AbstractThis map set displays information about noxious weed locations as determined by the 2005 Noxious Weed Survey. The survey is conducted annually by the Noxious Weed Control Program in the Water & Land Resources Division.
For this map set, noxious weeds are very loosely classified by color into four habitat categories: - Aquatic—blue
- Urban/Park—green
- Open Space—red
- Pasture—orange
Users can display the noxious weed information in two ways: - Display only the four most widespread noxious weeds: Giant Hogweed, Purple Loosestrife, Spotted Knapweed, and Tansy Ragwort.
- Display all of the more than forty noxious weed species found in the survey. With this option, users may view all of the weed symbols in the standard iMAP legend frame, or launch a separate floating legend window (by clicking on the"All Noxious Weeds" layer name in the iMAP interface).
Possible Uses:- Find out how many noxious weed locations were surveyed in your city or near your favorite natural feature, such as a wetland, lake, or stream.
- Learn about individual weed species: use iMAP's "Identify" tool to click on a weed symbol on the map, and then click on the corresponding species link when it appears below the map.
