Samples taken at Cedar Creek, Minnesota, showed that the above-ground parts of cattail [Typha angustifolia] and maize ecosystems contained much the same low % of Sr90 as those of pastures in the area. Trees of the Oakwood ecosystem, however, contained much more Sr90 than the living plants of the other ecosystems. Unlike the crops and pastures, the woodland is likely to contain most of the Sr90 in the organic matter (other than the leaves) and relatively little in the mineral soil.
