Natural Resource Damage Assessments


Statisticians with WEST are internationally known for their common sense application of statistics to solve natural resource problems. They specialize in practical, state-of-the-art design and analysis of field and laboratory studies.

WEST’s involvement in the Natural Resource Damage Assessment (NRDA) process generally comes in study design, study implementation and statistical analysis associated with assessing injury. WEST’s role as a leader in designing and implementing scientific studies of natural resources has proven to be an asset when working as part of a NRDA team.

We emphasize the use of valid sampling methods in order to attain scientifically sound conclusions that are representative of the area of interest. We have provided guidance in designing and analyzing results from long-term monitoring studies. After multiple research projects have been conducted WEST is exceptionally qualified to conduct meta-analyses and provide a synthesis of the analytical information that has been collected.

NRDA Experience

WEST’s NRDA work has involved large and small spill events. Most notably, WEST staff were involved in designing studies to evaluate impacts to wildlife after the Exxon Valdez Oil Spill in 1989. WEST has also played smaller roles in NRDA cases like the Blackbird Mine in Idaho where we worked with federal scientists to investigate fish mortality associated with mine tailings. More recently, WEST has worked to assess the injury from the 2010 Gulf Oil Spill on marine mammals, turtles, oysters and nearshore environments.
