The vascular flora at Van Horn Woods Park was surveyed during the 1998-2000 growing seasons. This park is a 30 hectare site located in Plainfield Township, Will County, Illi- nois (SE1/4 S27 T36N R9E). A total of 246 taxa, representing 160 genera and 67 fami- lies, were identified within or immediately adjacent to the park. Seventy-one percent of these taxa were native. Four taxa were collected and submitted to the Morton Arboretum as new county records for Will County. The quality of this site as a natural area was also assessed using quantitative methods based on floral composition and diversity. The site was found to have a mean C value (C) of 3.44, a modal C value of 5, and a floristic quality index (I) rating of 45.51. These results indicate that Van Horn Woods is a site adequate enough in natural floristic quality to be worthy of protection and preservation.
