WILD Facts
Why do leaves change color in the fall? Shorter days and cooler weather trigger “hibernation” in deciduous trees (trees that lose their leaves). Water and nutrients are shut off from the leaves in order to store energy in the branches and trunk for the winter. Chlorophyll, the compound that makes leaves green, then becomes depleted, allowing one or more other leaf compounds to show color. Carotene produces yellow, orange and brown leaves while anthocyanin gives leaves a red or purple hue. The increased level of stored sugars and proteins in the trunk also acts as an antifreeze to protect the tree from cold temperatures.
In educationChinese privet, kudzu, cogongrass: These and other alien invaders from the plant realm are for real in Georgia. Educators who want to teach their students about exotic invasive plants can turn to the
Georgia Exotic Plant Pest Council. The council’s Web site offers
k-12 curriculum and activities aimed at raising awareness about the impact of invasives. The state chapter of the
Southeast Exotic Pest Plant Council says teachers can use these tools to “help students develop a sense of stewardship for our wild places.” Other resources include the newly completed
Georgia Invasive Species Strategy, which covers problems and possible actions involving invasive plants and animals in Georgia, and the 2009 Georgia Exotic Pest Plant Council's
Annual Symposium, Nov. 5 at the State Botanical Garden of Georgia in Athens.
D.C. talk
Good news for State Wildlife Grants. A compromise over House and Senate differences in the new
Interior, Environment and Related Agencies Appropriations Act will raise fiscal year 2010 funding for State and Tribal Wildlife Grants to $90 million, $15 million more than last year. Appropriators also agreed to cut the nonfederal match required for grants from 50 to 35 percent for implementation projects, according to the
Teaming With Wildlife coalition. The match reduction is a first, and the funding is the most ever for State Wildlife Grants, the key funding source for State Wildlife Action Plan projects. Georgia is due a raise: The state was budgeted $1.6 million for fiscal 2009. Final passage in Congress is expected soon.
As for another conservation initiative, there is bipartisan support for making enhanced tax deductions for conservation easement donations permanent, via
HR 1831 and
S 812. The Land Trust Alliance says the easements have
conserved at least 535,000 acres since 2006, allowing moderate-income landowners to protect land while receiving tax benefits for easements. For information on conservation easements in Georgia, call (770) 761-3043.

Georgia aster
Symphyotrichum georgianum
Also called:
Aster georgianus or
Aster patens var. georgianus.
Family: Asteraceae (Aster/composite family).
Key characteristics: This Colonial perennial herb reaches eight to 60 inches tall, with 2-inch-wide flower heads with rays ranging from bright violet to dark, reddish purple. The disk flowers are a reddish purple. Thick, hairy green leaves with pointed tips alternately clasp the stem.
Range: Scattered locations in Georgia, Alabama, North Carolina, South Carolina and Florida. Most remaining populations are on private land; a small percentage are on federal lands. Most Georgia populations are in the upper Piedmont.
Habitat: Oak-pine-hickory woodlands and Piedmont grasslands, old fields and other open, historically fire-prone habitats. Also found in thin soils around granitic flatrocks. The extreme rarity of this habitat has relegated Georgia aster largely to forest edges, utility rights of way and roadsides.
Reproduction: Self-sterile flowers bloom from late September through mid-November. Flowers from separate genetic stock (not in the same colony) are required for sexual reproduction. Most reproduction is, therefore, vegetative. Viable fruits are dry, hairy seeds 1/8-of-an-inch long.
Status:
Threatened in Georgia with less than 20 populations believed extant, or not lost. Most are quite small; many are in poor condition. Eight occur on public lands. Also listed as threatened in North Carolina. Considered a candidate for federal listing.
NatureServe rates the species imperiled at global and state levels.
Threats: Habitat alteration and loss, and prolonged and widespread lack of fire. Georgia aster colonies along
roads and in rights of way are also subject to invasive exotic species such as kudzu, highway expansion, quarrying and herbicide application. Rather than mowing, many utility companies and railroads use herbicides to better control vegetation. Surviving Georgia asters in an area may be from a single clone, and unable to produce viable seed.
Conservation: The
U.S. Fish and Wildlife Service is encouraging landowner cooperation to protect and manage Georgia aster populations. The
U.S. Forest Service has agreed to conduct prescribed burns on some of their sites. In addition to prescribed burning in the winter or early spring, mowing will help maintain openings. Soil disturbance and herbicides should be avoided and exotic species eradicated. Avoid clearcutting.
Conservation in Georgia: The
Nongame Conservation Section, in cooperation with the
Georgia Plant Conservation Alliance, is restoring Georgia aster habitat and populations throughout the Piedmont. A robust population in Paulding County at
Pickett’s Mill Battlefield Historic Site is being managed through mowing and prescribed fire to maintain high-quality open meadow habitat. Several new populations have been established as safeguarding sites on Forest Service land near Currahee Mountain in Stephens County (
"Currahee gets rare plants," December 2008). The sites are part of an ambitious Piedmont woodland restoration project that includes thinning of woody competition and the reintroduction of prescribed fire into fire-suppressed habitats. Additional outplantings at Currahee are planned, as well as new restoration and safeguarding projects at Broad River Wildlife Management Area in Elbert County and Wilson Shoals WMA in Banks County.
The Nature Conservancy is working with
Georgia Power, DNR and others in the GPCA to improve a population found at Goat Rock Reservoir in 2008.

Wildlife Resources'
Nongame Conservation Section conserves and protects Georgia's diversity of native animals and plants and their habitats through research, management and education. The section depends for funding on grants,
donations and fundraisers such as
nongame license plate sales, the
Give Wildlife a Chance state income tax checkoff and
Weekend for Wildlife. Call (770) 761-3035 for details on direct donations. The nongame plates -- the bald eagle and ruby-throated hummingbird -- are available for a one-time $25 fee at all county tag offices, by checking the wildlife license plate box on mail-in registration forms or through online renewal.
