Abstract

Abstract

Phenologic events which may be related to yields of economic plant species in humid and sub-humid temperate regions are difficult and expensive to observe and measure. Sequential multispectral reflectance data obtained by an orbiting satellite (LANDSAT-1) over 14 preselected sites in central and eastern United States during a 14-month period were examined. Analysis of data from four reflectance bands (0.5 to 1.1 μm) indicated that foliage color, leaf senescence, and regrowth differences among hardwood timber stands can be detected and quantified. The results suggest the need for continued development of these monitoring techniques for use in detecting and quantifying conditions of economic plants which may affect yield.
