News from the Wolverine Tracking Project and more
Summer is cruising along! We hope you are getting out there, picking some berries, counting stars, and enjoying the season to the fullest. Volunteers on our camera and scat teams are getting out there and bringing back invaluable footage and genetic samples of our forest wildlife. Thank you to everyone who has contributed!
If you're looking for another excuse to get out to the woods, look no further! We'll be at Bark's Summer Base Camp to lead a Tracking Workshop on Sunday, September 1st - come for the day, a few nights, or the full two weeks of camping, workshops, and forest and beaver habitat surveys! Family friendly and FREE. We hope to see you there.
Keep the Sierra Nevada red fox scat survey in mind as you head out to the mountain trails this summer!
We're creating quite the stockpile of promising Sierra Nevada red fox scat, as well! Not every survey will collect scat, though, and that is as valuable as genetic information - lack of evidence of their presence is data that reinforces the rarity of this animal - and knowing what areas they are using is as helpful as knowing what areas they are not. Once we have enough samples, we send the samples for analyses to our partner at Cascades Carnivore Project (who is also researching the Cascade red fox, a cousin in the alpine areas north of the Columbia River). Depending on the quantity we collect, the whole process can take a year. The more we collect, the more timely we can get the data analyzed and communicated to researchers and management - and the better data set we will have.
Wolf survey: We also recently sent off five wolf scat samples to be analyzed by ODFW, and are looking forward to the news! A recent survey also found two new scat samples.
Depending on habitat connectivity, availability of prey, and other dynamics, a wolf pack can have a hunting territory of 50-1000 miles (larger territories commonly found in arctic and subarctic areas). While we know the White River pack is nearby, we are still learning about their territory, and a wolf from that pack or another could decide to venture out and claim new territory at any time. It's a good idea to keep an eye out for their signs, especially on the eastern side of the mountain - we never know where they may end up!
We've now seen footage from all our sites, and have a lot of photos for you, including some firsts of the season - and a first ever for this survey! As usual, we saw a lot of elk, deer, coyote, black bear, a couple mountain lions, and a couple bobcats. We of course saw a lot of Douglas squirrel, a lot of very busy chipmunks, at least one ground squirrel, and a few handfuls of unidentifiable rodents, but the star rodent this time was the largest member of the family Sciuridae, the yellow-bellied marmot!
This is the first time we have caught one of these giant ground squirrels at our cameras! They tend to live on and build deep burrows in talus slopes or alpine meadows, and, though it's not unheard of, it's a wonder that we would find one in this area, which is high-subalpine. Perhaps this one has recently been displaced or has chosen this sub-alpine forest for its abundant edible mosses, grasses, and wildflowers - favorite snacks of marmots.
These dapper rock chucks are named for their coloring, however, they turn tail and burrow at the slightest onset of cold. One of the longest hibernators in our region, marmots can begin hibernation as early as the end of July/mid August, but usually take the dog days of summer to continue building their winter stores.
The biggest present danger to this marmot is coyotes, but wolverines would also be a formidable foe if they reclaim their historic range.
Speaking of Mustelidae (the weasel family, of which wolverines are a part), we also caught sight of the first weasel of the summer!
This lithe and well-camouflaged animal has a unique, identifiable characteristic that sets it apart from other mammals of its size: a long, black-tipped tail which appropriately lends to its name of 'long-tailed weasel.' We always enjoy finding this voracious rodent-hunter on our cameras.
We also saw our first sooty grouse of the season at the same site (lower left corner).
Like other ground birds, a grouse is always a good sign for our forest carnivores like this bobcat, seemingly hot on its trail.
This other bobcat was very interested in the bait belt itself - but not the bait. Perhaps it was more interested in our human-scent from the camera setup than the canine-scent bait under the log; indeed, one of these two may present more danger than the other.
A fellow feline who rightly fears no animal, hominids included, this mountain lion took a moment of repose at our bait log...
...while another mountain lion was caught on the prowl.
We saw many black bear, like this one with its black and cinnamon coloration.
This bear visited a few times, and it really enjoyed using the camera tree as a scratching post, leaving us with quite a few pictures of the back of its head.
Two cubs of the year were caught at another site, though rarely on-camera at the same time. The mother, though (top background), was never far behind.
You can almost see the grin on this content coyote. This behavior could be fulfilling a purpose as simple as a good back-scratch. Or, considering the presence of deer in the area some nights prior, could be a way for the coyote to cover itself in the scent of its prey.
Meanwhile, another one of our cameras captured this very lucky coyote!
While the coyotes have seemed to move on from this site, for now at least, we did see a lot more hare:
More good news for our forest carnivores, a lot of members of the family Cervidae! Specifically, deer and elk.
The photos of this buck displays its summer velvet wonderfully. The antlers of a mature, well-fed and healthy buck can grow up to 1/4 of an inch a day. For bull elk, antlers can grow almost an inch a day. When velvet is present, the antlers are soft and susceptible to damage, and this is part of the reason why bulls and bucks will tend to stick to a smaller territory, with other males. The velvet sheds when the bone begins to set, about mid- to late-September, just in time for them to roam.
We didn't see too many bull elk this time, but we did see quite a few herds of cows and calves.
We also saw two elk that were tagged and collared...
And were treated to some beautiful photographs of a very curious elk! Hello!
We have one more first of the season to share with you, the raccoon:
If you live in a city, chances are you've seen one of these recently. Though more common to see in urban areas, they are still woodland creatures. Like coyotes and other fauna that easily transition to urban areas, they are highly adaptable to their environment. Their presence as scavengers and hunters is always a good sign, and it's always encouraging to see diversity in the forest.
Thanks for reading. We'll be back with more updates soon!
