt Meadows.

“Many groups and the Katzie [First Nation] are working hard to attract the public to the slough to appreciate and understand all it can be.”

Apart from the cost to beavers, which drown when a trap holds them underwater, Campbell is concerned about the safety of people and their pets along the slough.

“Wake up,” she said.

“The city will suffer the embarrassment of causing this danger to the public for using this tortuous method of stopping beavers. There are new ways to allow the dams to flow. We must learn to live with the wildlife around us.”

Jack Emberly, a local environmentalist, said modern technology is “finding ways to live with them … trying to find a better way, a more progressive way to work with wildlife.”

Hurray for people wanting to work with beavers because its more humane! That’s a great starting place that appeals to many people. But my favorite reason to work with beavers is because its good for us and our creeks and our wildlife. Because humans need clean water. Because it can lead to such important long-term benefits for our water and our planet.

Pitt Meadows operations superintendent Randy Evans said that the city’s flat terrain makes it easy for flooding to occur.

He has asked if engineers would sign off on such flow devices or pipes, but none so far is willing to do so and risk liability from possible flooding.

Such pipes could easily clog up, which could lead to flooding, he added.

“The device, when I looked at them, they’re very specific for certain locations.”

He added that the city tries to discourage beavers by wrapping trees trunks in protective material and by demolishing beaver dams, often several times, in the hope that beavers will move on.

“Trapping is the last alternative that we use.”

Well okay Randy Evans – we expected this kind of quote from you. And I’m glad trapping is your last option. We just need to refine your definition of LAST. How about you try a well-installed flow device first and then if it doesn’t work you can bring in the traps.

It can be your new ‘last’. First try it the right way.

You know, like Chelan sherriff yesterday in Washington state which posted these photos of their work saving the beaver that crossed the road which he wisely guided with a snow shovel instead of his fingers.

Well done officer!

 

 


We’ve talked about Torrey Ritter before. He’s been on our radar a while. Back in April I said about him, “Torrey is a true Beaver Believer who finished his degree at Montana State University studying beaver dispersal patterns and went back for a masters in Organismal biolology (which I didn’t even know was a thing). His wiki page encourages everyone to support your local beavers, so you can tell we’d be fast friends.”

Now Torrey is doing all that good work for the Montana Fish, Wildlife and Parks department. Collecting a regular pay check hasn’t changed his fondness for beavers one single whit.

Leave it to beavers

Beaver benefits

Torrey Ritter, an FWP beaver specialist, says the streams and rivers in the West look very different than they did before Europeans settled the west and brought grazing animals with them. Once the beaver fur trade took off and trapping and shooting beavers became an integral economic puzzle piece, what were once winding, interconnected waterways with wide floodplains gradually turned into straighter, narrower and faster streams.

“Beavers created this really diverse riparian habitat that all these different species could live in,” says Ritter. “What beavers do is spread water out over a much larger part of a floodplain. It seeps through the system much slower and not only benefits wildlife but also agricultural producers and fishermen. Just having those dams in place slows that water down a lot.”

How’s that for an introduction? Not only is Torrey a great beaver teacher, he also manages to capture the attention of an impatient reporter who made space for ALL of this good news in their glowing article.

Beaver dams create wetlands in redirecting the flow of streams, providing healthy habitats for wetland-dwelling species like birds,

amphibians and insects. While they’ve been known to use a variety of different tree types to build their dams, they usually focus on quick-growing trees like poplars and cottonwoods. Those types of trees often sprout multiple seedlings from the spot the beaver chops off, meaning that beaver activity can facilitate the growth of new sprouts.

That means healthier soil, more environment-cleaning photosynthesis and better habitat for other animals, including greater green cover for large game like elk, deer and wetland-loving moose.

See what he did there? He basically just said that more beavers mean better hunting in big sky country. He is tying beaver benefits directly to what he knows matters most. Torrey is smart.

In addition to helping out native plant species and facilitating regrowth, beaver dams also help preserve water quality and quantity. 

The dams, which are porous, act as natural water filters, slowing down streams and helping to remove sediments from fast-moving water. Since the whole point of the dam is to provide a beaver family with a still pool in which to live and hunt for food, slower water means the flow from the other side is cleaner as a result.

Cleaner water, More moose, Better soil. Got anything else?

Slower-moving water also provides greater recharge for nearby groundwater sources. Since the dammed stream takes less sediment with it and meanders more, it allows for greater absorption into the water table and reduces erosion along nearby banks.

What’s more, Ritter says, is that the sediment-catching properties of beaver dams can help streambeds and waterways return to their historical character.

“All that sediment, rather than being flushed down into reservoirs, is caught behind dams and can help rebuild,” he says. “You end up with these complex, multi-channeled floodplains that provide resources for a really large number of species.”

And, since so much of western Montana’s streamflow comes through mountain snowmelt, beaver dams built in mountain streams help to moderate the rate of flow, meaning more water later into the warmer months.

“Dams in the mountains that slow that down ensure that there are longer flows later into the year,” says Ritter. “There’s more of a buffer between the snow melting off the mountains and droughts later in the year.”

Tadaa! You are watching a master at work. Better hunting and fishing. Cleaner water and less drought. What else do you need to convince you? Do you think he’s painting an overly rosy picture? Wait for the next punch.

But no matter the benefits, in some situations simply leaving beavers to their own devices isn’t the best technique. Trapping is an option for beaver management, but the state of Montana requires a permit to trap, and there are non-lethal ways to protect nearby trees and waterways from the effects of beaver inhabitation.

“The problem with trapping or shooting beavers is it’s always a temporary solution,” says Ritter. “Beavers will travel to find suitable places, and they’re always going to show up again in good habitats.”

The best management practices depend on what problems beavers are causing, Ritter says. The two he sees most frequently are flooding and tree damage.

To protect trees, FWP recommends loosely wrapping trunks in wire fencing or hardware cloth. For smaller trunks, slicing a length of PVC pipe and wrapping it around the base of the trunk can help prevent damage.

There are also ways to allow the critters to go about their beaver business, while still preventing property damage or flooding. Flow devices can be installed in streams, especially near culverts or road crossings, to help mitigate the backing up of water due to damming. Ritter uses the brand name: Beaver Deceivers.

These involve threading a flexible tube through notches cut in a dam, then placing a cage around the end of the tube that prevents beavers from plugging the hole. Water flows through the dam and, in most cases, the beavers can still use their home as long as the level of the pond created is still deep enough.

WOW. Not only did he hold this reporters attention, deliver the right message in the right way. He made it sensible and memorable. He came with a good understanding of solutions. Trapping only works for a while. Solving the problem lets you have all these benefits longer. Torrey is OUR kinda guy.

In the future, Ritter says, there’s also a possibility of using beavers to aid in restoration of Montana’s river drainages. By building small imitation dams, planting willows and releasing beavers into an affected area, allowing them to simply do their job creates a double benefit: helping the beaver population to rebound and providing some relief and healing to damaged waterways.

When we reach that perfect beaver future, Torrey, with our clean water and many fish, plentiful flow devices and happy beavers, no one will deserve more credit than you Torrey, who has been such a bright knowledgeable voice in the wilderness.

Hmm, do you have any summer plans yet? Something tells me you’d be a hit at a certain beaver festival!


Dunawi creek is near Covalis Oregon and prides itself in being  a little more ecofriendly than other creeks. In 2012 it reported there was a beaver dam flooding out its ball-fields so it responded by installing a pipe to drain the dam!

(No, really)

Now they brought in an expert to do it even better, This year I’m told the lovingly named “Beaver strike team” partnered with Jakob Shockey of Beaver State Wildlife Solutions and the Benton County Public Works Department to install a flexible leveler. (Is it just me or does this photo look kinda like the cover of an epic romance novel?)

On January 17th, the Benton County Agriculture and Wildlife Protection Program (AWPP) partnered with the Benton County Public Works Department to fund the installation of a beaver pond leveler on Dunawi Creek.  The device should help reduce flooding of 53rd Street near the Willamette Pacific Railroad overpass while allowing beavers to continue to provide important ecological services.

 

The device was installed by Jakob Shockey of Beaver State Wildlife Solutions with help from members of the Benton County Beaver Strike Team.  Oregon State University Productions filmed the installation for inclusion in a future documentary film about beavers.

Whooo hoo! Hurray for the good folks at Dunawi creek, and hurray for Jakob Shockey, who met up with Mike Callahan at the last beaver conference I attended and decided to start a career. Let’s hope this conference sees many more such inspirations blossom across the west. All of a sudden I’m remembering a certain flow device installation that was helped out by our own public works crew lo, these many years ago.

Ahh memories!

Beavers were discussed briefly on the radio yesterday, not with much attention to their ecosystem services, but still in a mostly charming way. I thought you’d be interested in this report from WXPR Morning Edition.

A Glimpse into the Life of a Beaver

Different animals have different strategies for surviving the winter. In this week’s Wildlife Matters, the Masked Biologist gives us a glimpse under the ice to examine the habits of the beaver.


So the exciting disarray on the web edit page was due to the momentous change to WORDPRESS 5 wheeeee which happened to chose this particular moment of my recovery to assault its newness. Everything has changed, and I’m sure some day it will be better, but in the meantime I was able to add a plugin to resist change. So we’ll just be stick-in-the-muds for now.

The good news is Ben Goldfarb has given us a beautiful interview on morning edition. I can’t imagine what life will be like when all this dies down. I truly think his interviews are improving, because nothing was missing from this one either.

Wasn’t that excellent? The smarter the interviewer the more the man shines. Never dull moment in beaver-land, yesterday Port Moody salmon and beavers made the news as well.

Can beavers and salmon coexist in Port Moody?

It’s a rigorous and time-consuming task, but each year volunteers with the Burrard Inlet Marine Enhancement Society (BIMES) collect salmon, fertilize, count and raise thousands of chum, coho and pink salmon.

They baby them, check them for disease, release them into local creeks and Burrard Inlet and educate students and the public about the importance of B.C. salmon.
Why?

“Ultimately it’s about education and ensuring the next generation knows the importance of salmon to the eco system,” says co-founder Ruth Foster.

You knew it was coming. A paper would never talk about advocates for two threatened species unless they could make them fight, like bees in jar, right?

But today, as the carcasses of the last spawned coho and chum salmon rot into the soil or feed eagles, the group faces a new challenge, one that will take some deft diplomacy to deal with.

For BIMES volunteers, a beaver family that has moved into Suter Brook Creek behind Port Moody city hall has generated wide-spread community support.

The idea of a beaver family living so close to human activity is pretty novel, and the family, a bonded pair and one kit, is a testament to nature and beaver determination.

People have an emotional attachment to these creatures, says BIMES president Kevin Ryan, but he hopes the work of a city beaver management plan will also consider the importance of the creek for salmon. “We are looking to find a balance for fish,” Ryan said.

The group points to changes in the creek wrought by beavers, especially a large dam that they believe is too high for fish to jump to get into the spawning grounds between Murray Street and the SkyTrain line. BIMES worries about the effect of tree removal on the salmon-bearing stream because trees are important for shade.

As a keystone species, they say, salmon are integral to the local ecosystem. If they are pushed out, other species could be endangered.

So it’s down to this, is it? The battle of the keystone species! It’s amazing how natural science works differently in British Columbia than it does in any other region. I mean here are all these crazy people at NOAA trying to talk beavers into streams to help salmon and here you are trying to chase them away!

Beaver activity is apparent along the creek. Water has pooled behind a dam, blocking access to a trail, and there are now three dams in the creek and evidence of beavers taking out trees, including one that has been chewed but hasn’t yet fallen over.

But beaver activity in creeks is nothing new, and beavers have always co-existed with salmon, says Judy Taylor-Atkinson, who has spent a lot of time monitoring the beavers and is advocating for them.

“The beavers are part of the landscape. They were trapped out, but now they are returning,” said Taylor-Atkinson, who is a stakeholder in the beaver management plan.

She credits the work of groups such as BIMES for their hard work and dedication for reviving local streams, restoration work for salmon that is now also bringing back other species to the city, such as herons, muskrat, owls and other animals.

It’s a very good think that Judy is so delicate and politic. Because  I’ve gotten crabby in my old age and I would probably just yell at them.

“It’s not one species against the other,” she said, suggesting the city’s effort to create a management plan will ensure this over the long term.

She’s so good. Isn’t she good? Not that it matters all that much when you have scared salmon worshipers at the helm,

“It’s been four decades since we started this work,” noted Rod MacVicar, co-founder of the Mossom Creek Hatchery along with Foster. “What we want to know is if they (beaver advocates) are in this for a long time.”

He has been doing some of his own research and believes the city needs to bring in experts to recommend the best way to deal with both the beavers and the fish.

While relocating the beaver family may upset some, MacVicar said it may be the best way to save the beavers while also protecting salmon in the creek. He’s worried what will happen when the beavers run out of food or, for example, if more trees are knocked down, shade reduced for salmon, or if the family increases in size. Because of a lack of predators, beavers are expanding their territory and the ponds they create can be good for fish but there may be detrimental impacts as well, if salmon can’t get past the dams to spawn.

“We don’t want it to look like it’s us versus the beavers,” Ryan further added. ”We are just looking for some balance.”

You know about balance, right? That’s where I get what I want, and you stop wanting that other thing! I’m just trying to create some harmony here. You know by over-riding science to compromise one species and cherish another. You understand that don’t you?

There may be opportunities for improving the creek and ensuring it can sustain both beavers and salmon. Finding ways to ensure that fish can get through beaver dams to be able to spawn will be the job of the city as it works to establish a beaver management plan that protects and ensures the future viability of salmon.

Good lord. It’s bad enough trying to educate people about how to solve real beaver problems. Now we have to spend time solving imaginary ones too?


As if it wasn’t enough to be on national news, the Port Moody beavers and their hard-working champions have also made it into the local front page. Judy wrote that they had their first, three hour beaver management meeting yesterday with the city, and she is cautiously optimistic. (Given that she is truly Canadian, that I have to say that sounds pretty cautious.)

Can you have PTSD from city meetings? It gives me a total flashback to the tortured days on the beaver subcommittee – every week for ninety days I forced myself to endure three hours of gruelingly polite persuasion. I had to reschedule  patients just to be there. Things started out downright genteel, but by the time the lawyer brought in the stuffed beaver wearing the sign that said “Help me go somewhere else” and the head of public works complained that Jon shouldn’t come anymore because he scowled too much, things had gotten pretty bleak indeed.

Let’s just say I sympathize with the job Jim and Judy have ahead of them,

I honestly can’t tell if I’m proud or jealous that as hard as their job is going to be, it’s certainly easier than ours was all those years ago. They get Adrien to come put in a flow device. 11 years ago there was no one trained to install flow devices at Furbearers because Mike Callahan hadn’t met Adrien at the State of the beaver conference yet. Because there was no State of the Beaver Conference yet. The first one happened the year after the sheetpile was installed. Skip Lisle attended that. There was no one who had gone through this before to talk to about it or offer advice about living with urban beavers. I called Sharon Brown of Beaver Wetlands and Wildlife once and Sherri Tippie once I think, In those dark days, there were in fact three web pages on the entire internet about how flow devices might work, but when I reached out to Beaver Solutions Mike was kind enough to write me back advice from time to time. I was excited to return the favor by offering video clips and encouragement for his DVD, which helped convince him to attend the next conference where he then met Adrien.

This truly is a brave new world. So many worked so hard to move us foreword. Saving beavers is never, ever easy, but its getting better. And I know they are up to the task.

A final note, today should have been my father’s 90th birthday. I just thought I should say that. Happy Birthday, Dad.
