Loveland, CO Invasive Plant Rules: Prohibited Species (2026)

01(C), Prohibited Plant List, bars three categories from the city: plants identified as noxious, invasive, or prohibited in Loveland by the United States or the State of Colorado; nonfunctional turfgrass or artificial turfgrass on commercial, industrial, institutional, common-interest-community, right-of-way, parkway, parking-lot, median, or transportation-corridor land; and any plant the City's Director of Development Services adds to a maintained prohibited-plants list. Any of these found on a property must be removed during development or redevelopment. 06(A), Invasive Species, Disease, and Pests, extends the removal duty past the construction phase: all invasive species must be removed from property proposed for development, substantial improvement, or redevelopment, and developed property must be kept free of invasive species on an ongoing basis.

Subsection B of that same section separately requires trees threatened by epidemic disease, such as Dutch Elm Disease, or insect infestation, such as Mountain Pine Beetle, to be treated to control the spread of the problem organism. 01(B) lets the Director maintain and modify an approved plant list, weighing invasiveness alongside climate zone, growth habits, hardiness, and drought tolerance when deciding what can be planted, and the Director can approve non-listed plantings for a specific development to test their suitability. These provisions were most recently amended by Ordinance 6819, effective March 17, 2026, so they reflect current UDC text rather than a superseded version.
