Carbon and nitrogen dynamics associated with post-wildfire stand development of boreal mixed conifer ecosystems : application of data in model validation and refinement
(2006)Study site : Northwestern Ontario -
Carbon stock estimates for red spruce (Picea rubens) forest in central Nova Scotia
(2005)Carbon storage was measured in natural red spruce dominated stands in the Eastern Eco-region of central Nova Scotia (NS). Twenty-four plots over a 140-year chronosequence were established. Within each plot, major carbon ... -
Changes in soil nutrient status and seedling performance in response to harvest intensity on upland, shallow site types in Northwestern Ontario : 10th year results
(2007)Although based on limited empirical data, concerns have been raised that increased nutrient removals associated with full-tree harvesting on shallow-soiled sites may result in reduced productivity in subsequent rotations. ... -
Characterization, distribution and pathogenicity of bacteria isolated from chlorotic white spruce (Picea glauca (Moench) Voss)
(1981)Several genera of bacteria were isolated from the foliage, twigs, bark and wood of stems of chlorotic 10 - 12 years old white spruce (Picea glauca (Moench) Voss). Most of the isolates were nonspore-forming, aerobic ... -
Comparative analysis of alternative models of moose habitat carrying capacity
(1999)The focus of the project was to compare the performance of several alternative models in predicting the potential impacts of timber harvesting on a moose population northwest of Edmonton, Alberta, in terms of moose ... -
Comparative assessment of SFMM/Stanley & COMPLAN for forest management planning in Ontario
(2002)The growing complexity of forest management planning issues requires the best planning tools available. A key question facing forest management planners in Ontario is whether SFMM (and its harvest-blocking tool Stanley) ... -
Comparison of growth intercept and site index models of black spruce plantations and natural stands in Northern Ontario
(2008)Black spruce (Picea mariana Mill. B.S.P.) is one of the most important tree species in Canada, both ecologically and commercially. The forest industry has steadily increased efforts to artificially regenerate areas that ... -
Comparison of post-harvest sample designs to assess impact to organic forest soils in eastern Manitoba
(2001)Five sampling methods were developed, tested, and compared to assess soil impact from harvesting equipment on organic sites in unfrozen condition. This study pointed to the gap in the literature for such a sample design. ... -
Comparison of spatial vegetation patterns following clearcuts and fires in Ontario's boreal forests
(2000)The goal of this study was to compare spatial vegetation patterns, based on Landsat TM data, within post-clearcut and post-fire disturbances. Landscapes disturbed during the four decades prior to the collection date of ... -
Comparison of the pre-settlement and present diversity of the forests of Central Ontario
(2000)Original Crown Survey notes were used to infer the European pre-settlement forest diversity condition in the management units of Algonquin Park, French-Severn, Nipissing and Temagami in central Ontario, Canada. This ... -
Competition trials of Pinus banksiana and Populus tremuloides under a range of proportions and densities
(1986)This study was the -first study designed specifically to analyse the competitive effects of density and species mixture for both Pinus banksiana and Populus tremuloides seedlings during the initial stages of growth and ... -
Concepts, theories and models of succession in the boreal forest of Central Canada
(2009)Predicting plant community compositional responses to changing environmental conditions and disturbances is a key element of forecasting and managing for the effects of global climate change. With advances in ecological ... -
Conditioning white spruce (Picea glauca (Moench) Voss) transplants for overwinter storage by root pruning and wrenching
(1987)Problems associated with the establishment and early growth of outplanted white spruce (Picea glauca (Moench) Voss) led to research on conditioning white spruce transplants for overwinter frozen storage by root pruning and ... -
Crown dynamics in Pinus resinosa Ait. : analysis and stochastic description of branch production, branch extension growth and foliage dry weight---branch length relationships
(1981)The development of the crown structure of Pinus resinosa Ait. was analysed in terms of three component processes of tree growth: the number of first order branches per whorl within the crown, the annual extension increments ... -
Cytological studies of Inonotus tomentosus
(1988)Cytological studies revealed irregularities in the nuclear life cycle of Inonotus tomentosus. The mycelia was multinucleate and the nuclei were found in groups of two to six. By the time the nuclei reached the subhymenium ... -
Detection and assessment of Armillaria in young conifer plantations of northwestern Ontario and northeastern China
(1991)Methods for detecting and evaluating Armillaria in plantations were compared in a series of studies. The purposes of the studies were to standardize the Armillaria trapping technique, and to determine if it could be used ... -
Developing and testing the applicability of a decision support system for the planning of juvenile jack pine thinning
(1994)An investigation was made into the applicability of a model used to assist in planning the allocation of pre-commercial thinning to juvenile jack pine stands. The hypothesis of this study was that planning pre-commercial ... -
Development of a methodology for monitoring changes in Ghanaian forest reserves
(2000)The Ghanaian Forests are a significant component of the country’s development. Occasioned by the rapid population growth of the country, increasing phenomena such as shifting agriculture, logging, fuelwood harvesting and ... -
Development of optimal breeding zones for white spruce in Ontario under current, past, and anticipated future climate change / by Ashley Marie Thomson.
(2008)Tree breeding zones are delimited areas where trees are selected and bred, and their progeny are planted. Within these zones, the level of adaptation between seedlings and planting sites is controlled to ensure adequate ... -
Ecological effects of several reforestation and rehabilitation treatments on abandoned shifting cultivation sites in Sarawak, East Malaysia
(1994)The biomass, nutrient contents and soils of a chronosequence, including undisturbed primary forest (UPF), logged over forest (LOF), cleared and burned forest (for cultivation), abandoned cultivation sites, and four ...
