Résumé :	We studied wetland habitat use by wintering geese in the Coastal Plains and Rice Prairie Regions of Texas during 1991-92 and 1992-93. White-fronted Geese were most abundant on lacustrine littoral aquatic-bed floating vascular (x=2.10/ha) and unconsolidated shore organic (x = 1.55/ha) wetlands. White geese (Snow and Ross') were most abundant on estuarine intertidal aquatic-bed algal (x = 8.7/ha) wetlands. Canada Geese were most abundant on lacustrine littoral unconsolidated shore vegetated (x = 1.81/ha) wetlands. Geese used 16 of the 82 wetland types in the study area. Management of both open-water and vegetated wetlands is necessary to effectively influence the distribution and abundance of wintering geese.
