Seed Yields of Four Moist-soil Plants on Noxubee National Wildlife Refuge

Emphasis on use of moist-soil management for waterfowl has increased in recent years. One component of this form of management which is not well documented are seed yields of many native plants produced. Seed yields of 4 moistsoil plant species were measured during the growing season of 1985 and 1986 on the Noxubee National Wildlife Refuge in Mississippi. Seed yields of 3 species, Polygonum hydropiperoides (Michaux), Polygonum densiflorum (Meissner), and Rhyncospora corniculata (Gray), were measured using a specially designed seed trap. The fourth species, Ludwigia glandulosa (Walter), was...
