Take Permit from the USFWS. No states recognize the use of “bait away” as an
efective minimization measure. Bait away stations create artiicial means to attract
a species away from potential development, but studies have found these measures
largely unsuccessful in helping with conservation and expose ABB to greater
predation risks at the bait away station.
3. Mitigate
Mitigation typically refers to ofsite conservation easements, which are protected
in perpetuity to provide suitable habitats for ABB. For example, Oklahoma has
designated Conservation Priority Areas, where ofsite mitigation is encouraged.
Similar areas designated for conservation easements haven’t been developed in other
states at this time.
Wind project proponents should determine the amount of potentially suitable
habitats that cannot be avoided, determine a density of ABB within those habitats,
and mitigate those areas impacted accordingly.
An Industry Conservation Plan developed for the oil and gas industry in
Oklahoma has identiied various mitigation ratios depending on the nature of
the impact (permanent or temporary), and the location of the impact (within
Conservation Priority Areas, previously established mitigation lands, or elsewhere).
hese mitigation ratios may be applicable to future wind projects, but must be
developed through coordination with the USFWS and the appropriate state wildlife
management agency.
As a project proceeds within the potential range of ABB, permitted biologists
can assist wind power developers with surveys, Biological Assessments, or Habitat
Conservation Plans to comply with the Endangered Species Act. As with any
proposed project, it’s imperative to contact and involve the local USFWS Ecological
Services Field Oice and the respective state wildlife agency early in the planning
process to avoid unnecessary project delays or expenses.
