3Laws
- MBTA Migratory Bird Treaty Act (1917)
- Protects all 830 native species of birds
- No incidental take
- BGEPA Bald and Golden Eagle Protection Act
- Extra protection of eagles
- ESA Endangered Species Act
- Take negotiable through act beforehand
4History of the FWS Guidelines
- 2001 Presidents Energy bill
- May 2002 DOIs Renewable Energy on Public Lands
Initiative FWS asked to develop siting
guidelines
- July 2002 FWS working group wrote draft in 4
days
- 2002/2003 finalized, reviewed internally
- 2003 July 2005 FWS distributes for comment
- Next Steps
- 25 letters received FWS revising, final form
uncertain.
- More regional workshops likely.
5Guidelines Basics
- An endorsement of wind energy, but
- Wind turbines kill birds and bats
- Developments can fragment habitat
- Bird deaths violate Federal laws
- Cumulative mortality is a concern
- Guidelines are voluntary interim
- Recommendations for development, design,
operation
- plus 8 appendices
- Site ranking protocol
- Recommendations for pre-and post-construction
surveys
- Recommended research
- More
6Recommendations for Site Development
- Avoid
- E T species
- migration pathways or concentration areas, e.g.
wetlands, leks, etc.
- flyways between roosting and feeding areas
- areas with frequent fog, low visibility weather
- bat hibernacula, breeding or maternity colonies,
migratory corridors
- landscapes that attract raptors
- prairie grouse leks
- Array turbines clumped or parallel to bird
movements
- Dont fragment habitat
- Be sensitive to area- structure-sensitive
species (prairie grouse)
- Build in degraded rather than healthy or native
habitat
- Minimize roads/infrastructure
- Habitat restoration plan
- Reduce carrion remove carcasses
7 and for Design and Operation
- Tubular towers no guy wires for met. towers
- Lighting recommendations
- Adjust tower height
- Underground powerlines
- Monitor for 3 yrs. minimum
- Upgrade, retrofit, and relocate older turbines
8Appendix 1 Evaluating Sites
- The Potential Impact Index (PII) rank sites the
Montana way
- Form an evaluation team
- Select reference sites (highest impact) in WRAs
- Evaluate potential development sites score land
features and wildlife resources
- Sum, normalize, and rank against reference sites
9PII score sheets
Species Occurrence and Status
Ecological Attractiveness
10Sum, Normalize, Rank, and Compare to Reference
Sites
Ranks are guide to developers High rank doesnt p
reclude development Low rank doesnt preclude pre
-construction surveys
11followed by Pre-construction Surveys
Focus on species or regions identified in PII
analysis
- Verify/investigate
- Species occurrence and status
- Influence of physical features
- Other site-specific questions, e.g. weather
USFWS
12 and Post-construction Surveys
- Relate to pre-construction survey,
Before-After-Control-Impact (BACI) study design
- Testing new designs to minimize collisions is
encouraged

- Definitions
- Applicable wildlife laws
- Research needs
- Consultation and spp. Evaluation under ESA
- Siting on FWS easements in Region 6
- Impacts of Wind Turbines on Wildlife
- References
14Major Concerns
- Where birds aggregate -- hotspots
- Raptor migration/concentration areas
- Grouse leks
- Coastal Gulf, East, and West
- Off-shore?
15Sooty Shearwater
16Additional Papers
- GAO Report
- WIND POWER Impacts on Wildlife and Government
Responsibilities for Regulating Development and
Protecting Wildlife -- September 2005
- http//www.gao.gov/new.items/d05906.pdf
National Academy of Sciences Due December 2006
Environmental impacts of wind-energy projects --
focusing on Mid-Atlantic Highlands
Develop a framework for evaluating effects
Identify major areas of research and development
17Additional Publications
- Methods and Metrics for Determining or Monitoring
Potential Impacts on Birds NWCC 1999
- Methods and Metrics document for night-flying
migrants is being produced NWCC
18Bottom Line -- avoid potential conflicts
- Engage USFWS and State agencies early
- For ET information
- For migratory bird information
- For other potential wildlife impacts
19Sources of Bird Mortality per year Estimates
- Buildings -- millions
- Cats -- millions
- Cars hundreds of thousands to millions
- Collisions with wires lots and lots
- Seabird by-catch tens of thousands?
- Electrocutions -- lots
- Communication Towers hundreds of thousands
- Wind ca. 2 birds/turbine (30,000/yr)
- Altamont Pass 100 GOEA, 200 BUOW, 100s of
other raptors
20Comments thus farhttp//www.nationalwind.org/upda
te/040318-wildlife.pdf
- Siting Guidelines Developed solely by Feds
- Do FWS Field Offices know that they are
voluntary?
- Site comparison protocol impractical
- What is a reference site?
- Time required for assessment
- Site ranking means sharing site information
- Number of comparison sites not specified
- Team of agency/academic biologists FOIA-able
info.
- Project size not weighted in risk
- Time to gather information could be too long
- Eco-regional planning ecosystem context of
site
- 3 year pre-construction survey impractical
- Pre-construction survey techniques over-the-top
