Coniferous Forest Biome<br/><br/>Abstract: The executive program and operating syntax of the forest growth model SUCSIM IV are outlined in Section A. Lists of parameters,state variables and other quantities, and their values (if constant) are given in Section B. The remainder of the bulletin is devoted to the models used. The quantities given here reflect the state of SUCSIM IV as of summer 1978. The readers are referred to published literature for examples of SUCSIM output. Careful comparison between the text and the program code has been made, but errors (typographical and otherwise) are inevitable in a work of this scope. The authors invite notification of any and all errors and inconsistencies. http://hdl.handle.net/1957/7580 Title: Riparian vegetation in Oregon's western Cascade Mountains : composition, biomass, and autumn phenology<br/><br/>Authors: Campbell, Alsie Gilbert; Franklin, Jerry F.; U.S. International Biological Program. Coniferous Forest Biome<br/><br/>Abstract: Sixteen understory plant communities in the riparian zones of small streams are identified and described. They range from pioneer communities on gravel and rock to well-developed shrub communities on floodplains and terraces. Several other vegetation types are discussed. Distribution of communities within the riparian zone is also discussed. A survey of nine small streams shows the Acer circinatum community tohave the widest distribution and highest cover, but the Rubus spectabilis/Ribes bracteosum community is somewhat more common in the active zone. Biomass estimates are made for riparian vegetation along three stream segments. Total foliar production for 1976 is calculated for all vegetation, for communities, and for individual species. The percentage of each type of foliage which may reach the stream directly, indirectly, ornot at all is estimated. Abscission and fall senescence for thirteen species was monitored. Leafy and herbaceous detrital input is timed. Rates of leaf fall anddecadence are related to environmental factors. http://hdl.handle.net/1957/7581 Title: Conifer : a model of carbon and water flow through a coniferous forest : revised documentation<br/><br/>Authors: Sollins, P.; Brown, Alfred T.; Swartzman, G. L. (Gordon L.); U.S. International Biological Program. Coniferous Forest Biome<br/><br/>Abstract: CONIFER simulates water, carbon, and energy dynamics of a coniferous forest. The model consists of 29 nonlinear difference equations. Measured driving variables include air temperature, dew point temperature, precipitation, solar radiation, and wind speed. Water and energy variables are updateddaily; carbon variables are updated weekly. This report contains a detailed description of the model including all equations, parameter values, and initial conditions. Cross-reference tables list the equations in which each variable and parameter appear. Listings of the driving variable data,computer implementation, and corresponding output are also provided. Information sources and model behavior are discussed elsewhere. http://hdl.handle.net/1957/7578 Title: H.J. Andrews Experimental Forest reference stand system : establishment and use history<br/><br/>Authors: Hawk, Glenn M.; U.S. International Biological Program. Coniferous Forest Biome<br/><br/>Abstract: Nineteen l/4-hectare reference stands have been established in the centralwestern Cascade Mountains of Oregon to represent widespread and importantportions of the vegetation continuum. Their species diversity, cover, andstructure are described here. The stands provide points of reference forvisiting scientists and researchers who wish to design experiments around thenatural stratification of vegetation provided by the differing habitat types.Several studies have tested theory about certain plant community-environmentrelations and given credence to the classification of habitat types in usein 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.
