Trees are represented by ±, or by #, depending on your operating system and options. They are primarily found in the Ranger Quest and in Minetown.

Applying an axe in the direction of a tree will destroy it and generate a random fruit. Doing so in the line of sight of a watchman will anger him ("Halt, vandal! You're under arrest!"). Oddly enough, wands of fire will bounce off of trees. Note that the trees in the Ranger quest are petrified, and unable to be chopped down.

Kicking a tree will either generate a random fruit or summon "the former inhabitants of the tree" - i.e. killer bees.
