Forest, Edge and Opening Microclimate at Sicamous Creek by David Leslie Spittlehouse,Rita Dorit Winkler,Ralph Sidney Adams,British Columbia. Forest Science Program Pdf

The study described in this report is part of a larger project intended to address concerns about the effects of clear-cut harvesting on high-elevation forests in southern interior British Columbia. The study investigated microclimatic conditions in mature forest and in clear-cuts of 0.1 to 10 hectares. Parameters measured include solar radiation, ultraviolet-B radiation, energy balance (fluxes of net radiation, soil heat, sensible heat, & water vapour), wind speed, precipitation & snow melt, and air & soil temperature. Results compare measurements made in forests with those made in the openings. Implications of the findings for plants & for forest hydrology are discussed.

Spatial Heterogeneity of Forest-Steppes by Laszlo Erdos Pdf

Forest-steppes occupy a wide zone between Eurasian closed canopy forests and open steppes and feature a mosaic of woody and herbaceous vegetation. Due to the occurrence of structurally, compositionally, and environmentally strongly different habitats in close proximity, high spatial heterogeneity is one of the key characteristics of forest-steppe ecosystems. This volume presents ten contributions examining forest-steppe heterogeneity and its effects on environmental factors, plant communities, and animals.

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

Microclimate Studies in Mountain Pine Beetle-damaged Silvicultural Systems on the Chilcotin Plateau by Robert Matthew Sagar,M. J. Waterhouse Pdf

The objectives of this study were to: 1. compare the key environmental variables between blocks (elevational effect) and treatments (clearcut and irregular group shelterwood with whole-tree harvesting partial cut), and between microsites within partial cut openings (north and south edges and centre); and 2. examine temporal changes occurring to environmental variables in the context of the changing biological environment. This document includes an introduction, methods, results and discussion, and a summary.--Includes text from document.

Microclimate Studies in Silvicultural Systems on the Chilcotin Plateau of British Columbia by Robert Matthew Sagar,M. J. Waterhouse,Chapman Bill,British Columbia. Forest Science Program Pdf

Group selection and irregular group shelterwood silvicultural systems are being tested as options to conserve woodland caribou (Rangifer tarandus caribou) habitat. If successful, the systems will be applied within the very dry, cold Sub-Boreal Pine-Spruce (SBPSxc) and very dry, very cold Montane Spruce (MSxv) biogeoclimatic subzones, located on the high-elevation Chilcotin Plateau of west-central British Columbia. In these harsh growing environments, partial cutting strongly influences the microclimate in terms of air and soil temperature, frost events, and snow-free dates. To examine the magnitude of this influence, three pairs of climate stations were set up in partial cuts and clearcuts, across a range of elevations, to compare microclimate conditions. The study also compared north edge, centre, and south edge microsites within one 30-m opening on each of three partial cuts.

Compendium of Forest Hydrology and Geomorphology in British Columbia by Robin G. Pike Pdf

Over the last two decades, hydrologists and geomorphologists have often discussed the need to document the history, scientific discoveries, and field expertise gained in watershed management in British Columbia. Several years ago, a group of watershed scientists from FORREX, academia, government, and the private sector gathered at the University of British Columbia to discuss the idea of a provincially relevant summary of hydrology, geomorphology, and watershed management. Through this meeting, the Compendium of Forest Hydrology and Geomorphology was born. As a synthesis document, the Compendium consolidates current scientific knowledge and operational experience into 19 chapters. To ensure reliable, relevant, and scientifically sound information, all chapters were extensively peer reviewed employing the standard double-blind protocol common to most scholarly journals. Chapters in the Compendium summarize the basic scientific information necessary to manage water resources in forested environments, explaining watershed processes and the effects of disturbances across different regions of the province. In short, the Compendium is about British Columbia and is primarily intended for a British Columbian audience, giving it a uniquely regional focus compared to other hydrology texts. At over 800 pages, the Compendium showcases the rich history of forest hydrology, geomorphology, and aquatic ecology research and practice in British Columbia and sets forth the foundation for the future by showing us how much more we have yet to learn.

Natural Regeneration of Small Patch Cuts in a Southern Interior ICH Forest by Jean Heineman,Jean Mather,Suzanne Simard,British Columbia. Forest Science Program Pdf

Almost all harvested sites in the interior cedar hemlock (ICH) zone of British Columbia are currently planted, but natural regeneration can be a viable reforestation alternative in small patch cuts or where a partial canopy is retained. This report describes a project in which five small, variable-sized patch cuts in an ICH forest were studied to determine the effects of opening size, edge characteristics, and substrate quality on the distribution & composition of natural regeneration. Results are presented & discussed regarding regeneration at four years after harvest.

Balancing Ecosystem Values by Anonim Pdf

Balancing Ecosystem Values: Innovative Experiments for Sustainable Forestry is a compendium of more than 40 contributions from Asia, Europe, and North America. The theme encompasses experiments implemented at an operational scale to test ecological, social, or economic responses to silvicultural treatments designed to balance the complex set of objectives currently targeted in sustainable forest management. Several invited and plenary papers emphasize the variety of outcomes demanded by the public, as well as the essential role that these long-term studies will play in allowing natural resource managers to make better-informed, science-based decisions. A broad spectrum of silvicultural treatments and systems are covered, as are simulation runs with different types of models and discussion about design challenges for scaling up from stands to landscapes. Diverse forest ecosystems, stand structures and plant, animal, and fungal species are also considered. The conference included 2 days in the field where participants saw several types of the comprehensive field experiments firsthand. The conference concluded with a critique from state, private, and public land managers.
