Grass Competition Level - An excess amount of grass and forbs can out-compete trees and shrubs for water and nutrients. A scale of 0-3 is used to indicate the degree of grass competition within a 2' radius. Zero indicates there is no grass/forb competition, 1 indicates grass/forbs are within 18" of the planted stock, 2 indicates grass/forb competition within 7-12", and a 3 indicates that grass/forbs are wihtin 6" of the stem.
Source - The source of grass providing the competition is also noted, such as "pasture grass" or "forbe". In addition, a special note is made of reed canary grass or other aggressive invasives.
