Each species account includes key identification characteristics, growth form, habitats invaded, control methods, similar native and non-native plant species, and current status of the plant in Maine.

For orders received by June 30, the guide price is $18, which includes 5.5-percent sales tax and shipping and handling. To order, send a check — made out to Treasurer, State of Maine — to MNAP, 177 State House Station, Augusta, ME 04333. For credit-card orders, call 287-2801.
