Measurement of plant moisture stress of 1-2 m understory conifers
was made in "reference stands" on the H. J. Andrews Experimental
Forest in 1970-1972. Maximum stress each year (measured between midnight
and dawn) is closely correlated with the position of each community
along one axis of an ordination of the...
Variation in nutrient content of forest trees is discussed using the
data from literature plus data collected by the authors. Sections are
included on sampling and methods of expression of nutrient content. The
emphasis is on possible causes of variation, which involves nutrient
variation between years, within the year, and...
The specific objectives of the program are: (1) To understand the relative behavior of terrestrial and aquatic ecosystems in various environments in the biome. (2) To develop conceptual and computer simulation models that describe nutrient, carbon, and waterflows on a short-term basis (fewer than ten years) and which integrate research...
This report describes decomposition studies conducted in the H. J. Andrews
Forest, Oregon in 1973. Changes in weight loss and nutrient content of
leaves, cones, branches, and bark of Douglas-fir and leaves of big-leaf
maple, vine maple, Rhododendron, red alder, sword fern Oregon oak, and
Chinkapin were recorded in a...
