2 Do not transplant non-native plants into lakes, streams, wetlands or storm water ponds intentionally or unintentionally!

3 Non-native plants can cause ecological, economic, and recreational problems Cathy Larson

4 Clayton & Michele Oslund Non-native animals can crowd out native species or disrupt the food web negatively impact recreational & sporting activities, & tourism Costly to manage Difficult to control

5 Non-native plants or animals Also known as exotic species, very difficult to control once established degrade the environment diminish recreational opportunities

6 Non-native plants or animals, Also known as exotic species, impact native species cost billions for control may be introduced intentionally or accidentally.

7 Invasive species introduced intentionally: improper disposal of fish or plants from water gardens or aquaria planting along shorelines to add beauty or stabilize the shore stocking fish for biological control of other species by natural resource professionals

8 Invasive species introduced unintentionally: Barbara Liukkonen Barbara Liukkonen as seeds carried by birds, blown by wind, carried by currents through flooding or storm water runoff as hitchhikers in plant acquisitions on boats or trailers, in live wells or bait buckets unwanted in water gardens in landscapes

10 Risk of Importing Aquatic Plants 2002 survey by University of Minnesota Horticulture Department Ordered aquatic plants from nurseries nationwide by phone & internet

11 Survey Results 92.5% of orders contained one or more hitchhikers ~ 90% included plants ~ 80% included animals (including 2 live fish!) 63% included algae, moss, or fungi 41% contained unordered seeds 8-10% of hitchhikers were prohibited species in Minnesota

12 Consumer Survey Water gardeners & shoreline property owners 77 surveys completed in Michigan & other states Asked these questions: - knowledge of plants, - sources of plants & information, and - willingness to pay for invasive-free plants. Water hyacinth Survey available at:

13 Consumers reported Most buy their plants locally, 17% exchange plants, 30% purchase animals, 80% recognize purple loosestrife, 6% know yellow heart, Many over-winter plants and animals outdoors.

14 Consumers reported 91% think aquatic invasive species pose a serious problem to lakes and streams. 40% spend $ annually on their water gardens. 90% said they would be willing to pay extra to avoid hitchhikers in plants they buy.

15 Never transplant non-native plants into lakes, streams, wetlands or storm water ponds intentionally or unintentionally!

16 Barbara Liukkonen Eleanor Burkett Barbara Liukkonen Examine new plants carefully Rinse floating plants to remove duckweed or other hitchhikers Pull hitchhikers from potted plants, or Remove plant from pot, rinse roots and re-pot to eliminate hitchhikers.

17 Eleanor Burkett Learn how invasive plants spread by seed, by rhizome, or by tiny plant fragments. rhizome Then, make appropriate plant choices.

18 Learn to recognize plants & fish that are potentially invasive in our zone Water hyacinth Flowering Rush Butomus umbellatus Yellow flag Iris Iris pseudacorusis Koi

19 Properly Dispose of Unwanted Plants or Fish Freeze or burn plants. Give fish to another water gardener, aquarium owner, school, library, nursing home, doctor s office, community center, hospital. Contact veterinarian for advice about humane disposal.

20 Robert Liukkonen Keep Non-Native Plants Contained in water gardens Water gardens separated from natural waters may contain non-native species. Design plan: no runoff or overflow Water gardens connected to natural waters planted with native plants or animals.

21 Robert Liukkonen Keep non-native plants contained in water gardens Water gardens separated from natural waters may contain non-native species. Water gardens connected to natural waters may NOT contain non-native plants or animals.

22 Regulations regarding the possession, transport or sale of non-native plants or animals NREPA 451 of 1994, Part 413: Restricted plants can be used in water gardens, but not released into natural waters! Prohibited plants are illegal to possess, buy, transport or sell destroy them! Flowering Rush Restricted Photo: Jane Herbert, MSU Extension
