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...
Studies in the lower Lookout Creek-Blue River area have revealed a geomorphic history including glaciation and the development of three alluvial surfaces, presently active alluvial cones and older, deeply dissected cone remnants. Results are based on landform mapping, analysis of the types and distributions of surficial sediments, and the
distribution...
The fleshy carpophores of fungi fruiling, on soil and litter were collected from watersheds 2, 3, and 10, IBP sites located in the H.J. Andrews Experimental Forest near Blue River, Oregon (122° W, 44° N). No effort was made to systematize collections: all
carpophores in fresh condition seen were taken....
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.
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...
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...
Stem mapping of all trees greater than 15 cm dbh has
been completed on the 10.24 hectare watershed (No. 10) at H. J.
Andrews intensive study site. Using a 25 m grid system, mapping
of vegetation into 7 plant communities and then into 4 habitat
types has also been completed....
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...
