---++Definition Framework matrix (proposed by Kevin Thiele)
|
||
|
|
|
||
|
|
*Proposal* - we will provide a picklist of a large number of terms that people use in various databases to describe alien invasives (a shortlist is in *Table A*). These terms will include some we don't like, and the terms will not be mutually exclusive. However, we will also provide a more atomised set of terms using which providers must define what they mean by the terms they use. The term-defining concepts and terms are in *Table B* below. See also SampleDefinitions.
