Abstract I compared birds present during the breeding season in four forest types in the Conecuh National Forest located on the Gulf Coastal Plain in Alabama: (1) longleaf pine (Pinus palustris) that had been subject to several recent burns, (2) longleaf pine that had been subject to few or no recent burns, (3) planted slash pine (P. elliottii), and (4) various forested wetland habitats ranging from stream-side riparian habitat to cypress (Taxodium distichum) ponds. I found significantly higher total individuals and significantly higher bird species richness in the two natural forest types—burned longleaf pine and riparian habitats—than either unburned longleaf or slash pine. To maintain greatest diversity and abundance of birds, managers of forests on the Gulf Coastal Plain should (1)preserve wetland habitat, (2) not convert stands of longleaf pine to stands of slash pine, and (3) regularly burn longleaf pine stands.

New Information

Plants automatically control the size variations in organs to achieve efficient exploitation of resources. However, it is unclear whether the scaling relationships of plant organs share a similar character for different individuals under varied micro-conditions (e.g., light and soil water). We conducted a case study of the lengths of staghorn sumac leaves and longleaf pine cone scales to test the relationships. Our results indicated that although there were size variations, there existed power laws of frequency in the lengths of staghorn sumac leaves and longleaf pine cone scales. The exponents differed but were positively correlated with the minimum length of leaves or cone scales. Taylor’s Law existed in the lengths of cone scales and some tree leaves, and scale break was observed. This study provides new information on scaling relationships and self-organization in the patterns of tree parts arrangement. Taylor’s Law may be used to detect minor changes in the growth regime.

Abstract Longleaf pine (Pinus palustris Mill) reforestation efforts were successful on the National Forest in south Mississippi when foresters began applying the proper technology. Artificial regeneration by planting bareroot seedlings and natural regeneration by the shelterwood system bothresulted in a plantation success rate consistently above 90%. This success can be attributed to better site preparation, better seedling culture, care, and handling, and more highly trained personnel committed to excellence in longleaf pine regeneration. South.

The U.S. Forest Service has monitored longleaf pine cone production at sites throughout the southeastern United States for over 60 years. Data from the multi-decadal surveys have supported our understanding of the variability of stand-level cone production as it relates to environmental and ecological processes, and more broadly, how longleaf pine operates as a masting species. Cones from longleaf pine are counted each spring using visual surveys that follow a standard protocol. Rapid mast assessments have been proposed in the literature as an alternative to traditional methods, yet these approaches have not been examined for longleaf pine. In this study, I compared average cone production (using the traditional method) to the percentage of trees bearing cones (rapid assessment) to understand the relationship between these two mast measurements. I examined 29 years of data from 18 cone-monitoring sites containing 234 trees. Using simple linear models, I discovered the percentage of trees bearing cones explained 58–94% of the variance in log-average cone production across all sites. One-way ANOVA analysis revealed cone crops required for successful regeneration (25 + cones per tree) occurred when the percentage of trees bearing cones exceeded 90%, and the results from this study underscore the utility of a simple 90% threshold when determining a successful cone crop. While traditional cone-count methods should not be abandoned, I advocate for the use of rapid cone-crop assessments when a proxy approach is suitable.

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.
