If cost is an issue I suggest identifying each distinct patch of an invasive

species by a dot with the size of the patch in the metadata. This is much 

easier than a two dimensional shape. For example, in the table for Little

Paint Branch Park, Japanese Barberry, Berberis thunbergii, site A is

described as a patch 10 feet x 20 feet. At Swann Park, English Ivy, 

Hedera helix, site A is described as a 0.2 acre patch. 

 

We completely remove a patch of invasive species (i.e., walk in all

directions and note that there are no more target plants) and note percent 

return from roots, seed sources, or missed individuals, next year. Cheers.

For Switzerland, you can ask the "centre du réseau suisse de floristique"

CRSF to have maps.
