WELCOME TO A NEW YEAR
Happy New Year! 2022 was a great year for us. We saw so many amazing animal photos retrieved from our cameras, and fascinating tracks and sign of animals on our tracking surveys. We were so excited to get some target species detections in the past year, including several red fox camera sightings, as well as finding marten tracks. We are excited to see what 2023 brings! Thank you to everyone that has supported us over the past year.
We had three tracking surveys in December, and our volunteers saw track and sign of a variety of animals. Let's take a look at some of the last tracks they found before ringing in the New Year!
While trekking through the snow at Mt. Hood, some of the most common tracks to find belong to Douglas squirrels and snowshoe hares. These animals are always on the move, looking for plant matter to eat amongst all of the snow.
Luckily, these animals both have fairly distinct gaits that we can learn to identify! Below is a Douglas squirrel trail. These animals hop forward, with their rear feet swinging around their front feet and landing slightly ahead of where their front feet are planted. Additionally, if the prints are clear enough to make out toes, you will see four toes on the front feet of a Douglas squirrel and five toes on the rear feet.

Next let's look at a snowshoe hare trail. Like the Douglas squirrel, these animals hop forward with their rear feet landing ahead of their front feet. One difference we can see from the squirrel trail, however, is that a snowshoe hare's front feet will land one slightly in front of the other, rather than side by side. This allows the hare to have more stability while moving quickly. With that pattern and such large rear footprints, a snowshoe hare trail is often easy to identify once you know what to look for!

Now you know how to identify two of the more common tracks you might see at Mt. Hood! While our volunteers saw tons of these tracks in December, they also saw some more unique track and sign. Let's take a look at some other highlights!
Here is another sign of squirrel. One must have been sitting in this tree while eating something, and all of its scraps fell to the ground below!

Our volunteers also found evidence of an even smaller critter! A deer mouse left this trough-shaped trail through the snow, before scurrying down into a tunnel below the snow. These tunnels give the mouse a better chance of going undetected by predators.

Our volunteers also found some tracks belonging to members of the mustelid family! These animals generally have long bodies that are low to the ground. Mustelid feet have five toes, and they move with a unique bounding gait. This gait also has the rear feet landing in nearly the same spot as the front feet.
First, we have a weasel trail. These could be from a short-tailed or long-tailed weasel, but they can overlap in size, so it can be hard to positively identify. It looks like the feet overlapped a bit in some spots as well.

Volunteers also found a marten trail! This is a Wolverine Tracking Project target species, as there is a healthy population at Mt. Hood and they are good indicators of forest health. For this trail, you can see a similar gait to the previous weasel. We have also included a single track, where you can see how the feet landed in similar spots and are overlapping.

Those are just some of the animals that volunteers might cross paths with on a tracking survey. Check back in next month to see what else they find!
