Try to cut down (tap) all of the trees without cutting down the home of a spotted owl. If there are no owls nearby, a wider space will open up. If you think you know where one of six spotted owls are living, tap the flag and then click on its home to preserve it with a flag. After all of the harvest-able trees not having owls are tapped, everyone wins! However, if you chop down an owl's home then everyone loses.
