Table S2 Importance value, relative abundance [%] and frequency of occurrence for species [%] sampled in sedge meadow (N=60), Blechnum-Cladium parkland (N=44) and woody hammock (N=58) habitat in the savanna of Utila, Bay Islands, Honduras, 2011. Bold faced values show the cover value for characteristic species of each habitat, but the table is cross-tabulated to show species abundance in the other habitats. * indicates species generally associated with the tops of mounds not undergoing diel inundation.
