Neighbors Want Solution For Beaver Dam Flooding

Just up the creek from where the water is backing up is a beaver dam, possibly more than one. It’s just north of Interstate 80 near the Davenport Municipal Airport. A resident who lives nearby and is dealing with water on her family’s land took some pictures. The problem is that the dams aren’t on her property and it’s been a struggle to get something done.

“It’s been going on since April. We’ve had water up to our knees almost,” said Lindsay Andrews. She says last year there was barely any water in the creek at all. Now there seems to be a bit of a beaver problem.

“We’ve seen a couple of beavers. My mother in law seen one. We watched one swim upstream not too long ago,” said Andrews.

Their dams are leaving stagnant water and a muddy mess in area her family mostly uses for recreation but on a regular basis.

“We used to do cookouts, can’t do that. Kids used to ride the trails, can’t do that,” she said, “the bugs are a big concern… Safety is a big concern with the kids.”

My god the horror. Our kids haven’t been outside in 5 months because we’re terrified of the westnile-virus mosquitoes or some such nonsense those rotten beavers have brought into our bright green fertilizer-ruined stream. I have only written about beavers in Iowa once before in 8 years of coverage so that means they aren’t even enough of an issue to hit the news cycle. I’m honestly not hopeful for these beavers, but I dutifully posted my comment just in case some landowner wants to be in touch about options.

The only other comment is about how dynamite will fix things, so I ain’t hopeful.

A better use of our time is the youtube account of Ben Dittbrenner, who’s dissertation on beavers and climate change was mentioned a couple days ago in the news. He wrote back after my comment and said that he is thoroughly enjoying this part of his work, and his close contact with the beavers. He’s particularly struck by what a mollifying effect their adorable presence has on even the most hardened maintenance crew.

Of course Worth A Dam knows all about that. Remember the crane company that put in the sheetpile?

You should subscribe to Ben’s youtube account right away so you see the cool stuff he encounters during his project. I just wish data collection on MY dissertation looked like this!

This video is from our animal husbandry facility. Beavers are temporarily housed as part of the Skykomish Beaver Project. The goal of this research is to relocate nuisance beavers, which would otherwise be killed, into headwaters of the Skykomish River Basin to stimulate habitat improvement and climate change

From the SF Gate, May 4 2011

Tucked in a woodsy canyon in the Hayward hills, the Sulphur Creek Nature Center treats as many as 900 injured and orphaned wild animals every year. A wildlife education and resource center, it also serves as a permanent refuge for several nonreleasable birds and mammals.

1. Sulphur Creek Nature Center

Operated by the Hayward Area Recreation and Park District, this center offers classes, a year-round school science program for teachers and their students (preschool through sixth grade), an Animal Lending Library teaching the responsibilities of caring for a pet, and more. (510) 881-6747. www.haywardrec.org/sulphurcreek.html.

Think Lindsay Museum in Hayward and you’re close. And come this saturday think this:

Beavers are “nature’s engineers” in providing habitat for a diverse eco-system. Learn about this “Keystone Species” from Heidi Perryman, founder of “Worth a Dam” and discover how beavers are “key” to a rich environment.

28273 18yr+ $18

This all came about because one of the folks who used to regularly watch beavers with us is a volunteer there and after years of persuasion they agreed to finally host a program on beavers. I’m kinda surprised it’s so pricey and ADULT ONLY but I’ll try to be worth it, with lots of after hours adult only information!

(I only have on explicit beaver picture, but I’ll eek it out.)

Ooh there’s a new video from the wild beaver folks on the Tay, although I hope the date is wrong. Beavers mating in September means babies in late December? Ohhh just got an email clarifying that the date this was taken was Feb 2. Much better!

We haven’t heard much from Devon lately on the great beaver trapping from DEFRA. If you’ll remember, a slew of citizens and farmers came to the meeting asking that they be allowed to remain.

DEFRA took this opportunity to blow off the meeting and pick up the traps instead. We heard they haven’t been too successful at catching any quarry, and it is looking like the good guys were winning this round. At least by default.

I guess DEFRA thought it was time for this.

Don’t allow beavers to upset our freshwater ecosystem

There seems to be a movement in this country to re-introduce species that have long been extinct, of which the beaver is one of many. These people will support their argument by declaring the beaver has only been extinct for 200-300 years. Not so. It became extinct in this country in the 12th century. As Derek Gow says they are great engineers building dams and constructing homes in rivers and streams from trees they have felled. Derek says they create wetlands. I do not think so. The likely outcome is more floods. Surely we have had enough floods in the last two years without additional problems caused by beavers.

Do not upset the status quo – the freshwater habitat in this country is a fragile ecosystem. Much damage can be done by reintroducing an alien species which the beaver is. We as humans do not have to feel guilty just because we were instrumental in the destruction of the beaver all those years ago. The world has moved on, so has our country and our rivers.

The beaver should be considered an alien in this country just like the grey squirrel, coypus, mink and Japanese knotweed. The damage they can do is too great to take the chance.

Those who put these animals in the River Otter should help the Environment Agency trap them – act now before it is too late.

Alien beavers! Thank goodness the West Morning news printed this ANONYMOUS letter before it was too late! I wonder who penned this thoughtful treatise? (Mr. George Eustice, don’t be so modest!) You should go read the whole thing because it contains a lovely passage from HBN Hynes which makes beaver restoration sound very heroic – and then argues ‘we can’t STAND this much repair in our rivers’! I especially like how it warns us of what’s to come and ends with the recognition that the government trappers have absolutely no idea what they’re doing and need assistance.

(The good news is that I see this morning another very popular badger cull is coming so they’ll have something else to keep them busy for a while.)

Your pro-beaver comment is needed now. I’m particularly of mine.

And just so you know not all of Europe is ignorant of beavers, I got this from Duncan Haley this morning.

The Voronezhsky Biosphere Reserve is pleased to invite you to take part in 7-th International Beaver Symposium! The symposium will take place in Russia, Voronezh, September 14-17, 2015

Organizers of symposium:

MINISTRY OF NATURAL RESOURCES AND ENVIRONMENT OF THE RUSSIAN FEDERATION

Department of State Policy on Environmental Protection

Voronezh Region Government

Russian Research Institute of Game Management and Fur Farming

Voronezhsky Biosphere Reserve

The seventh symposium! And before you start thinking this event is exactly as old as our beaver festival, it’s actually much older, since it’s held every two years. You might remember back when Skip Lisle was invited to the one in Lithuania and our beaver friend Alex Hiller met him there.

Can’t wait to see the lineup for this one!

Hydrologist Andy Bryden (left) and wildlife biologists Molly Alves and Jason Schilling release two captive beavers into a lodge they built earlier on Forest Service land near Skykomish on Wednesday. A team with the Tulalip Tribes worked with state Fish and Wildlife and the U.S. Forest Service to relocate six beavers found near Duvall.

Beavers brought here as part of an effort to improve ecosystems

SKYKOMISH — On a rainy Wednesday, a small team hiked into the woods near Skykomish hauling three heavy cages.Their destination: a creekside pile of cut branches and sticks. Their cargo: a family of six beavers.

The first cage was lined up with an opening in the pile of wood, which is actually a lodge built by the team the previous Friday. The cage was opened and the matriarch of the family, weighing 50 pounds, was gently encouraged into the lodge.

Once she waddled in, one of the team called out, “Mama went in,” and a small cheer went up.Mama beaver was followed by one of her young, then the cage was removed and the lodge entrance blocked to prevent the beavers from leaving while the next cage was lined up.Within 10 minutes, the entire family — mother, father, three subadults about one year old and one kit — was in the lodge, the entrance blocked with a log.

Beavers play an important role in maintaining stream health. Their dams help maintain a consistent base flow of water in streams so that it doesn’t all flow downhill in one springtime deluge, an important consideration in eastern Washington where many streams run dry in the summer.Beaver dams also retain sediment and help to reduce water temperatures in streams, making them healthier for salmon and other fish

Another beaver triumph for Washington state which is the beaver Mecca from which all wisdom flows. I am really happy to see our friend Ben Dittbrenner right at the center of it. He’s one of two folk who replaced Jake Jacobsen as watershed steward in Snohomish county. Jake was my very first beaver advisor, and Ben had lots of chances to learn from the master. He and Jake are both working with Mike Callahan on the adapted flow devices for fish passage. We first met Ben at the 2013 State of the Beaver conference when he joined us for a quick lunch before our talks.

Ben Dittbrenner is a Ph.D. candidate in forest ecology at the University of Washington working with the Tulalips on this project. Dittbrenner said this work will also help prove a theory in his dissertation.

“What we’re hoping to show is that the beavers can be used to reduce the effects of climate change,” Dittbrenner said.One of the major impacts expected from climate change in the Pacific Northwest is warmer water at higher elevations. That will lead to less snowpack, and therefore less water from snowmelt in streams in the summer, presenting risks to salmon and fish habitat.

Beaver activity resaturates the land, however. Stored water migrates downstream more slowly, and often through the water table, which keeps the temperature down.Beaver activity has also been shown to correlate with more stream meanders, more shady spots, and overall more diverse ecosystems, Dittbrenner said. In other studies, juvenile coho salmon were seen in higher numbers in streams with beavers.

“Beavers and coho go hand in hand, or foot and tail,” he said.

Great work Ben and colleagues, and I can’t wait for the day when the work beavers do in smart cities that learn to live with them gets such a glowing article! And that, ladies and gentlemen is why Washington is the beaver beacon for the world.

California, on the other hand, has a LONG way to go. I got back some preliminary data from our statistical analysis of the spread sheets we did on the 254 depredation permits issued in the past 20 months. Apparently we have an “OUTLIER”.

Ya think?

Safari Success

heidi08 Beavers, City Reports, Educational, Environmental, Friends of Martinez Beavers, Who's saving beavers now? September 7, 2014

Last night’s beaver safari was a well-attended, feel-good event, with wildlife-savvy,amiable folk from all over the bay area. Attendees included a wildlife biologist from USGS, my first ever boss (The former director of the Martinez Early Childhood Center), several wildlife-loving older couples from the east bay, a mother from Vallejo with a thoughtful, attentive son, some Martinez regulars who had come to the festival for years, and as a total surprise someone from Jon’s work at the powerplant in Pittsburg showed up unexpectedly! One family from San Francisco ‘dropped in’ because they had made the trek to Martinez that night specifical to look for the famous beavers and knew nothing about any event.

The stars of the evening did not disappoint, (even though Jon, Cheryl and I were thinking sightings were pretty slow and far between in comparison), it was clearly more beavers and closer sightings of beavers than anyone there had ever seen or expected. “They’re so big!” Was the usual first response. “And so close!” There was rapt attention, thoughtful questions, discussion of beavers being important to fish, wildlife, birds, and drought with happy beaver banter well into the night when the group broke up, some of whom went off to dinner on main street. All told we counted about 30 people, 3 beavers and 75.oo in donations offered in the tip jar!

Jon and I drove home reminded of how many truly humane humans there were in the world, which is always a nice way to end an evening. We also thought that there should be a couple more beaver safaris during the year, maybe in the summer months leading up to the festival?

And as an extra special reward, this article was released yesterday in Alberta, which is easily becoming the beaver IQ capital of the country.

How to live in harmony with beavers

A local biologist hopes city and county residents will come to a free talk this fall on how to live with beavers.

The Sturgeon River Research Project is hosting a free workshop on beavers this September in partnership with Sturgeon County.

Laurie Hunt, a biologist with the Northern Alberta Institute of Technology and researcher with the project, says she runs into a lot of landowners frustrated by beavers as her team works to restore riparian zones along the Sturgeon.

“Beavers can be an asset to us, particularly in this time of climate change adaptation,” says Fitch, riparian specialist with Cows and Fish.

Beaver dams can add about 10 per cent more surface water to a watershed and a huge amount of groundwater, helping to maintain flows during dry periods, Fitch says.

“In flood times, think of beaver dams as speed-bumps,” he continues. Beaver dams spread water out over an area about 12 times as wide as the channel they cover, slowing flows and reducing erosion.

Honestly, this is like putting on a favorite jacket you haven’t worn or a while and finding 20 dollars in the pocket. What an unexpected treat! Again it seems we have Cows and Fishes to thank for some really smart work. The ever cautionary Mike Callahan wasn’t thrilled about the mention of ‘perforated pipes’ to lower dam height, noting they are easily plugged by even the laziest beaver. But we can tweak their methods over time. In my experience learning HOW to live with beavers is fairly easy. The hard part is learning WHY to live with beavers, and they already have that elusive motivation in spades.
