Phenotypic variation in cone and needle characters of Pinus banksiana Lamb. (jack pine) in Northwestern Ontario
(1990)
To assess the patterns of phenotypic variation in cone and
needle characters of jack pine relative to spatial, climatic and
ecological data, collections were made from ten trees in each of 64
sites in northwestern ...
Feasibility of community forestry in northern Ontario : a socio-economic and biophysical evaluation framework
(1991)
Community forestry has become a much-discussed form of
forest land tenure and management in Northern Ontario. It

The competitive relationship between jack pine (Finns banksiana Lamb.) and trembling aspen (Populus tremuloides Michx.) was studied in an 8-year-old mixed stand in North Central Ontario, Canada. During the summer of 1984, ...
Approach to predict nutrient status and growth response of fertilized jack pine by foliar diagnosis
(1979)
A factorial experiment testing N, P and K fertilizers, and a
series of simpler, two-treatment (control and NPK) fertilizer trials
were established in a range of jack pine stands to determine the
application of a foliar ...
Vegetative and sexual phenology, reproductive dynamics and bud differentiation in a clonal seed orchard of white and black spruce
(1981)
To evaluate the importance of phenology and strobilus
production in a clonal seed orchard of white and black
spruce, 14 clones of each species represented by 4 ramets
each, were selected from the Mattawin seed orchard. ...
