Historic landcover dynamics in a scrubby flatwoods (Tel-4) and scrub landscape (Happy Creek) on John F. Kennedy Space Center were measured using aerial images from 1943, 1951, 1958, 1969, 1979, and 1989. Landcover categories were mapped, digitized, geometrically registered, and overlaid in ARC/INFO. Both study sites have been influenced by various land use(More)
Fire has historically been an important ecological factor maintaining southeastern U.S. vegetation. Humans have altered natural fire regimes by fragmenting fuels, introducing exotic species, and suppressing fires. Little is known about how these alterations specifically affect spatial fire extent and pattern. We applied historic (1920 and 1943) and current(More)
Fires occur naturally in many wetlands and are widely used for marsh management. We examined the responses to fire ofJuncus roemerianus andSpartina bakeri marshes on Kennedy Space Center, Florida. In each marsh, we determined vegetation cover before burning on 5 permanent 15 m transects in the greater than 0.5 m and less than 0.5 m layers and sampled(More)
Co-occurring species may have differing growth responses to the seasonal timing of climatic events. In this study, we used dendrochronology to examine the importance of seasonal climate on radial stem growth of three co-occurring species in Florida scrub, myrtle oak (Quercus myrtifolia Willd.), Chapman oak (Quercus chapmanii Sarg.), and south Florida slash(More)

We examined soil changes in the 0–5 and 5–15 cm layers for one year after a fire in burnedJuncus roemerianus andSpartina bakeri marshes and an unburnedJuncus marsh. Each marsh was sampled (N=25) preburn, immediately postburn, and 1, 3, 6, 9, and 12 months postburn. All marshes were flooded at the time of the fire; water levels declined below the surface by(More)
