Welcome to the i-Tree Pest Predictor Tool!

How do we know whether a non-native insect species will become invasive?

Many species arrive and never establish, but a few that do can have devastating impacts and threaten entire species of trees. This tool predicts the probability that a newly-arriving insect species will become a high impact invader on 50+ conifer species and 360+ hardwood species native to North America. Enter basic information on the insect of interest, including information on insect taxonomy, feeding guild, native range and native climate, and a list of tree hosts. The tool will then provide a list of probabilities for each relevant North American host tree.
