Abstract

Managers mow, disk, and till moist-soil habitats to set back succession and increase interspersion of emergent vegetation and water for migrant and wintering waterbirds. We evaluated effects of autumn applications of these manipulations on aquatic invertebrates and moist-soil plants during 2 subsequent winters and growing seasons, respectively, at Noxubee National Wildlife Refuge, Mississippi. Greatest seed mass was in tilled and disked plots in1993 (P less than or equal to 0.008) and in tilled plots in 1994 (P less than or equal to 0.008). Plant species diversity generally was greatest in tilled plots in both years (P less than or equal to 0.05). Mowed and controlplots produced greatest aquatic invertebrate mass in winter 1992-93 (P less than or equal to 0.025) and diversity in both winters (P less than or equal to 0.01). invertebrate mass and plant standing crop generally did not differ among treatments in winter 1993-94 and both years, respectively. We recommend autumn tilling in small moist-soil habitats to increase plant species diversity and seed yield. For large-scale management, disking may be more practical than tilling and would likely yield similar plant responses. Werecommend autumn mowing if moist-soil habitats exist in early seral stagesand contain desirable seed-producing plants that are robust and do not readily topple following flooding to create open water areas for waterbirds.
