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

Day: July 27, 2022


If you’re lucky in this world people report on your scholarly achievement when it’s newly published. People like shiny new things. You can show the article to your mom or dad and they will feel as if their college dollars were well spent. It helps you get hired so you can support your own research next time. That’s what happens if you’re LUCKY.

You would be crazy to expect them to be talking about this research 5 years later. Even 2 years later is pretty unlikely. But not if you’re Jeff Baldwin.

Beaver Politics in Oregon

A North American Beaver – Castor Canadensis – sitting in the grass grooming itself. Along the shore of a wetland pond. Near Portland in Western Oregon.

With climate change transforming the American West, an industrious mammal could help mitigate some of the worst of the coming drought and flooding crises. The West is getting drier in the dry season and more prone to flooding in the wet season. Beavers could well be a relatively low-cost part of resiliency efforts. As natural ecosystem engineers, these largest-of-North-America’s rodents “increase water storage in ponds and surrounding floodplains, thus slowing winter flows, increasing riparian and meadow water availability, and extending stream flow up to six weeks into dry summer seasons.”

But in Oregon, the Beaver State, beaver politics, for want of a better term, make reintroduction problematic. Scholar Jeff Baldwin details the institutional obstacles to the use beaver in mitigation initiatives. Public policy is mostly controlled by those opposed to the animals. Across seventy-five percent of the state, a predator designation means they “may be killed without record or regulation.” The same statute also guarantees that no information is collected about these killings. Evidence of beaver extirpation is therefore anecdotal and “dismissed as such.”

For more than a century, “state and federal governments have vacillated between promoting and killing beaver.” For instance, Oregon banned trapping in 1899; rescinded the ban in 1918; re-instituted the ban in 1932; then allowed trapping on agricultural land in 1951. There aren’t very many licensed trappers today, but they have a strong lobby. And with the predator listing, you don’t need even a license to kill them in plenty of places.

Well that is crazy I agree. But to be honest things are no crazier in Oregon than they are in California. Probably a little LESS crazy to be honest. We are all suffering from no water or too much water and we’re both highly flammable. We both should be standing in line waiting for our turn to have beavers on our land.

But of course we’re not.

Meanwhile, reintroduction efforts, in cooperation with landowners, in the 1940s successfully boosted beaver populations, a history forgotten by the Oregon Department of Fish and Wildlife professionals Baldwin interviewed.

Before all this, beaver populations across North America were attacked with gusto to feed a European market that had already trapped out Europe’s indigenous beaver species. Estimates of the pre-colonization population of beavers in North America run from sixty to three-hundred million. Today, the population is estimated at three to six million, mostly in Canada and Alaska.

Journals of explorers and trappers testify to Western landscapes built in part by beavers. Writes Baldwin, “Now-channelized and arid valley floors across the American West were once difficult to traverse due to multiple channels and broad riparian flood plains covered by dense vegetation.” Could such landscapes, created and maintained by beavers, be brought back?

Gee I don’t know. Something seems to be standing in our way. Something pesky and wide spread. What could it be? I can’t quite put my finger on it.

Examining “the culture of land and wildlife management professionals and policy makers,” Baldwin conducted forty key informant interviews and did a “critical review of literature published by state wildlife management and climate change institutions.”

He found five institutional obstacles to beaver recolonization and/or reintroduction. Two were legislative. Beavers are listed as predators—pests of agriculture crops and products—so they can be killed with impunity. And climate change policy recommendations have to be “politically neutral,” meaning they are essentially impossible to enact, as neither beaver nor climate change is considered apolitical by many of the involved bureaus and land managers.

The three other obstacles were “positions shared by many wildlife management specialists.” These were: there are enough beavers already; licensed trapping doesn’t affect population; and reintroductions are ineffective. Baldwin’s research undermines all three of these assertions.

Alright JEFF! Tell us why!

In fact, “the benefits of beaver recolonization,” are well-established and well-documented, but Oregon’s political process stymies action. Between 2008 and 2017, nine state agencies and working groups released thirteen reports addressing climate change and wildlife and land adaptation. Baldwin notes that none of these mentioned beavers. To avoid controversy and legislative veto, the reports “generally avoid calls to make any material changes.” [Baldwin’s italics]

In Oregon, the Department of Agriculture “also represents the timber industry,” and since beaver reintroductions can lead to “road failure,” the powerful industry demands the right to control beavers on their land.

Politics and attitudes don’t change as fast as the climate. The fate of the giant Castoroides beavers, as large as bears, may be a teachable moment here: climate change did them in.

Baldwin concludes that de-listing of beavers as predators would be a key step to re-beavering the Beaver State. Meanwhile, Oregon’s indigenous tribes are already paving the way with beaver reintroductions of their own

Well they say all politics is local. I would say that “All politics is beavers”. Beaver is the ultimate NIMBY. Try living with a beaver dam in your city for a decade and you’ll know what I’m talking about.

The article ends with a nice reference to Jeff’s paper and a link so readers can see for themselves. Remember that Jeff is at Sonoma state now and was the one responsible for getting the beaver  summit to be hosted there. He was thrilled when I sent him this news article. You can see why.

Maybe if we drown the west in good news about beavers SOMEONE will finally start paying attention.
