“…Finally, the impact of modeled changes on the local biodiversity was not assessed. Spatial prioritization studies have shown that a higher probability exists for new longleaf pine plantations on those croplands and pasturelands that are closer to existing plantations supported by various federal and state programs [57]. We have included any potential land cover changes in the context of longleaf plantations in this study.…”

Longleaf pine once covered 37 million hectares in the southern United States. However, it currently occupies only 5% of the original area. Efforts have been ongoing for the last decade to restore longleaf pine. The expected expansion in the area under longleaf pine has raised concern among wood-consuming mills regarding a potential increase in the total wood procurement cost, as wood availability per unit of land is typically lower for longleaf than for loblolly and slash pines for the first few decades. Therefore, a simulation model was developed in this study, examining the impact of the gradual adoption of longleaf pine by landowners on the total wood procurement cost of a pulp mill located in South Georgia over a 40-year simulation period. Results show no statistically significant difference between scenarios for maximum distance, total cost, and total distance over the simulation period. Our study will guide stakeholder groups to balance the needs for longleaf pine restoration and the reduced cost of wood procurement for wood-consuming mills.

“…An additional factor that may influence the wood quality of planted longleaf pine is that the re-establishment has occurred on two primary land site types, on cutover forest sites where the prior rotation was trees (likely loblolly pine, slash pine, or natural longleaf pine), or on old agricultural fields where the prior crop was something other than a tree (Hainds 2004;Johnson and Gjerstad 2006;Kush et al 2006). Approximately 86% of the total longleaf pine plantations established through the Conservation Reserve Program (CRP) can be found on old agricultural fields (Paudel et al 2021). Old agriculture fields have different soil characteristics, with significantly more available nutrients from the repeated fertilizer applications on the prior crops, and essentially no hardwood competition through the first thinning as compared to cutover forest sites (Clabo et al 2020).…”

Efforts to restore longleaf pine across the southeast United States have occurred on two distinct site types, cutover forests and old agricultural fields. We measured wood and bark physical properties of unthinned planted longleaf pine from sixteen stands across Georgia, ages 12 to 25, with eight stands sampled from each site type. Three-hundred and twenty trees were felled and 3,572 disks collected from within the trees. Wood and bark specific gravity (SG), moisture content (MC), and proportion of bark were measured. Non-linear mixed effects models were developed to predict the variation in wood and bark SG with respect to relative height, age, and site type. Cutover sites had higher whole-tree wood SG (0.504 vs 0.455) and bark SG (0.374 vs 0.347) than old agricultural fields. The models explained 50% and 37% of the variability in wood and bark SG, respectively. Moisture content models were fitted as a function of SG for wood (R2 = 0.87) and bark (R2 = 0.71). Bark thickness, dry mass, and green volume were higher for cutover forest sites. Trees sampled included both non-defect and defect-containing trees, however, no significant differences in the wood physical properties were found. These results provide important information for the utilization of plantation longleaf pine.

Black and female landowners, two of the largest groups of underserved landowners in the southeastern US, have considerably less land enrolled in the US Department of Agriculture's Conservation Reserve Program (CRP) than White and male landowners. The reasons for this discrepancy are complex and interrelated. Previous studies approached different facets of this problem using a variety of methods and analyses. Here, we conducted a synthetic literature review that demonstrates how the intertwined ecological, economic, and cultural concerns of underserved landowners influence their decisions about potential land conversion in the context of CRP requirements. Other studies have rarely considered such relevant factors as the sociocultural importance of land to underserved populations or the links between the limited participation of these groups in the CRP and historical racism and sexism in land management industries and agencies. Explicitly addressing these issues will help promote conservation equity in the CRP and other conservation programs.
