Genetic variation of wood properties in tamarack (Larix laricina (Du Roi) K. Koch)
Genetic variation of tracheid length, specific gravity, latewood percentage, height growth, and ring width among and within four provenances of tamarack (Larix laricina (Du Roi) K. Koch) was investigated in a ten-year-old ...
Stem wood structure of four Ghanaian Khaya species
Four closely related Ghanaian Khaya woods were studied for differences in anatomical, chemical and physical properties to enable clear identification o f the species. The species were Khaya cmthotheca (Ka), Khaya ivorensis ...
Analysis of hierarchical characteristics of landscapes in Ontario : detecting emergent levels of organizaton
Hierarchy theory suggests that complex systems such as ecosystems will develop hierarchical structure that can be reflected in multiple emergent levels of organization in landscape patterning. Emergent levels of organization ...
Impact of alternative harvesting practices on the small mammal community in an Ontario boreal mixedwood forest
During the current project four studies were conducted to determine the effect of alternative silvicultural systems, and harvesting methods on the small mammal community of a boreal mixedwood forest in northern Ontario. ...
Plantation establishment following chemical site preparation with triclopyr and plantation release with triclopyr-glyphosate herbicide mixtures
Two field studies were conducted to evaluate the use of Release™ (triclopyr ester) for chemical site preparation and its use in mixture with glyphosate for jack pine (Pinus banksiana Lamb.) plantation release.
Natural decay resistance of some Ghanaian timbers and wood decay hazard potential for Ghana
The natural decay resistance of 30 Ghanaian wood species, the decay capacity of four wood decay fungi, the effect of test method on fungal decay ability, and the wood decay hazard potential in Ghana were determined. Five ...
Effects of roads and log hauling on woodland caribou use of a traditional wintering area near Armstrong, Ontario
Increasing concern for the viability of forest-dwelling woodland caribou (Rangifer tarandus caribou) in Ontario has resulted in recommendations for more restrictive timber harvesting practices. Caribou populations have ...
Silviculture, growth and yield of neem (Azadirachta indica A. Juss.) plantations in northern Ghana
The silviculture and growth and yield of neem (Azadirachta indica A. Juss.) grown in individual and community plantations in the Tamale Forest District of Northern Ghana was investigated in 1995. Owing to rising populations ...
Vegetation response to harvesting, harvesting and prescribed-burning and wildfire in Northwestern Ontario : patterns of reproductive strategies and nutrient accumulation
Initial species composition was investigated on a group of boreal mixedwood sites that had experienced various forms of disturbance. The hypothesis explored was that environmental changes caused by different disturbances ...
Growth and yield of teak (Tectona grandis Linn F.) plantations in Northern Ghana
Teak (Tectona grandis Linn F.) is a popular exotic species in Ghana, widely grown in industrial plantations and small scale community woodlots. In spite of its importance, limited information exists on the growth and ...
