Prevention the first line of defense

• Do not plant invasives and educate plant buyers
• Monitor roads, ROWS, and streams
• Sanitize equipment and personnel
• Educate land users like hunters and hikers

CAUTION

• INVASIVE SPECIES CAN BE HAZARDOUS TO YOUR LAND!
• PREVENT THEIR TRANSPORT BY KEEPING EQUIPMENT
• CLEAN

Integrated Vegetation ManagementMethods for
Invasive Plants

• Prescribed Burning
• Mechanical
• Manual and Motor-Manual
• Biological Control
• Plastic Barriers and Mulch
• Herbicides

19
Prescribed Burning can.

• Deaden above-ground plant parts
• while most perennials will resprout
• Consume some plants, debris, and seeds
• improve access for other treatments
• Cause some remaining seeds to germinate to
  enhance reclamation
• Bare soil (and firelines) for reinvasion
• Firefighters/Burners may bring in invasive seeds

Hair Sheep Grazing

• 300 to 1000 per acre
• Sheep controlled by electric fence,
• shepherds, herding and Guard dogs.
• Less odor than cows and horses.
• Able to withstand extreme heat.
• Used in British Columbia and New
• Zealand to control forest vegetation and
• roadside vegetation in Australia and
• Denmark.

• Effective Herbicide Treatments
• To be successful with herbicides require
• the most effective herbicide,
• applied using the correct method, and
• applied during the best time period.
• Read and understand the herbicide label !!!
• Wear personal protective equipment !!!
• OR Contract a licensed professional applicator.
