Zone 2 is determined by slope of land and type of vegetation.
The size of the Zone 2 defensible space is determined by the kind of natural vegetation and the slope of the land. A steep slope calls for a wider perimeter than a flat area. A grassy area with only a few trees and shrubs calls for a smaller perimeter than an area dominated by shrubs and brush. The following table will help you determine the recommended distance from your structure for Zone 2 defense measures.

Zone 2 Defense Measures
Remove dead trees, dead shrubs and accumulated dead wood
Thin out trees growing close together. Fewer trees mean less fuel for the fire.
Remove highly flammable ladder fuel shrubs and brush such as juniper, arborvitae, mugo pine, bitterbrush and sage.
