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

Month: February 2009


Thinking your love should be true to you forever? Beavers agree. They take a single mate and stay faithful for the duration of their lives. Although after a mate dies they may seek another, they are not tempted nor do they wander during the 5-10 years they stay together. Beavers have such demanding lives (raising kits, building and maintaining dams) that they don’t have time to squander on recurrent courtship. They make a choice and stick with it, and they are understandably careful about that choice. Sharon Brown of Beavers Wetlands and Wildlife, writes that rejecting a “unsuitable” suitor is definately part of a beavers life experience. They pick carefully and then honor their decision with a lifetime of hard work.

Why am I telling you this with a large 75 in the corner?

You may have heard about it being the 75th anniversary of our East Bay Regional Parks. Think about that for a moment. In 1934 while Hitler was sending out the long knives and American was terrified about the great depression and the huddled masses were hoping the recently elected FDR could bring them out of it, public lands were being set aside for our use today. (It’s no secret that public land is often most easily purchased during a tanking economy, and all the wild creatures that depend on EBRP may thank you very much for your recession if the trend holds). Still, the ability to see down the road to a time when there would be few farms and wild spaces in Contra Costa, required real vision. What will Californians need 75 years from now? What will be in short supply, besides clean water and moderate temperatures?

So on Valentines Day, EBRP will be celebrating at the Martinez-Contra Costa Museum, (the one on Main Street, not Escobar) with our own ward 7 member of the Board of Directors, Ted Radke. Ted will say a few words, thank some friends and then lead a walk from the museum, through the beavers and down to Grangers Wharf. He invited myself and Igor Skaredoff to come along and talk beavers and watershed.

You can bet I’ll be mentioning monogamy.

Ted has high regard in my book, as he was one of the first “big names” to show support for the beavers. I read in an EBRP newsletter nearly two years ago that he had shown my beaver videos to the board, and quickly wrote him in appreciation. I got back a lovely handwritten card, thanking me for my work and saying that he and his wife, Kathy enjoyed visiting the beavers from time to time. I was so tickled the card went straight into the scrapbook. One farmer’s market Sunday he strolled by and flipped through the book appreciatively, and was startled to find his own handwriting.

(It had to go in the book, was all I could say. Honestly his support was the first indication I got that we might prevail.)

So if you’re around Saturday, and looking to encourage a little monogamy in your loved one, you might drop by. I think the walk will begin around three, and the presence of many beaver supporters can only a good thing. Remember that our two yearlings will soon become “Dispersers” and the odds of their ending up in EBRP lands are pretty high.

Always make nice with your potential landlords, is my motto.


Okay, so yesterday I explained about Ian Timothy’s science win of the 2008 Virtual Challenge at the Louisville Science Center with his  entry on beavers. Googling around for news about the contest report I found Ian also won second prize as part of National Health Week for an essay contest with his work entitled “What would life be like without clean water.”

I see a young environmentalist in the making.

As promised here is Part Two of Beaver Creek:

(Love the Stick’os)

Also heard from Ian that the Nelson Textbooks of Canada paid 350 to use Part One as a DVD for 3rd grade language arts textbooks. If I were Ian, I’d send a DVD of my beaver video to the River of Words Library of Congress contest.

Add a note saying, sometimes language is visual…..


Back in september we posted the claymation wonder from then 13 yr old Ian Timothy of Kentucky. He loves beavers and sent us his first beaver production. Ahhh, times change.  Now he’s 14, still loves beavers and decided to enter the “Virtual Science Contest” for his local museum and won FIRST PRIZE of a 1000.00 dollars with this beaver video.

Stop by youtube and give him 5 stars, for this truly remarkable entry. (That’s his Dad on the Banjo by the way.) I told him he’s an honorary Worth A Dam member, and his t-shirt was in the mail. Tomorrow I’ll put up his “Beaver Creek” Part II.


Our beaver friend from Ontario writes that there was such public outcry in St. Catherines that the whole extermination plan is being reconsidered,

 

Dear Heidi – we have made some headway in regards to the beaver trapping, here in St. Catharines.  NAfA had a meeting with The Parks and Recreation Dept. (the people that initiated the trapping), it went pretty well.  They’d like to meet with us again to further discuss things.  Right now they’re doing their own research.   The Ministry of Natural  Resources can offer them trees to plant and they have the contact info for the City of Hamilton who apparently also had a ‘beaver’ problem which was resolved peacefully. We said we’d like to work with them on this issue, perhaps by organizing a count, tree-wrapping, dropping of branches etc.

 

She wanted info and advice so she can come back to the table suitably armed. She sent a collection of letters published in the St Catherines Standard, and this one really stood out. I guess beavers really do change things….and people.

 

Hello Mr. Gill,

 

Let our family add our voices to the many who have been requesting the city revisit its decision to trap beavers along the Twelve Mile Creek waterway. We were horrified to read the city is doing this, especially when it appears there are alternative measures to be taken. When there were problems with Canada geese along the Welland Canal Parkways trail, did the city hire someone to just go out and shoot them? No, to its credit, the city was creative in its thinking and took preventative measures which were humane and progressive.

 

More and more our children are taught to respect nature. As urban dwellers, we have to co-exist with the wildlife that inhabits our shared greenspace. Beavers are in the Twelve Mile Creek watershed area because it is a good habitat for them. Surely simply killing the ones living there now will only mean more space for other beavers to take up residence there in the future.

 

Our family enjoyed a walk along the Twelve Mile Creek trail from Welland Vale up to Erion Rd. over the Christmas holidays. We were excited to see evidence of beaver activity in such an urban environment. Our children examined the tree shavings and marveled at the way a beaver systematically removes trees, most of which were small saplings. We looked for their dams and spent a lot of time talking about beavers during our walk. We even sought out books about them when we visited the library later that day. However, just a couple of weeks later we read the awful news in the paper about their fate and naturally, our children were very upset.

 

Please investigate the alternative, more humane measures of dealing with these beavers. Adopting the very “old school” attitude of dealing with wildlife (i.e., eliminating it) is, we think, failing to show progressive leadership on this issue.

 

Thank you, Mr. Gill, for hearing our views.

I was just looking up dates and realizing that this time last year we had flocks of scaup flying up over the dams to feed in Alhambra Creek. I think one morning Cheryl counted 30. I was assuming it was later in the year but this picture of mine was taken at the dam and dated February 14th (and don’t I have a romantic life!) Yesterday I did another scaup search. Where are they?

Scaup are an interesting, carnivorous duck that feed on mussels or clams and have the dubious distinction of being able to “play dead” if caught by a predator. We were never sure if they were Lesser or Greater Scaup, because the two species look very alike are are typically differentiated by the presence of absence of salt water. With Alhambra Creeks brackish tidal mixed drink it is anyone’s guess. Last years’ highwater (before the flow device was installed) and then the sudden lowering in January created a bigger mussel population, so maybe that’s why they came then and were less enticed this year. Or its possible the broad barren dredging project discouraged them.

Or maybe they just don’t like sheet pile.

Still, the increase in scaup last year was something of an estuary “coup” since the San Francisco Estuary Project’s State of the Estuary Report described declining scaup every where in the bay area, and didn’t realize the Martinez had gotten lucky!

Keep your eye out for our missing feathered friends, and write if you see anything swimming that looks like an oreo cookie.

UPDATE:

Reader CM writes “Saw one scaup swimming alone just north of starbucks on Monday”. Hear that team? Go find some others….Thanks CM!
