- Description:
-
- Abstract:
-
This data set consists of a series of spreadsheets
containing annual sample plot measurments of
seedlings at study sites in the Oregon Coast
Range. Data will be collected from 1998 - 2004.
- Purpose:
-
The purpose of this study is to assess the effects
of density management on the growth and survival
of seedlings in the understory of young conifer
stands. This information will be used to develop
models to predict species growth following
thinning.

-
This study is being conducted at the Sand Creek,
Little Wolf, Blue Retro, and Perkins Creek density
management areas established by the BLM in the
Oregon Coast Range. In each stand the advanced
regeneration was released after a thinning that
occurred over 10 years ago. Recently, the study
areas were rethinned to 40-60 trees per acre
leaving an area of equal size as a control. All
stands have natural regeneration of primarily
Douglas-fir and western hemlock in the understory.
Three transects were installed in both the
rethinned area and the control. Transects were
spread throughout the area, but were in locations
with enough regeneration to get an adequate
sample. In each transect 100 trees were selected
and tagged. Trees were selected by establishing a
transect line and selecting the first 100 trees
within 7.5 meters of the transect line on both
sides. Trees that were overtopped by other trees
were not chosen. The length of the transect line
was dependent upon the amount of regeneration in
the area. Variables collected for each tree
included: species, basal diameter, diameter at
breast height, total height, height to live crown,
height growth, and logging damage. Little Wolf
and Sand Creek were measured in 1998, Blue Retro
in 1999, and Perkins Creek will be installed and
measured in 2000. Diameter and height growth
will be recorded at 2-year intervals for 4 years
or more. Growth rates will be related to initial
tree size, crown characteristics, and damage.
