ii I. Introduction
A. A T D
The purpose of this Noxious Weed Risk Assessment is to determine the risk of introducing or spreading noxious weeds through implementation of the Lassen 15 Restoration Project. In a noxious weed risk assessment, seven factors are rated for risk of introduction and spread of noxious weed species. The risks are tallied to get an overall risk for the proposed project.
