TL;DR: In this article, the authors compared potential flammability between two ecosystems in the south-eastern coastal plain of the United States, including pine flatwoods and hardwood hammocks.
Abstract: Six understory species from five pine flatwood sites and six understory species from five hardwood hammock sites were harvested for biomass analyses to compare potential flammability between two ecosystems in the south-eastern coastal plain of the United States. Plant components were separated into live and dead foliage, accumulated litter on and under the plant, and small and large stems. Foliar biomass was further analysed for moisture content, volatile solid content, and energy content. Statistical analyses revealed differences among species and between ecosystems. Serenoa repens plants present a wildfire hazard because they contain greater biomass than other species studied. Ilex glabra and Lyonia ferruginea are also hazardous to wildland–urban interface (WUI) structures because they have greater foliar energy content than other species studied. Callicarpa americana plants present the least wildfire hazard to WUI structures. We conclude that differences in flammability among species exist, but the causes of flammability are different among species. In addition, species in the same genus do not always have the same flammability. Based on measured characteristics, understory plants in pine flatwoods have greater ignitability, sustainability and combustibility than understory plants in hardwood hammocks. However, the measurements for consumability were similar between ecosystems.

TL;DR: In this paper, it is shown that the cypress swamps are wetlands, but it is not clear that the intervening pine ecosystems would meet hydrologic criteria of a wetland definition.
Abstract: Cypress/pine flatwoods are a dominant landscape of the lower coastal plain of the southeastern U.S. It is clear that the cypress swamps are wetlands, but it is not clear that the intervening pine ecosystems would meet hydrologic criteria of a wetland definition. Hydrology, as defined by the periodic

TL;DR: From a management perspective, this study suggested newly restored savannas obtain high bee diversity relatively quickly, and small preserves are capable of serving as significant reservoirs of bees.
Abstract: Two longleaf pine savanna communities, upland woodlands and wet pine flatwoods, occur in Louisiana. Because these communities differ in soil profiles, hydrology, topography, and floral composition and diversity, the objective of this study was to determine how bee diversity and composition differed between them. We surveyed three upland woodlands and one flatwood site over a four year period. Our results indicated higher richness and abundance of bees in uplands compared to the wet flatwood. Upland sites consistently contained about 10 more species and 2.5 times as many individuals. Rarefaction curves indicated similar to higher rates of species accumulation of upland sites compared to the wet site. Similarity in species composition was higher between upland sites than between uplands and the wet site. Differences in diversity are discussed in relation to differences between savanna types, age and size of preserves, and fire management. Size of the preserve appeared to be less important than flor...

TL;DR: The results of 2 long-term studies indicate that while it may be best to restore a site with wiregrass obtained from a similar site, it does not seem to be essential to do so, and plant dry mass and diameter were not strongly associated with plant origin.
Abstract: The results of our 2 long-term studies indicate that while it may be best to restore a site with wiregrass (Aristida beyrichinia Trin. & Rupr. [Poaceae]) obtained from a similar site, it does not seem to be essential. In the first study, after 12 y, plants grown on a flatwood site in south-central Florida from seeds collected at a sandhill site (2 locations) in north-central Florida had 83% survival and average aboveground dry mass was 39 g/plant (1.4 oz) with basal diameter of 11.6 cm (4.6 in). In a second study, wiregrass plants from seeds collected at 8 locations (8 entries) across Florida were grown on a flatwood site in central Florida. Four of these entries were also grown on a sandhill site in north Florida. After 4 y on the flatwood site, one entry originating from a nearby flatwood survived better (88%) than the 7 other entries. One entry from a sandhill was notably inferior in survival (3%), but for the remaining 6 entries survival was similar (average 32%). On the sandhill site, the same entry of flatwood origin that had 88% survival on a flatwood had 92% survival, while the other 3 entries averaged 7% survival. Plant dry mass and diameter were not strongly associated with plant origin. Mass averaged 14.8 and 3.1 g/plant (0.52 and 0.11 oz) and diameter averaged 63 and 30 mm/plant (2.5 and 1.8 in) on the flatwood and sandhill sites, respectively.
