Roseville, MN Invasive Plant Rules: Prohibited Species (2026)

The core rule is section 1011.03(a)(4)d of the Roseville City Code: no new landscaping shall contain plant materials that are listed on the state department of agriculture noxious weed list or the state department of natural resources invasive terrestrial plants list. It sits in the plant material standards beside the zone tolerance rule in subsection (a)(4)c, which requires selection under the USDA plant hardiness zone map, and the diversity rule that not more than 30 percent of the required number of trees may be composed of a single species.

The definitions in section 1001.07 add a local species list: an invasive tree is any tree species not native to the state or its regional ecosystem that can spread into non-cultivated soil, and the code states that invasive tree species include Norway maple, black locust, Amur maple, Siberian elm, and buckthorn. A separate duty applies to every private landowner under section 705.09(1): no person shall plant or allow to be planted on any privately owned property any tree, shrub or herbaceous plant listed in the public tree master plan as prohibited.

Section 705.09(5) adds that plants deemed a health or safety hazard by the city forester must be treated or removed, and section 705.12 requires the city forester to serve a written order to correct the condition. Under the tree preservation rules in section 1011.04(e)(4)a, a tree identified as an invasive species that must be removed can be classified as exempt when a degreed forester or certified arborist certifies it.
