This report describes modern alpine vegetation of Fort Richardson and compares it to the paleontological record. The history of biotic response to environmental change during the postglacial period was constructed using fossil pollen from a peat profile in the Infantry Flats region. Modern pollen and insects were collected to provide modern baseline data for interpretation of fossil assemblages.
Describes the purpose and need for transformation of the 172nd Infantry Brigade (Separate) at Fort Wainwright and Fort Richardson, Alaska, into a Stryker Brigade Combat Team, decision to be made, comparison of alternatives, environmental consequences, and issues of concern.
Remote sensing and GIS were used to detect, measure, and monitor land cover changes for natural resources management purposes at Joint Base Elmendorf-Richardson, which was formed by the merger in 2010 of Elmendorf Air Force Base and Fort Richardson. The classification of vegetation in 2012 was validated through hundreds of site visits in 2013 and 2014. The report describes changes after various levels of intensity of human activity, climate changes, and expansion of spruce forest.
This report is similar to a Revised Uniform Summary of Surface Weather Observations (RUSSWO) except the summary generated is from data observed at limited-duty observation sites. This summary is blocked based on the normal hours of observation and only those tables using hourly data are presented. Caution must be exercised when using these summaries as the data reflect conditions occurring only during limited duty hours of operation. This report is a five-part statistical summary of surface weather observations for Fort Richardson, Alaska. It contains the following parts: (A)Weather conditions; (C) Surface winds; (D) Ceiling versus visibility; (E) Psychrometric summaries (psychrometric summary of wet-bulb temperature depression versus dry-bulb temperature, means and standard deviations of dry-bulb, wet-bulb and dew point temperatures and relative humidity); and (F) Pressure summary (means, standard deviations and observation counts of station and/or sea-level pressure). Summaries in this report are presented in tabular form, in most cases in percentage frequency of occurrence or cumulative percentage frequency of occurrence tables.
A six-part statistical data summary of surface weather observations for: FT Richardson AK. Summary consists of: PART A, Weather Conditions and Atmospheric Phenomena; PART B, Precipitation; PART C, Surface Winds; PART D, Ceiling and Visibility; PART E, Psychrometric Summaries; PART F, Pressure Summaries. See USAFETAC/TN-83/001 (AD-A123186), An Aid for Using the Revised Uniform Summary of Surface Weather Observations (RUSSWOs) for complete descriptions of contents and instructions for use. (Author).
Describes a ranking system used to evaluate the potential invasiveness and impacts of 113 non-native plants to natural areas in Alaska. Species are ranked by a series of questions in four broad categories: ecosystem impacts, biological attributes, distribution, and control measures. Also included is a climate screening procedure to evaluate the potential for establishment in three ecogeographic regions of Alaska [Juneau, Fairbanks, Nome].
