Fans of the Martinez Beavers will understand more intimately than most that the survival of our beavers ultimately depended on just one thing. Sure public outcry made a difference, and fear of political ruin quivered the hearts of at least two on the council, but if the dam had stayed at its original height and continued to pose a flooding threat, they would have been soundly dispatched. (Sent in a pickup truck to Plumas county if the god’s were kind or off to a glue factory somewhere if they were not.)
What fundamentally allowed the beavers to remain with us was the flow device, installed by Skip Lisle and often mistakenly called a “beaver deceiver”. (It’s actually a “Castor Master”.) This allowed for the water height to be lowered in such a way that the movement is disguised from the beavers. They don’t feel the suction and don’t associate the outflow with their dam, so they tolerate the water loss. Skip invented the beaver deceiver during his work with the Penobscot Nation. He went on to develop his ideas for the flow device and round fence over time. Skip is committed to showing the world that flow devices work. He traveled to Lithuania this summer to talk at the conference there, and he is headed for Oregon next week to give a four hour teaching at the State of the Beaver Conference.
Mike Callahan of Beaver Solutions trained with Skip and eventually developed his own full time business around beaver management. His vision of the best use of management skills included a teaching DVD that would allow property owners, cities and transit workers to cheaply implement tools that could manage problematic beaver behavior. He is well aware that allowing this keystone species to remain takes care of so many others, but Mike is a pragmatic beaver defender who helps businesses focus on the bottom line. Installing a successful flow device, he argues, can manage the problem now and in the future. Hiring a trapper is a temporary solution that will get more expensive over time.
Mike was awarded a grant from the AWI last year to make the DVD, and has been working towards its release. Expect it in the Spring of 2010. Recently he approached me asking to pay to include three minutes of my beaver footage in the production. Since Mike’s smart website was the first place I turned with beaver questions LO these many moons ago, and we became friends over the ensuing years, I can’t think of anything more “full circle” than using that footage to help him and help beavers around the country for years to come. Whatever financial agreement we figure out will go to Worth A Dam.
In the mean time, I am helping him spread the word about the upcoming project with an announcement postcard sent to beaver supporters and interested media. You might recognize my favorite photo from Bob Armstrong of the Mendenhall Glacier Beavers. (He gave his blessing on the prospect, and arranged for Mike to come do a beaver management plan in the state park there.) The idea is to follow up with a second announcement once the project is released. I’m hopeful that by helping more people learn that there are reasonable ways to manage beaver behavior, and inexpensive tools for learning about them, we can significantly impact the well-being of beavers all around the country.
In the mean time, our wikipedia friend is supposed to be honing a “flow device” entry this weekend. It’s hard to remember so long ago, but in 2007 I definitely had to hunt to find out about options. Remember how many people talked about the Clemson Pond Leveler at the meeting? Someone from Lafayette even donated the funds for one. That was one tool that had been published and talked about, but the technology had already come a long way since then. Mike was the one who explained that to me. Let’s hope “flow device” becomes a household name – at least as common as “snare”.
