NJ like many states in the US has a growing problem with invasive insects and animals. Invasive species like the Spotted Lantern Fly can be very devastating to crops and hardwood trees. Information about other invasive insects of concern can be found here. Aquatic invasive species can outcompete native species becoming a significant threat. A number of non-native animals can be found in New Jersey.
The NJDEP does have an Invasive Species Council and the NJ Invasive Species Strike Team is actively involved in monitoring invasive species and working to eradicate them.
