Abstract Fifteen plantations of sand pine (Pinus clausa var. clausa (Chapm.) Vasey; P. clausa var. immuginata D. B. Ward) in the sandhills of South Carolina were examined. Stands ranged from 3 to 16 years of age, and sand depth ranged from 3.5 to more than 9 feet. Most stands were adequately stocked with more than 400 trees/acre. At this density, an average 14-year-old stand of sand pine produced an annual increment in excess of 60 ft³/acre of wood, which was approximately twice that of other commonly planted species. There were no serious problems from insects or diseases, and ice storms had not caused noticeable damage in the stands that were sampled.

Effects of permanent (i.e., maintained) and temporary edges with north- and south-facing exposures were studied in sand pine (Pinus clausa var. clausa) scrub, an open-canopied forest type in Ocala National Forest, Florida. On edges and interiors of four stands of each type, we measured canopy tree architecture in 5 x 100 m plots and stand density and basal area in 5 x 200 m plots. Edge effects were modest but often stronger on south- than north-facing edges and along permanent forest roads than temporary edges of clearcuts that were allowed to regrow. Compared to interior trees, those on edges were typically shorter, retained branches lower on their boles, oriented their first branches more towards the edge, and produced more asymmetrical crowns with the long axis extending into the opening; these trends were greater on south- than north-facing edges and along permanent than temporary edges. Contrary to expectations, there were no edge effects on total basal area, dead tree densities, proportions of sand pine trees with leaning trunks, directions of lean, or angles of lean. Instead of an edge effect, most trees leaned southwesterly, which seems related to the northeastern origin of prevailing winds and wind gusts.

Abstract Ocala (Pinus clausa var. clausa Ward), Choctawhatchee (P. clausa var. immuginata Ward), and Withlacoochee sand pines were established in 1970 at seven sites from Walton Country in northwest Florida to Volusia County in east-central Florida. After five years, the Choctawhatchee source had uniformly good survival but the lowest height. The Withlacoochee source was characterized by good height and intermediate survival. Ocala sand pine had the poorest survival and the greatest height. The Choctawhatchee source seems most suited for large scale reforestation, while the Withlacoochee source has potential for more widespread use than it is currently receiving.

Abstract Choctawhatchee sand pine (Pinus clausa var. immuginata D.B. Ward), Ocala sand pine (P. clausa var. clausa D.B. Ward), slash pine (P. elliottii Engelm.), loblolly pine (P. taeda L.), and longleaf pine (P. palustris Mill.) were grown on sandhills in Georgia and South Carolina. Choctawhatcheesand pine grew fastest and yielded the most volume after 28 yr. Productivity equaled that of plantations in northwest Florida, averaging more than 100ft³/ac/yr. To maximize yields for pulpwood rotations of 25 to 35 yr, managers should plant these sites to Choctawhatchee sand pine. Longleafpine, however, has been growing as fast as Choctawhatchee sand pine since age 15 yr. Therefore, especially for longer rotations, it would be an acceptable alternative species. South. J. Appl. For. 17(2):00-00.

Abstract Cold storage was found to keep Choctawhatchee sand pine (Pinus clausa var. immuginata Ward) seedlings in good condition for planting for as long as 12 weeks. Seedlings were lifted in mid-November, December, January, and February; stored in KP bags at temperatures in the thirties (°F) up to 12 weeks, and planted from November through May. Survival was good, averaging 90 percent despite significant differences in lifting date and storage interval. Survival was lower for seedlings stored longest. Those lifted early showed low survival only in the second installation of the study, where dormancy was delayed by warm, wet fall weather. Differences in survival could not be correlated with seedling size, morphology, or nutrient content, nor with temporary disruptions in the temperature regime of the cold storage unit due to heavy use or equipment failure.

Abstract Initiation and duration of viable pollen production differed significantly among clones of Choctawhatchee sand pine (Pinus clausa var. immuginata Ward). Clonal differences also occurred for pollen germinability, pollen conductivity, and catkin moisture content, but clonal differences for these traits were influenced by the stage (early, intermediate, or late) of pollen production. Pollen germination decreased only 10 percent from early to late pollen production, suggesting that viable pollen may be collected during any period of pollen shed. Relationships among the three measures of pollen viability, although significant, were weak. Conclusions drawn will aid tree breeders in making controlled pollinations and in establishing seed orchards.

Abstract On the Georgia and South Carolina sandhills, planted sand pines [Pinus clausa (Chapm. ex. Engelm.) Vasey ex. Sarg.] grew better than loblolly (P. taeda L.), longleaf (P. palustris Mill.), and slash pine (P. elliottii Engelm.). Heights at age 15 averaged 35.4 feet for the Choctawhatchee variety of sand pine (P. clausa vat. immuginata Ward), 32.8 feet for the Ocala (P. clausa var. clausa Ward), and 22.6, 23.8, and 24.0 feet for loblolly, longleaf, and slash pine, respectively. Ocala sand pine had good height and diameter growth but poor initial survival and suffered most damage from an ice storm at the South Carolina site. Damage to the Choctawhatchee variety was no greater than that to longleaf or slash pine. Comparison with Florida stands of a similar age shows the Choctawhatchee variety growing as well in Georgia and South Carolina as within its natural range.
