Abstract

▷Collected seed from mature individuals of Thuja occidentalis at Trout Park and Chicago Junior School, as well as 3 control sites for comparison ▷Measured seed set, seed weight, and seed morphology to determine site variability ▷Conducted germination trials in growth chambers under incremental salt concentrations to determine the effect of salt on seed germination ▷Conducted periodic soil samples over the span of 1 year to assess salt levels at Trout Park and Chicago Junior School ▷Found differences between Trout Park and Chicago Junior School for reproductive metrics and soil salt levels, but not for germination
