“…Frequent prescribed fire reduces small hardwoods and shrubs resulting in a corresponding increase in grasses and forbs creating open, park-like conditions (Waldrop et al 1992, Brockway and Lewis 1997, Glitzenstein et al 2012. Additionally, frequent prescribed fire in pine savannas increases understory plant species richness, diversity, and evenness (Brockway and Lewis 1997), which potentially provides wild turkeys with an abundance of suitable nesting habitat.…”

“…However, changes in government policies have encouraged landowners to exclude fire from their properties (Alavalapati et al 2002). Without fire disturbance, longleaf pine savannas are replaced by hardwoods and other pine species (Landers et al 1995, Glitzenstein et al 2012. Fire is also beneficial to fauna found in a fire-maintained system, as it promotes availability of nesting and brood-rearing cover for groundnesting birds (Dickson 1981, Hurst 1981, Landers 1981 and maintains open, park-like conditions needed by species such as the endangered red-cockaded woodpecker (Picoides borealis; Alavalapati et al 2002).…”

Introduction: Reproductive success is a critical factor affecting avian demographics and can be influenced by many factors including nesting chronology, predation risk, and fine-scale nest site selection. Methods:We modeled the relative influences of habitat-related covariates at six spatial scales (nest site: 15-, 40-, 80-, 120-, 160-, and 200-m radii) on Eastern wild turkey (Meleagris gallopavo silvestris) nest site selection in two pine savannas managed by frequent prescribed fire (≤3 years) in southwestern Georgia during 2011-2013.Results: Nest site (15-m scale) habitat metrics (mean visual obstruction [cm] and canopy closure [%]) had the greatest influence on nest site selection relative to covariates measured at larger spatial scales. Scaled odds ratios suggested that nests were 26.8 % more likely to occur for every 10 cm increase in mean vegetation height with a range of 7.5 to 150.0 cm and 18.5 % less likely to occur for every 10 % increase in canopy closure with a range from 0.0 to 97.8 %. Total ground cover, canopy closure, edge density, and percent land cover type (e.g., mature pine, mixed pine/hardwood, shrub/scrub) had minimal influence on nest site selection.Conclusions: Management of pine savannas for turkey nest sites should focus on creating early-successional vegetation to conceal nests from potential predators. Additionally, we suggest that future studies consider evaluating the influence of spatial scale on turkey nest site selection.

“…The study utilized research plots established on old field land for long-term study of fire regimes. The Stoddard Fire Plots, which are 0.2 ha plots established in 1960, have each been managed with a constant fire return interval until the present [10,23,24]. The study also utilized a 9.2 ha plot named NB66 that had been fire-excluded since 1966 [24].…”

“…Prior to establishment of the plots, the areas had been burned at 1-2 year intervals since agricultural abandonment which occurred from the late 1800s to the 1920s. Soils within the sites were heavily cultivated for growing corn and cotton from the 1820s until abandonment with subsequent understory and overstory vegetation assemblages highly influenced by past agricultural practices [23] but largely representing a subset of species occurring in native pine communities of the region [10,25]. Soils were classified as fine-loamy, kaolinitic, thermic Typic Kandiudults of the Orangeburg and Faceville series (Natural Resource Conservation Service (NRC) Soil Survey Geographic Database (SSURGO)).…”

Soil CO 2 efflux (R s ) is a significant source of carbon dioxide from soils to the atmosphere and is a critical component of total ecosystem carbon budgets. Prescribed fire is one of the most prevalent forest management tools employed in the southeastern USA. This study investigated the influence of prescribed fire on R s rates in old-field pine-grassland forests in north Florida, USA, that had been managed with prescribed fire annually and biennially for over 40 years, or left unburned for approximately the same period. Monthly measurements were taken of R s , soil temperature (T s ), and soil moisture from August 2009 to May 2011. Results showed that sites managed with annual and biennial dormant season prescribed fire had significantly lower monthly mean R s rates and estimated annual soil carbon fluxes than sites where fire had been excluded. While T s explained a significant amount of the temporal variations in R s , it did not explain the differences in R s among prescribed fire treatments. Our results provide new insight into the effects of prescribed fire and fire exclusion on soil carbon fluxes, and suggest that future methods to model ecosystem carbon budgets should incorporate not only current vegetative conditions, but also prescribed fire management activities.

“…Various wildlife species found in longleaf pine savannas, such as the endangered red-cockaded woodpecker Picoides borealis and gopher tortoises Gopherus polyphemus are dependent on the use of fire to maintain open, park-like conditions for their survival (Alavalapati et al 2002). Therefore, land managers commonly apply prescribed fire every 1-3 years to reduce hardwood encroachment and enhance grass and forb development in longleaf pine savannas (Glitzenstein et al 2012). Wild turkeys have been an economically important upland game bird since reintroduction and restoration efforts (Baumann et al 1990).…”
