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 A fourth unpublished dataset provides the GPS locations for all the aluminum posts that mark each of the 11 transects.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
Resprouting of 46 Florida scrub species in relation to fire intensities, burn season, and habitat
We measured responses in 46 species of resprouting plants of Florida scrub and related habitats at Archbold Biological Station following 15 single fires from 2006-2012. Resprouting species were grouped into seven species groups and four habitat types. Burns occurred during either the wet, dry or fire season as defined by Platt et al. 2015. Fire temperatures and residence times were recorded using HOBO data loggers at the base of each marked plant. Survival and growth measures were recorded pre- and for up to eight years post-fire. Fires had variable intensities with maximum temperatures ranging from 47-890 degrees C (mean 549 degrees C) and residence times ranging from 0-83 minutes (mean ten). Consumed plants experienced higher fire intensity than scorched plants, and residence times were higher during the fire season and with drier conditions. Across all species affected by fire, 86% of plants survived and resprouted post-fire. First year survival was unrelated to fire variables with high survival across all maximum temperatures and residence times. Burn season, habitat, and species group did not significantly affect survival. On average across all species, post-fire growth recovered to pre-fire heights within four years. RGR was significantly affected by species group and burn season. Herbs and palmettos recovered relatively rapidly. Recovery was slowest during the fire season, and fastest after burns conducted in the fire season. Resprouting perennial plants that dominate Florida scrub and surrounding habitats appear resilient to a wide range of fire intensities, as measured by maximum temperatures and residence times. Post-fire growth was rapid, with recovery of pre-fire heights in four years. Species groups varied in post-fire recovery rates. In these habitats, fire is critical to maintain the habitat structure for many animals and plants, including many rare species. The slower recovery of biomass for some species like oaks, results in the longer availability
Aboveground Biomass of Florida Scrub Plants
Biomass regressions are useful in non-destructively deriving biomass estimates for many applications. We present aboveground biomass regressions for 14 species of resprouting plants found in pyrogenic Florida scrub and related ecosystems. Aboveground biomass was collected from sites within five time-since-fire classes and predicted by plant height, canopy length, canopy width, species, and time-since-fire class. We were generally able to predict 72-95% of biomass variation from the three plant measurements. Regressions without plant width were almost as successful. For six of the species, time-since-fire affected the allometric equations, so we present regressions for specific time-since-fire classes for these species. Species differed markedly in their biomass equations. Within species groups, individual species usually differed but were similar for Lyonias. These equations will be useful in summarizing species responses to fire frequency and fire intensity in Florida scrub and related ecosystems.
Data from: Fire does not strongly affect genetic diversity or structure of a common treefrog in the endangered Florida scrub
Fire regimes influence natural populations of organisms in diverse ways, via direct effects on population dynamics as well as indirect effects on habitat and ecosystem processes. Although many amphibian species have evolved to persist in fire-dependent ecosystems, the effects of fire on the genetic diversity of amphibian populations remain relatively unexplored. We examined how different aspects of fire history relate to population genetic diversity and structure of an abundant anuran, Hyla femoralis, in a large, intact area of Florida scrub containing hundreds of seasonally inundated ponds. Specifically, we assessed the overall population genetic structure and examined whether variation in time since fire, fire intensity, or historical fire frequency at breeding sites explained spatial variation in genetic diversity. Based on our sampling of 17 breeding aggregations within the 2,100-ha study area, neither recent nor frequent fire reduce genetic diversity or restrict connectivity among ponds for H. femoralis. Overall, mean effective population sizes were large (average range = 68–572). We detected a positive trend between effective population size (Ne) and average intensity of the most-recent fire, with this factor explaining 42% of the variation in Ne. Our results contrast with previous studies that consistently demonstrate strong relationships between fire history and population genetic structure of scrub-associated lizard species, suggesting that H. femoralis is resilient to a wide range of fire regimes. More generally, our study contributes to understanding the roles of life-history characteristics and environmental unpredictability in shaping organisms' responses to fire.
Data for: Fire history and weather interact to determine extent and synchrony of mast-seeding in rhizomatous scrub oaks of Florida
<p>In disturbance-prone ecosystems, fitness consequences of plant reproductive strategies are often determined by the relative timing of seed production and disturbance events, but the role of disturbances as proximate drivers of seed production has been overlooked. We use long-term data on seed production in <i>Quercus chapmanii</i>, <i>Q. geminata</i>, and <i>Q. inopina</i>, rhizomatous oaks found in Southcentral Florida's oak scrub, to investigate the role of fire history and its interaction with weather in shaping acorn production and its synchrony<i>. </i>Acorn production increased with the time since last fire, combined with additive or interactive effects of spring precipitation (+) or drought (–). Furthermore, multiple matrix regression models revealed that ramet pairs with shared fire history were more synchronous in seed production than ones that burned in different years. Long-term trends suggest that increasingly drier spring weather, in interaction with fire frequency, may drive a decline of seed production. Such declines could affect the community of acorn-reliant vertebrates in the Florida scrub, including endangered Florida scrub-jays (<i>Aphelocoma coerulescens</i>). These results illustrate that fire can function as a proximate driver of seed production in mast-seeding species, highlighting the increasingly recognized importance of interactions among reproductive strategies and disturbance regimes in structuring plant populations and communities.</p>

Effects of frequent fire and mowing on resprouting shrubs of Florida, USA, scrub
Background: Resprouting is an effective strategy for persistence of perennial plants after disturbances such as fire. However, can disturbances be so frequent that they limit resprouting? We examined the effects of fire and mowing frequency on eight species of resprouting shrubs (three oaks (Quercus chapmanii, Q. inopina, Q. geminata), three ericaceous species (Lyonia fruticosa, L. lucida, Vaccinium myrsinites), and two palmettos (Sabal etonia, Serenoa repens)) in Florida scrub using a factorial field experiment. We burned or mowed plots at four disturbance return intervals (DRI) – either annually, biennially, every three years, or once in six years (with all plots being treated in the sixth year to control for time-since-disturbance). We analyzed plant growth responses (height, aboveground biomass, number of stems) based on sampling pre-treatment, and six months, one, two, and four years post-treatment. We also measured non-structural carbohydrates (NSC) and soil properties to evaluate these factors as potential drivers of resprouting responses. Results: Fire temperatures were hot (mean maxima 414-698 C among burn days), typical of larger fires in Florida scrub. Plant biomass and heights were affected by DRI (being suppressed by frequent disturbance, especially initially) and varied among species with palmettos recovering biomass faster and species within the same genus generally showing similar responses. Biomass recovery in mown vs. burned treatments showed comparable effects of DRI and similar trajectories over time. Numbers of stems were affected by DRI, disturbance type, and species. Stems increased after disturbances, especially with less frequent disturbances and mowing, and subsequently declined over time. NSC concentrations varied among species and over time and was positively related to biomass. One-year post-disturbance, soil moisture and organic matter content were higher in mown plots, while pH was higher in burned plots. Given the slightly lower eleva
