News from the Wolverine Tracking Project and more
Thank you for helping us exceed our fundraising goal!
The start of the new year also brings an end to our December fundraising campaign! We want to thank all of our members, and everyone who donated for making last months fundraising effort such a success! As a volunteer based, community centered non-profit, we are dependent on the support of all of you to keep Cascadia Wild running strong. Thank you for showing up for Cascadia Wild last month, and all year long! 2021 was another challenging year in many respects, and we remain forever grateful for this community and all that we are capable of together!
With your help, and the help of our generous board members and local businesses who donated, we raised $3,900. That accounts for over 10% of our annual budget! Your donations help us to keep teaching naturalist classes, hosting nature-based clubs, and running the Wolverine Tracking Project!
Brrrr, the PNW ended 2021 with chilling temperatures, icy roads and lots of snow! These conditions have kept our Wolverine Tracking Project volunteers on their toes, as they bundle up and head to the mountain to maintain cameras and survey tracking transects, facing all sorts of unexpected challenges along the way. After the massive amount of snow Mt.Hood has received in the past few weeks, snow shovels are a must for many camera sites, as volunteers have been digging out buried cameras and replacing them above the snow line. Tree branches (and even trees sometimes!) can be brought down by the weight of the snow, and sometimes end up obscuring camera views. Our capable volunteers have been moving cameras and removing branches to make sure that the WTP cameras don't miss a thing!
Lots of winter snow can certainly add some difficulty to volunteers jobs, but it also makes for excellent tracking conditions and beautiful scenery! The mountain is truly a majestic and awe-inspiring place to be this time of year, just look at this stunning picture taken by one of our volunteers on a camera check recently!
One of the coolest things about monitoring wildlife on Mount Hood is that you never know what you are going to find! We had some predictable detections on our cameras over the last month- our regular forest friends ( bobcats, coyotes, deer, squirrel, etc), as well as some mystery detections that we are still working on identifying! The same can be true for tracking- by now most of our volunteers are familiar with the sight of a Douglas squirrel track bounding through the snow, but some tracks can be tricky! It's all part of the fun!
Below are some of the highlights of our WTP findings over the last month! Keep scrolling to the bottom of this post if you want to see some of the photos that we have been puzzling over.
Camera And Tracking Surveys
One of the most intense wildlife interactions ever documented on our trail cameras was this scene capturing both a buck and a coyote running through the forest!
An intense scene unfolds in the forest!
The buck is seen running through the clearing, pausing and staring at the camera for a second, and then taking off again. This made us wonder if perhaps the sound or the flash of the camera startled the buck, and caused it to pause. A coyote charges through the scene right after the buck and then doubles back to sniff at the bait log at the camera site. Was the coyote chasing the buck? Were they both running from something that startled them? Was this just a strange coincidence? We can't know for sure but it sure is fun to speculate!
Below are more coyote detections from the past month! Coyotes are a common sight at our camera sites- we often capture footage of them sniffing around and marking near the bait box.
From top to bottom: A coyote strolls up to a bait box to give it a whiff-if you look closely you will see their companion in the top left corner; A excited coyote runs up to the bait box and circles it, showing us a little upward dog stretch in the process; A beautiful coyote sniffing around a frequently marked spot at a camera site.
Our next detection is extra exciting because its a first for this season! This elusive feline goes by many names- cougar, mountain lion, puma, panther, and a personal favorite: mountain screamer! Cougars are a rare sight, not because they aren't around, but because they are very shy.

The other feline found in our region are cougars slightly smaller relative- bobcats! We capture bobcats pretty frequently on our trail cameras, and their tracks can be a common sight in the snow at some of our camera locations!
From the top: A bobcat crosses over a log; a bobcat strolls through a camera site; two bobcats traveling together are seen walking towards the camera.
There were not very many black bear sightings this month, which is no surprise since many of the bears at higher elevations will have settled into their dens by now. We expect to continue to see some black bear activity throughout the winter, particularly at lower elevation camera sites.

Carnivores come in all shapes and sizes! One of the smaller carnivores in our region is the weasel. There are both short-tailed and long-tailed weasels in Oregon. These species can be hard to distinguish, typically long-tailed weasels are the bigger of the two, however both species are sexually dimorphic, so there is some overlap in size of a small female long-tailed weasel and a large male short-tailed weasel. Both species turn white in the winter!

Deer are another common species detected on our wildlife cameras. Deer social groupings can shift throughout the seasons, although females are usually found traveling with their young year-round. They may travel with other females and juveniles to form small herds. Males are often solitary through the winter but may travel together in small bachelor herds in the spring and summer.
From the top: a deer crosses through a dusting of snow; two male deer are detected traveling together; a deer walks through the snow.
In the second photo two male deer were spotted traveling together! While it may be less common for two male deer to pair up in the winter, it's clearly not out of the question!

Now on to some of our smaller forest friends. Below you can just make out a snowshoe hare bounding through the snow- look for the flash of their eyes on the right hand side. More visible are the tracks left behind! Snowshoe hare tracks in the snow often leave a distinct trail pattern that resembles a T.
From the top: A rabbit seen hoping through the snow, as more snow falls; a clearly defined rabbit track from a recent tracking survey.
Squirrels are another of our smaller mammalian forest friends that remain relatively abundant throughout the winter. While the ground squirrels are staying cozy hibernating, Douglas squirrels and Western gray squirrels remain hard at work throughout the winter.
From the top: A Douglas squirrel perches in a tree; a Western gray squirrel scampers across a log; a Douglas squirrel bounds through the snow; squirrel tracks in the snow photographed on a recent group tracking survey.
Our smallest visitor this month was another adorable rodent- a little mouse! If you look closely at the picture below, you can see their little eyes shinning inside the bait box!

Who goes there?! Below are some of the recent wildlife findings that we have not been able to identify. Ah, the thrill of a good mystery! There may not be enough information in these photos to properly identify these creatures, but boy do we love to speculate! Be sure to comment or send us a message at email@example.com if you get a hunch about who we are looking at here!
From the top: A mystery mammal hops across a log before sitting and staring towards the camera; an unknown shadowy creature crosses a clearly; tracks in the snow in front of a trail camera- but there's no animal to be seen.
P.S. A trusted informant proposed that the tracks in the bottom photo may belong to a grouse, based on how short the stride is relative to the size of the track. Let us know if you agree!
Winter is coming!
The winter Solstice is right around the corner, but with the storms and snow of the last week it certainly feels as though winter has already arrived here in the Pacific Northwest. Our winter wildlife surveys are in full swing, volunteers on our tracking and camera crews are busting out their snow shoes and puffy jackets and braving the elements to bring us some amazing wildlife findings!
This winter Cascadia Wild is partnering with ODFW to take part in the Western States Wolverine Occupancy Survey! This multi-state, multi-agency survey effort aims to determine the current distribution of wolverines in the western United States. Cascadia Wild is honored to be participating in this survey, the results of which will undoubtably have important implications for the future management and conservation of wolverines. Who knows, this could even be the year wolverines return to Oregon!
With the coming of winter, we expect to see some behavioral changes in many of the wildlife species found on Mount Hood. For example, deer tend to move to lower elevations in search of better foraging opportunities. Often times this results in the movement of larger predators that prey upon deer, such as coyotes and mountain lions, to lower elevations as well. In addition to the movement of deer and some predators, we also typically see less bears at our higher elevation sites, as they hunker down for a deep sleep over the winter. At lower elevations where the winter is not as extreme, bears can be active all winter.
We are excited to share the best of our winter camera and tracking surveys so far! Without further ado, let's get into it!
Perhaps our most unusual finding over the last month was this owl and deer interaction captured on one of our trail cameras!
An owl crouched on the forest floor is disturbed by a passing buck.
We don't often get trail camera footage of owls, and certainly not ones that are this clear. Trail cameras give us this amazing opportunity to peak into the lives of wildlife living in the forests nearby- we feel extra lucky to have witnessed this interspecies interaction!
We had a lot of other deer detections this month- at sites across the elevation gradient on Mount Hood. This will likely change as snow begins to accumulate at higher elevations! In addition to the changes in deer distribution during the winter months, deers diet will also change. In the summer deer mainly subsist on grasses and forbs (herbaceous flowering plants) but in the winter will begin to rely more heavily on woody plants.
From the top: A young deer with small budding antlers looks into the camera;Three deer are seen foraging in an open meadow; a buck with a large rack pauses in the middle of the camera site.
We also had a few detections of elk this month. Elk cows and calves move together in large herds through the winter, while bulls are more likely to strike out on their own after the breeding season.
An elk herd comes barreling through a camera site!
Elk belong to the same family as deer (Cervidae), they are both hoofed, ruminant mammals. Ruminants are hoofed herbivores that have four compartments in their stomachs! In one of these compartments -the rumen- plant material is fermented by symbiotic microbes. Plant cell walls are made up of cellulose, which can't be digested without the assistance of these little gut microbes! After being processed in the rumen and reticulum, food is regurgitated as cud and then re-digested. This time it will pass through all 4 compartments and be excreted as poop! Speaking of elk poop *ahem* scat, as those of us in the tracking field like to call it- check out this picture of elk scat our trackers found on a recent survey!
Scat found on a recent tracking survey, likely from an elk.
A recent tracking survey also found what is likely coyote scat!
Coyotes are opportunistic omnivores- they will eat berries, fungi, insects, fish, small mammals and fawns, depending on what is available. Our trackers weren't able to find the plant that produced these berries in the field but did some serious sleuthing back at home and determined that they likely belonged to the Arctostaphylos genus.
We also had several coyote detections on our trail cameras over the past month!
From the top: Two curious coyotes sniff around a baited log at night; a coyote checks out a camera site; a coyote gives a bait box on a tree a quick sniff.
Coyotes weren't the only large carnivores we spotted in the forest this month. We also had bobcat and bear detections at several sites.
Bobcats consume mostly small mammals such a snowshoe hare, rabbits and squirrels. Their diet remains fairly consistent throughout the year.
A bobcat on the prowl!
Black bears, the only bear found in Oregon, are considered to be the "least carnivorous" of the large carnivores. Black bears eat berries, fruit, herbaceous vegetation, insects and occasionally fawns or carrion. Black bears typically gorge themselves during the fall (eating up to 20,000 calories a day!) and then live off their fat reserves during their winter dormancy.
From the top: A black bear gets groovy rubbing up against a tree; A black bear stares into the camera; Two bears, a mama and her cub, come padding through the forest.
The smallest of the carnivores we spotted this month was this little weasel!
A weasel bounds through a camera site.
We have both short tailed and long tailed weasels in Oregon. Both are carnivorous, but short-tailed weasels dine primarily on mouse-sized prey, while long tailed weasels hunt slightly larger prey, such as ground squirrels or mountain beavers.
Speaking of squirrels! We saw lots of squirrels at our camera sites this past month. Ground squirrels are most likely snuggled up enjoying a cozy hibernation by now. However we saw plenty of Western gray squirrels, Douglas squirrels and even some Northern flying squirrels, all of which will remain active throughout the winter.

That's all we have to share with you this month but we will be back in the new year with more wildlife findings! We wish all of you a joyous holiday season and a happy New Year!
It's that time of year! A BIG thanks to all of our wonderful summer volunteers who made this season such a smashing success. Summer is a great time for viewing wildlife- we saw animals hunting, foraging, mating, and raising their young! This season has proven to us that theres nothing cuter then a baby bobcat (unless it's a baby bear...or deer). We have a lot of exciting wildlife sightings to share with you- including a sighting of one of our target species (the elusive pacific marten) and a first detection ever for Cascadia Wild (check out the badger below!). So without further ado, lets dive in!
This Pacific marten was our only target species caught on camera this season! That doesn't mean that our other target species aren't out there (Sierra Nevada red fox, gray wolf, wolverine), as evidenced by the scat and tracks shown below! While we have yet to see sight or sign of our namesake, the wolverine, we remain hopeful that they will return to their historic natural range, which includes the Oregon Cascades.
The Pacific marten is considered an indicator species of high-quality, high-elevation old growth coniferous forest. This is because they require lots of connected, complex old growth forest in order to thrive. Downed trees and standing snags, along with thick evergreen canopy, (all elements of complex old growth forest structure) provides excellent hunting and denning opportunities for Pacific marten. When snow falls, they rely on small pockets formed amongst fallen trees for thermoregulation while resting.

Signs of our other target species (Sierra Nevada red fox and grey wolf) were discovered over the summer by our awesome volunteer trackers! While we can't say for sure- the tracks below are likely those of a Sierra Nevada red fox. One way Sierra Nevada red fox tracks can be identified is by their small, linear heel-pad, which can be seen in the top track in this photo. In addition, the shape of the track and the distinct X -shape seen in the negative space tells us that this is a canine track.
A potential Sierra Nevada red fox track, discovered by one of our tracking volunteers.
Below is a possible Sierra Nevada red fox scat found by one of our volunteer trackers. For red fox, we look for scat that is less than half an inch in diameter, and is twisty and tapered at the end. This scat has a lot of hair in it, which is consistent with a red foxes diet!
Potential Sierra Nevada red fox scat- note the tapered ends and small diameter.
Finally, the scat below likely belongs to our target species the gray wolf. Gray wolf scat can be hard to identify- but like other canines we generally look for scat that is twisted, with tapered ends. We expect gray wolf scat to be significantly larger than coyote or red fox scat.
Potential gray wolf scat- this scat is pretty big, and has lots of fur in it!
We detected lots of coyotes this summer, and I mean lots! This makes sense, since coyotes are the most abundant wild canine in the Pacific Northwest. Coyote are an incredibly adaptable species-as unsettled natural area decreases, coyotes are increasingly found living in urban and suburban areas. While there's nothing quite like watching a coyote strut down the sidewalk at six in the morning, it's a treat to see what they are up to in a more natural setting!
From top to bottom: A coyote pauses on a ridge-line, a coyote rolling near a bait site, a coyote urinating near a bait site, a coyote laying down near a tree, and two coyotes sniffing around one of our camera sites.
We saw coyotes looking majestic on mountaintops, rolling on the forest floor, and marking near our bait sites! Lots of species are drawn to our camera sites due to the funky combination of scents we use as bait. Some- like these coyotes- feel compelled to roll in this stinky mixture or add their own scent to the area by urinating nearby.
We had our first badger detection ever this month! It's not surprising that we haven't had many badger sightings before- the American badger range in Oregon is east of the Cascades, and generally outside our survey area. In addition- badgers are notoriously solitary creatures that spend much of their time in dens underground, which makes this sighting all the more special!
A badger at night walking around a tree.
Badgers have been known to engage in mutualistic relationships with coyotes! Many Native tribes in North America have stories of this unlikely friendship between coyote and badger. They have been documented hunting together- coyotes are able to catch prey that badgers chase out of burrows, and badgers catch the prey that coyotes scare underground.
Up next we have the felines! The big cat below is known by many names: mountain lion, cougar, panther, and puma! They are sleek and shy, rarely are they seen by people. This summer we saw mountain lions at only four of our camera sites!
From top to bottom: A mountain lions eyes glow in the night, a muscular mountain lion strides through a camera site.
The other felid found roaming our forests is the bobcat!
A female bobcat and her playful cubs pass by.
This summer we had the joy of watching this little family of bobcats pass by one of our camera sites. Bobcat babies are typically born in May and stay with their mom until fall, although some wait until the following spring to disperse. These kittens are likely just a few months old in this photo, but by the time you're reading this they will be practically grown!
One of our cameras caught this particularly stunning photo of a bobcat cruising through the forest.

We saw some big ol' bears this summer (and some teeny ones too!). Bears were seen at 70% of our sites!
From top to bottom: A black bear walking through a burn area, a bear climbing a tree, a bear looking into the camera, and a female bear seen at night with her two cubs.
We saw bears strolling through burn areas and climbing trees. We saw bears see us (our camera, that is!) and bears with their babies! Black bears breed in the summer months, and then give birth in late January or early February in their den. Contrary to popular belief, bears aren't true hibernators. What they do could be more accurately described as entering a semi-dormant state. Hibernation involves an animal lowering their body temperature and metabolic rate, to the extent that they become unresponsive to outside stimulus. While bears do lower their body temperature and slow metabolic processes while denning, they remain responsive throughout the winter.
Striped skunks made an appearance at several of our sites throughout the summer, typically under the cover of darkness.
From top to bottom: A skunk lifting up his tail, and a skunk walking through the forest during the day.
Skunks are nocturnal, so catching this skunk during the daylight hours was a rare treat!
Our last carnivore is significantly smaller than the rest, and can be easy to miss! Although we had a few sightings of the weasel throughout the summer, they were usually just a blur across the camera site.
A weasel paused on top of a rock in the center of the frame.
Ungulates are a diverse clade of hoofed animals. The ungulates found here in the Pacific Northwest are deer and elk. Deer were seen at 95% of our camera sites this summer.
From top to bottom: a deer and her fawn browsing on herbaceous plants, a buck showing off his gorgeous rack, and a mother deer with her curious fawns.
Elk are the larger of the two ungulate species we find in this region. There are two subspecies of elk found in the Pacific Northwest- Rocky Mountain elk and Roosevelt elk. Roosevelt elk are primarily found in the coastal region and western slopes of the Cascades, while the Rocky Mountain elk are more commonly found east of the Cascade range.
In the top photo, the young bull elk gazes off into the distance. The photo right below shows an older bull. The last photo is of an elk passing by one of our camera sites late last spring.
While a few of our camera sites had small herds of elk pass through, some of the most beautiful shots we captured this summer featured elk on their own. Elk shed their antlers every winter, and regrow them in the spring. Antlers grow at an incredibly fast rate- for elk its about an inch a day! In the first photo, the young bull elks antlers are just starting to come in, and are still covered in velvet. The velvet is dense fur that helps to increase oxygen supply to the antlers. Once the antlers are fully grown, like in the next photo, elk will remove the velvet by rubbing their antlers on trees and vegetation.
Our cameras aren't set up to catch small mammals like these, but that doesn't stop them from making many appearances throughout the summer!
We saw Snowshoe hare, rocking their brown summer coats, at four of our camera sites this summer. In the winter, snowshoe hares coats turn white. This helps them to blend in with the snow, and may also increase the amount of heat they are able to absorb from solar energy.
From top to bottom: A snowshoe hare pauses in the foreground of the photo, video of a snowshoe hare bounding through the forest.
The yellow-bellied marmot is our only marmot species in Oregon. We only detected the yellow-bellied marmot at one high elevation site this summer! East of the Cascades, they can be found at lower elevations as they can live in both montane or arid environments. Marmots are true hibernators, by now they are probably snuggled up in their burrows, not to be seen again until spring!
A yellow-bellied marmot strikes a pose on a rock.
There are several species of squirrels found in our forests. These curious critters are always up to something!
From top to bottom: A Douglas squirrel climbing a tree, the California ground squirrel gathering some vegetation, the Eastern gray squirrel showing off its fluffy tail, the Northern flying squirrel gliding across the forest floor, and the golden mantle ground squirrel having a snack.
Douglas squirrel, like the one in the first picture, are one of the smallest squirrels in Oregon, Douglas squirrels can be identified by their small size and tan bellies. Up next we have an industrious California ground squirrel. In the colder parts of their range (such as here in the Cascades), California ground squirrels hibernate during the winter, so we don't expect to see many of them in the coming months! The next squirrel is easily identified by its long gray, bushy tail- its the Eastern gray squirrel! The squirrel seen gliding across the forest floor in the next image is the Northern flying squirrel. These little forest friends use a fold of their skin, called the patagium, that connects their hind and forelimbs in order to gracefully glide through the forest. Our final squirrel sighting is the golden mantle ground squirrel! These tiny squirrels look a lot like chipmunks. One easy way to tell them apart is that golden mantle ground squirrels lack face stripes. Check out the chipmunk below for comparison!
A chipmunk perches on a branch next to our trail camera.
See those face stripes? This chipmunk was a frequent visitor at one of our sites, and seemed to really enjoy that particular branch for taking a rest and a snack!
The last of our small mammals is the delightful bushy-tailed woodrat. If you look closely in the picture below, you can see how this critter got its name!

Birds and Bats
We had some amazing bird sightings this summer including raptors, owls, bats and ground birds, along with some more common backyard birds! The raptors below are red-tailed hawks.
From the top: A red-tailed hawk comes in for a landing, showing off their beautiful tail feathers. A red-tailed hawks spread wings can be seen in the second photo.
We only had a couple owl sightings this summer. We typically capture images of owls at night, and they can be hard to make out, but below is a picture of an owl captured during the daytime!
An owl comes in for landing on a fallen log.
Like owls, we only expect to get photos of bats after it's dark. The photo below is our one and only bat detection from this summer!
A blurry bat flies through the night.
We had several turkey sightings over the summer. The picture below is the only time we captured a male turkey strutting.

This was our one and only grouse detection all summer!

We also saw some more common backyard birds out in the woods! Including this raven that landed at one of our camera sites.
This beautiful Stellar's jay stopped by on a sunny day.

Those are the highlights from an incredible summer season! Check back in next month to see what we discover with out winter camera sights and our winter tracking crew!
