“…Although hydroperiods have been defined in various ways (Ross et al 2003;Childers et al 2006;Givnish et al 2008;Zweig and Kitchens 2008;Todd et al 2010;LoGalbo et al 2013), they are usually calculated as annual means. In our study, use of environmentally-defined hydroperiods (the hydrologic interval) enlarged the hydrological description by allowing the length of the wet or dry event to extend over several years when appropriate.…”

“…Combining such hydrologic datasets with landscape-level community information, we now can quantify in situ hydrologic regimes of plant communities across large spatial extents. This quantification is important, as wetland restoration targets often associate restoration of a particular community with restoration of a particular hydrologic regime (McVoy et al 2011;LoGalbo et al 2013), but this association is not based on quantification of the full range of biotic and abiotic conditions in the landscape. Having large-extent datasets that cover different landscape units allows analysis of vegetation/hydrology relations of sub-regions that differ in hydrology or hydrological management.…”

Large-extent vegetation datasets that co-occur with long-term hydrology data provide new ways to develop biologically meaningful hydrologic variables and to determine plant community responses to hydrology. We analyzed the suitability of different hydrological variables to predict vegetation in two water conservation areas (WCAs) in the Florida Everglades, USA, and developed metrics to define realized hydrologic optima and tolerances.Using vegetation data spatially co-located with long-term hydrological records, we evaluated 7 variables describing water depth, hydroperiod length, and number of wet/dry events; each variable was tested for 2-, 4-and 10-year intervals for Julian annual averages and environmentally-defined hydrologic intervals. Maximum length and maximum water depth during the wet period calculated for environmentally-defined hydrologic intervals over a 4-year period were the best predictors of vegetation type. Proportional abundance of vegetation types along hydrological gradients indicated that communities had different realized optima and tolerances across WCAs. Although in both WCAs, the trees/shrubs class was on the drier/shallower end of hydrological gradients, while slough communities occupied the wetter/deeper end, the distribution of Cladium, Typha, wet prairie and Salix communities, which were intermediate for most hydrological variables, varied in proportional abundance along hydrologic gradients between WCAs, indicating that realized optima and tolerances are contextdependent.3

“…Restoration of this patterning is a major conservation goal. Ridges are dominated by the emergent Cladium jamaicense (sawgrass), whereas sloughs are characterized by the floating‐leaved Nymphaea odorata (white water lily) (McVoy et al, 2011; LoGalbo et al, 2013). The emergent Eleocharis cellulosa (spikerush) occurs in sloughs but is also a dominant component of the slightly shallower wet prairies and ridge–slough transitions (Givnish et al, 2008; Zweig and Kitchens, 2008; McCormick et al, 2009).…”

The effects of water depth and flow on marsh plant litter decomposition and soil chemistry were measured in the Loxahatchee Impoundment Landscape Assessment (LILA) facility (Boynton Beach, FL), where macrocosms mimic Everglades ridge-and-slough landscape features. Experiments were conducted in two macrocosms that differed in flow but had ridge, shallow slough, and deep slough habitats that differed in water depth. Decomposition of three common Everglades species, Crantz, Torr., and Aiton, were measured using litter bags incubated in the macrocosms under both wet and dry conditions. Litter decomposition was similar among flow treatments and habitats but differed by species and between wet and dry conditions. Decomposition rates from fastest to slowest were > > litter had more total P than the other two species, confirming the importance of P availability in controlling decomposition in the Everglades. Planted species had no effect on soil nutrient content during the ~4 yr of plant growth. Average water velocities of ~0.5 cm s attained in the flow treatment had no effect on decomposition or soil chemistry. The plant species used in this study are major contributors to Everglades' organic soils, so their decomposition rates can be used to parameterize models for how restoration manipulations will affect soil-building processes and to predict the temporal sequence of landscape responses to these manipulations. The results suggest that longer periods and flows greater than studied here may be necessary to see restoration effects on soil building processes.
