I love camera traps because they are easy to use, and it is fun to look at the results. Lock a camera to a tree, write down the GPS coordinates, and walk away for a few weeks.
Come back and you get to look at new clips of animals running around. It is rare to take a walk in the woods and actually see a mammal like a fox, but put a camera trap out and you’ll get them....
We found higher diversity and overall higher activity of animals in our camera traps set in urban forests than in those out in the wild areas.
Of course, you may "walk away" only to find your camera stolen! Set up in haste, and regret in leisure!
