Forty-nine genera and ninty-eight species of Lichenized fungi are reported from the H. J. Andrews Experimental Forest (Oregon). Substrates, growth form, and type of phycobiont are indicated for each taxon.
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...
Populations of mites and.nematodes were monitored on Watershed 10, H. J.
Andrews Forest. A minimum of 50 families and 60 genera of mites are
present, the majority being Cryptostgmata. Population estimates vary
from 5000-350,000 per square meter. Nine categories of nematodes are
present, most belonging to the saprozoic, dorylaimoid, aquatic...
Nineteen l/4-hectare reference stands have been established in the central western Cascade Mountains of Oregon to represent widespread and important portions of the vegetation continuum. Their species diversity, cover, and structure are described here. The stands provide points of reference for visiting scientists and researchers who wish to design experiments...
The arthropod community in a Douglas-fir forest near Blue River, Lane County, Oregon was investigated from March through August 1973. Five stands of Douglas-fir were sampled: two clearcuttings, a young-growth
(20 years old), a midgrowth (125 years old), and an old-growth (450 years old) plot. A pole pruner was used...
Field and laboratory studies are being conducted to describe the hydrologic properties of soil and to determine the timing pathway of precipitation and snowmelt water as it moved through forested soil on a steep slope. Hydrologic properties include hydraulic conductivity, porosity, pore-size distribution, moisture characteristics, stone content, and soil depth....
This report lists 98 microfungi found in the H. J. Andrews Experimental Forest, Lane County, Oregon, between June 1970 and
August 1972. The taxonomic treatments of the Ascomycetes and the Fungi Imperfecti in general follow Dennis (1968) and Barnett (1960), respectively. Specimens are deposited in the herbarium at Oregon State...
Early in the planning of the Coniferous Biome research program, it was recognized that Experimental Watersheds 6, 7, and 8 in the
H. J. Andrews Experimental Forest might provide ideal study sites for certain phases of the Biome program. A study was funded during year 1 (1970) to provide necessary...
Early in the planning of the Coniferous Biome program It was recognized that experimental watersheds 2 and 3 in the H. J. Andrews Experimental Forest might provide ideal study sites for certain phases of the Biome
program. A study was funded during year 1 (1970) to provide necessary background ecological...
