Biological and Cultural Resources

UltraSystems understands that biological resource compliance is a critical aspect of successful project development and a key element of the planning process.

We employ a diverse team of talented and experienced biologists, regulatory specialists and support staff. They are knowledgeable and thoroughly familiar with California habitats, flora, fauna, restoration and survey methodologies and protocols, as well as special-status species’ natural history and conservation issues as they relate to California. Our biologists are experienced in major fieldwork throughout the many environments of California, from urban areas to remote, isolated habitats.

Our cultural resources professionals are recognized as qualified historians, archaeologists and paleontologists by the federal government, state agencies (including Caltrans) and numerous local jurisdictions. We are experienced in many facets of cultural resource projects, including surveys, site testing and evaluation, Native American consultation, historic site recordation and research, mitigation programs, construction monitoring, cultural evaluations of geophysical data, evaluations for National Register eligibility and paleontological studies.
