Increased Growth of White Fir After a Douglas-fir Tussock Moth Outbreak
Abstract:For 36 years 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 non-defoliated host trees nearby. The increased growth was probably due to the thinning effect of tree mortality and increased nutrient cycling.
