Forest Health ManagementMonitoring Activities

Southern Pine Beetle Activity • Spring Trapping (annual prediction) & Aerial

Monitoring

Gypsy Moth Trapping

Emerald Ash Borer Trapping

Monitor for Sudden Oak Death Pathogen

Forest Health ManagementOther Activities

Cogon Grass• If discovered, Forest Health personnel will

treat the spot at no cost to the landowner. This usually requires a minimum of three annual visits

Invasive Species?

What IS An Invasive?

ANY Plant or Animal that has been introduced.

ANY Plant or Animal that has been introduced and aggressively competes with and displaces local native communities.

ANY Plant or Animal that has been introduced and aggressively competes with and displaces local native communities.Normally having No Natural Enemies to limit reproduction and spread.

Percent Increase

•Imported in 1876

•Erosion Control in the 30’s

•Use Chemical or Biological Control

•Tordon, Transline, or Escort

Chinese Privet

•Imported in 1852

•Planted as an ornamental

•Adapts well to many sites

•Aggressive invasive species

Chinese Privet• By far one of the most invasive species in

Georgia

• Colonizes low wet areas readily

• Spread easily by wildlife (birds)

• Forms dense thicket walls

• Shades and out competes with many native species and once established, is very difficult to remove

Chinese Privet

Control• Because privet is an evergreen, winter time is a

great time to target this species

• Not much else is green during this time

• Very few other things will be harmed by foliar active herbicides like glyphosate (ex. Round-up)

• Most common prescription is a 2% - 5% solution rate of 41% active ingredient products of glyphosate applied evenly over the shrub

Chinese Privet

• Great example of why invasive species need to be controlled

• Without control they have the potential to dominate sites and push out native species

• Reduce the native bio-diversity

Japanese Climbing Fern

• First introduced in 1930’s (ORNAMENTAL)

• Approximately 20,000 acres

• Easily spread in pine straw

• Dies back in late winter

• Dead vines providing a trellis for

re-establishment

• Southern Bark Beetle– Prediction Survey– Aerial Bark Beetle

Survey

• Hemlock Woolly Adelgid

• Laurel Wilt Disease

• Early Detection Rapid Response

• Sudden Oak Death

• Annosum Root Disease

• Cogongrass

• Japanese Climbing Fern

• Chinese Privet

• Exotic Wood Borers

• Emerald Ash Borer

• Gypsy Moth

• Trifoliate Orange

• Tree of Heaven

Ips species (3)

Southern Pine Beetle Dendroctonus frontalis

Black Turpentine Beetle Dendroctonus terebrans

3 Main Types of Pine Bark

Beetles

Southern Pine Beetle

• Without question, has the potential to cause the most damage to timber (more than any other single disease or insect)

• Historically, we have very little damage in South Georgia

• Normally a major problem in North Georgia• Damage goes in cycles

Southern Pine Beetle

Prediction Survey• Usually completed about the time the dogwoods are

beginning to leaf out

Lindgren Funnel Trap

Clerid beetles are natural predators of the Southern Pine Beetle

•Southern Pine Beetle

–Prediction Survey (Spring)

–Aerial Bark Beetle Survey (as needed)

Detection Survey

Pine Beetle Spots Start Small & Spread QuicklyPine Beetle Spots Start Small & Spread Quickly

Pine Beetle Control and Prevention

• Periodic thinning to maintain a vigorous growing stand

• Pre-commercial thinning in young overstocked stands

Too dense

Room To Grow

Our global economy….

The port of Savannah and the Atlanta airport have the potential to bring in many non-native species.
