Natural Loblolly and Shortleaf Pine Productivity Through 53 Years of Management under Four Reproduction Cutting Methods
A study was ini t ia ted in 1943 to evaluate the longterm product iv i ty of loblol ly (Pinus taeda L.) and shortleaf pines (P. echinata Mill.) when managed under four reproduction cutting methods-clearcut, heavy seedtree, diameterl imit , and select ion-on the Upper Coastal Plain of southeastern Arkansas. Early volume production ref lected retent ion residual pines , and the clearcut was the l...
متن کاملRehabilitation of Understocked Loblolly- Shortleaf Pine Stands- III. Natural Stands Cutover 15 Years Previously but Unmanaged
Plots in an unmanaged loblolly-shortleaf pine (Pinus taeda L.-P. echinata Mill.) stand that had been cutover I5 yrpreviously were established to representfive stocking levels: 10, 20, 30, 40, and 50%. The stand was on a good site (site indexLob = 90 ft at 50 yr) and had uneven-aged character. Two competition control treatments (none and individual tree release using herbicide) were also assigne...
متن کاملStructure and composition of streamside management zones following reproduction cutting in shortleaf pine stands
Streamside management zones (SMZs) in the Ouachita Mountains of Arkansas and Oklahoma are frequently established along headwater ephemeral and intermittent streams to protect water quality, provide wildlife habitat, and increase landscape diversity. To better understand the function of these riparian forest corridors, we characterized the tree density and composition, forest floor mass, and dow...
متن کاملLoblolly Pine Ssr Markers for Shortleaf Pine Genetics
—Simple sequence repeats (SSR) are highly informative DNA-based markers widely used in population genetic and linkage mapping studies. We have been developing PCR primer pairs for amplifying SSR markers for loblolly pine (Pinus taeda L.) using loblolly pine DNA and EST sequence data as starting materials. Fifty primer pairs known to reliably amplify polymorphic markers in loblolly pine were scr...
متن کاملOccurrence of Shortleaf Loblolly Pine Hybrids in Shortleaf Pine Orchards: Implications for Ecosystem Restoration
Shortleaf pine (Pinus echinata Mill.) is an important conifer in much of the southeastern United States. However, the species and its associated ecosystems are in decline, and recent evidence about hybridization with loblolly pine (Pinus taeda L.) raises concerns that the species may be at risk of further losses due to introgression. Although shortleaf pine is not widely planted for timber prod...
