Title: Economic Impacts of Aquatic Invasive Species


1
Economic Impacts of Aquatic Invasive Species
  • Oconto County presentation
  • Dale Mohr CNRED
  • UW-Extension
  • Originally Presented by Chad Cook Basin Educator
  • August 22nd 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
Eurasian Water-Milfoil
Common Reed
4
Invertebrates
Spiny Fishhook Waterfleas
Zebra Mussels
5
Vertebrates
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
  • Hydrilla
  • Water chestnut
  • Water hyacynth
  • Water lettuce

8
AIS Economic Impacts In U.S.
  • Ecological damage control costs 9 billion
    annually (Pimentel, 2003)
  • Fish - 5.4 billion
  • Zebra/Quagga Mussels - 1 billion
  • Plants - 500 million

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

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
  • 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
    conditions
  • Studies to be conducted in Vilas County and
    Waupaca Chain OLakes 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 WIs 120 million salmon and
    trout fishery

22
Uses of AIS Economic Data
  • Actual
  • Costs to control AIS
  • Water intake costs to control ZM
  • Riparians costs to control EWM
  • Cost data for impacts other than control are
    sparse
  • Fear-Based
  • Drives many AIS management decisions
  • Riparians fear reduction in property value
  • Local govts concerned about potential for
    reduced property tax revenue
  • Fears 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
  • Wisconsins Comprehensive AIS Management Plan
  • Prevent new introductions
  • Collaborate with user groups representing
    potential transport vectors
  • Limit the spread of established populations
  • Public awareness
  • Monitoring
  • Abate the harmful impacts from AIS
  • Develop control strategies

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