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 ...
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 ...
Establishment and early growth of jack pine (Pinus banksiana Lamb.) in Acton Township Ontario
(1986)
The objective of this study was to investigate the effect of different site
preparation methods on the establishment and growth of jack pine (Pinus banksiana Lamb.) on two different soil types. These sites were either ...
Estimating site quality from early height growth of white spruce and red pine plantations in the Thunder Bay area
(1986)
Growth intercepts and breast height-age height growth curves were developed for estimating the site quality using early height growth in white spruce {Picea glauca (Moench) Voss) and red pine (Pinus resinosa Ait.) plantations ...
Genetic and environmental variation in seed, cone and progeny characteristics of black spruce clones in a northern Ontario seed orchard
(1985)
Genetic and environmental variance in cone and seed
properties and early progeny growth of Picea mariana (Mill.)
B.S.P. clones were evaluated using cones and seed from two to
three ramets of 19 clones each growing in a ...
Integrated resource management planning through the linking of mathematical and judgement-based models
(1988)
The objective of this study was to develop an
analytical technique to enable forest managers to handle
effectively the complex problem of integrated resource
management planning using quantitative and qualitative
information. ...
Effects of container volume and shape on the growth of black spruce (Picea mariana (Mill.) B.S.P.) seedlings
(1984)
The objective of this thesis was to evaluate the growth of black spruce seedlings in containers with four soil volumes (45, 90, 180, 360 cm3) and at three diameter/depth shapes (1:2, 1:3, 1:4). Seedling height, root collar ...
Winter use of upland conifer alternate strip cuts and clearcuts by moose in the Thunder Bay District
(1988)
Moose (Alces alces) utilization o£ five paired strip cut -
clearcut areas was studied during the winters of 1983 - 84 and
1984 - 85. Winter aerial reconnaissance flight data were
supplemented by snow condition observations ...
Evaluation of a mini-container accelerated transplant system : the black spruce winter crop
(1986)
The effects of four factors on nine attributes of black
spruce (Picea mariana (Mill) B. S. P.) seedlings were
investigated. The seedlings were produced under an
accelerated transplant system that used a 6 ml Castle ...
