Abstract Because of a presumed decline in the white-tailed deer (Odocoileus virginianus) herd on the Ocala National Forest in central Florida, mast and available forage were assessed in the forest's two major habitats: sand pine-scrub oak (SP-SO) and longleaf pine-turkey oak (LLP-TO). Deer food was most abundant in young stands of SP-SO and LLP-TO and least abundant in 25- to 40-year-old stands of SP-SO and mature stands of turkey oak. Phosphorus was much lower in simulated diets from all SP-SO stands than the dietary requirement thought necessary for adult deer, perhaps partially accounting for the low reproductive rate on the forest. Availability of deer food can be increased in SP-SO habitat by thinning closed-canopy stands more than 30 years old and, in LLP-TO habitat, by prescribed burning of longleaf pine stands at least once every three years and by removing low-mast producers from mature stands of turkey oak.

The Impact

Abstract Prescribed burning is a common silvicultural practice used in the management of longleaf pine (Pinus palustris Mill., Pinales: Pinaceae) savannas to reduce hardwood encroachment and ground cover and to maintain biodiversity. We investigated the response of the native bee community (Hymenoptera: Apoidea: Anthophila) in the Sandhills of North Carolina to prescribed burning on a 3-yr rotation over two consecutive years (2012 and 2013). We deployed bee bowl traps in sites that had been burned the year of sampling, 1 yr before, 2 yr before, and in unburned controls. In total, 2,276 bees of 109 species were captured. Bee abundance declined with time since fire, with 2.3 times more bees captured in the most recently burned sites than in unburned controls. Bee diversity also declined with time since fire, with 2.1 times more species captured in the most recently burned sites than in controls. Bee community composition also responded to fire; we present evidence that this response was mediated in part by the effect of fire on the amount of bare ground and canopy cover. Bees nesting aboveground were unaffected by fire, contrary to our expectation that fire would destroy the wood and stems in which these species nest. Our results indicate that prescribed burning is a silvicultural practice consistent with pollinator conservation in longleaf pine ecosystems of the North Carolina sandhills.

Mixed Conifer Forest

Prescribed fire is often used by land managers as an effective means of implementing fuel treatments to achieve a variety of goals. Smoke generated from these activities can put them at odds with air quality regulations. We set out to characterize the emission tradeoff between wildfire and prescribed fire in activity fuels from thinning in a case study of mixed conifer forest within the Boise National Forest in central Idaho. Custom fuelbeds were developed using information from the forest and emissions were modeled and compared for four scenarios, as follows: Untreated fuels burned in wildfire (UNW), prescribed fire in activity fuels left from thinning (TRX), a wildfire ignited on the post-treatment landscape (PTW), and the combined emissions from TRX followed by PTW (COM). The modeled mean total emissions from TRX were approximately 5% lower, compared to UNW, and between 2–46% lower for individual pollutants. The modeled emissions from PTW were approximately 70% lower than UNW. For the COM scenario, emissions were not significantly different from the UNW scenario for any pollutants, but for CO2. However, for the COM scenario, cumulative emissions would have been comprised of two events occurring at separate times, each with lower emissions than if they occurred at once.

Conservation Of Biodiversity

The longleaf pine (Pinus palustris Mill.) forest ecosystems of the US southeastern Coastal Plain, among the most biologically diverse ecosystems in North America, originally covered over 24 × 106 ha but now occupy less than 5% of their original extent. The key factor for sustaining their high levels of diversity is the frequent application of prescribed fire uninterrupted in time and space. Pine fuels, critical to application of fire and regulated by canopy distribution, provide the nexus between silviculture and fire management in this system. Typical silvicultural approaches for this type were, in large part, developed to maximize the establishment and growth of regeneration as well as growth and yield of timber, with much less regard to how those practices might influence the ability to sustain prescribed burning regimes or the associated biodiversity. However, many landholdings in the region now include conservation of biodiversity as a primary objective with sustained timber yield as an important but secondary goal. This review synthesizes the literature related to controls of biodiversity for longleaf pine ecosystems, and silvicultural approaches are compared in their ability to sustain natural disturbance such as fire and how closely they mimic the variation, patterns, and processes of natural disturbance regimes while allowing for regeneration.

Vegetation Layer

The frequent fires typical of the longleaf pine ecosystem in the south-eastern USA are carried by live understorey vegetation and pine litter. Mature longleaf pine stands in the xeric sandhills region have a variable understorey vegetation layer, creating several fuel complexes at the within-stand scale (20 m2). We identified three fuel complexes found in frequently burned stands on the Carolina Sandhills National Wildlife Refuge, and used prescribed fire to test whether distinct sets of fire conditions were associated with each fuel complex. Study plots were dominated by either turkey oak or wiregrass in the understorey, or lacked understorey vegetation and contained only longleaf pine litter. Turkey oak-dominated plots had the highest fuel loads, and during burns they had higher total net heat flux than wiregrass- or longleaf pine litter-dominated plots, and longer burn durations than wiregrass-dominated plots. Across all plots, the quantity of litter fragments had the greatest effect on fire temperature and duration of burn. These results show that the patchy understorey vegetation within longleaf pine stands will create heterogeneous fires, and areas dominated by turkey oak may have increased fire intensity and soil heating compared with the other two fuel complexes.

Abstract This research was initiated in a 34-year-old, direct-seeded stand of longleaf pine (Pinus palustris Mill.) to study how pine straw management practices (harvesting, fire, and fertilization) affected the longleaf pine overstory and pine straw yields. A randomized complete block split-plot design was installed with two main plot treatments: (1) no fertilization and (2) fertilization with 45 lb N and 50 lb P/ac in April 1991 and May 1997 and with 50 lb P and 72 lb K/ac in April 2004. There were four subplot treatments: (1) control—no activity except a standwide thinning in June 1999, (2) prescribed burn 6 times from March 1991 through May 2004, (3) prescribed burned as in subplot treatment 2 and pine straw harvested in early 1992 and 1993, and (4) annual harvest of pine straw 13 times from early 1992 through April 2006. Fertilization did not affect longleaf pine growth and yield over the 15-year study. Subplot management also did not influence longleaf pine growth possibly because the adverse effects that competition, repeated prescribed burning, and litter removal have on longleaf pine growth could not be separated among subplot treatments. Fertilization did not directly affect pine straw yields; however, it appeared that pine straw yields decreased over time.

Using Geographic Information Systems and US Forest Service data, we examined relationships between prescribed burning (from 1979 to 2000) and the incidence, size, and intensity of wildfires (from 1995 to 2000) in a landscape containing formerly fire-suppressed, closed-canopy hardwood and pine–hardwood forests. Results of hazard (failure) analyses did not show an increased likelihood of large, small, or intense wildfires with an increase in the number of years since the last prescribed fire. Wildfires of various sizes and intensities were more likely to occur in years with lower than average precipitation, regardless of when these areas were last burned. Calculations of expected lightning-fire potential based on weather patterns predicted a peak in lightning-started fires in the early to late summer. Lightning fires were rare, however, and wildfire activity was greatest in the spring and fall. We hypothesize that the ineffectiveness of prescribed burning in reducing wildfire hazard and the low incidence of wildfires in the midsummer in north Mississippi are both artifacts of fire suppression in the past, which converted open oak–pine woodlands with persistent pyrogenic surface fuels that accumulated over time to closed-canopy forests that lack such fuels. We suggest that open canopies and grass-based surface fuels must first be restored before prescribed burning will achieve most desirable management goals in this region, including hazard reduction and ecological restoration of natural fire regimes.
