Interpretive Summary: Invasive species are estimated to cost the U.S. economy $138 billion annually. Much of this loss is due to invasive weeds that adversely impact croplands, forests, urban areas, and natural plant communities. Biological processes and characteristics are the most important factors in a plant's ability to establish, spread and persist. This manuscript provides an overview of the most important processes and characteristics essential to develop effective control strategies for invasive weeds based on a weed's most vulnerable stage of growth.

Technical Abstract: Biological processes and characteristics are important factors in the success of pathways of invasive weed introduction, spread, and establishment. These biological traits include reproduction, dispersal, phenology, physiology, protection from herbivores, tolerance to environmental extremes, and inter-specific interactions. Measures and methods to prevent dispersal, establishment, and persistence of non-native invasive weeds include knowledge of the most vulnerable growth stages, management strategies, maintenance of weed-free areas, and sanitation of vehicles for transportation, equipment, animals, and other modes of dispersal.
