The NAISMA Mapping Data Standards provide a framework for consistently collecting and sharing invasive species data. By defining a core set of essential information, they help ensure data can be compared, combined, and used across organizations, jurisdictions, and data systems.
Originally developed by the North American Weed Management Association (NAWMA) and adopted in 2001 for invasive plants, the standards have since been updated and expanded through the ad hoc NAISMA Mapping Standards Committee. The 2018 revision broadened the standards to include all invasive species, including aquatic species and biological control, while incorporating modern data practices.
The standards establish a minimum set of essential information for documenting invasive species. This common framework allows datasets from different sources to be compared and combined while giving organizations flexibility to collect additional information based on their needs.
What species was documented?
Where on the landscape was it found?
How large was the infestation?
When was it documented?
Who collected the information?
The NAISMA Mapping Data Standards provide a common foundation for invasive species data collection and management. Organizations can incorporate the required fields into existing mapping systems or use NAISMA’s geodatabase template as a starting point.
Using consistent data fields makes it easier to:
The standards define the minimum information needed for compatibility without requiring organizations to use the same software or limiting the additional information they may choose to collect.
Whether you are developing a new invasive species mapping program or updating an existing data system, the NAISMA Mapping Data Standards can provide a foundation for consistent data collection.
Organizations can adopt the required fields within their existing systems or use the NAISMA Geodatabase Template to get started. For additional guidance, the Mapping Standards Short Course walks through the standards and demonstrates how they can be applied in real-world invasive species mapping.
