1 Economic Impacts of Aquatic Invasive Species Oconto County presentation Dale Mohr CNRED UW-Extension Originally Presented by Chad Cook Basin Educator August 22 nd 2006

2 What are Invasive Species?   Definition: Non-native plants and animals that may cause economic, environmental, or recreational harm or affect human health.   Invasive because: No natural predators, parasites, etc. Often aggressive, prolific, and mature early (See Handouts and posters)

3 Plants Purple Loosestrife Eurasian Water-Milfoil Common Reed

4 Invertebrates Spiny & Fishhook Waterfleas Rusty Crayfish Zebra Mussels

5 Vertebrates White Perch Round Goby Alewife Sea Lamprey

6 Others  Quagga Mussels  Common Carp  Rainbow Smelt  Threespine Stickleback  Reed Canary Grass  Curly-Leaf Pondweed  Flowering Rush  ‘Cylindro’  And More

7 Future Threats?  Asian Carp  Snakehead  Three-spine stickleback  New Zealand mud snail  Numerous Plants: HydrillaHydrilla Water chestnutWater chestnut Water hyacynthWater hyacynth Water lettuceWater lettuce

8 AIS Economic Impacts In U.S.  Ecological damage & control costs: $9 billion annually (Pimentel, 2003) Fish - $5.4 billionFish - $5.4 billion Zebra/Quagga Mussels - $1 billionZebra/Quagga Mussels - $1 billion Plants - $500 millionPlants - $500 million

9 Zebra Mussels  Damage & control costs $1 billion annually (Pimentel et al., 2005)$1 billion annually (Pimentel et al., 2005) $5 billion annually (Lovell and Stone, 2005)$5 billion annually (Lovell and Stone, 2005)  Municipal and industrial water intake costs Small: $20,000 annuallySmall: $20,000 annually Large: $350,000 - $400,000 annually (Ruetter)Large: $350,000 - $400,000 annually (Ruetter)  Power plant costs (USGS) Hydropower: $83,000 annuallyHydropower: $83,000 annually Fossil fuel: $145,000 annuallyFossil fuel: $145,000 annually Nuclear: $822,000 annuallyNuclear: $822,000 annually

10 Sea Lamprey  Chemical Control - $13 million annually in Great Lakes  Release of sterile males  Barrier construction  Lake trout stocking program  Losses of other Lake Michigan sport and commercial fishes = $26 million/yr = $26 million/yr

11 Ruffe  Losses to native fishery: $500,000 annually (Lovell and Stone, 2005)

12 Eurasian Water-Milfoil & Curly-Leaf Pondweed  $400 - $600/ac to treat EWM/CLP in WI  $1.1 million spent for chemical treatment on 2,300 ac in 2003 in WI (DNR)

13 Purple Loosestrife  Spreading at 285,000 ac/yr  Losses and control: $45 million annually in U.S. (Pimentel et al., 2005)

14 Secondary Impacts – Difficult to measure  Nuisance Control  Property Values  Tourism  Fisheries  Health

15 Nuisance Algae  $4 million annually at each power plant on Lake Michigan on nuisance algae control (pers. comm. WE Energies)

16 Property Value Impacts  High potential from nuisance conditions created by AIS  Many costs born by riparians  Demand for lake front property remains strong

17 Property Value Impacts  Correlation between property value and water quality - clarity (Krysel et al., 2003)  Residential property value quantified as being at risk at approximately 10% due to EWM infestation (Deamud et al., 2004)  Infestation by hydrilla reduced property value by at least 10% (TVA, 1994 in Bell & Bonn, 2004) = Willingness to pay= Willingness to pay Complete control raised property values 17 – 35%Complete control raised property values 17 – 35%  No apparent impact of AIS on real estate market in Door County or Shawano Lake area (personal communication) Major effect is putting up with nuisance conditionsMajor effect is putting up with nuisance conditions  Studies to be conducted in Vilas County and Waupaca Chain O’Lakes in 2006

18 Tourism Impacts  Proliferation of EWM/CLP  Cladophora on beaches

19 Tourism Impacts  Value of day at the beach in Chicago estimated at $35/person (Shaikh, 2005)

20 Fishery Impacts  Lake Michigan fishery is comprised of many exotic species

21 Fishery Impacts  Zebra mussels are changing the Lake Michigan food chain  Potential to impact WI’s $120 million salmon and trout fishery

22 Uses of AIS Economic Data  Actual Costs to control AISCosts to control AIS oWater intake costs to control ZM oRiparians’ costs to control EWM Cost data for impacts other than control are sparseCost data for impacts other than control are sparse  Fear-Based Drives many AIS management decisionsDrives many AIS management decisions oRiparians fear reduction in property value oLocal gov’ts concerned about potential for reduced property tax revenue Fears can be realFears can be real

23 Summary  AIS cost estimates often vary widely, either due to actual differences in AIS impacts, or because of inconsistent estimation methodology  Many impacts have not been estimated or are difficult to economically assess  Economic fear drives many AIS management decisions  AIS cost estimates need to consider valuations other than just control costs – e.g., human health values, use values, existence values, or valuations of ecosystem services

24 AIS Management Messages Wisconsin’s Comprehensive AIS Management Plan 1.Prevent new introductions Collaborate with user groups representing potential transport vectors Collaborate with user groups representing potential transport vectors 2.Limit the spread of established populations Public awareness Public awareness Monitoring Monitoring 3.Abate the harmful impacts from AIS Develop control strategies Develop control strategies

25 Effective AIS Management/Control Programs  Clean Boats, Clean Waters Contact Laura Felda, UWEX/DNRContact Laura Felda, UWEX/DNR  AIS Grants Contact DNR regional lakes/AIS grant coordinatorContact DNR regional lakes/AIS grant coordinator  Purple loosestrife bio-control Contact Brock Woods, DNRContact Brock Woods, DNR  Citizen Monitoring Network Contact Laura Herman, UWEXContact Laura Herman, UWEX  Fish hatchery/bait collector HACCP plans Contact Phil Moy, Sea GrantContact Phil Moy, Sea Grant  Sea lamprey control
