Projects that take place in forested areas are complicated by limited access, limited visibility on the ground, and thick undergrowth. Depending on the land designation, only minimal line cutting may be possible. Tall trees with a thick canopy can render most GPS systems useless for obtaining accurate 3-D positions even if the line is adequately traversable. Travel will be mainly by foot. If roads or trails are available, 4-wheel ATV's in the summer and snowmobiles in the winter can improve production. Count on snowshoeing when snow depths exceed 25 centimeters. |
