To understand the pattern of adaptive variation of jack pine in north central Ontario better, short-term provenance tests were established. Seed was collected from 64 sites to the east and west of Lake Nipigon and grown ...

This study examined two topics. In the first, a computer algorithm was developed to process stem analysis data produced by Tree Ring Increment Measure (TRIM) system. The algorithm developed not only processed TRIM data ...

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 ...

To evaluate the hypothesis that current forest management practices in the boreal forest are decreasing the quantity and quality of long-term marten habitat, and alternative, more suitable strategies exist, a ...

Levels of public participation in the management of a community forest (CF) depend on the CF’s goals and the subsequent decision-making structure that the community adopts. To evaluate the hypothesis that the Ontario ...

If humankind is to cope with the cumulative effects of its expanding populations on the earth’s ecosystems, a new relationship is required with natural systems. Serious adoption of the concepts of forest sustainability ...

Alley cropping is a crop production system in which food crops are grown in the alleys created by hedgerows of selected tree species, preferably legumes. The objective of this study was to model a Cassia /maize alley ...

Competition in forestry is discussed as a prelude to the hypothesis that tree seedling growth is strongly related to that of other vegetation close to it. The hypothesis states that: a) the relationship is species-dependent; ...

An investigation was made into the rates of moisture content, extractives and basic wood density losses that occur when trembling aspen (Populus tremuloides Michx.) wood chips are stored during different seasons ...

Genetic variation In traits potentially affecting the waterrelations of balsam poplar (PopuIus balsamifera L.) clones from four provenances along a transect from northern Wisconsin to Pickle Lake in northwestern Ontario ...
