Impacts of smelter emissions on vegetation communities -- The identification of causal mechanisms
- Hagler Bailly, Inc., Boulder, CO (United States)
Field measurements of vegetation community structure in an area of southwest Montana contaminated by arsenic and metals were combined with data from laboratory phytotoxicity studies and field soil sampling studies to identify the causal mechanisms responsible for modifications to the vegetation communities. Causal relationships between vegetation community modifications and continents were identified using two methodologies: Kendalltau correlations among soil contaminant concentrations, phytotoxicity scores, and vegetation community matrices; and a causality evaluation approach that included the identification and evaluation of all other stressors that could potentially have resulted in the observed vegetation impacts. It was concluded that the contaminants were important causal agents in the observed modifications to the vegetation communities.
