CEQA, FPCP, GPR: SOS!!!

Ahhh the new baby always brings out the best in family and friends. Today this photo ran in the San Francisco Chronicle with a very glowing article by longtime beaver-beat reporter Carolyn Jones. The article has an “alls well that ends well” feeling, and quotes from Skip Lisle and Dave Scola as well. I, of course, wish she had mentioned Worth A Dam or the beaver festival in the article (an article entirely structured around my press release and our half hour interview, including the latin for beaver!) but at least she got the story straight and the details of our very special family in print for all to see. And, most important, it was the first beaver article in history without a single “pun” in the title to indicate that this wasn’t “important news” and the story shouldn’t be taken seriously. You can help us out by “voting” for my comment so that the important things Carolyn forgot to mention get mentioned!

As if that wasn’t enough good news for one morning, my post yesterday about the contest in Lithuania prompted this heroic response from Alex Hiller, our foreign correspondent in Frankfurt Germany.

Thank you for your information about Riga beavers at risk. As a participant of the 5th International Beaver Symposium in Vilnius, Lithuania, the previous year I decided instantly to go to Riga, Latvia, checking on the beaver site and considering proper solutions to keep the beavers. I just got a Lufthansa flight ticket to Riga, Latvia, departing in Frankfurt, Germany on July 21 for a week to be spent over there. Expect online reports and photos as your approved foreign correspondent.

Skip Lisle & Alex Hiller at 5th annual Beaver Symposium in Lithuania

Alex tells me that he’s already hard at work, translating articles and looking up photos. I can’t tell you how pleased and proud we are of your committment Alex! On behalf of the beavers of baltic countries everywhere, THANK YOU!!!

One more act of kindness worth mentioning comes from our good web designer friend Jean Matuska of JM Design. I was beginning to receive ominous error messages when I posted new articles on the website, something dire about a “Fatal error” which terrified me. Jean went searching through her tool kit and figured out the solution, redesigning our memory limits and voila! No more fatalities! Thanks so much Jean! We will leave a smaller data footprint in the future!

Swept it for half a year.

“That they could get it clear?”
“I doubt it,” said the Carpenter,
And shed a bitter tear.

Skip Lisle & Alex Hiller at 2009 Beaver Conference in Lithuania

Hi Heidi,

you are receiving the summary of the first lecture day – September 21, 2009, – at the 5th international Beaver Symposium. I had to solve unexpected difficulties in getting Internet access. Proudly wearing your “Worth a dam” T-Shirts Skip Lisle immediately recognized his adventures in Martinez , CA, when getting sight of me just after breakfast. Another participant from Denmark pointed at my T-Shirt telling me that he knows about it via Internet

Skip is well known to the citizens of Martinez, CA, for the construction of a “castor master” beaver dam flow device in Alhambra Creek one and a half year ago. His talk at the end of the second lecture day was the most practical and instantly useful of the whole conference. If anybody wondered what could be done about flooding problems regarding co-existence with beavers, Skip would have the proper solution at hand.

From the presentation of Peter Busher: Darwin and the elephants

“Beavers, in a population sense, can be regarded as `mini elephants`, since they are also relatively large (for rodents), long lived and have few predators (other than humans) in most natural situations.”

Prof. Peter Busher from Boston University, Massachusetts, as chairman of the scientific committee referred to Charles Darwin who developed 250 years ago on the population dynamics of elephants his evolution theory. DarwinŽs famous book “The Origin of Species by Means of Natural Selection or the Preservation of Favored Races in the Struggle for Life”was published in 1859. Moreover in 2009 it is the bicentennial of Darwin (1809 – 2009 ).

According to Busher Darwin had developed an exponential growth equation, that given one elephant cow starts calving at the age of 30 for the consecutive 60 years until death meanwhile giving birth to a calf every three years that reaches maturity itself following the same scheme we should expect 19 million elephants to live on earth within a surprisingly short period of time. In fact we know that such kind of equations cannot come true according to loss of habitat, hunting, disease, accident, wildfire, extended drought etc..

Busher insisted on long-term investigations “since any short-term study does not allow
a full understanding of the natural pattern of change in beaver populations: The general long-term pattern is one of slow initial growth, exponential growth (traditional “J” shaped curve ), decline and stabilization around a carrying capacity”.

For example the number of beaver sites in Voyagers National Park, Minnesota, increased from 50 to 360 between 1940 to 1985 whereas the number of beaver individuals throughout the entire state of Massachusetts increased from 22500 to 65000 within 8 years from 1994 to 2002 according to Busher. What was rich growth, what was poor
growth ?

Change in population size occurs regardless of the density, populations fluctuate over the time, finished Peter Busher his lecture that could be regarded as a proper measure for the numerous detailed presentations following on that topic.

Among the presentations were investigations on the reasons of population change, such as food competition among elk and beavers researched by Glynnis Hood, assistant professor at the University of Alberta, Canada:

Caused by overpopulation elk chewed down tree saplings knee high in Elk Island Park Alberta, Canada. On the contrary, according to Hood “beaver turn down a vertical forest into a horizontal” by felling trees in order to forage on leaves and twigs. It were the beavers smart enough to adapt their foraging behavior, given array of forage species, “which potentially buffers the effects of competition between elk, deer and beaver.”

Other topics of the first lecturer day were beaver biology and paleontology at the International Beaver Symposium being performed from Sept. 20 – 23, 2009, in the little eastern European country of Lithuania sited between Baltic Sea and Russian border. Mild temperatures and sunshine made it easy and comfortable to stayand socialize .

On the red pine shaded conference center at a marvelous lakeside in Dubingiai north of Lithuanian capital Vilnius 99 beaver enthusiasts of almost scientific background from all over Europe were joined by 6 leading North American beaver specialists, among them Peter Busher and Skip Lisle.

More to come!
