Abstract

To assess the fate of live trees retained in dispersed patterns across cutting units in the western Cascade Range of Oregon, we conducted repeat surveys (1993 and 2001) of sites cut as early as 1983. Our objectives in this study are to (1) survey survival and mortality of trees retained at the time of harvest, (2) describe temporal patterns of windthrow and other causes of mortality, (3) explore the relationship between site conditions and tree mortality, (4) consider a simple projection of the future fate of the retained live trees, and (5) comment on the long-term management of retained live trees.
