Disturbance profiles, indices based on both spatial and non-spatial
statistics, are used to examine how small-scale disturbances and
the resulting canopy gaps disrupt ecosystem patterns and processes
in selected stands in the Blue Mountains of Oregon. The biological
meaning of many indices remains undefined for small scale disturbance
phenomena, but their disturbance profiles could eventually be used
to assess current and desired forest conditions and suggest actions
to meet specific management objectives. These profiles can be determined
for plots representing desired conditions associated with specific
management objectives, to establish a range of variability for forest
health indicators, and to monitor the progress of disturbances used
as silvicultural tools.
