Plants

A

All sites sampled had 1 transect that ran south to north, with the southern end sampled 5 m due west of the biogeochemical sampling point. If a second “habitat type”, as based on visual assessment of the botanist in the crew, was located within a 50 m radius of the first sampling point, a second transect was done in that habitat.

Transects

PT ST

The number in each plant column records the number of quarter-meter-squared quadrats in 5 (1-meter-squared) quadrats in which that species was found at any given site.The 5 (1-meter-squared) quadrats were distributed to the right and left every 2 m along the 10 m transect.If the plant was not present, the cell has a 0;if the plant was present in every quarter-meter-squared quadrat, the number in the cell is 20.

Exotics

In the 2005 R-EMAP sampling invasive exotic plant species were surveyed in two ways. The first survey was done on the helicopter fly-in to the GPS site and covered the general area of the site, while the second was a 360° site survey from the helicopter pontoons after landing and covered the immediate area of the site. In the aerial (A) helicopter survey we looked for the presence of six invasive exotic species (Casuarina spp., Lygodium microphyllum, Melaleuca quinquenervia, Neyraudia reynaudiana, Pennisetum purpureum and Schinus terebinthefolius), as well as the presence of cattail (Typha domingensis). In the survey from the helicopter floats (F) we recorded the presence of any exotic seen; the only additional exotic species observed from the floats was Salvinia minima. In both surveys we recorded the presence of species and quantified their abundance using categories for the number of individuals. The categories used were 0 (i.e., not present), 1 individual, 2 - 10 individuals, and > 10. We did not find Neyraudia reynaudiana at any site, so this species was not included in the database.

Aquatic

As part of the EPA‘s R-EMAP Phase III wet season sampling, 54 sites (designated by Olsen numbers/station numbers) spanning the Greater Everglades were sampled for aquatic fauna in November and December 2005. Densities of small fish and large macroinvertebrates were quanitifed using a standardized throw-trap methodology, and macroinvertebrate infauna were enumerated from periphyton cores and floc samples. Community compositions and wet weights were recorded for throw-trap samples, and fish and crayfish lengths were measured. Counts and community compositions were recorded for infauna and scaled according to substrate samples (g AFDM and/or mL of periphyton or floc). Finally, stable isotope analysis was conducted on a subset of the fauna. These data were then used to address questions about consumer densities, community structure, and food webs along hydrological (disturbance) and productivity gradients.

Three throw-traps replicates were deployed per station.
