A fuelbreak in the black spruce forests. Fuelbreaks are great at preventing fires from spreading, but removing trees has serious ecological implications.


The author uses vegetation plots to study which species return first in cut Black Spruce forests.


The dense Black Spruce forests at the Bonanza Creek LTER—Christmas Trees, if you will.


Research at the BNZ LTER is pretty in a photo, but buzzing with mosquitos during the summer months.


Another example of what my pitfall traps look like after a bear encounter.


Mom and two cubs crossing the road near one of my field sites.


The bears pull my traps out of the ground and then eat and/or spill the contents before tossing the cups aside. (Normally the white plate would be held over the pitfall trap with the plastic nails to act as a rain cover).
