Outsmart Species

Below is the master list of all the plants and insects included in the Outsmart app.

We have assigned a "reporting priority" to each species to indicate the associated level of risk. These labels help our team respond to major threats quickly and effectively, but remember: Every species is there for a reason.

Regardless of the risk level, it is important to report any potential invader. You can read more about these reporting priorities at the end of the list.

Reporting Priorities

Established: These plants have already invaded Massachusetts and are steadily gaining ground. Don't be dismayed - it's still important to report them! The more data we have on the whereabouts of established invasive plants, the better we will understand how their distributions are changing over time. This kind of information can help shed light on how climate change is affecting native ecoystems.  

Early detection: These plants may already exist in some parts of the state, but they are not yet widespread. There is still potential to control these invasives, but it is critical that we catch them early. That means every report makes a big difference!

Insects: Bugs, pests, mini-beasts. You got it: These are invasive insects, which are typically much more destructive than invasive plants. They pose considerable threats, and if found, eradication measures may be taken to stop them.
