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

Month: November 2009


Let’s say (and why not?) that early settlers accidentally introduced an invasive plant that they originally thought was a good idea — great for bees, medicine, and kinda pretty. Let’s say they encouraged said plant, gave the seeds to their neighbors, and were very pleased that it reproduced so well in lots of different areas. The plant grew especially well in wetlands, which they thought at the time was okay too. Fortunately about the time they figured out that this plant wasn’t very good for the animals and the environment there were less wetlands to worry about. Remember, early trapping records say there were tens of beavers for every mile of stream, and when we killed millions of them, we lost much of our wetlands and stopped the spread of that difficult plant.

Two birds. One stone, so to speak.

I’m talking of course about this hideous villain. It’s called “Purple Loosestrife” and has taken hold in the north east and choked out other, kinder plants. Yecch! Brace yourself, the image is pretty grisly.

Trouble is, no one really wants to eat it, it’s hard to pull up, it survives horrific conditions, and it ruins things for the shoreline critters. There’s some effort to introduce a beatle that is controlling it naturally (how could that possibly go wrong?) but in the mean time, guess who the great state of Massachusetts has decided to blame?

Beavers!

Remember, this is a state that outlawed cruel traps in 1996, and has been whining about it since the moment the bill was signed. Instead of using crushing Conibear, snares, or leghold traps, you must now painstakingly catch them in a cyclone fencing suitcase, keep them safe until morning and then shoot them very politely through the head. Oh the humanity! How inconvenient! Even though it is still perfectly legal to kill beavers, and a third of the year you can do so without a permit, and all year you can kill them the old way pretty much whenever any human property is threatened, Massachusetts bemoans the change and says that their population has increased by 60,000 beavers since the law was passed.

Are you following me? Because there are more beavers, there are more wetlands, and (insert horror music here) more pernicious purple loosestrife!

Enter Mr. Glenn E. Krevosky of EBT Environmental Consulting. He has a theory, and like all good theories, it blames the rodent. He says that beaver dams cause flooding, destroy native plants and then make space for Loosestrife to take over. If there were fewer dam beavers, (he has persuasively shouted to the media), we could rid ourselves of this purple menace once and for all. Of course I went immediately to research his copius studies proving this brilliant hypothesis, and saw that the sum total of all literature published in peer review journals on this theory is zero. No research whatsoever. Nada. Not that this has troubled the media, mind you. They are perfectly happy to write down what someone from a very environmental sounding  company says. (Of course I couldn’t find EBT consulting either, so who knows what E.B.T. stands for? Everybody Blames Them?)

Here’s the thing: no one’s studying this, so no one knows. From the University of Michigan

Although there are some studies concerning purple loosestrife’s superior competitive ability compared to other wetland species, there are surprisingly few field or laboratory experiments that identify the traits that contribute to purple loosestrife’s competitive success or that monitor its colonization inspecific habitats over time.

Still, a scientist like Mr, Krevosky can’t let little things like facts stand in his way when the future of crushing traps is at stake. He “believes” beavers are responsible for the increasing loosestrife population. This is still America isn’t it? We are all entitled to our beliefs! One might object to several papers printing his unproven beliefs as if they were fact, but why quibble? I may have my own belief that the more bad things he says about beavers the more likely he is to close difficult consulting contracts with Fish and Wildlife or  Public Works, but the important thing is to share our beliefs. Right?

What would make a blogger bold enough to write this article in defense of beavers? How could I know more than the owner of an environmental consulting firm? Just who in the heck do I think I am anyway? Ahh…Guess what the University of Michigan says prevents propagation of the species? Ah go on, guess. Flooding. Turns out that plant can’t make babies under water. Flooding an area for an enduring period of time is listed as one way to get rid of the plant and discourage new growth — like when the water level is raised from a dam, for instance.

Just sayin’.

So tomorrow will be the  ceremony for the John Muir Association Conservation Award. It will take place downtown, at the Campbell Theatre and be hosted by Lee Stetson, the actor who played the affirming voice of John Muir in the Ken Burns documentary series. Awards will be presented for best organizational contribution (East Bay Regional Parks) best education contribution (David Loeb, publisher of Bay Nature), best business contribution (T. Marzetti Co in Ohio) and best individual contribution (Jeff Alvarez of the Wildlife Project).

Regular readers of this blog will recognize Jeff’s name as the biologist who had volunteered to help us with our interpretive signs grant way back when. Jeff has been an enthusiastic supporter for beavers and Worth A Dam, and will be joining our meeting this weekend to talk about upcoming projects. We couldn’t be happier for him or more excited about our work together. Here’s the press release regarding his much-deserved win:

Named Conservationist of the Year, Jeff Alvarez will be recognized for his lifelong advocacy for wildlife and habitat conservation. Alvarez is the owner and Chief Biologist for The Wildlife Project. His prodigious volunteer work on behalf of wildlife and the environment goes well beyond his business interests. As a volunteer, he has trained professional peers in federal permitting issues for special-status species in order to increase the number of qualified biologists able to work towards the conservation of threatened and endangered species in California . He has lent his expertise, as a volunteer, to assist the Agricultural and Natural Resource Land Trust of Contra Costa County, the Biological Field Studies Association, the Mt. View Sanitation District, and many others. He has created and published techniques for surveying wildlife that minimize impacts on the wildlife. His articles on special-status species have been published in scientific journals, and he shares his expertise by providing gratis presentations on natural history and wildlife management to public agencies and nonprofit organizations. Alvarez is currently fulfilling a ten-year volunteer commitment to assist CASA Avian Support Alliance in Belize with the assessment of reforestation and avian populations. He also assists with wildlife rehabilitation and environmental education, including The Resources of Belize Coloring and Activity Book to be distributed to children in Belize . Alvarez is one of those individuals whose wide-ranging enthusiasm on behalf of wildlife and the environment influences others to care about the natural world around them.

Alright, an award ceremony, a Worth A Dam meeting with brilliant new minds, aren’t you doing anything else this weekend, you lazy beaver advocates? How about a display at the Trail Adventure to benefit Save Mt. Diablo at Castle Rock park in Walnut Creek? Well, okay. We’ll be at the expo from 9-12 where you can learn all about the various advocacy groups in the Bay Area.

The Save Mount Diablo Trail Adventure presented by Chevron offers a Half-Marathon, 10K Run, and Family Hike beginning at Castle Rock Park in Walnut Creek, climbing the fire roads up the slopes of Mount Diablo and finishing at Castle Rock. The event includes post race entertainment by a live band, expo and lunch for all participants.

Save Mt. Diablo is the big leagues in non-profit baseball. It takes big money to save a mountain, especially when you are saving it from being sold for even bigger money. They invited us after seeing how enormously popular our site was at the Flyway Fiesta event. We will be there to talk beavers, make friends and find out some excellent ideas for next years beaver festival! Stop by and say hi!


Daylight savings is kind to beaver watchers. You can stagger out of bed at 6 and get to the dam just in time for a streaky orange sunrise. This morning gave sight of Dad at the old lodge, one yearling at the annex, another at the frat house, and a third by the footbridge. A pretty good viewing.

Yesterday I met with the director of public works to discuss our children’s art tile bridge project. City staff were there as well. They had been excited about the project back when I presented to the Parks Marina and Cultural Commission in October. Their enthusiasm for the artwork and the tiles was fairly evident and they all wanted to make their own. It was a very friendly and productive meeting, and I kept thinking I had stumbled into the wrong room by mistake. It felt like one of those weird family events, where your stepfather had never liked you, and always told everyone you were a trouble maker and would never amount to anything, but then showed up at your cum laude graduation, saying he said he couldn’t be prouder and bought you a car.

Well, maybe not a car, more like a certificate for Jiffy Lube? Or one of those Shell Gas cards. Not extravagant, but still, not what you expected.  The most delightful part of the meeting was when I was asked to take staff on a beaver viewing some morning to describe the habitat and show off the dams. That doesn’t happen every day.

The beaver stone that was rejected has become the corner stone?

Anyway, Worth A Dam is officially on the agenda to present the full project to the City Council on November 18th. I have been told this is because the city wants to be included in this project and feel participatory. Beaver failure is an orphan, but beaver success has many parents. Come and support our beavers that night if you can?

So you remember how my marketing advice to Mike Callahan of Beaver Solutions included the need to identify some public beaver drama and walk onto the stage with a big shirt that said “hero” on the front? (Or if you’re Skip, no shirt at all?) Well I found his action yesterday, and it has all the pathos of a greek tragedy. Ripped from the headlines of an economy in turmoil, it includes the urgency of a leaky fawcett, the humanity of country club, and the environmental awareness of a cell tower.

With Massachusetts burdensome unemployment rate of 9.3, important victims of the economy are often overlooked. As restaurants and book stores close up shop, consider the poverty we can’t see. Consider golf.

The Ledges is an 18 hole golf course in South Hadley. It boasts “Numerous holes winding through protected wetlands and rock ledge outcroppings.” It opened as a plush expensive course, but wasn’t selling enough tee time and was then taken over by the city which manages this municipal course and allows visitors to pay 36 for 18 holes on a weekend. Seems it has some beaver problems and they considered installing a beaver deceiver to fix it, but course superintendent now says that they don’t have enough money to pay for those new fangled things and they had better just kill them after all.

The good news is that since its a city managed club, with protected wetlands, the conservation commission will have to weigh in. There will be a public hearing next week November 9th at 8:30pm. Seems like the perfect place for a heroic beaver management expert to show up, offer his services and prominently flout his upcoming DVD.

Just sayin’.
