Nonnative species that harm or have the potential to cause harm to the environment, economy, or human health are known as invasive species. Propagule pressure may be the most important factor in establishment success of nonnative species of various taxa in a variety of ecosystems worldwide, and strong evidence is emerging that propagule pressure determines both the scale of invasion extent and impact. In a limited way, the US government is applying a “propagule pressure approach” in a variety of prevention policy contexts aimed at minimizing the impact of harmful organisms. However, there are also readily apparent opportunities for enacting propagule pressure-based measures to fill current gaps in invasive species prevention and control at national, state, and local levels. An explicit focus on propagule pressure-based policies could substantially increase the effectiveness of US efforts to prevent the introduction of invasive species through by intentional and unintentional introductions.

Managing Multiple Vectors for Marine Invasions in an Increasingly Connected World (2013, background): “…effective means to reduce the future ecological and economic costs of NIS is to prevent their introductions by managing the many vectors that deliver them, rather than by focusing efforts on the management of individual species or even individual vectors (Ruiz and Carlton 2003, Reaser et al. 2008).”
