NAISMA’s Minimum Mapping Standards

NAISMA’s minimum mapping standards for invasive weeds addressed the minimum base information necessary to compare and combine invasive weed maps across tribal, county, state/provincial, national, and even international borders.

Establishing minimum mapping standards increases the ability to share weed-mapping information so that the most basic information on infestations would be compatible between organizations and jurisdictions.

The Five Basic Elements of Invasive Species Inventories:

1. What species was documented?

2. Where on the landscape was this species documented?

3. How large was the area infested by the species documented?

4. When was the information on this species infestation documented?

5. Who collected the documentation of this species infestation?
