The bright sparks of dimly lit Nevada are continuing to process ground-breaking research and expert advice using their intricate circular filing method. They have received consultation from the Sierra Wildlife Coalition, the Human Society, the Sierra Club, Occidental Arts and Ecology Center, and Worth A Dam, so of course they are paying the most careful attention.
Sparks changes tactics with nuisance beavers
Nuisance beavers have been gnawing their way through trees and building dams along the North Truckee Drain in Sparks, causing damage and increasing the risk of residential flooding.
After spending city resources focusing on the dams to little long-term effect, the city of Sparks recently tried to shift its focus to the beaver population itself. In order to mitigate the problems caused by the dam-building beavers, the city was advised by the Nevada Department of Wildlife to seek a special permit last month to catch and kill the animals. As of last week, however, the city decided to put that strategy on hold, concerned about the inhumane nature of the process.
The permit, which was issued Nov. 10 and is good for a full year, gave the city permission to remove the animals through trapping and/or shooting them, which they decided to do through a third party contractor. Captured animals are not allowed to be moved or relocated due to the potential spread of disease, such as the infectious bacterial illness tularemia, and the territoriality that occurs between beaver populations.
The beavers in Sparks were being trapped underwater to avoid potentially capturing domestic animals, or even small children, above ground. The beavers were drowning to death, which the city now feels is not the most humane way to take care of the problem. Five beavers were killed in total.
Well at least they finally got the beaver deaths reported, even if they didn’t admit that it was an entire family. Sherry and Ted Guzzi have been hard at work offering solutions to problems at hand, and we had a long discussion about how to wriggle maximum support out of their lying, opportunistic mouths. But obviously there has been little real change. Just look at what Mr. Healy is saying even after I specifically sent him three research articles on beavers and birds.
“This is part of the ongoing drought,” said Chris Healy, spokesman for NDOW. “When we have troubles with drought, water sources are limited, and so instead of the beavers taking out willows and creating dams, they go up drains and start taking out trees.”
Nevada law allows for the aggressive removal of beavers that are obstructing the free flow of water. Beavers can also cause significant damage to a river’s ecosystem, Healy said, in that they remove the limited number of trees that provide nesting for local birds and contribute to healthy fish habitats.
“Trees take decades to grow, whereas beavers only take a season to grow,” Healy said. “Nobody wants to kill an animal, but in some circumstances we have to do that. There are logical reasons for why we do what we do.”
Apparently trees in Nevada don’t coppice and Mr. Healy has never heard of the work beavers are doing to restore streams just up the road in his very own state. His is also unaware that beavers don’t respond to drought by moving into city drains. He feels no need to trouble himself with the research saying that beavers help birds, because he obviously knows better. Five years ago I’m sure he’d be saying beavers don’t belong because they’re not native. So that progress of a kind. And hey, beavers DO take less time to grow than trees. He’s got me there.
I guess what this all proves is that you can lead the NDOW to information about water, but you can’t make them THINK.
We need a good story to get that taste out of our mouths. This will do nicely.
New Beaver Dam in Roosevelt Forest teaches Lauralton Hall & Fairfield Prep students about beaver ecology
On November 24, Lauralton Hall students and Fairfield prep students met up with Christina Batoh, Stratford’s Conservation Officer, to learn about beaver ecology at the site of a recently constructed beaver dam in Roosevelt Forest. Students set out to answer the question, “Does the presence of the beaver dam impact stream water quality?” To do this they tested water samples from an upstream site.
Lauralton Hall students instructed their Fairfield Prep counterparts in how to conduct tests for dissolved oxygen, carbon dioxide, turbidity (sediment load), and pH. Students then analyzed their test results and concluded that the presence of the beaver dam does indeed impact stream water quality with water downstream having better quality than the water upstream or at the dam site.
Got that? Did the high school student go to fast for you Mr. Healy? Let me know and I can slow them down. There’s more to talk about in the Ecologist this morning, but I have a conference call for the paper this morning, and am going to have to stop for now. For some reason, I’m thinking this video might be helpful to our new BFF in his scientific quest for the ecologic advancement.
