Predictive value of plant functional types in determining future high-impact weeds

摘要

The plant functional type (PFT) method may help improve predictions of the impacts of invasive species. We present a subset of a large trait set from invasive species from south-east Queensland that we are using to test the applicability of the PFT method. Biomass accumulation and allocation did not differ between high- and low-impact species across the 53 species we sampled. We conclude that high- and low-impact species cannot be differentiated solely by growth-related traits.
