Full Breakdown

010 targets the movement of plants rather than their mere presence in a yard: what is unlawful is to sell, offer for sale, expose for sale, give, trade, or transport for use in planting any propagative part of a listed species. Because giving and trading are covered alongside selling, handing cuttings over a fence is treated the same as a nursery sale. The list runs 20 entries, opening with bird cherry or Mayday trees (Prunus padus) and reed canary grass (Phalaris arundinacea) and including itadori or Japanese knotweed (Fallopia japonica), which is among the list's three knotweed species, along with spotted knapweed.

020(a), the state's noxious weed list, and every plant species quarantined from entry to Alaska by the Alaska Department of Natural Resources, so Anchorage's ban tracks state action automatically. Movement stays legal when the purpose is destruction, removal from the municipality, or approved research, which keeps eradication and disposal work lawful. If the list has not been updated, the department must revisit it every five years.

Violations & Fines

Selling, giving, trading, or transporting a listed species for planting draws a $250 fine per violation under AMC 15.90.020.

Frequently Asked Questions

Can I still dig out and dispose of Japanese knotweed on my Anchorage property?
Yes. The ban exempts moving listed species for destruction, removal from the municipality, or approved research, so removal and disposal work stays legal.
Does the ban cover giving plants away for free?
Yes. AMC 15.90.010 reaches selling, offering or exposing for sale, giving, trading, and transporting for planting, so a free start of a listed species violates it as much as a sale does.
What is the penalty for selling a banned plant in Anchorage?
A $250 fine per violation, under AMC 15.90.020.
Which plants are on the list?
20 listed species, including bird cherry (Mayday) trees, reed canary grass, three knotweed species, and spotted knapweed, plus everything on the state noxious weed list in 11 AAC 34.020(a) and every species quarantined by the Alaska Department of Natural Resources.
