Watch List weed species are species for which the Commissioner, in consultation with the state noxious weed advisory committee, local governments, and other interested parties, has determined to pose a potential threat to the agricultural productivity and environmental values of the lands of the state. The Watch List is intended to serve advisory and educational purposes only. Its purpose is to encourage the identification and reporting of these species to the Commissioner in order to facilitate the collection of information to assist the Commissioner in determining which species should be designated as noxious weeds. The Commissioner may place a plant species on the Watch List if any of the following are present:
6.2.1.	The plant species is not known to occur in the state, but its noxious characteristics are recognized by another state or states in the region.

6.2.3.	The plant species with suspected noxious qualities as determined by the use of a plant assessment process is present in the state but its distribution and effect on agricultural and natural lands is undetermined at this time.
6.3.	Once the noxious characteristics and distribution of plant species on the Watch List are better known, the Commissioner, in consultation with the state noxious weed advisory committee, local governments, and other interested parties, may act to place a species on List A or List B, or may remove it from the Watch List.

Factual and Policy Issues
The factual and policy issues encountered in the proposal of these amendments to the rules are as follows:
1.	The current rules pertaining to the administration and enforcement of the Colorado Noxious Weed Act state that the Commissioner will develop and implement state noxious weed management plans for selected List A and List B species.
3.	State noxious weed management plans are necessary in order to coordinate appropriate actions at the private, local, state, and federal levels that will halt the continued spread of these List A and List B species.
4.	The proposed plans have been developed in consultation with the state noxious weed advisory committee, local governments, and other interested parties. The proposed plans include weed management plans for List B species corn chamomile (Anthemis arvensis), mayweed chamomile (Anthemis cotula), bouncingbet (Saponaria officinalis), common tansy (Tanacetum vulgare) and wild caraway (Carum carvi).  The management plans for the chamomiles are combined due to the similarity of the species, distribution, and management measures.
5.	The change to Rule 4.7.13 A and F is due in order to implement Custer County’s request that it be removed from the list of counties exempted from the requirement of eliminating leafy spurge (Euphorbia esula) from within its borders.
6.	The change to Rule 6.1 is to add garlic mustard (Alliaria petiolata) and yellow flag iris (Iris pseadocorus) to the Watch List, given their current unknown noxious qualities and the need for closer statewide observation.
