Happy Halloween and happy news from Colorado where the Historical Society just installed a flow device for the very first time!
In the Gunnison Valley, you’d be hard pressed to find a rancher who doesn’t view beavers as a major inconvenience. Apart from flooding roads and other areas, beavers can damage trees and clog up culverts.
“I can’t overstate how many people have this problem,” explained Western Colorado University Master in Environmental Management student Malcolm Macleod.
The Aberdeen Quarry, located southwest of Gunnison, marks the latest subject site of busy beavers’ devastation, leaving the main route to the quarry below about three feet of water this past summer.
A massive dam — stretching nearly 100 feet long — was the culprit of continued flooding in the area, leading the Gunnison County Pioneer and Historical Society to cancel their annual tours of the historic area distinguished by large granite deposits used to construct the Colorado State Capitol building in Denver in the early 1890s.
However, rather than eliminate beavers from the area altogether as has been tradition elsewhere in the valley, the Historical Society searched for an alternative solution.
“South Beaver Creek is named Beaver Creek for a reason,” laughed Barry. “Beavers, depending on who you talk to, can be very beneficial or they can be a big problem.”
Or you know, they can be BOTH. Good things are worth fighting for. I heard that once.
That’s where Western’s Macleod came in. The now selfproclaimed “beaver believer” proposed a new way of humans co-existing with the creature.
Under a fellowship with the Coldharbour Institute, Macleod worked to develop and implement water management strategies to holistically benefit the land. It was when he stumbled upon a beaver carcass during his research that he considered the real impacts of the largest rodent in North America.
“I quickly realized everyone saw the beaver as a pest,” explained Macleod.
If there’s a beaver dam located on the property, the course of action often means removing the dam and killing the beaver, said Macleod.
However, Macleod has come across a different way of doing things — in the creation of what’s known as a “beaver deceiver.” The deceiver is essentially a flow-control device in the form of a flexible pond leveler.
This is a type of device places a pipe through the dam, allowing humans to control the water level. The pipe is protected from damming on the upstream end by a steel wire cage.
The device’s purpose is twofold — it works to prevent flood damage while at the same protecting beavers that have made a home there.
First rule of business. Don’t call it a HUMANE device. That label won’t keep the neighbors happy. Call it a STRATEGIC device. It solves the problem and allows that beaver to stick around and serve the community by saving water, preventing erosion, removing nitrogen and increasing biodiversity. Then they can stick around and prevent more beavers from moving in. Let the beaver do the work, as they say.
As it turns out, there are entire institutions dedicated to addressing the huge need for trained professionals to better manage beaver conflicts. Macleod is currently earning his Beaver Professional Certification to be better equipped at helping local stakeholders manage beavers in a mutually beneficial way.
Hurray! the first graduate of The Beaver Institute’s Professional Program! I feel just like a proud grandma!
According to Macleod, the most common beaver problem plaguing the Gunnison Valley comes from dammed culverts.
Despite the beaver’s bad rap, the benefits of keeping them around may also aid ranchers in the long run, he said. Not only does the continuous battle to remove the animal come at an economic cost, but streams may suffer too.
“Streams like to be messy,” said Macleod.
That is, each beaver dam acts like a speed-bump — slowing down the flow. This, in turn, adds to the biodiversity and overall health of the waterways.
“What people don’t realize is that beavers are farmers too,” explained Macleod.
For ranchers grazing cattle, beaver activity is part of an ecosystem chain that aids the production of lush, high-nutrient forage in riparian areas, providing another benefit. Beaver dams also help store water during dry years.
“Hopefully it works so that beavers can co-exist in the ponds as we take people out on tours down the road to get to the quarry,” added the Historical Society’s Barry.
Wonderful! Congratulations Macleod! We in Martinez are rooting for you, and know that success is possible. I’m sorry the water was icy when you jumped in and hope your wetsuit was warm enough to let you finish every step you needed to complete! It’s wonderful to have another flow device installer on team beaver!
Finally there is word from Safari West after 48+ hours and a whole lot of fire. All our hearts go out to them and their employees whose homes were lost to fire. Again.
For the second time in as many years, our beloved north bay community has been touched by wildfire. Our hearts break for friends and neighbors who have been forced from their homes. I want to convey our utmost gratitude for the dedicated firefighters and first responders who’ve worked so hard to defend and protect Sonoma County.
Safari West is doing remarkably well at this time. On Monday night, the fire moved our direction. It crossed the boundary fence on the northeast edge of our property but our on-site teams, aided by Cal Fire, were able to stop its advance. Since then Safari West has remained largely free of impact from the fire and to date our entire collection and staff are safe, secure, and healthy.
With the windstorms mostly over, it would be too easy to think we’re now in the clear. The unfortunate reality however is that wildfires are not so easily discounted. Safari West is doing incredibly well at this time and we plan to reopen as soon as possible but I want to emphasize that we will remain closed and evacuated until the fire is fully contained, evacuation orders are lifted, and Cal Fire gives the all clear. So many of you have reached out to us offering your love and offers of aid. The best thing you can do for us right now is to keep the roads and neighborhoods under evacuation clear and let the firefighters do their work. We are privileged to have so many supporters but right now, others in the region need your help more than we do.
I hope you’re all staying safe and healthy. We’ve been through this before and demonstrated our amazing ability to come together as a community. We will do so again. We’re still in the midst of an evolving situation but no matter what the next few weeks brings, we’ll get through it together.
Sincerely,
Keo Hornbostel
Executive Director
Under a permit from Colorado Parks and Wildlife, Wildlife Services-Colorado used suitcase traps to capture five beaver causing damage elsewhere. They were trapped during the summer months until mid-September in order to relocate them when they were old enough to survive on their own and find adequate habitat before winter.
