Mammoth lakes revisited—50 years after a Douglas-fir tussock moth outbreak.

Informally Refereed

Abstract

For five decades after an outbreak of Douglas-fir tussock moth (Orgyia pseudotsugata (McDunnough)), radial growth of defoliated white fir trees (Abies concolor (Gord. & Glend.) Lindl.), was significantly greater than that of nondefoliated host trees nearby. The increased growth probably was due to the thinning effect of tree mortality and increased nutrient availability.
