2) whose introduction causes or is likely to cause economic or environmental harm or harm to human health.

Explanation

Wanted Establishment in the Wild

Escape from Captive Areas

Chance of Economic Gain

Human Enjoyment

Exotic Pets

5 Most Common Ways they get into our Country

Displace native species

Reduce native wildlife habitat

Reduce forest health and productivity

Alter ecosystem processes

4 Ways they Negatively Affect Our Environment

Definitions1 Reintroduced Species in PAWhy, When, How the species was

Reintroduced

Reintroduced/Extirpated Species

Reintroduced Species- a release of species from captivity or other areas where the species can survive back into the wild

Extirpated Species- a species that no longer exists in the wild in a certain area but can be found elsewhere

Definitions

Rocky Mountain Elk-They released 177 Elk from Wyoming and
