Why help preserve Wisconsin threatened and endangered plants?
• Promote biodiversity – a natural mix of many different species which provide for a healthy environment.
• Protect historic plants and habitats for future generations
• Preserve plants important to butterflies and other insects
• Preserve plants which may be future sources for medicines, treatments, etc.
• Help maintain a varied and attractive landscape

What you can do• Contact your local DNR Transportation Liaison or
Regional Ecologist to find out more• Mark right-of-ways once a species is identified
– Local citizens and groups may be available to help • Protect by timed mowing or no-mow area• Alert crews doing brushing, digging, spraying, and utility
work• Comply with administrative rule (NR27) and state
statute – It is illegal to remove, transport, carry away, cut, root up, sever,
injure or destroy a wild plant on the Wisconsin Endangered and Threatened Species List on public lands (which includes public right-of-ways). Section 29.604, Wis. Stats.
