Apathy – Perpetuation Economic risk Loss of tourism. CSU Extension says, “In CB the Ox-Eye daisy is crowding out the wildflowers they are famous for.” CoDeptAg says, “CB is a lost cause” Declining property values. Declining grazing acres. Increased fire danger – Brome grass. Escalating eradication costs.
Governmental Action Taken Federal Law – Subtitle E – Noxious Weed Control and Eradication. The Secretary of Agriculture is required, “to provide assistance to eligible weed management entities to control or eradicate noxious weeds on public and private lands”.
Government Actions Taken Colorado State – Title 35 The Colorado Noxious Weed Law 1990. Mandates the enforcement responsibility to county and local government. Law provides authority for assessment, notification, citation, access, remediation and the filing of tax liens on property.
Government Action Needed Gunnison County – Grossly under funded. No weed board, one interim agent. No intention of citing property owners or enforcing state law. Other Colorado counties are actively combating the problem. See LaPlata County (Durango), http://www.lpcweeds.org
Government Action Needed Cities - Crested Butte, Almont, and Crested Butte South currently contract with Gunnison County. No weed boards No enforcement. Lack of programs.
Establish – A Weed Agenda Understand the Risk. Know the Law. Assess the problem. Support Integrated Weed Management methods on city properties. Help Craft Ordinances. Help Educate land owners. Help Enforce and monitor compliance.
Real Estate Law The Colorado Real Estate Commission requires that the presence of weeds must be disclosed in writing and acknowledged by the buyer, prior to closing. This applies to commercial, residential and agricultural property.
More Bad Weeds Coming Knapweed – adapting to elevations Yellow Star Thistle – fatal to horses Curly Dock Perennial Sow Thistle – first seen in 06 Absinth Wormwood - Allelopathic

Herbicide Primer Personal concerns Toxicological - real Psychological - presumed Environmental concerns Impact on animals and desirables Persistence In ground In waterways
Herbicides (preferred) Milestone (cool weather broadleaf selective) Great on Chamomile Sterilizes seed Microbial breakdown Short half life Reduced rate (3-5 oz per acre) Toxicologically insignificant Environmentally (in new EPA “reduced risk” class)
Herbicides (preferred) Escort (cool weather broadleaf selective) Great on Toadflax (linaria bulgaris) Translocates via rhysomes Microbial breakdown Short half life Reduced rate (1.5 oz per acre) Toxicologically insignificant
Cultural Practice Grass Seeding with Slender Wheatgrass (San Luis) Sherman Big Bluegrass Winchester Idaho Fescue Lodorm Green Needlegrass Water to establish Reseed, reseed, reseed….
