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

Category: Urban beavers


frontpieceYesterday two lovely copies of Gerry Wykes beautifully illustrated tale of the Detroit River beavers arrived in the mail. I can’t tell you how excited I was from the moment I opened and saw the striking frontspiece showing in part above. The first lines reminded me instantly of the Martinez Beaver story and the surprise with which people reacted to learn that beavers were lurking in their midst. But the tale continues with such a local sensibility to the particular meaning for this very urban river, that it was even more exciting.

The folks at the Conners Creek powerplant on the Detroit river were alarmed at first by some disappearing trees, which they attributed to vandalism, accident, or possibly Big Foot. The book makes a wonderful point of explaining that no one in their right mind would think the theft was the work of a beavers, since there had been no beavers in the Detroit river for 150 years! And just in case you’re wondering what America looked like then, Andrew Johnson was president (following Lincoln’s assassination) and in 1866 ‘negroes’ were officially recognized as American citizens.

Beavers came back to a very different Detroit river than the one they had been trapped out of.

The disappearing-tree mystery was solved with the help of a team of experts including Jason Cousino, who saw the remaining stumps and knew enough to install a night camera on one of the felled trees. Sure enough, a BEAVER was filmed returning to finish his hard night’s work. The city was elated, everyone merrily took credit for cleaning up the river. and it was even reported on Regis and Cathy Lee. Surely if the polluted Detroit river could make a comeback, anything was possible.

A Beaver Tale: Gerry Wykes

The hardworking beaver paid no attention to his fame, and set about making a massive lodge that from almost nowhere attracted a mate. To everyone’s surprise in the spring of 2009 kits were born. The author does a commendable job making the science of beavers, their adaptations, their life history, and even the fur trade exciting and accessible. Even though it’s written for a younger reader, I’d be fairly happy if every city official knew as much about beavers as they read in this book.  Even the details of complex concepts like “coppicing” of trees are delightfully explained.

I adore this illustration in particular. (The colors are so vibrant and inviting I’m wishing it was the pattern on my bed sheets or kitchen towels.) In addition to the inviting animals, Wykes does a impressive job of showing the hardened urban skeleton they moved into, right down to the smokestacks and abandoned houses. His artwork beautiful captures the fragile resilience of “nature in the city”.

The representations of beavers are wonderfully accurate. He really captured all the parts of their lives  in his illustrations. I’m not sure where the author gained such a fine familiarity with the beaver shape, shading and movements – but this gives me a little idea:

There a few little mistakes we could have set him straight on if he had asked, like writing that beaver need Cottonwood or Willow to survive.  Not true. Beavers LIKE those trees, but they can survive on a host of others including (but not limited to) Alder, Aspen, Maple, Oak, Elm and Fruit.There are even places like the Delta (the spot of historically the largest beaver population in California) where they survive without TREES – existing on Tule roots and cattails. He also mentions that folks came to America looking for the other kind of gold and were surprised to wind up with beaver gold. Which I suppose might be true for Columbus, but since we know even the pilgrims were hungry for cheap beaver fur, doesn’t sit right. It certainly doesn’t adequately describe the ruthless resource war that was taking place across this land for a century as folks sought out the ever-shrinking population of remaining beaver pelts. pilgrimbeaversThere, of course, could have been LOTS more information about the way that beavers help fish like salmon and trout, or wildlife like otter and mink, or herons, frogs, turtles and bats while helping rid streams of pollution. But, I’m picky. I admit it. Maybe I’m like the snobby wine connoisseur of beavers?

Regardless of those minor points, this is a beautiful book and worth holding in your hot little hands. It’s perfect as a gift for a curious youth or that nosy sister-in-law that was so interested in the sudden arrival of the curious Martinez Beavers. It goes on sale in March and is available from the publisher for 18.99. OR if you’re very lucky indeed, and no one gets there first, there will be a copy in the silent auction that you can claim for your very own.

Thanks Gerry and Wayne University Press for a truly delightful read!


The grand plan in Vancouver is sweeping the media at the moment and there are plenty of follow ups to the story if you want to see them. Try here and here.

Yesterday I was contacted by a member of the Grosse Ille Nature and Land Conservancy about the beavers in the Detroit River. She was very happy about what the return meant, and wanted to pull together some advocates to keep things headed in the right direction. The funny thing was, I remembered writing about this back in 2012 and saying: sure they’re happy now, but wait until those beavers start chewing trees of blocking culverts.

Beavers: marginally better than pollution!

Ahhh how Nice. Okay, mark your calendars and set your clocks, because as encouraging as this article is I predict it will be a matter of months before we start reading stories about neighborhoods with blocked culverts and chopped trees. Folks are excited when beavers come BACK to an area because they assume it means they did very good things to make it possible. Hughlet Hornbeck once explained to me that the beavers coming back to Alhambra Creek was proof that EBRP had been doing the right thing for 50 years, for example.

Then industrial pollution in the mid-20th Century made the Detroit River too toxic for beaver and many other species to return. The cleanup of the river in recent decades has seen many species making a comeback.

“This is one piece of evidence,” Hartig said of the latest beaver sighting. “But if you add in there the return of lake sturgeon, the return of lake whitefish, the return of walleye, the return of bald eagles, peregrine falcons, osprey, beaver, wild celery, it’s one of the most dramatic ecological recovery stories in North America.”

Beavers are still exciting enough along the Detroit River that the reporter does an excellent job researching their history and providing context.. Enjoy it while it lasts though, because in the blink of an eye they’ll be reporting that gangs of four foot tall beavers cut down all the trees and caused tularemia.

So it’s been three years and its time for folks to get worried about their challenging handiwork, I’m glad friends are starting to get ready for an argument. We of course will help any way we can.

Speaking of helping, I got these fun photos from the Mountain House beavers in CA, and will be working with a supporter to help her put together a beaver article for the local paper. How cool are these photos for thinking about urban beaver!

Yesterday I learned that the city’s primary concern is that they believe the beavers are digging tunnels under the road. The city has already filled some with concrete. For the life of me I can’t think of any reason a beaver would do THAT, so I’m guessing this story is about to get very interesting!

New donation yesterday for the silent auction from Mink Works, by animator and Illustrator Marielle Rousseau of New York. How adorable is this? I ask you honestly. Go check out all her stuff. It’s delightful and she’s a self-professed wildlife lover in addition to being a real talent,


This looking up ‘urban beavers’ thing is producing some amazing results. An awesome article on several  beaver habitats in Dallas Texas, with what is quite possibly the best urban beaver photo I’ve ever seen. I’m a sucker for curved dams in the country or the city!

Beaver – Population Density

For this project we explored two stream beds for the purposes of observing and documenting evidence of Beaver activity. The small creeks we chose were located at opposite corners of an approximately six square mile rectangle of suburban North Texas.

Beaver sign was abundance and easy to find in these areas. The evidence we found included felled trees, dams, lodges, slides, and Beaver skeletal remains. We found a total of five dams in the areas we explored—four active and one that had been recently destroyed by people.

Isn’t that remarkable? Beaver dams all over Dallas just trying to save water for the poor folks in Texas. Apparently the author of this blog is a well known local naturalist and colleague of our beaver saving friends in the area, so I’m pretty excited to have more voices on our side. Let’s remember this site.

CaptureNext up is an UNBELIEVABLE article on urban beavers from  Seattle. I was absolutely floored how delightfully relative this was and could NOT believe I had failed to remember writing about. Surely I couldn’t have missed it?

Then I noticed the date. About 4 months before my time.

Meadowbrook Pond: A beaver playground

Thursday, August 24, 2006

“This is the Disney World of beavers,” said Bob Spencer, creek steward coordinator for Seattle Public Utilities, as he looked out over Meadowbrook Pond in Northeast Seattle. Fuzzy mallard ducklings and great blue herons were playing second fiddle to the obvious star attractions: several of North America’s largest rodents entertaining an enthusiastic crowd of visitors.

“Beaver! Beaver! Beaver!” three kids shouted in unison to their dad who hurried over to watch a large furry brown head tote a leafy branch to the edge of the lodge.

“These hip, urban beavers have kind of gone condo,” Spencer said, pointing out their home, a jumble of materials ingeniously supported by the bridge turned wildlife viewing platform, which spans this detention pond. A large dent in the handrail shows where a broken alder located midway across the water fell under their sturdy front teeth.

Spencer has found that, like Ryer, even those with beavers in their backyards are excited to be living among them: “Seattleites regard having beavers back as a sign that something is getting better.”

Every single word could have been lifted from Martinez. Right down to the excited children and using the bridges as viewing platforms. I’m sure we’ll revisit this article again, but for now go read the entire thing and imagine it as a trailer for our own beaver movie that was coming soon.

One last treasure I could NOT believe finding were these promotional/educational tools from PBS. Theoretically released to coincide with the beaver documentary, but missed by me and countless others. I vaguely remember Jari talking about the plan for these, but I think they were delayed or something.  When I shared them on facebook yesterday there were 25 immediate shares from beaver experts who had obviously missed them too.

So we know it isn’t just us. Whew.

I’ve been snooping around a bit on the subject of urban beavers, and came across this fun report from the city of Akron Ohio. True, the emphasis of the article is that you can hire us because beavers move into urban spaces and we’ll remove them – but the pictures are fun. And so familiar to us in Martinez that I thought you’d smile.

Beavers Adapt to Urban and Suburban Environments

Do you think beavers only inhabit pristine wilderness areas? If so, we offer these pictures and blog entry to shine some light on the very adaptable nature of beavers. All it really takes to have beavers move into your neighborhood is a waterway and some trees.

The following series of pictures documents a beaver colony living (and thriving) in an urban area of Akron, Ohio. Industrial sounds and smells…littered plastic bags and styrofoam cups…the rumble of freight trains…all just par for the course for this beaver colony.

Taking a walk toward the beavers’ hut, one of the urban beavers is spotted. With a water intake for a chemical processor on one side and an industrial complex on the other side, an adult beaver swims down the waterway to get a bite to eat.

Closer towards the hut, there happened to be a tree which took root precariously between two railroad trestle foundations. In spite of the graffiti (included for realism, not offense) and train traffic, the beavers apparently like to hang out under the bridge and get their gnaw on.

Yes, beavers have adapted to urban environments. What’s your point? So have foxes and crows and raccoons, to name a few. If they hadn’t all adapted they’d be in a mess of trouble. Because our environments are overwhelming urban in this day and age. 81% of humans live in these urban spaces. So I’m sure the stats for beavers are similarly high.

Just a little further up the canal and the main hut is visible. As you can see, this is a large and active hut. There is an ample feed bed (all the sticks in the water in front of the hut) as the beaver family has made preparations for ice cover. A smoke stack and large industrial site are close by in the background.

On the walk back to the car, the beaver that was out for a swim is found perched on a log having a meal of some underwater vegetation. This beaver was not very skittish of human presence: we were within twenty feet of it. It kept its eye on us, but we never got the tail slap we were expecting. To us it seemed as conditioned to human gawkers as it does to its gritty urban environment.

We get it. Beavers in urban settings with plastic cups and trains. Smoke stacks and pavement in the background. Understood. Did you know the beavers of Martinez once used a golf club in making their lodge? And because of our unique homeless population, we pulled not one but TWO prosthetic legs off the dam?  When a city lives along side beavers it benefits by having increased wildlife, better birds and cleaner water. Do you know any cities that wouldn’t like that?

And I hate to tell tales out of school, but that beaver in your photo is kind of ugly. Ours are much prettier next to their plastic cups.

Another enjoyable urban find is this video  of someone who was surprised to see beavers in their city. Listen to the narration, her companion is positively terrified. She writes of the incident thusly: Just 5 blocks down the street on my way to Starbucks I noticed damage on the trees apparently from beaver activity… yes, I believed to be crazy at the time, but today, coming back from Starbucks with Patrick we found this one that you can see and a second one we couldn’t catch on camera, but it’s real, we have beavers! and I guess that is fantastic! regards.
