The Urban Biotic Assessment Program is a group of taxa-specialists that conduct assessments of flora and fauna primarily associated with Illinois State Toll Highway Authority construction efforts. The group focuses on assessing the potential impacts of construction activities on biota, monitors wetland mitigation sites, and provides a source of data and information useful in conserving and managing the biota of the Chicago Region. The group works closely with the ISTHA in providing minimization, mitigation, and avoidance measures if impacts are present.
