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

Month: December 2010


Consider the River Otter (Lontra canadensis). Cheryl snapped this photo of the visiting fish-eater near Starbucks yesterday. Otters have huge territories so he/she has lots of different feeding spots to choose from but the Martinez Beaver Ponds are definitely on the  short list. Since beaver dams trap organic material that insects break down, they increase fish populations and become feeding grounds for lots of wildlife.  Remember that in the fall we saw mom and junior visiting the area so that she could show him where to find easy fishing once he was on his own. Observers say the otter was showing his/her talents with fearless aplomb yesterday, popping out of the water to savor each victory.

I dearly wish we’d see an otter family someday, with little pups. Otters start out life much more slowly than beavers, not learning to swim until they’re 8 weeks old! Pregnant females raise their pups entirely by themselves, with no help from Dad, who will fertilize anything he gets his paws on. Otters can’t dig their own den, so rely on other animals to do it for them (hint, hint). Once an otter is impregnated it can delay implantation of the fetus for up to 8 months, timing the birth for the spring.  But in the mean time we are always delighted by an otter vist. A special benefit of this photo is the glimpse of his curving, tapered fur tale.  If you’re still not sure you can tell them apart from beavers, this might help:

In solidarity for our frozen East-Coast friends today I thought the website should snow, too. Enjoy!

Beaver Guru Mary O'Brien sent this this morning

Cheryl went looking for our ‘fancy ducks’ this morning and sends this photo of last nights beaver-chew party. She says everyone enjoyed the otter putting on a show at Starbucks and up and down the creek, catching big fish each time he dove. Photos to follow!

Hooded Merganser at beaver dam: Justin Watts 12/23/10




Check out our new Christmas visitors to the dam site! It’s a male (left) and female (right) pair of hooded mergansers. These are obligate nestors who may have come to inspect the wood duck boxes Mitchel installed. If we’re lucky they just might stick around. A trio of young birds came on valentine’s two years ago I’m guessing they were emissaries checking the place out. Apparently they liked what they saw.

Here’s hoping we see these someday….


My Dad was at the dam at dawn but saw no beaver ripples. I guess the family is busy inside the lodge opening their presents.  Just in case you don’t recognize the tree below, its willow frozen up!


Last night while we kept watch for beavers at the secondary dam where they’ve been recently spotted, they sneaked to the primary dam and gave a much awaited show to a young couple who had driven all the way from Modesto just to see them. They reported an adult and a kit but we don’t know if they saw Dad or GQ.

Meanwhile we were treated to a silent movie of the luckiest green heron ever who caught a MONSTROUS fish that was easily a third of his body length. He sat with it trapped in his beak for a long while, afraid to move it into swallowing position for fear it would get away. Then he embarked on the impossible task of turning it around working it into his throat, shaking the banana sized wriggling thing into his stomach. We saw the fish become a tail and then nothing at all.

For a moment after that the bird looked down at the water as if he still ought to find more fish. Then he seemed to feel the moving weight inside him and think better of it. With a repose worthy of an antacid commercial (“I can’t believe I at the whollllle thing”) he sat very still in the dark for the rest of the evening.

Have an excellent day what ever you do and here’s a little tradition I’ve grown very fond of.

No, I’m not kidding. Maybe you aren’t convinced by this whole ‘beavers make habitat for birds/salmon/wildlife’ argument. Maybe you don’t care about raising the water table or combating the drought effects of climate change. Maybe you need more proof that beavers are worth all the trouble they cause to keep around. Have I got the Christmas Eve-Eve story for you!

Beaver dam helps contain oil spill into Greer creek

GREER — A heating oil leak from the basement of the former Allen Bennett Memorial Hospital is expected to have cleanup crews working today to remove the oil from a creek where one resident said a remarkably well-constructed beaver dam stopped much of the spill.

So the leak happened on Friday but no one noticed it until monday of course and the mysteriously named ‘number 2 fuel oil’ was mostly stopped at the beaver dam and didn’t pour into county water sources.

How much oil leaked into a tributary of Frohawk Creek, which feeds the South Tyger River,won’t be known until the contractor tasked with the clean-up finishes and a report is completed,said Thom Berry, spokesman for the state Department of Health and Environmental Control.The city engineer and a coordinator for the Environmental Protection Agency estimated between1,000 to 1,500 gallons had leaked.

The article praises the watertight engineering of the beaver dam and says it saved the town lots of money. I’m always happy when beaver dams get good press but of course I’m  concerned about the beavers. There is no indication that the environmental firm hired to take care of the spill has any intention of dealing with them. Obviously the beavers needed to pass through the oil to breath, so theres no way they’re not coated too. I can imagine, with grooming habits, that they have rubbed that toxic sludge all over every part of every family member by now. Temperatures in Greer are dropping below freezing at night and these beavers need their fur in good working order to survive.

I wrote the cast of characters and spoke with Cheryl at IBRRC about it. She said the most knowledgeable voice in oil clean-up out that way is Tri State Bird Rescue. These beavers need to be live trapped, cleaned and re-released.  Their dam probably needs to be cleaned too because they’re going to keep touching and working on it. Maybe they need to be relocated because the inside of their lodge is likely covered in oil too. My guess is that the environmental crew will remove the dam and the lodge because its ‘toxic’ and give no thought whatsoever to the first responders who depend on both.

Here’s my letter and where to write your own:

Reporter; City Engineer: City Administrator: Department of Health & Environmental Control

I wanted to write and ask how you plan to care for and monitor the beavers whose dam saved your city a great deal of money and inconvenience. A fuel oil slick on the water surface will obviously affect any animal who lives in it. Aside from its obvious toxicity when it sat on the water they swam in for three days before anyone noticed, the oil could reduce the temperature regulation of their fur and interfere with grooming and care for young. I am cc’ing this email to the International Bird Rescue and Research group so they can advise you how to safely treat coated beavers. You will need to live trap them using baily or hancock traps and I would be happy to advise you who to connect with for that to happen.

The beavers did you a huge favor with their dam. It is only fitting you pay them back.
