Altitudinal variations in upland regions of the earth create
variable climatic zones and conditions. Plant and animal
communities must adapt to these conditions, and when they reach
their tolerance limits for environmental conditions at the upper
levels of a zone, they cease to exist in the environment. Humans

The western Siskiyou Mountain forest vegetation
is grouped into eight communities based on parent
material. Three groups of data are analyzed using a computerized
ordination technique, two of the groups together,
and one separately. Two communities associated with
ultramafic parent materials, two on sandstone, one on
greenstone, and one on...
Stream channel stability for two tributaries of Rock Creek in the
Oregon Coast Range is evaluated by application of a Stream Reach Inventory.
Stability nomographs are constructed for graphical analysis of
erosion potential. Results indicate that channel stability can be
classified. One stream is rated as 'Poor' in resistance to...
The dramatic upsurge of contract-supported archaeological activity,
generated by legislative action, has precipitated an increase
in information about Oregon's prehistoric peoples. This information,
however, has not been presented in a format which can be easily
