Book Description
Conifer Cold Hardiness provides an up-to-date synthesis by leading scientists in the study of the major physiological and environmental factors regulating cold hardiness of conifer tree species. This state-of-the-art reference comprehensively explains current understanding of conifer cold hardiness ranging from the gene to the globe and from the highly applied to the very basic. Topics addressed encompass cold hardiness from the perspectives of ecology, ecophysiology, acclimation and deacclimation, seedling production and reforestation, the impacts of biotic and abiotic factors, and methods for studying and analyzing cold hardiness. The content is relevant to geneticists, ecologists, stress physiologists, environmental and global change scientists, pathologists, advanced nursery and silvicultural practitioners, and graduate students involved in plant biology, plant physiology, horticulture and forestry with an interest in cold hardiness.

Book Description
This study was initiated in 2001 as part of a uniform shelterwood trial located in the dry, warm Sub-Boreal Spruce subzone (sbsdw) near Williams Lake, B.C., after a second harvesting entry was completed. The focus of the main trial was to test various levels of residual basal retention and harvesting methods on the establishment, survival, and productivity of Douglas-fir regeneration. The microclimate component was set up to help interpret tree performance by comparing the climate conditions among three of the residual basal area treatments (0, 15, and 20 m2/ha). The objectives for the microclimate portion of the shelterwood project were to compare soil temperatures and snow-free periods among the three residual basal area treatments (0, 15, and 20 m2/ha); to compare the incidence, duration, and severity of growing season frosts among the three residual basal area treatments (0, 15, and 20 m2/ha); and to investigate the effects of local canopy density on minimum near-ground air temperatures and duration of frost events during the growing season.--Document.

Book Description
This publication summarizes the autecological characteristics of 35 vegetation species and provides information on how they respond to various silvicultural treatments now in use on forest lands. Information used in this report was gathered in an extensive search of ecological, silvicultural, and botanical literature, most of which originates in western Canada or western US. Information is given on description, distribution and abundance, habitat, growth and development, reproduction, pests, effects on crop trees, response to disturbance or management, and wildlife and range of each species, listed alphabetically by scientific name.
