fall in aparticular direction include:
S The wind direction and speed.
S The lean of the tree. The lean of a tree
might not be apparent due to uneven or
slopingterrain. Useaplum borleveltode-
termine the direction of tree lean.
S Weight andbranches on on e side.
S Surrounding trees and obstacles.
Look for decay and rot. Ifthetrunk isrotted,
it can snap and fall toward the operator.
Make sure thereis enough roomfor the t reeto
