|a Coastal ecosystems lie at the forefront of sea level rise. We posit that
before the onset of actual inundation, sea level rise will influence the species
composition of coastal hardwood hammocks and buttonwood (Conocarpus erectus
L.) forests of the Everglades National Park based on tolerance to drought and
salinity. Precipitation is the major water source in coastal hammocks and is stored
in the soil vadose zone, but vadose water will diminish with the rising water table
as a consequence of sea level rise, thereby subjecting plants to salt water stress. A
model is used to demonstrate that the constraining effect of salinity on transpiration
limits the distribution of freshwater-dependent communities. Field data collected
in hardwood hammocks and coastal buttonwood forests over 11 years show that
halophytes have replaced glycophytes. We establish that sea level rise threatens 21
rare coastal species in Everglades National Park and estimate the relative risk to each species using basic life history and population traits. We review salinity conditions in
the estuarine region over 1999–2009 and associate wide variability in the extent of the
annual seawater intrusion to variation in freshwater inflows and precipitation. We
also examine species composition in coastal and inland hammocks in connection with
distance from the coast, depth to water table, and groundwater salinity. Though this
study focuses on coastal forests and rare species of South Florida, it has implications
for coastal forests threatened by saltwater intrusion across the globe. |
