Winter wildlife review

5/2/2020

0 Comments

 
The days are getting warmer and longer, the birds are returning from winter migration, and animals everywhere are bringing a new generation of wildlife into our forests...needless to say, winter has ceased and made way for spring, marking the end of our winter survey season. While this season may have been unexpectedly cut short, the Cascadia Wild team of volunteers and members still managed to bring in countless wonderful photos and record many wildlife tracks while it lasted.

Please enjoy this season recap of the Wolverine Tracking Project's Camera and Tracking Survey highlights!

CAMERA SURVEYS

Picture
This winter season, a total of 1,447 volunteer hours went into camera survey trips!​
Picture
Together, we maintained a total of 21 cameras at 25 camera sites over the winter season.
Over the survey year (which ran from Summer 2019 through Winter 2019-20), our camera sites were divided into two general areas: those near Mt. Hood, and those near the eastern edge of the National Forest boundary, with the intention of targeting different kinds of animals. 
Picture
This map shows the cameras from the past year in the Mt. Hood area Summer 2019 and Winter 2019-20. The red dots are summer camera locations, the green dots are winter camera locations, and the black dots are year-round cameras.

Picture
This map shows the cameras in the eastern forest boundary area Summer 2019 and Winter 2019-20. The red dots are summer camera locations, the green dots are winter camera locations, and the black dots are year-round cameras.
The tables below show the animals detected at each site over the winter season:
Picture
Picture
A total of 18 different animal species were detected by our cameras, along with a few mystery species pictured below...
Picture
Picture
Picture
Picture
Our cameras even captured 3 different target species!

The beautiful Sierra Nevada red fox was pictured at 4 separate camera sites this winter!
Picture
Picture
Picture
Picture
Picture
Another target species, the gray wolf, was seen at 2 camera sites...
Picture
And our final target species was pictured at one camera site: the Pacific marten!
Picture
While these target species are incredibly exciting to capture on camera, so are the many other animals that passed through our camera sites!
​
Our most frequent visitor was present at over 64% of all camera sites this winter... You guessed it: the coyote!
Picture
Picture
Picture
Picture
Another frequent visitor was the black-tailed deer, present at 52% of our overall camera sites, and over 92% of the eastern forest boundary sites!
Picture
Picture
Picture
Deer weren't the only ungulates spotted in our forests this winter. Elk were present at 5 different camera sites, all in the eastern forest boundary:
Picture
Picture
Picture
Appearing at 10 camera sites, the bobcat was another regular:
Picture
Picture
Picture
Picture
The largest felid in our forests, the mountain lion, was present at only 1 camera site this winter:
Picture
The black bear was seen at 2 camera sites this winter, including once with some cubs!
Picture
Picture
Many forest rodent inhabitants made their way into our camera sites, such as squirrels and mice.
Can you spot tell which is a Douglas squirrel and which is our native, nocturnal Northern flying squirrel below?
Picture
Picture
Picture
Snowshoe hares were present at 8 camera sites...
Picture
Picture
And luckily, we only faced minor sabotage by the striped skunks, who made their way into 5 different camera sites...
Picture
Picture
Picture
A huge THANK YOU to all of the volunteers that made this winter season so great - we look forward to another great summer survey season!

tracking surveys

Picture
This winter season, a total of 1,213.5 volunteer hours were put into tracking surveys! ​
Picture
Picture
Picture
In total, 47.5 miles were surveyed for tracks at 11 different transect locations! 
The map below shows the locations of our tracking trips this season.
Picture
Thanks to all your hard work and attentive tracking, 279 total tracks were recorded, consisting of 8 different species and some mystery tracks!

This table shows our tracking totals for the winter season:
Picture
By and large, our winter tracks were dominated by snowshoe hare and squirrel prints.
Pictured below are squirrel tracks (left) alongside snowshoe hare tracks (right).
Picture
This season, a total of 117 squirrel tracks were recorded, the most of any species this season!
Picture
Picture
Second in frequency to squirrel were snowshoe hare, with a total of 113 tracks!
Picture
Picture
Picture
Another frequent sight on these tracking surveys was the deer mouse, with a total of 21 tracks recorded.
Picture
Picture
Weasel tracks were recorded a total of 13 times​:
Picture
Our tracking teams even picked up a target species: the Pacific marten!
Picture
Picture
A total of 6 coyote tracks were seen...
Picture
...and a total of 9 bobcat tracks
Picture
Picture
Our volunteers also found some beautiful raven tracks in the snow!
Picture
​Some mystery tracks were not clear enough to properly identify...
Picture
Along with animal tracks, our wildlife tracking teams also found other signs of wildlife in our forests, including these small sticks that indicate a small animal chewing the cambium for food...
Picture
...and a tree with signs of bark removal at the base (perhaps from a bear eating the cambium), consumption of the exposed inner tree by insects, and finally, marks left by a woodpecker eating the insects inside the tree.
​So much history visible in one tree!
Picture
Near the base of this sign post are marks left by a bear:
Picture
Our tracking teams also found a small mystery den:
Picture
Picture
With so many animal signs recorded - both tracks and otherwise - it has undoubtedly been a very successful winter tracking season!
