ATTACHMENT 1: FIGURES AND TABLES

Figure 1. Graphic illustration of the walkthrough method. Five sample objects (+), lying close to the boundary, have been tallied from a sample point (*). The arrows indicate the layout of the walkthrough points for each object; the outcome on the key in Table 1 is indicated for each walkthrough point. Objects 1, 3, and 4 are tallied normally; objects 2 and 5 are double-tallied. Four objects (●) lie “close to the boundary” but in positions where they would be single-tallied, and no measurements would be needed. Taken from Ducey M.J., J.H. Gove and H.T. Valentine. 2004. A walkthrough solution to the boundary overlap problem.

For. Sci. 50: 427-435.

TREE_UNUS.

Appendix A: Description of Forested and Non-Forested Area Definitions

A.1 Forested area An area dominated by trees and defined as a forest, willow or cottonwood community type in USGS land cover layers. This includes areas with only standing dead trees. Specifically, to be considered forested, an area must:

1. Be a minimum of 5 contiguous acres of forested cover. Isolated patches of forest smaller than

5 acres should not be considered forested for the purposes of Phase II forest inventory.

2. Be more than 75 feet from and adjacent forest edge across an intervening non-forested area

A.2 Non-forested area Non-forested lands are defined as dominated by herbaceous and/or non-willow multiple fork shrub species and greater than 5 acres in size. Areas dominated by willow will be considered forested. To be non-forested for the purposes of Phase II forest inventory an area must:

1. Be a minimum of 5 contiguous acres of non-forested cover. Isolated patches of non-forest cover smaller than 5 acre that occur within a forested areas should be sampled as inclusions within that forested area and no special methods should be used to account for edge.

2. If a contiguous feature (i.e. a bay), the separation between adjacent forest edges should be greater than 75 feet. In cases where the separation in less than 75 feet, the area should be considered an inclusion as above and sampled as forested area up to the point at which separation becomes greater than 75 feet. At this point, sampling should include corrections for forest edge sampling, except:

3. If a contiguous, perennial water feature (i.e. a slough) completely bisects two adjacent forested areas, it should be considered non-forested regardless of width or area and protocols outlined below should be used to account for edge in both of the adjacent forested areas.
