The goal of this project was to examine the co-variation in macrophyte and microbial mat biomass along the hydrologic gradient present across wetland regions and to determine the type and strength of interactions occurring between the two communities, which was tested using a biomass (macrophyte or microbial mat) removal experiment. The census observational survey took place at 140 sites from 2003-04-09 to 2004-05-26, which were randomly distributed across the hydrologic gradient present across the six temporary wetland regions. The transect observational survey occurred along six transects and each was deliberately established along the present hydrologic gradient within each region; a total of 254 sites were sampled from 2003-02-19 to 2005-03-04. The experiment took place at three temporary wetland sites with contrasting hydroperiods (3 – 6 months), and four transects were established per site with 24 pairs of control and treatment plots per transect. The removal treatment occurred one year before data collection, and data collection occurred from 2004-06-20 to 2006-11-25. The package includes six datasets, one R code file, and two shape files associated with the R code. Data collection for all datasets is complete. FCE1274_Census_Survey includes hydrologically-regulated macrophyte community type classifications, macrophyte biomass, microbial mat ash-free dry mass, mean soil depth, water depth, mean annual hydroperiod, and vegetation-inferred hydroperiod; each site was sampled once during the survey period and a subset of sites were sampled each year. FCE1274_Transect_Survey includes macrophyte community type classifications, macrophyte biomass, microbial mat ash-free dry mass, mean soil depth, water depth, mean annual hydroperiod, and vegetation-inferred hydroperiod. Each site was sampled once during the survey period; all sites along each transect were sampled before moving to the next transect. FCE1274_Removal_Experiment includes total macrophyte biomass, live macrophyte biomass, dead macrophyte biomass, and live macrophyte stem density within each microbial mat removal control and treatment plot along each transect at all three sites. Microbial mat dry mass, microbial mat ash-free dry mass, microbial mat chlorophyll-a concentration, and microbial mat organic content for each macrophyte removal control and treatment plot along each transect at all three sites are included as well. Data was collected once from each plot during the data collection period, and one pair of macrophyte removal plots and microbial mat removal plots were randomly sampled on a bimonthly basis until all plots had been sampled. FCE1274_Removal_Experiment_Macrophyte_Biomass includes total macrophyte biomass for each macrophyte species found within each microbial mat removal control and treatment plot along each transect at all three sites. Data was collected once from each plot during the data collection period, and one pair of microbial mat removal plots were randomly sampled on a bimonthly basis until all plots had been sampled. FCE1274_Removal_Experiment_Macrophyte_Density includes total macrophyte stem density for each macrophyte species found within each microbial mat removal control and treatment plot along each transect at all three sites. Data was collected once from each plot during the data collection period, and one pair of microbial mat removal plots were randomly sampled on a bimonthly basis until all plots had been sampled. FCE1274_Removal_Experiment_Macrophyte_Codes includes the taxon codes assigned to each macrophyte species identified in the FCE1274_Removal_Experiment_Macrophyte_Biomass and FCE1274_Removal_Experiment_Macrophyte_Density datasets.

Storage Type: string Measurement Scale: text Missing Value Code: NA (No data collected) Methods Method Step Description FCE1274_Census_Survey: The census observational survey occurred within six temporary wetland regions (< 12-month hydroperiod) during the dry season, which occurs between January and June. The original dataset for the census survey contained 608 sites, but only 140 sites had collected macrophyte and microbial mat biomass data. At each site, the UTM coordinates were recorded, which were from the 17N region and were determined using the datum NAD83. UTMs were converted to decimal degrees using the project() function a part of the terra package (v 1.7.23) in R (Hijmans, 2023). For macrophyte collection, a 60-m transect was established at each site and oriented north to south. Ten 0.25 m2 sub-plots were established along the transect (5, 11, 17, 29, 35, 41, 47, 53, and 59 m) where visualization of the macrophyte community took place as macrophyte species height (cm) and percent cover (%); macrophyte material was only collected at a subset of sites at the 17 and 41 m sub-plots (Ross et al., 2006; Sah et al.,2007). Macrophyte material was collected at 88 of the original 608 sites in 2005 and 88 of the sites in 2006; this material was used along with macrophyte species height and percent cover to determine macrophyte biomass for the 140 sites included in this dataset using a weighted-averaging partial least squares regression (WA-PLS) model conducted by Ross et al. (2006). Water depth was recorded at each sub-plot and four soil depths were measured to determine mean soil depth. For microbial mat collection, three 625 cm2 sub-plots were established within 50 m of each site’s original coordinates, and microbial mat biomass was determined using collected material. At a subset of 100 census survey sites a part of the original 608 census sites, hydroperiods were calculated using three water depths determined at each site and a digital elevation map produced by U.S. Geological Survey. The calibrated hydroperiods from those 100 sites along with macrophyte species percent cover data, which was determined at all of the 608 original census survey sites, were used to predict hydroperiod for the remaining sites using a WA-PLS model; the predicted hydroperiods were therefore termed ‘vegetation-inferred’ hydroperiod and calculated by Ross et al. (2006). Mean annual hydroperiod for the 140 census survey sites included in this dataset was determined using annual hydroperiod values from 1991 to the date that sample collection occurred and using the Everglades Depth Estimation Network (EDEN). EDEN consists of an integrative network of water-level gauges across the Greater Everglades and interpolation models used to calculate daily water-level data and other hydrologic variables like hydroperiod. Annual hydroperiod was determined using EDEN water depth surface values, which were obtained from the U.S. Geological Survey. EDEN values were then corrected against water depths measured in the field using R code and then mean annual hydroperiod was calculated. Lastly, macrophyte community type for each census survey site was determined using macrophyte species percent cover and hierarchical agglomerative cluster analysis conducted by Ross et al. (2006). FCE1274_Transect_Survey: The transect observational survey also occurred within the six temporary wetland regions and during the dry season. Each transect was established perpendicular to the elevation gradient, which corresponded with the present hydrologic gradient within each region. Transect lengths were contingent on the size of the temporary wetland region as well as the length of the present hydrologic gradient; the number of transect sites varied from 26 to 55 for a total of 254 sites. Sites/plots were positioned along the transect 100 m a part except for region B, where plots were positioned 200 m a part for some of the transect. At each site, the UTM coordinates were recorded, which were from the 17N region and were determined using the datum NAD83. UTMs were converted to decimal degrees using the project() function a part of the terra package (v 1.7.23) in R (Hijmans, 2023). Macrophyte biomass was calculated using the same WA-PLS model calibrated using the macrophyte material collected at the 176 census survey sites. Vegetation-inferred hydroperiod was predicted using a WA-PLS model containing the 100 census survey sites with calibrated hydroperiods, and macrophyte species percent cover determined at each transect survey site. Microbial mat biomass, mean soil depth, water depth, and mean annual hydroperiod were determined using the same methods as the census survey (Ross et al., 2006; Sah et al., 2007). FCE1274_Removal_Experiment, FCE1274_Removal_Experiment_Macrophyte_Biomass, and FCE1274_Removal_Experiment_Macrophyte_Density: The macrophyte and microbial mat removal experiment occurred in temporary wetland region B at three wetland sites with varying hydroperiods: site S had a shorter-hydroperiod (ca. 3.8 months), site M had a medium-hydroperiod (ca. 6.5 months), and site B had a longer-hydroperiod (ca. 6.6 months). At each site, the UTM coordinates were recorded, which are from the 17N region and were determined using the datum NAD83. UTMs were converted to decimal degrees using the project() function a part of the terra package (v 1.7.23) in R (Hijmans, 2023); UTMs and decimal degrees for each site are included in the FCE1274_Removal_Experiment data table only. Four, 50-m long transects were established at each site between 2003-05 and 2003-06. Along each transect, 24 pairs of plots were established where 12 plot pairs were control and treatment plots for macrophyte removal (MR) and 12 pairs were for microbial mat (periphyton) removal (PR). MR and PR plot pairs were visually and intentionally paired to maximize the similarity of their macrophyte biomass and composition. PR plot pairs were intentionally chosen to contain low macrophyte biomass and MR plot pairs were chosen to contain high macrophyte biomass. Experimental removal of macrophytes from MR plots and microbial mats from PR plots occurred for one year from 2004-05 to 2005-05, and occurred monthly during the wet season (July – December) and bimonthly during the dry season (January – June). After the removal treatment ended, data collection began. One random pair of MR and PR plots from each of the four transects at each site were harvested on a bimonthly basis until all plots had been harvested, which took from 2004-06 through 2006-04. All macrophyte material and microbial mat material were harvested from each plot, and each plot pair was only sampled once. All macrophyte and microbial mat variables were determined using the material collected from the plots. Macrophyte material was seperated by species, stem numbers were counted for stem density, and stems were oven dried to determine macrophyte species biomass. Kleindl et al. (2025) contains a more detailed description of macrophyte and microbial mat sample processing in the laboratory.

Method Step Description This method step describes provenance-based metadata as specified in the LTER EML Best Practices. A shape file of Everglades National Park was obtained from the National Park Service (NPS, 2024) and used to create a map of data points sampled for this project in the FCE1274_R_Code file. A shape file of the South Florida boundary lines was also used to create a map of data points sampled for this project in the FCE1274_R_Code file. This shape file was retrieved from the State of Florida Boundary Line spatial data available as open source for download application for the Southwest Florida Water Management District.
