Predicting the behavior of invasive weeds

by Cambridge University Press

Is it possible to predict which nonnative plant species will become invasive weeds and when? According to research featured in the journal Invasive Plant Science and Management, the answer is “hopefully yes.” And those predictions can lead to more effective and cost-efficient weed management.

Researchers say invasive species generally follow a three-phase development curve – from lag to expansion to plateau. The length and rapidity of the expansion phase varies across species and determines how aggressively a plant spreads. Continue reading
