Publisher's Synopsis
Excerpt from Occurrence of Conifer Seedlings and Their Microenvironments on Disturbed Sites in Central Idaho
Seed germination and establishment depends on critical environmental conditions. A microenvironment that pro vides a seed with the requirements for germination and establishment was defined by Harper (1977) as a safe site. The absence of a particular species from an area may be due either to insufficient seed dispersed to the site or to a lack of safe sites. Silviculturists use several methods to manipulate the amount of available conifer seed, but little is known about the required safe sites for that seed. Once identified, site preparations after timber harvesting can be manipulated to provide as many safe sites as possible for a desired conifer species. This study was undertaken to define safe sites for coniferous trees in west central Idaho.
