Overview
Monitoring and characterization under EMC involves collecting and analyzing the appropriate ecological data to assess potential impacts and detect population trends for key species. The work includes collection of population-level information for presence and abundance of biota for key habitat types, and collection and analysis of community and population-level data over longer time periods to detect changes in population sizes and condition. These data are used to assess relative resource values, determine presence or absence of organisms as risk receptors with respect to legacy contaminants in the environment, and to detect changes in populations that may or may not be related to Hanford operations.
- Rare Plants contains a map showing the location of rare plant populations on the Hanford Site
- Vegetation Surveys has the Hanford Site vegetation map, as well as information from recents surveys and fire maps
- Fish & Wildlife Surveys contains information from ongoing surveys
- Long-term Monitoring Plots contains survey results for the Biological Resource Monitoring Plots (BRMaP)
- Historical Surveys contains information for long-term surveys of Canada geese nesting (1953-2001), wintering bald eagles (1961-2001), shrub-steppe bird surveys (1988-2005), elk (1975-2001), and hawk nesting (1973-2005)
Summary information is published annually in the
Hanford Site Environmental Report
