GLOSSARY resource value ratings. Trends in resource value ratings for several uses on the same site at a given time may be in different directions, and there is no necessary correlation between trends in resource value ratings and the trend in ecological status. understory: plants growing beneath the canopy of other plants; usually refers to grasses, forbs, and low shrubs under a tree or shrub canopy. U unsuitable rangeland: rangeland which has no potential value for, or which should not be used for, a specific use because of permanent physical or biological restrictions. When unsuitable rangeland is identified, the identification must specify what use or uses are unsuitable (e.g., “unsuitable for cattle grazing”). useable forage: that portion of forage that can be grazed without damage to the basic resources; may vary with season of use, species, and associated species. utilization: the proportion or degree of the current year’s forage production by weight that is consumed or destroyed by animals (including insects). The term may refer either to a single plant species, a group of species, or the vegetation community as a whole. Utilization is synonymous with use. vegetation: plants in general, or the sum total of the plant life above and below ground in an area. V vegetation hit: a point on vegetation, either basal or canopy, where the tip of the pin or the crosshairs in a sighting device intersect a leaf, stem, or other portion of the plant. Lichens and mosses must exceed 1/16 of an inch in thickness to qualify as a vegetation hit. Lichens and mosses less than 1/16-inch in thickness growing on rock are considered as rock; if they are growing on bare ground, they are considered as persistent litter. vegetation type: a kind of existing plant community with distinguishable characteristics described in terms of the present vegetation that dominates the aspect or physiognomy of the area. vigor: relates to the relative robustness of a plant in comparison to other individuals of the same species. It is reflected primarily by the size of a plant and its parts in relation to its age and the environment in which it is growing. W warm season species: plants whose major growth occurs during the spring, summer, or fall and that are usually dormant in winter. wet meadow: a meadow where the surface remains wet or moist throughout the summer, usually characterized by sedges and rushes. 137
