Abstract:A 26-year record of 12 plantations in the Douglas-fir region shows that the planted trees continue to die in considerable numbers from a variety of causes long after the period of establishment. This mortality rate is something that the planter should know and reckon with. In addition to actual losses there is considerable mutilation of surviving trees which is an appreciable factor in lowering quality in widely spaced plantations.
