Spatial abundance information is a critical component of invasive plant risk assessment. While spatial occurrence data provide important information about potential establishment, abundance data are necessary to understand invasive species’ populations, which ultimately drive environmental and economic impacts.
Early detection helps resource managers identify and report new invasive species, especially for cryptic species and those in very low abundance, to better assess risks to natural areas. Tracking the establishment and spread of existing and new invasive species is critical to effectively manage invasive species.

Risk maps summarizing landscape suitability of novel areas for invading species can be valuable tools for preventing species’ invasions or controlling their spread, but methods employed for development of such maps remain variable and unstandardized.
Invasives cause problems for millions of the world's most vulnerable people and threaten the economic growth supported by sustainable development.
Invasive species can harm the values for which land is conserved. Natural lands are not fully protected unless they also are managed for the features that first motivated preservation. Invasive species can change community structure, composition, and ecosystem processes on these lands in ways that may not be anticipated or desirable.

The majority of non-native plants do not cause any harm, and thus are not invasive. Managers often determine which plants are invasive and which pose the highest risk for their area by conducting risk assessments. Risk assessments are generally conducted by a formalized group using an agreed-upon method.
