As part of CDFW’s Beaver Restoration Program, beavers are back at work on the Tule River Indian Reservation. The beavers released on the Tule River watershed are expected to build dams that slow the flow of water and in turn create drought and wildfire resilience.

I remember during the 2012-2017 drought, the only stream we saw flowing around Lake Tahoe was downstream of a beaver dam. They're so important- very happy to see this happening in conjunction with tribal leaders and hope to see more in the future!

@Mosesphotoworx We need these ecosystem engineers everywhere they can thrive. I'm so glad we now have our own native European beavers again in the UK.

Beavers forever. We need more Beavers.

Wolves transporting the remains of beavers they have killed. Beavers are critical prey for wolves in the Greater Voyageurs Ecosystem for a 7-8 month period of time, roughly April to October/November…i.e., when ice on lakes and ponds is largely absent. Beavers constitute, on average, ~30-40% of all biomass wolves obtain from predation during this period. However, we have studied numerous wolves for which beavers are the primary prey during the spring to fall. For instance, beavers can constitute up to 82% of all biomass killed by some wolves during this 7-8 month stretch. In other words, some wolves rely almost exclusively on beavers during spring to fall and then deer almost exclusively during winter. Given how often wolves are killing beavers, we naturally get footage of wolves carrying remains of beavers they have killed, often taking the carcasses back to their pups. The reason wolves rely heavily on beavers is almost certainly due to the abundance of beavers in the area. Beaver densities have remained roughly around 1 beaver lodge per square kilometer (and there are ~5ish beavers per lodge) for about 40 years now. That is a very high beaver density, and likely is similar to, if not higher than, beaver densities in other southern boreal forest ecosystems in places like Ontario, Manitoba, and Quebec. We suspect beavers are, in part, why the Greater Voyageurs Ecosystems has sustained very high wolf densities for many years, and we are actively trying to understand how beavers drive aspects of wolf population dynamics. Prior to our work, wolf-beaver interactions had received very little attention or research. In 2018, we wrote a peer-reviewed publication summarizing all that was known on wolf-beaver interactions up to that point. In that paper, we dubbed beavers “the forgotten prey of an iconic predator." Of course, biologists knew wolves in a variety of ecosystems hunted beavers to an extent but that was about it. Fortunately, we have made substantial headway in understanding this predator-prey dynamic but there is much we still don't understand...which means there is still much to be discovered!

Absolutely incredible trail camera capture of a coyote attacking a beaver in Connecticut. You might be wondering: “You study wolves in Minnesota, why are you posting this video from Connecticut?” The reason is because this footage illustrates why beavers are important prey for wolves in many forested areas but not coyotes…even though coyotes inhabit many areas with quite a few beavers. Why is that? The coyote tries for several minutes to kill this beaver but the beaver ultimately escapes. Unfortunately, the video was not captured on video but the beaver with his bloodied tail is on the trail only an hour after being attacked. Ultimately, this beaver is almost as large as the coyote and the coyote struggles to really move the beaver at will because of the beaver's size and strength. The coyote bites the beaver's tail repeatedly but virtually never lands a blow to the beaver's muscular body. Coyotes, unlike wolves, simply do not have the strength and size to routinely kill beavers, especially large adult beavers. Wolves, on the other hand, not only have the strength to yank beavers around but they also have the bite strength to grab the beavers body and deliver crushing blows. Killing beavers is harder than it seems because beavers have no obvious neck or easy place for a predator to latch one. They are just one large furry football-shaped hunk of muscle, which complicate the logistics of killing them with one’s mouth, especially for smaller predators like coyotes. Of course, coyotes and other small predators do occasionally kill beavers, especially smaller beavers, but it is not a common occurrence, and there is little evidence that beavers constitute a large portion of coyote diets. We want to extend our sincere thanks to the Traprock Ridge Land Conservancy in Connecticut for reaching out to us and sharing this incredible footage they captured. And big thanks to them for letting us share the footage with everyone here. Capturing an encounter like this on video is one in a million!

The absolute trail camera jackpot—we just captured the second known video ever, as far we are aware, of a wolf attacking and killing a beaver. And this was a pretty sizable beaver too! How amazing is that!? Earlier this year, we posted rare footage we captured of a wolf in our area almost catching a beaver on a dam. That was really neat to see but in that video, the wolf never made contact with the beaver and the beaver narrowly escaped. This beaver wasn’t so lucky. In this video from Sept 17, the beaver left the water at 1:09 A.M. to go forage on a 49 m/160 ft long trail—a pretty long trail for a beaver. Just four minutes later, the beaver was attacked by Wolf V094, the breeding male of the Half-Moon Pack. A brief chaotic struggle ensued and then all went quiet as the wolf and beaver moved out of frame. About 19 hr later, we captured a video of a different wolf walking in front of the camera with a beaver head in its mouth. A few days later, we hiked out and found the bloody remains of this kill not far from our camera. The beaver put up a valiant fight and at a few points was only a few meters from the safety of water. If the beaver could have just freed itself for a few moments, it might have lived. But it couldn’t…there appears to be a thin margin for beavers between life and death when on land! The only other video observation we know of was recorded in Quebec in Fall 2015. Given how rare that was, we worked with the person who recorded the video and wrote a scientific paper on the observation trying to glean as much insight as we could from it. Bit of backstory on the video: The footage was captured by Dani Freund, a graduate student at the University of Minnesota, and two field technicians—Sage Patchett and Olivia Jensen—that are assisting Dani with her work. Dani’s graduate work is looking at how wolf predation and other factors influence beavers stress levels. In other words, do beavers in ponds with higher wolf activity levels have higher stress levels than beavers in ponds that have lower wolf activity levels? Or are beaver stress levels driven largely by other factors such as food availability or competition from neighboring beavers? The way Dani is examining beaver stress is by collecting beaver hair samples and measuring stress levels in the hair. And her hair collection method entails using a strand of barbed wire that the beavers crawl over to get on land (you can see this in the video). When the beavers crawl over the wire, tufts of hair get caught on the wire and then those hair samples can be collected and analyzed. This is a common method used to get hair samples —biologists often refer to barbed wire and other similar contraptions devised to collect hair from wildlife as “hair snares”. All this to say, this camera, which was kindly lent to us from the Offal Wildlife Watching Project at the University of Minnesota, was not set here in the hopes of capturing a wolf killing a beaver but rather to monitor beavers crawling over the hair snare. But sometimes it is better to be lucky than good! And we certainly think we had a stroke of luck. We have had a lot of cameras out over the past 9 years in the area and we have never captured anything like this!
