Effects on bat species and habitats resulting from renewable energy (i.e., wind and solar) and linear infrastructure (i.e., transmission and pipelines) developments are of specific interest. Studies and analyses supporting projects involving Indiana bats and northern long-eared bats, baseline acoustical monitoring, and Habitat Conservation Plans are prominent.


  • Field investigations and ecological assessments (including study design and implementation, data collection and statistical analysis, interpretation, conclusions and recommendations).

  • Wildlife-related environmental impacts analysis, regulatory compliance/permitting, and client and agency contacts
  • Project development (i.e., work scopes, proposals and costs).


  • A Bachelor’s or Master’s degree in applicable field (bat biology/ecology, biological science, natural resources or wildlife management, or a closely related discipline).
  • Strong technical skills in field ecology methods and acoustic data analysis.
  • A minimum of 2-3 years of professional experience in wildlife ecology and management.
  • A minimum of 2 years of technical experience in the evaluation of land use or resource development effects on wildlife species and habitats, especially bats.
