What are invasive species? Management & your role in it. Introduction to the invaders Reporting invasions Vector issues
invasive species is an alien species whose introduction does or is likely to cause economic or environmental harm or harm to human health
Biological invaders destroy habitats or out-compete native plants and animals.
At least 30 new potential biological invaders enter the US every day.
Invasive species cost Americans about $143 billion per year.
Why should you care?
What makes a plant invasive?
Lack normal environmental constraints Fast growth and reproduction Highly adaptable a wide range of conditions Often can transform their environment Often encouraged by disturbance Dominance = less biodiversity
How do we manage invasive plants?
Prevention Quarantine before introduction Monitoring & mapping Chemical treatment (herbicides) Biological controls (biocontrol) Cultural treatment (hand pulling, cutting, etc.)
