Abstract

Emergence, establishment and growth of Abies amabilis, Pseudotsuga menziesii and Tsuga heterophylla were studied for 2 years in variously sized canopy gaps created in four stands on the west slope of the Cascade Range in central Oregon and southern Washington, USA. Seedlings originating from seeds sown on controlled microsites were compared with natural seed rain.

Keywords
