Abstract
Eight broad-band (BB) and 52 narrow-band (NB) spectral variables collected on single sampling dates in June, July and August of 1996 were used, either individually or over multi-temporal periods (June to July, June to August, and July to August), to evaluate their potential use in estimating key cover components (e.g. bare soil, rock, litter, lichen, moss, total live vegetation, shrubs, herbs, forbs and grasses) within a sagebrush steppe rangeland. Regression correlation coefficients ranged from a low of 0.36 and 0.42 for moss to 0.80 and 0.87 for total live vegetation, for the leading BB and NB spectral variables respectively. In general, more specific plant growth forms (e.g. grass and forb) had a poorer explicability (i.e. lower regression correlation coefficient, r) than the more general components (e.g. herbs and total live vegetation)...
