What are Invasive Species?
Introduced plants, animals and other
organisms that spread rapidly, outcompeting or
displacing natives and causing great harm to
the environment, the economy and people.
▪ Primarily spread by human activities
• Unintentionally
• Intentionally

Impacts of Invasives
▪ Pose a threat to wildlands, greenspaces, agriculture and home gardens
▪ Cause substantial economic burden on communities
▪ Eradication and control are costly and dangerous
Early detection reduces the need for pesticides, spares
the loss of tree canopy and helps protect clean water.

Which weeds are we targeting?
▪ The following three species are targeted for surveillance in 2021:
• Poison hemlock
• Tansy ragwort
• Garlic mustard
▪ These three species have been found in Clark County
▪ Each are either Class A or Class B weeds of concern
• Preventing new infestations and controlling existing infestations is the highest
priority
• Eradication of all Class A and control of Class B weeds is required by law
▪ Justin Collell, Clark County Weed Board will provide training and follow up support
