Site quality evaluation of jack pine in Northern Ontario using site-index curves
(1994)
Jack pine stem analysis data from 383 fully stocked, mature, undisturbed
plots were collected from studies located in four Ontario Ministry of Natural
Resources regions (Northeast, Northern, North Central, Northwestern) ...
Developing and testing the applicability of a decision support system for the planning of juvenile jack pine thinning
(1994)
An investigation was made into the applicability of a model used to assist in
planning the allocation of pre-commercial thinning to juvenile jack pine stands. The
hypothesis of this study was that planning pre-commercial ...
Ground speed : its influence on the direct seeding of jack pine (Pinus banksiana Lamb.) with the Bracke scarifier
(1993)
The effects that ground speed and obstacle height have
upon microsite creation by the Bracke scarifier and upon the
seeding characteristics of the integral seeder were studied.
The study was conducted in a former gravel ...
Implications of alternative herbicide-use policies for forest management in Ontario
(1995)
Public sentiment is against herbicide use on public forests in Ontario. Provincial
policies are directing research into alternative vegetation management with only
limited interaction or support with forest resource based ...
Genetic variation in height and diameter of tamarack (Larix Laricina) and their correlation with syllepsis
(1997)
The broad sense heritability of total height, annual height increment, diameter, volume index
and syllepsis of II provenances of tamarack in northwestern Ontario were examined. Genetic and
Pearson Product Moment correlations ...
Spruce budworm (Choristoneura fumiferana Clem.) late-instar dispersal and impact on host-species natural regeneration in a boreal mixedwood forest of Ontario
(1996)
Understory feeding by the spruce budworm ( Choristoneura fumiferana
Clem.) has potential to alter the species composition of established regeneration
and therefore the value of the future forest. This study sets out to ...
Assessment of land cover changes and hydrologic response of Tamne River Basin
(1996)
Northeastern Ghana, West Africa, is characterised by a high population growth rate and adverse
climatic conditions, e.g., a long dry season followed by a short-duration but intense rainfall
pattern. Land degradation in ...
Participatory action research as a tool for community development : experiences from Northwestern Ghana
(1998)
This study reports on a community development project conducted in Charia, a small village
in northwestern Ghana. The primary intent of the study was to field-test the participatory action
research approach of actively ...
Effects of harvest treatments on spruce budworm, Choristoneura fumiferana (Clem.) (lepidoptera: Tortricidae), dispersal within forest stands
(1996)
Dispersal is a critical trait during the life history of
the spruce budworm, Choristoneura fumiferana (Clem.), which
leads to its widespread infestation and damage. Budworm
dispersal study is of importance for protecting ...
