Abstract
The 87Sr/86Sr range of vegetation for the study area is 0.7081-0.7130. Soil and streamwater samples collected at proximal locations to the vegetation demonstrated a range of 0.7086-0.7133 for soil leachates and 0.7081 to 0.7107 for streamwaters. Statistically significant (pâ¯<â¯.05) differences between the spatial distribution of 87Sr/86Sr in plants and certain underlying bedrock/Quaternary sediment were identified, even in a region without an extreme range in 87Sr/86Sr values. Careful selection of appropriate soil leaching protocols is necessary for an informative estimate of the natural ranges that exist within the pedosphere, supporting the notion that plant material is the most suitable sample medium for mapping bioavailable Sr. The high degree of spatial variability in 87Sr/86Sr and differences between reservoirs can only be accurately represented by relatively high-density sampling of plants. These data complement both national and European-wide initiatives to produce large-scale 87Sr/86Sr biosphere maps.
