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. ...
Foliage and wood production in 17- and 32- year old Pinus banksiana Lamb. of Northwestern Ontario
(1980)
The objectives of this study were 1) to provide information on
the above ground biomass production of young jack pine (Pinus banksiana
Lamb.) stands, and 2) to evaluate the influence of crown foliage stand
density, and ...
Applying criteria and indicators to assess ecological integrity of a boreal national park and adjoining forest management units / by Andrew James Promaine.
(1999)
Assessing and evaluating ecological integrity is a complex and often subjective task. However, recent legislative changes have forced ecosystem managers to develop more
quantitative techniques to measure ecological ...
Morphological variation in subalpine fir and its relationship to balsam fir in western Canada and the United States
(1988)
To help clarify the taxonomy of the two closely related North American firs
subalpine fir {Abies lasiocarpa (Hook.) Nutt.) and balsam fir {Abies balsamea
(L.) Mill.) in western Canada and the United States, 10 populations ...
Genetic variation in growth and yield components of juvenile balsam poplar (Populus balsamifera L.) growing in northwestern Ontario / by Frank Schnekenburger
(1988)
A nursery and greenhouse study of balsam poplar (Populus
balsamifera L.) were carried out in Thunder Bay, Ontario, to
study the extent and nature of variation in growth and its
relation to the following yield components: ...
Soil-site relations for jack pine in the Thunder Bay area
(1986)
Site index of natural jack pine (Pinus banksiana Lamb.) in the Thunder Bay area was related to features of soil and topography using multiple regression analyses. Site index (SI, height of jack pine trees at 50 years from ...
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 ...
Natural regeneration of black spruce (Picea mariana (Mill) B.S.P.) on lowland clearcut strips near Shebandowan, Ontario
(1989)
Growing conditions for black spruce natural regeneration on clearcut strips were
studied near Shebandowan, Ontario. These conditions were significantly different from
those present in the mature, residual forest in the ...
