Happy Spring! While snow and cold will linger around the mountain for a bit, there​ is an undeniable warmth on the breeze. In the valleys, buds are bursting on trees, spring ephemerals are opening to greet the season, and we welcome all the new growth that this season brings!
At Cascadia Wild, we are celebrating the season with offerings of Spring Botany Classes and a new Tracking Challenge!
Our Plant Identification Class will help you learn to identify all the local, wild plants that are emerging. Learn some of the basics of plant identification, including botany terminology, plant families, identification traits, and growth habits of plants. This class combines guided exploration on your own at a local park with an online class discussion. Learn more: ​

Also, check out the current Tracking Challenge - Carnivores! Our latest post explores the importance of carnivores in an ecosystem, carnivore families, and tracks and sign to look for. We hope you are inspired to get out and go tracking! As always, send us what you find and any of your tracking questions.

Meanwhile, winter's not over yet for the Wolverine Tracking Project! Read on for our latest findings from our winter wildlife camera and tracking surveys.

wildlife Camera and Tracking surveys

We've had a couple detections - and a couple possible detections - of target species this month!
We are excited to share this camera footage of one target species, the Sierra Nevada red fox:

We had two separate detections from this camera in the same night, a few hours apart. It is impossible to say whether this is the same individual without genetic evidence, but in both instances the fox in frame was cute and curious! If the sightings are of two separate individuals (of opposite sexes) we hope they are a pair. These images were taken during red fox mating season (January and February), and kits conceived during these winter months will be born between March and May. 

A Tracking Leader also recently found some tracks that could possibly belong to a Sierra Nevada red fox:
Picture
Picture
Left to right (or top to bottom): A canine trail up a snowy hill on Mt. Hood; a canine track in deep snow is carefully measured.
The trail pattern and size of these tracks are right on for fox tracks. However, these characteristics could also indicate that these tracks were made by a coyote or domestic dog. Unfortunately, due to less than ideal snow quality, it is difficult to look for more differentiating characteristics. In an ideal tracking scenario we would look at the shape of the negative space between the toes and heel pad. In domestic dogs and coyotes, this negative space is shaped like an "X". In red foxes, this shape is an "H". This print is a double register - meaning the hind foot has stepped on top of the front print, obscuring the details of the front track. If we could clearly see the front track, we could also look at the shape of the heel pad. In coyotes and dogs, this shape is trapezoidal; on foxes, the heel pad is more "squished" looking and can show up looking more like a horizontal line.

For now, we'll have to log this track as "canine" - no matter how excited we might be about the possibility of detecting our most elusive montane fox!

This tracker also found some potential Sierra Nevada red fox scat on the same survey: 
Picture

This scat has a dramatic tapered end and is about as thick as your pinky finger, which are both good indicators for fox. However, like the tracks found nearby, the scat is also a little formless which could be due to age, diet, or even the snow. It's hard to know who this scat belongs to based on visual clues alone, but this sample was collected and genetic analysis can tell us for sure. 
One of our long-time volunteers also sent us these canine tracks, which may belong to another target species, the gray wolf:
Picture

Left to right (or top to bottom): A trail of probable wolf prints leads off through the snow; a probable wolf print shown up close.
When considering canine tracks that may belong to a wolf, the most important consideration is size. Wolf tracks are larger than coyote tracks and much, much larger than foxes. They are also much larger than most domestic dogs, except for large breeds like Great Dane, Mastiff, and Rottweiler. And so, determining who these tracks belong to requires differentiating between large domestic dog tracks and wolf tracks. 

Compared to domestic dog tracks, wolf tracks typically show a greater distance between the two outer toes (the interdigital space). The toes also point straight ahead instead of out, like they tend to do in dog tracks. Claws are long and pronounced, and thinner than in dog tracks. Wolf tracks also show a longer track with a proportionally smaller heel pad, and the track will show a downward angle in the direction the wolf is traveling, since they do not walk as flat footed as dogs do.

Like our possible fox tracks above, however, we don't have enough details to say for sure that these belong to a wolf and not a domestic dog. Details of the trail pattern and context would also be helpful to confirm an identification. Thus, we can only say that these are probable wolf tracks - but still an encouraging sighting nonetheless!​
We also detected another target species - and this time we are sure of it! These photos below show the fierce mustelid, Pacific marten.

Left to right and top to bottom: Several detections show a Pacific marten approaching the bait tree in the center of a snowy camera site. It is unclear if these are the same or different individuals each time.
The photos above are from three separate detections of marten at this same site, where they have also been detected throughout the season. Like the Sierra Nevada red fox, we can't know for certain if this is the same individual without genetic data. Martens spend the winter roaming and hunting alone, and the territories of males will overlap with those of females, but males defend their territories against other males. So if these are separate individuals, they may be polygynous partners.
This magnificent mountain lion was also documented:

A rare detection in the mountains in winter, this is the third sighting of a mountain lion at this location this winter. The camera crew even found fresh mountain lion tracks at the site at each camera check! Oregon has a healthy population of about 6,000 mountain lions. Hunting regulations were instituted in 1961, after the population had been decimated to approximately 200 individuals, and thankfully they have since rebounded. 
Another feline was also detected, the bobcat! The two white spots which visible on the back of their ears are thought to be false eyes which deter predators. Such distinctive markings (as well as the white underside of their tail) may also help trailing cubs follow their mother.

Bobcats have classic feline tracks, with toes that sit in a curve above the heel pad, allowing the space between the toes and heel pad to form a C shape. With a length of 2 1/2 inches, these tracks are too small to belong to a cougar but are just the size you would expect for a bobcat.

Coyotes were regular visitors by night and day, as they have been throughout the winter season.

​The camera sites also documented many, many deer, exemplifying a diversity of age and size found between deer and even within the same herd.

Elk also roam the forest. They sometimes appear on our trail cameras solo, but they can appear in quite large herds, too - especially this time of year.

Although snowshoe hares are common sights on our trail cameras, their quantity does not diminish their quality. 
Picture

Snowshoe hares are an incredibly important prey species for many omnivores and carnivores, like two of our target species, Sierra Nevada red fox and gray wolf. In fact, they are such an integral part of the food chain that their population size can directly affect the population of predators in the area. But to catch a snowshoe hare, a hopeful carnivore must have keen eyes and quick paws. In winter, the coats of snowshoe hares often turn from brown to white, to help them blend into the snowy world around them. Also, snowshoe hares can cover up to 10 feet of distance in a single bound, and they can bound away from carnivores at a top speed of 27 miles per hour!

Other important prey species include the the California ground squirrel,
western gray squirrel, and the Douglas squirrel.

California ground squirrels are known to hibernate during winter, but can emerge from their winter sleep as early as January, though some are not seen until March. Looks like this one in the first photo is an earlier riser! Western gray squirrels and Douglas squirrels are active all winter. In the second photo, we can see two gray squirrels chasing each other - either in a territorial or mating display. 
We also detected striped skunks ​wandering by a couple of our cameras.

We also detected a couple turkeys!

We hope you are able to get out and enjoy a leisurely, spring stroll through the woods, too.
