This study has been concerned with the patterns of vegetative changes which occur during the first five years following logging and burning on Douglas-fir clear cuts. Knowledge of the successional sequence in the coastal forests of western Oregon is of primary importance to those concerned with the management of this...
Montane forest vegetation as it occurs on the east flank of the
central Oregon Cascades has provided excellent conditions for a
"natural experiment" in the use of various methodologies in studying
vegetational distribution. This "experiment" has reflected on some
theory and practice for the discipline of plant synecology. Detailed
descriptions,...
At the time of the eruptions of Lassen Peak in 1914-1915, an
area of vegetation along the east slope of the mountain approximately
1 1/4 miles wide and four miles long was destroyed. Except for a
few surviving trees, all vegetation was destroyed.
A study of the revegetation of this...
A study was undertaken in the Marys Peak watershed with the
following objectives. First, a classification of the major plant communities
was carried out. Second, some of the ecological features
of Acer circinatum that account for its distribution within these
communities were determined. The following plant communities
are described:
Corylus...
Fire has played a prominent role in the development and character of the ponderosa pine forests in western North American. Its
records are written in the scars of trees that have survived the fire.
Careful studies of these fire-scars may be used as a means of reconstructing
the fire history...
Twelve sites of uniform topography and soils were selected in
the Pinus ponderosa/Purshia tridentata/Festuca idahoensis Association.
These sites were located in the rain shadow on the east flank
of the Oregon Cascades. A fire history in the form of fire scars on
ponderosa pine was available for nine of these...
