Work within the vegetation management
research program concentrated on two
projects:
-
Enhancing Douglas-fir seedling
growth on a dry salal-dominated
site
This cooperative project, established
in 1998 with Malaspina College,
is evaluating and demonstrating
disc trenching and seedling fertilization
for enhancing Douglas-fir growth
on a dry salal-dominated site. The
project builds on the research initiated
in the mid-1980's which demonstrated
potentially large increases in Douglas-fir
growth through reductions in salal
abundance and through nutritional
supplements.
-
Response of non-crop vegetation
to manual cutting and glyphosate
and subsequent Douglas-fir growth
in the coast-interior transition
- E.P. 1037
This study was initiated in the
late 1980's on three sites in the
Coast Region to evaluate manual
cutting as a vegetation management
tool for releasing conifers. To
determine the effect of timing on
efficacy, manual cutting treatments
ranging from early to late in the
growing season. Glyphosate was also
tested as a herbicide alternative
to the manual treatments. Squamish
District funded the 10th year remeasurement
of the site within coast-interior
transition. Reporting is currently
underway.
Additional information and district
specific lists of project sites can
also be obtained at the Research Branch
Forest Dynamics web site. Research
by the Forest Dynamics Group concentrates
on factors which influence regeneration,
survival, and growth of young forests.
