Growth, Survival, and Microclimate of Conifers Planted Within Forest Gaps by Peter Fielder Pdf

seasons (April 1-October 31) are presented for both sites. Maximum T at GS10 and HU10 was approximately 0.8 and 0.7, respectively, and minimum levels in the understorey declined to less than 0.05 at both sites on the south side of the gaps. Growth on the sites was affected by both soil moisture and vapour pressure deficit. An additive model was used to incorporate the moisture variables with T estimates to model the effect of light on growth, although replication was considered insufficient for statistical comparisons between the two sites. Growth tended to increase to a maximum at T values of approximately 0.3 and 0.8 for western hemlock (Tsuga heterophylla [Raf.] Sarg.) and western redcedar (Thuja plicata Donn.), respectively, and did not reach a maximum at approximately 0.8 above-canopy light for Douglas-fir (Psuedotsuga menziesii [Mirbel] Franco) and western white pine (Pinus monticola Dougl.). Light modelling with TASS III revealed both differences and similarities between the mod

The Effects of Site Preparation and Harvesting Practices on Planted Seedling Productivity and Microenvironment in Southern Interior Dry, Grassy IDF Forests by Jean Heineman,British Columbia. Forest Science Program,J. Heineman Forestry Consulting Pdf

Dry, pinegrass-dominated sites in the interior Douglas fir (IDF) zone of southern interior British Columbia are challenging to regenerate, despite ongoing improvements in nursery & silviculture practices. Using results from three separate studies, this report discusses conifer seedling survival & growth responses to silvicultural systems & site preparation treatments that were applied to relieve harsh site conditions at Fehr Mountain, Murray Creek, and Opax Mountain. To help interpret these responses, the effects of silvicultural system & site preparation treatments on seedling microenvironment are also analyzed with reference to the following factors: soil water, air temperature, soil temperature, light, nutrient availability, soil physical properties, and ectomycorrhizae.

Size- and Age-Related Changes in Tree Structure and Function by Frederick C. Meinzer,Barbara Lachenbruch,Todd E. Dawson Pdf

Millions of trees live and grow all around us, and we all recognize the vital role they play in the world’s ecosystems. Publicity campaigns exhort us to plant yet more. Yet until recently comparatively little was known about the root causes of the physical changes that attend their growth. Since trees typically increase in size by three to four orders of magnitude in their journey to maturity, this gap in our knowledge has been a crucial issue to address. Here at last is a synthesis of the current state of our knowledge about both the causes and consequences of ontogenetic changes in key features of tree structure and function. During their ontogeny, trees undergo numerous changes in their physiological function, the structure and mechanical properties of their wood, and overall architecture and allometry. This book examines the central interplay between these changes and tree size and age. It also explores the impact these changes can have, at the level of the individual tree, on the emerging characteristics of forest ecosystems at various stages of their development. The analysis offers an explanation for the importance of discriminating between the varied physical properties arising from the nexus of size and age, as well as highlighting the implications these ontogenetic changes have for commercial forestry and climate change. This important and timely summation of our knowledge base in this area, written by highly respected researchers, will be of huge interest, not only to researchers, but also to forest managers and silviculturists.

Small Openings in Trembling Aspen Forest by Arthur Groot,Great Lakes Forestry Centre Pdf

Describes a study of a 40-year-old trembling aspen stand to examine how microclimate influences the regeneration of white spruce and trembling aspen. In the study, openings of various sizes were created in the stand and measurements were made of microclimatological parameters and tree growth parameters. Results presented include solar radiation, soil and air temperature, humidity, and soil moisture in the various types of openings; seedling-water relationships; first- and second-year establishment ratios; effectiveness of vegetation control treatments; daytime patterns in stomatal conductance and transpiration; height and diameter growth; leaf area index; and differences in height between trees with pruned and unpruned roots.
