In this activity, students research real life examples of invasive species. Students research how the species entered the US, its effects, and possible management options. In this way, students can see how invasive species negatively affect native ecosystems.
In part B of the activity, students read about Chestnut Blight. This gives them an opportunity to see the effects of an invasive species at its most catastrophic.
While this is geared towards PA, it could be used in any eastern state.
