Compartment 63, St<strong>and</strong> 11 (26 acres) is a dense loblolly pine st<strong>and</strong> with a build-up of natural<br />

fuels on the ground causing an undesirable fire hazard. Georgia aster (Symphyotrichum<br />

georgianum), a c<strong>and</strong>idate species as listed by the US Fish <strong>and</strong> Wildlife Service (USFWS),<br />

was discovered along with non-native invasive plants including Japanese honeysuckle <strong>and</strong><br />

mimosa (Albizia julibrissin). Georgia aster is a relict species of post oak savanna/prairie<br />

communities that existed in the Southeast prior to widespread fire suppression <strong>and</strong><br />

extirpation of large native grazing animals. It occupies a variety of dry habitats; the primary<br />

controlling factor appears to be the availability of light. The majority of the remaining<br />

Georgia aster populations survive adjacent to roads, along woodl<strong>and</strong> borders, in dry, rocky<br />

woods <strong>and</strong> within utility rights-of-way <strong>and</strong> other openings where current l<strong>and</strong> management<br />

mimics natural disturbance regimes. Most populations are small, <strong>and</strong> since the species’ main<br />

mode of reproduction is vegetative, each isolated population probably represents just a few<br />

genotypes. Many existing populations are threatened by woody plant succession due to fire<br />

suppression, development, <strong>and</strong> highway expansion/improvement <strong>and</strong> herbicide application<br />

(USFWS 2002).<br />

<strong>Commercial</strong> thinning in St<strong>and</strong> 11 will reduce competition <strong>and</strong> stress among residual trees,<br />

enhance growth <strong>and</strong> health, reduce the potential for disease <strong>and</strong> insect infestation, <strong>and</strong><br />

enhance open woodl<strong>and</strong> habitat conditions for wildlife <strong>and</strong> shade-intolerant plant species,<br />

including Georgia Aster. Associated activities required for maintenance of this site, <strong>and</strong><br />

addressed in other decisions (Georgia Aster population <strong>and</strong> Habitat Enhancement Decision<br />

Memo, 2004), include seed collecting, out-planting, monitoring <strong>and</strong> non-native invasive plant<br />

control (USDA, 2009).<br />

This project is consistent with the following goals <strong>and</strong> objectives of the “Revised L<strong>and</strong> <strong>and</strong><br />

Resource Management Plan” (USDA, 2004): Specific goals identified in the LRMP, that<br />

guided this project include:<br />

Goal 10: Continue to the conservation <strong>and</strong> recovery of federally-listed species <strong>and</strong> take<br />

necessary actions to maintain viable populations of all species thereby avoiding the<br />

need to list those species.<br />

o Objective 10.02: Maintain or restore at least 8 self-sustaining populations for Georgia<br />

aster (Symphyotrichum georgianum) …., <strong>and</strong> the habitat to support them.<br />

Goal 14: Manage forest ecosystems <strong>and</strong> associated communities to maintain or restore<br />

composition, structure, function <strong>and</strong> productivity over time.<br />

Goal 17: Manage forest st<strong>and</strong>s so they are less susceptible to insect <strong>and</strong> disease.<br />

o Objective 17.01: Improve forest health on 10,000-50,000 acres of pine forests by<br />

reducing st<strong>and</strong> density.<br />

Goal 20: Maintain <strong>and</strong> restore fire adapted ecosystems by reducing hazardous fuels<br />

through the use of prescribed fire <strong>and</strong> mechanical fuel treatments.<br />
