Invasive Plant Species Assessment

The Invasive Plant Species Assessment of public lands was conducted to determine the extent, type, and management options for exotic trees, vines, and other plants that threaten our urban forests and landscapes. Invasive plant species management techniques (PDF) for various invasive species are included in the report appendix. Take a look at the Charlottesville Vegetative Debris Management Plan (PDF) for more details.

What are invasive species?

Invasive species as defined by USA executive order 131112 are:

  1. non-native (or alien) to the ecosystem under consideration and,
  2. whose introduction causes or is likely to cause economic or environmental harm or harm to human health.

In general, we can think of non-native plants/animals that are not originally from the Southeastern USA, and have negative impacts on our native flora, fauna, and economy.

In Charlottesville we are seeing a prolific increase in invasive plants because our city is undergoing a great deal disturbance brought on by development.  

Why we the people and our local critters don’t like invasive vegetation:

  1. Invasive vegetation has a negative impact on our native flora and fauna
  2. Outcompeting native plants – making it difficult for native plants to grow
  3. Invasive vegetation reduces biodiversity and tree canopy
  4. Not nourishing local wildlife that depend on native vegetation
  5. Invasive vines climb trees and kill them by strangling them or adding so much weight that trees break
  6. Altering fire and hydrological cycles
  7. Established populations act as tremendous seed sources spreading the problem far and wide
