Flora of temporary sand ponds in cass and Mason Counties, Illinois

Abstract

Seventy-two vascular plant species were collected from five temporary sand ponds located on mtensively farmed agricultural land in Cass and Mason Counties, Illinois, including 43 wetland obligate (OBL), 13 facultative wetland (FACW), 8 facultative (FAC), 5 facultative upland (FACU), and 3 upland (UPL) species. Of these, Scirpus hallii A. Gray, Scirpus purshianus Fern., and Boltonia decurrens (Torr. & Gray) Wood are endangered in Illinois. These ponds are farmed in dry years, but retain water during years of above average precipitation, such as 1974 and 1993. The continued reemergence of these plants during wet years suggests the persistence of seeds of these species within the soil seed bank.
