This guidance documentpresents the basis for development of the weed control plan for the Timberline Project Lake Canal Habitat Buffer Zone,if weeds are deemed to be detrimental to plant
establishment success or eradication is required as per local or state regulations. As general guidance, it is recommended that no more than 10 percent of total plant cover be comprised
of weeds (“weed” definition in last paragraph) in the Lake Canal buffer zone at the end of each growing season. The project area will be evaluated twice per year for weed establishment,
once in mid-growing season and once at the end of each growing season for a period of three years following construction and planting. The completed plan will be submitted to the City
of Fort Collins Environmental Planner, as required for review and approval.
A Licensed Commercial Pesticide Applicator (LCPA) will prepare the weed control plan. All subsequent weed control activities will also be conducted by an LCPA. The plan will be in
the form of an Integrated Pest Management Plan (IPM) that will consider all methods of control that could be applicable to the project area. These methods include mechanical, chemical,
cultural, and biological techniques. Prior to plan preparation, a visit to the project area will be conducted at the end of the first growing season by the LCPA accompanied by representatives
of the City of Fort Collins and the Timberline development team, as appropriate. The objective of this site visit will beto assess site conditions, routes of access, weedy species present,
the proximity of wetlands to the proposed treatment areas, potential sources of run-on and run-off, and any other factors relevant to the weed control planning process. Site visits
will continue until the City of Fort Collins Environmental Planner approves habitat conditions within the natural habitat buffer zone.
Plant species to be considered as weeds and controlled and/or eradicated at this project site, as per City code, are those listed by the Larimer County Weed Control District and the
State of Colorado as noxious. Dominant weeds identified in the Lake Canal 50-foot setback area by the ECS Report field survey included: cheatgrass (Bromus tectorum) and leafy spurge
(Euphorbia esula). Leafy spurge is listed as noxious by Larimer County and the State of Colorado, as well as Canada thistle (Cirsium arvense), which was noted in other portions of the
project area. These three species will likely require methods of control, and other target weed species may be identified for control at the completion of project development and enhancement
measures employed in the Lake Canal buffer zone.
