Mission: prevent the spread

• f emerging invasive species

across New Jersey

• NJ’s first Cooperative Invasive

Species Management Area (CISMA)

• Formed in 2008 as “Central Jersey

Invasive Species Strike Team”

NEW JERSEY INVASIVE SPECIES S T R I K E T E A M

What are we protecting?

NEW JERSEY HAS 2,000 NATIVE PLANTS!

62 Land Mammals 28 Marine Mammals 44 Reptiles 35 Amphibians 85 Freshwater Fish 336 Marine Fish 180 Dragonflies and Damselflies 151 Butterflies

. . .

An invasive species

• Non-native and grows densely to the exclusion of other plants
• Reduces biodiversity
• Interrupts the natural functions of an ecosystem

and The Ugly! The Bad... The Good...

"I now suspect that just as a deer herd lives in mortal fear of its wolves, so does a mountain live in mortal fear of its

• deer. And perhaps with better cause,

for while a buck pulled down by wolves can be replaced in two or three years, a range pulled down by too many deer may fail of replacement in as many decades.”

• Aldo Leopold

Damage to Forest Health

• Loss of native shrubs & herbs
• Loss of tree seedlings to replace fallen canopy trees
• Loss of native fauna dependent upon native flora
• Increases amount of invasive plants that are unpalatable to deer

Chemical Control: Foliar Spray (FS)

Technique

• Plants < 4’ to avoid spraying over head
• Wet all leaves with herbicide
• Glyphosate: 1%-5% active ingredient (Ex. Rodoe)
• Triclopyr (amine): 1%-5% active ingredient (Ex. Garlon 3)
• Use surfactant to increase sticking power
• Use dye to track treatment

Pros

• Effective control
• Cost effective

Cons

• Sensitive to weather conditions
• Potential for drift

When Annuals: Before seed set each growing season Deciduous: Growing season Evergreen: Year round (reduced non-target spraying)

Chemical Control: Cut Stump (CS)

Technique

• Cut all stems horizontally and directly

(6” or less) above the ground, apply herbicide immediately on all exposed stumps

• Glyphosate: 20-25% active ingredient (ex. Rodeo)
• Tryclopyr (ester): 15-20% active ingredient (ex.

Garlon 4 Ultra)

• Herbicide dye for tracking treatment

Pros

• Effective control
• Targeted control

Cons

• Time consuming
• Stem removal required

When Year round except for when sap is rising (typically early spring). Fall is a highly effective time.

Chemical Control: Basal Bark (BB)

Technique

• Apply continuous band of directly to the bark
• Band should be 8-12 inches, depending on thickness of tree

trunk

• Avoid bottom 1-2 inches of trunk (prevents leaching into soil)
• Do not spray until dripping
• Triclopyr (ester): 20% active ingredient (exGarlon 4 Ultra)

Pros

• Effective control
• Targeted control
• Cost effective

Cons

• Some oil diluents are not

environmentally friendly

• Not as effective on larger or

thick-barked trees When Year round Avoid standing snow
