Survival, growth and biomass estimates of two dominant palmetto species of south-central Florida from 1981 - 2022, ongoing at 5-year intervals
This data package is comprised of three datasets all pertaining to two dominant palmetto species, Serenoa repens and Sabal etonia, at Archbold Biological Station in south-central Florida. The first dataset, palmetto_data, contains survival and growth data across multiple years, habitats and experimental treatments. The second dataset, seedlings_data, follows the fate of marked putative palmetto seedlings in the field to assess survivorship and growth. The final dataset, harvested_palmetto_data, contains size data and estimated dry mass (biomass in grams) of 33 destructively harvested palmetto plants (17 S. repens and 16 S. etonia) of varying sizes and across habitats. Thirty-two of these were used to calculate estimated biomass, using regression equations, for palmettos sampled in the palmetto_data. Below we summarize experimental setup and data collected for each dataset. Palmetto data Demographic data were collected as three separate components. The first component compared growth among habitats. Starting in 1981, equal numbers of both palmetto species were marked across scrubby flatwoods (oak scrub) and flatwoods habitats (3 sites per habitat) for a total of 240 marked plants. These habitats had not burned within the last decade, but historically had experienced a natural fire return interval of 5 - 20 years prior to this studies initiation. The second component added an additional 400 palmettos (200 of each species), which were marked in sand pine scrub (n = 200) in 1985 and sandhill habitat (n = 200) in 1989 on Archbold's Red Hill. At the time of this project's initiation, all Red Hill management units were last burned in 1927 and were considered long unburned. Part of Archbold's management plan included restoring fire into some management units while leaving others long unburned to serve as reference units. Therefore, for our second component, we were able to create a 2x2 factorial design using habitat types on Red Hill and fire management as factors, with 100

Identifying hotspots of soil legacy phosphorus for soil P remediation on a cattle ranch in the Headwaters of the Everglades, South Central Florida, USA, 2020.
Phosphorus (P) cycling has been altered by human activities across various scales. 'Soil legacy P,' driven by agricultural changes such as excessive P fertilization and manure input, has led to P accumulation in soils. These legacy P reserves are long-term non-point sources, causing downstream eutrophication. Despite considerable scientific and policy interest, the fine-scale spatial heterogeneity, underlying drivers, and scales of variance of legacy P remain poorly understood. This dataset comprises of 1,438 surface soils sampled in 2020 across two typical subtropical grasslands managed for livestock production in South Central Florida, USA. The types of grasslands sampled were Intensively-managed or Improved pastures (IM), and Semi-native (SN) pastures. Chemical analysis was performed on the soil samples to determine three soil legacy P measurements (total P, Mehlich-1 and Mehlich-3 extractable P representing labile P pools) across the landscape. Other variables analyzed includedsoil organic matter, pH, available Fe and Al. Additionally, aboveground biomass samples were collected at a subset of soil sites, and analyzed for P content. The key questions regarding soil legacy P related to: its spatial variability and hotspots, variance distribution, relationship to land management and soil characteristics, and correlation with aboveground plant tissue P concentration. Subsequent analysis and spatial autoregressive modeling from this dataset revealed extreme variability of soil P at small scales, with diminishing variance as spatial scale increased, and increased variance in IM vs SN pastures. These findings enhance our understanding of the underlying drivers, spatial patterns, and variances of soil legacy P. Research suggests that broad pasture- or farm-level best management practices may be limited and less efficient, particularly for high-intensity pastures. Instead, management strategies to reduce soil legacy P could be implemented at fine scales, targeting P hots
Demographic measures of Liatris ohlingerae (Asteraceae) in 20 populations across multiple habitats and time-since-fire intervals in south central Florida from 1997-2017
Demographic data were collected on 2,858 tagged individually marked plants annually from 1997 to 2017 in 20 populations across three sites on the southern end of the Lake Wales Ridge in south central Florida, USA. Our goal was to understand demographic responses including recruitment, survival, reproduction and mortality of individuals across populations, habitat types and fire-return-intervals. Habitats include rosemary scrub, scrubby flatwoods and human created sandy roadsides. Populations spanned three sites including Archbold Biological Station (18 populations), Florida Forest Service Arbuckle Tract of the Lake Wales Ridge State Forest (1 population), and Florida Fish and Wildlife Conservation Commission Gould Road property (1 population). Annual demographic measures include survival (including plant dormancy), stage, measures of size, reproductive effort and herbivory. Plots were surveyed annually during flowering in August for previously marked plants and searched for newly recruited putative seedlings or previously missed larger adults. This landscape is managed with periodic prescribed fire impacting some populations with additional post-burn censuses completed after the burn. In addition, damage following three hurricanes in 2004 were recorded. Plants were followed through their lifecycle and after four years of no aboveground growth, plants were assumed dead and tags removed from the field.

Drivers of algal abundance in edge of ranch and internal ditches on a south-central Florida ranch, 2023.
Although algae blooms are historically common in Lake Okeechobee and surrounding waterways, blooms in recent years have covered much of the lake’s surface and have contained toxin-producing groups of algae, rendering them harmful algae blooms (HABs). South Florida Water Management District and other entities have taken strides to manage interior waterways before nutrient-rich freshwater reaches downstream estuaries along the coasts. Because ranching is the largest land use by area in the Lake Okeechobee watershed, ranches may be able to improve HAB mitigation strategies by holding water, and therefore nutrients, in private wetlands and ditches. Our study assesses water quality within 19 ditch sites on Buck Island Ranch (BIR), a working cattle ranch in south-central Florida. Sites were sampled monthly for nutrient concentration, temperature, conductivity, pH, dissolved oxygen, turbidity, site characteristics, and chlorophyll a concentration as an indicator of algal biomass. We analyzed relationships between chlorophyll a, nutrient concentrations, and biophysical parameters to establish possible drivers of algal abundance in the ditches. We expected higher chlorophyll a concentrations during periods of higher nutrient concentrations and higher light availability. Higher chlorophyll a concentrations were also expected in the internal ranch ditches, as these sites bordered pastures that have been historically fertilized. Results suggested that ditch location, total nitrogen and total phosphorus explained the most variations of chlorophyll a concentrations in ranch ditches. Our research indicates that nutrient fluxes contribute to general algae growth within cattle ranches in the Lake Okeechobee watershed, potentially contributing to downstream water quality affects. Future research could demonstrate the effects of ranch management on specific types of algae blooms, distinguishing between diatoms, harmful algae, and other algal groups.
A case study of the effects of wetland restoration on the hydrology, species diversity, species composition and floristic quality of restored wetlands within a Central Florida ranchland, 2003 - ongoing.
In the USA the United States Department of Agriculture (USDA) Natural Resource Conservation Service (NRCS) has restored millions of acres of wetlands through its Wetland Reserve Easement (WRE) programs. However few quantitative studies have explored whether WREs have enhanced wetland hydrology and wetland plant communities. Additionally USDA Compatible Use Permits for cattle grazing and other management practices are sometimes issued for WREs but little is known about potential benefits/detriments of such practice on the success of wetland restoration. In this study we tested if hydrological restoration of previously drained species poor pastures increased water depth and hydroperiod. Restoration involved plugging key ditches adding water control structures and a berm. We also tested if hydrological restoration increased plant diversity (alpha and beta) floristic quality (using coefficient of conservatism) and increased the cover of wetland species (using species wetland status). Finally we tested if cattle grazing had an effect on the success of restoration by comparing grazed plots to fenced plots. We studied two conservation easements (a total of 748 acres) located on semi-native pastures in central Florida USA. We monitored vegetation using permanent transects stratified by vegetation type before (2004-2005) and after (2012) the restoration (2008). We assessed wetland hydroperiod using groundwater wells set up in 2003 and located within and outside the boundaries of these two easements.
Demography of the rare herb, Polygala lewtonii (Polygalaceae), with multiple fires on the Lake Wales Ridge in south-central Florida from 2001-2017 (ongoing)
Demographic data on 5,060 individually marked plants of the endemic State and federally listed Polygala lewtonii (Lewton's milkwort; Polygalaceae) were collected from December 2001 to December 2017 at the Lake Wales Ridge National Wildlife Refuge Carter Creek in south-central Florida, USA. Data collection is still ongoing. In 220 permanent 25 cm radius circular plots, plants were marked with plastic toothpicks and wire stake flags with a unique identification number. Data collection occurred quarterly with survival and recruitment recorded in March, June, September and December and more detailed measures of size and fecundity taken in March. This species is amphicarphic with both showy-open flowers produced in spring (chasmogamy) and closed, self-pollinating flowers both above- and belowground produced in late summer (cleistogamy). Therefore, our fecundity data are based only on chasmogamy. This dataset also captures post-fire mortality and recruitment events following four prescribed burns.

Monitoring of vegetation and fire in Florida scrub, flatwoods, and wet prairie in south-central Florida from 1977-2015
This data package is comprised of three datasets all pertaining to the impacts of prescribed fires and wildfires on vegetation at 11 permanent transect sites over nearly four decades at Archbold Biological Station (ABS) in south-central Florida. Data were collected between 1977 to 2015 in wet prairies, flatwoods, oak scrub, rosemary scrub, and hickory scrub. The first dataset, cover_data, contains year and month of sampling at a given transect site, the vegetation association type, burn unit, and the percentage cover data for sampled species and bare ground. The second dataset, fire_occurrence, includes the dates of each fire that impacted each transect site, the burn unit of the transect, and the percentage of transect burned. The third dataset, species_information, includes the scientific name, common name, plant family, and nativity of each sampled species. A fourth unpublished dataset provides the GPS locations for all the aluminum posts that mark each of the 11 transects. These data are available from the Archbold data manager. Below we summarize the setup and data collected for each dataset. Cover_data: We determined the percentage cover (i.e., dominance) of each encountered species at 11 vegetation stands including two wet prairies (WS20, WS21), three flatwoods (WS30, WS42, WSP1), and six Florida scrub associations including four oak scrubs (WS26, WSP2, WS24, WS25, the latter two include areas of rosemary scrub), a rosemary scrub (WS27), and a hickory scrub (WS29). Each stand was sampled at selected times, ranging from five to as many as 12 repeated samplings, during the 38-yr period beginning in 1977 and continuing to 2015. Stands were sampled during January (mid-way during the winter dry season) except for sampling four stands in May 1977 and eight stands in July 1977 to document short-term 4-month and 6-month vegetation recovery following the initial January 1977 prescription burn. At each permanently marked transect site, we sampled 200 m using two parall
