  Citation × Citation Citation Abstract Copy Title: Vegetation and stem mapping of watershed 10, H. J. Andrews Experimental Forest Author: Hawk, Glenn M., U.S. International Biological Program. Coniferous Forest Biome, University of Washington 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. Descriptions of these communities based on field notes and extrapolation from reference stands located in the Andrews Experimental Forest are included along with structural characteristics of the communities and habitat types. Size class distributions of living trees greater than 15 cm dbh are also included for the whole watershed, for communities, and for habitat types. INTRODUCTION: Watershed 10 has been selected for current modeling efforts of the IBP Coniferous Forest Biome project at the Oregon intensive study site, H. J. Andrews Experimental Forest. This report supplies a necessary input for calculating standing crop of vegetation in all strata from trees to mosses. A community description approach has been used with tables and appendices furnishing data concerning trees, shrubs, herbs and mosses occurring within the watershed. Watershed 10 contains representatives of communities common to the lower elevation regions of the Tsuga hetero h lla Zone of Franklin and Dyrness (1969). Within watershed communities are identified, which are discussed below. Major emphasis of this report is placed on description of the vegetation. Some comparisons of communities with each other and with other portions of the Tsuga heterophylla Zone near the H. J. Andrews Experimental Forest are also included. Watershed 10 is a 10.24 hectare watershed that drains to the west. It is located near to but outside of the southwestern boundary of the Experimental Forest. The elevation of the watershed ranges from 1425 feet (435 m) to 2,275 feet (695 m). The entire watershed lies within the Tsuga heterophylla.Zone of Franklin and Dyrness. METHODS: Preliminary surveying of watershed 10 with staff compass, chains and Abney levels was completed in 1970. During this surveying three base lines running north and south were established at equal intervals within the watershed. These base lines served as reference points during the establishment of a 25 m grid system in 1971-1972. Using staff compass, chains, and Abney levels, the 25 m grid system was established with correction for slope over the entire watershed (figure 1). During spring, 1972, aluminum corner stakes were installed and labeled to mark the 25 meter grid corners. Grid sections were numbered, for referencing positions in the watershed.

  Citation × Citation Citation Abstract Copy Title: Modeling the hydrological aspects of the Fern Lake Watershed : annual report 1971 Author: U.S. International Biological Program. Coniferous Forest Biome, Fowler, Charles W. (Charles Winsor), 1941-, University of Washington Data collected from the Fern Lake watershed between 1958 and 1971 include measurements of the rate of flow of water into the lake through a single inlet stream. The objective of the work presented here is to develop a model of this flow using the climatological data available from the watershed. Measurements of air temperature, wind movement, air pressure, relative humidity, insolation, and precipitation were used to estimate the potential evapotranspiration through the use of the Penman equation (Penman 1948). A model based on relationships found in the published literature and some empirical relationships was developed to simulate the dynamics of the soil water. This submodel was incorporated into the larger model to link the climatological input variables to streamflow. Output from the computer program developed for the model includes soil water content, underground flow, evaporation, transpiration, and streamflow. In its tentative form, the model is sufficiently realistic to be used for further modeling of the dynamics of other aspects of the watershed involving water flow.

  Citation × Citation Citation Abstract Copy Title: Fleshy fungi fruiting in the H. J. Andrews Experimental Forest : a partial list of collections from fall 1970 to spring 1972 Author: U.S. International Biological Program. Coniferous Forest Biome, Rhoades, Frederick Mast, University of Washington 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. Collections were made from October, 1970 to April, 1972; generally, the more fungi fruiting, the more often trips to collect were made. Attempts were made to culture all fungi from fresh and large enough specimens, though only few positive cultures were obtained. Specimens were dried and deposited in the OSU herbarium. In addition, those collections of Dr. James Trappe and Robert Fogel, made from the Andrews, are included in the list. I would like to aknowledge the help of Dr. D. E. Stuntz and Dr. Alexander Smith in identification of some collections. Needless to say this list is hardly complete; it is presented with the expectation that changes, additions and deletions will be sent to the author, by those who know the fungal flora and have made collections in the Andrews and nearby.
