  Citation × Citation Citation Abstract Copy Title: Identification and characterization of forest communities and habitat types in and adjacent to the H. J. Andrews Experimental Forest Author: Zobel, Donald B., U.S. International Biological Program. Coniferous Forest Biome, Dyrness, C. T., University of Washington, Franklin, Jerry F. A total of 23 forest communities have been identified and characterized in a preliminary manner. Data used in formulating the classification had previously been collected on 300 reconnaissance plots located on the H. J. Andrews Forest and surrounding area. Vegetation classification was facilitated by similarity analysis and stand ordination procedures developed by Dr. Will Moir, formerly of Colorado State University. Results of stand ordination indicate the presence of strong moisture and temperature gradients along which forest stands array themselves.

• 2. [Article] H.J. Andrews Experimental Forest reference stand system : establishment and use history

  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 ...

  Citation × Citation Citation Abstract Copy Title: H.J. Andrews Experimental Forest reference stand system : establishment and use history Author: Hawk, Glenn M., U.S. International Biological Program. Coniferous Forest Biome 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 around the natural stratification of vegetation provided by the differing habitat types. Several studies have tested theory about certain plant community-environment relations and given credence to the classification of habitat types in use in many northwest forests. This work reviews the methods for establishment, mapping, and collection of data on vegetation and the six-year history of use of the reference stands for 1972-1977. Title: H.J.

Coniferous Forest Biome, Dyrness, C. T., University of Washington 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 background ecological information about these watersheds, which then would be available before intensive studies were undertaken. This report contains a summary of the information obtained as a result of an inventory of vegetation and soils present on the watershed. It contains the vegetation mapping legend, vegetation maps, descriptions of mapped vegetation units, a generalized soil map, and a brief description of soils present. In addition to the small maps included with this report, large-scale vegetation maps (scale 1 in. = 2 chains: 1 chain = 66 feet) also are available.
