Red Squirrels are cone specialists and create massive debris piles, called middens, in areas where they regularly eat (typically atop a stump, fallen log, or low, broad tree branch). These middens are easy to spot and are often more than a meter in width. In Western Washington, these cone middens are usually created by the Red Squirrel’s cousin, the Douglas Squirrel (T. douglasii).

The caterpillars of this species will hibernate overwinter and can do so for many years before metamorphosing into adults.

Larch is one of North America’s only deciduous conifers. Here in western Montana, needles are just beginning to turn yellow in mid-September.
Bryoria is a common lichen throughout the PNW and was once a common food source for more than 40 local tribes, in spite of nearly indistinguishable toxic species co-occurring throughout most of their range.
