“…The results also suggest that forest fire managers should pay particular attention to the respective thresholds of each fuel type when carrying out a prescribed burn. Information from this laboratory experiment should provide fire managers in northeast China greater understanding of the requirements of prescribed burning and the level of good-practice guidelines, allowing them to adjust management to meet the criteria (Charles and Garten 2006;Wang et al 2013). This will contribute to the preservation of both biodiversity and the provision of ecosystem services (Allen et al 2016).…”

content and spread fire at 25% moisture content using cigarette butts. A two-way ANOVA showed that both the source of ignition and the wind speed affected ignition and fire spread threshold significantly, but there was no interaction between these factors. The relationship between ignition and fire spread was strong, with R 2 = 98% for cigarette butts, and 92% for matches. Further information is needed, especially on the density of fuels, fuel proportion (case of mixed fuels), fuel age, and fuel combustibility.

“…Fort Benning uses prescribed burning to remove understory vegetation on almost approximately 3‐year fire return interval. There are minor predicted effects of prescribed burning on forest recovery or sustainability (Garten 2006) as well as measured minor effects on soil A‐horizon depth and the composition of understory vegetation (Dilustro et al 2006). However, an analysis of a subset of sites indicated no difference among land use categories with respect to years since the last burn ( p = 0.67, one‐way analysis of variance; reference forests = 2.3 years, n = 12; reforested = 1.9 years, n = 13, and disturbed = 1.8 years, n = 13).…”

We present results on changes in soil properties following land use change over an approximately 55-year period at Fort Benning, Georgia, U.S.A. Soil cores were taken at 129 locations that were categorized as reforested (field/ bare ground in 1944 and forest in 1999), disturbed (field/ bare ground in 1944 and 1999), or reference forests (forest in 1944 and 1999). Soil disturbance included historic agriculture (pre-1944) and military training (post-1944). Density in mineral soils exhibited a historic land use legacy effect (reference < reforested < disturbed). Rates of change in bulk density decreased with depth and estimated total times to reach reference forest levels ranged from 83 (0-10 cm) to 165 (30-40 cm) years. A land use legacy effect on C stock was apparent in the O-horizon and in 30-to 40-cm soil increment (reference > reforested > disturbed). Soil C stock in all other increments and in particulate organic matter was affected by disturbance; however, no legacy was apparent (reference = reforested > disturbed). For the entire soil profile (O-horizon to 40 cm), rate of C accrual was 28 g m 22 yr 21 (1.5%/yr). Nitrogen stocks were affected by disturbance in the O-horizon and 0-to 10-cm increment; however, no legacy effect was detected (reference = reforested > disturbed). Nitrogen accumulated at 0.56 g m 22 yr 21 (0.6%/yr) for the entire soil profile. At Fort Benning, soil C and N stocks of reforested stands were similar to those of reference forested stands after approximately 55 years. However, soil bulk density was greater on reforested stands than reference forest stands at 55 years and may require an additional century to reach reference levels.

“…Recently, Garten (2006) used a simple compartment model to predict the effects of prescribed burning at Fort Benning without considering biological nitrogen input, such as symbiotic and nonsymbiotic N 2 fixation; this could lead to significant biases both in scientific research and land management decisions since biological N 2 fixation may play an important role in replenishing N loss from fire.…”

“…In this study, we simulated C and N cycles at relatively infertile longleaf pine sites at Fort Benning. Key model parameters, including C: N ratios of plant tissues, soil, atmospheric N deposition rate, symbiotic and nonsymbiotic N 2 fixation, and C allocations among plant parts were either measured from previous studies (DeBusk et al, 2005;Garten and Ashwood, 2004a) or taken from literature review (DiStefano and Gholz, 1989;Hendricks and Boring, 1999;Lajeunesse et al;2006). Meteorological data (monthly precipitation and temperature) were from on-installation weather stations.…”
