Avoiding Perilous Vines When Hiking and Camping in Georgia

Looking Out for Hazardous Vines When Exploring the Georgia Outdoors

Georgia's warm climate allows dense vegetation to thrive across its forests, meadows, and swamplands. But some vines commonly found in the region can cause painful rashes and injury with mere touch. Identifying poisonous vines prepares outdoor enthusiasts to avoid their risks when hiking, camping, or adventuring in Georgia.

Poison Ivy

Poison ivy is the most notorious poisonous vine found in the Eastern and Central US. All parts of the plant contain an oily resin called urushiol that causes an itchy rash in most people.

Poison ivy vines have clusters of three leaflets. Leaves can be green or reddish depending on season and plant maturity. Fine hairs on the vines and leaves make poison ivy identifiable.

The rash develops in streaky lines following where plant oils contact the skin. Blisters may form and ooze fluid. Poison ivy rashes last 14-28 days.

Poison Oak

Poison oak is often confused with poison ivy since both plants induce the same rash. But poison oak has leaves resembling oak tree leaves - lobed rather than smooth edged.

Poison oak can take the form of a vine or climbing shrub. Its leaf clusters contain 3 leaflets like poison ivy. White flowers and berries emerge after the leaves.

Urushiol on poison oak also penetrates clothing and stays active on dead vines up to 5 years! Rashes require calamine lotion, antihistamines, or steroids.

Blackberries

Wild blackberry vines bear delicious berries but have thorny stems that can deliver painful scratches. Thorns may break off under the skin, causing injury and infection risk.

Blackberry shrubs grow aggressively, forming impenetrable thickets with recurved thorns. Gloves, long sleeves and pants offer protection when picking wild blackberries.

Smilax Vines

Greenbriers or catbriers belong to the Smilax genus - spiny, woody vines that climb shrubs and trees. They have oval leaves emerging alternately along the stem.

Sharp, downward-curved prickles run along the vine to deter animals. Greenbrier scratches can infect skin. Sawbriers have larger hooked prickles that can cut deeply.

Honeyvine Milkweed

A perennial vine milkweed, honeyvine milkweed grows thin trailing stems along the ground or up fences and shrubs.

Oval leaves with edges variably smooth to wavy distinguish this plant. Crushed stems and leaves exude a milky sap containing poisonous cardioactive glycosides.

Ingesting honeyvine milkweed parts, especially the pods and roots, can cause vomiting, diarrhea, and abnormal heart rhythms in humans.

Grape Vines

Wild grape vines thrive in Georgia's climate. Muscadine grape vines have shredding bark and tendrils for clinging onto supports.

The sap, leaves, stems, and unripe green grapes contain toxic compounds like oxalates that can irritate the skin. Some people experience allergic rashes from handling wild grapes.

Virgina Creeper Vine

A popular decorative vine, Virginia creeper displays gorgeous red fall foliage. But contact dermatitis can occur from the oxalate crystals and sap.

The vine uses small adhesive pads on tendrils to climb up brick and wood. Rashes present like reddened patches and small blisters.

Trumpet Creeper Vine

Trumpet creeper vine, also called cow itch, has large orange trumpet-shaped flowers. Tiny stiff hairs on the vines and leaves inject chemicals causing severe itching and rashes.

The vine averages 30 feet in height. Aphids on the plant secrete the irritating substance when threatened. Avoiding skin contact prevents reaction.

Dangerous Georgia Swamp Vines

Poisonous vines thrive in the boggy, acidic soils of Georgia's swamp areas. Some hazardous vines to avoid in swampy habitats include:

Rattan Vine

A robust, sprawling vine found in southeastern US swamps. Also called rattan weed, its flexible stems have hook-like prickles along them.

Rattan vine leaves are large and rounded at maturity. The plant can form dense mats and climb over shrubs and trees up to 66 feet high!

Crossvine

A climbing, woody swamp vine with pretty trumpet flowers. Crossvine climbs using disc-tipped tendrils that stick tightly to supports.

Crossvine boasts fragrant flowers but its sap contains calcium oxalate crystals that irritate the skin chemically. Handling the vine requires gloves.

Carolina Snailseed

A semi-woody, twining swamp vine with round leaves and greenish-white flowers. Stems exude a milky juice when cut or broken.

Carolina snailseed prefers consistently moist soils. The sap irritates skin and can cause painful blistering if gotten into eyes. Wear eye protection when around damaged vines.

Climbing Dogbane

A perennial herbaceous swamp vine with oppositely arranged, oval leaves. Vine stems are slightly woody and emit white latex sap when cut.

This caustic, milky sap can severely irritate and blister the skin and mucous membranes. Handle with gloves and care.

What to Do After Contact with Poisonous Vines

If skin contacts any poisonous vine, follow first aid guidelines:

• Carefully remove contaminated clothing and wash skin with soap and cold water.
• Apply rubbing alcohol, degreasing soap, or dishwashing liquid to the rash for 10 minutes to remove oils.
• Alleviate itching and weeping rashes using calamine lotion, colloidal oatmeal baths, baking soda compresses and antihistamines.
• For severe reactions, seek medical care for possible prescription steroid creams.
• To prevent infection in vine scratches, apply antibiotic ointment and keep clean until healed.

Desensitization Therapy

For highly allergic sufferers, allergy shots containing small amounts of urushiol may reduce sensitivity over time through gradually increased exposure.

Topical immunotherapies to induce tolerance are also under research.

How to Identify and Avoid Poisonous Vines

Key tips for identifying and steering clear of dangerous Georgia vines:

• Learn to identify common poisonous vines by leaf shape, flower color, and stem features.
• Notice thorns, fine hairs, berries, and exuded sap as warning signs.
• Wear protective clothing like long sleeves, pants, hats and gloves in vine-prone areas.
• Use thick boots and socks to prevent scratches and skin exposure.
• Stick to designated paths when hiking to avoid brushing vines.
• Do not burn, mow or weed whack unknown vines to prevent inhaling oils.
• After outdoor exposure, wash skin and clothing right away.
• Keep pets away from poisonous vines to prevent ingestion.
• Learn poisonous vine first aid in case of accidental contact.

When to Seek Medical Care

Consult a doctor promptly if rashes:

• Cover extensive parts of the body.
• Appear infected - oozing pus, increasing swelling.
• Cause severe pain or difficulty breathing.
• Persist more than 2-3 weeks without improvement.
• Occur along with fever, chills, body aches.

With vigilance and proper precautions, nature lovers can still enjoy Georgia's magnificent overgrown wilderness without risk from its poisonous vines.
