Biological Surveys & Resource Monitoring

We specialize in special status plant and animal surveys, habitat assessments, and construction monitoring. Our qualified team of permitted biologists and wetland scientists will map, model, or monitor any natural resource required to achieve environmental compliance.

With 18 USFWS 10 (a) (1) (A) Recovery Permits and experience surveying 68 additional sensitive species, a wide range of rare plants, and nesting birds, SummitWest can provide the biological surveys our clients most need. From wildlife and plant habitat assessments to riparian corridor mapping and wetland surveys, we specialize in all aspects of natural resource survey and monitoring. Through rapid analysis of our proprietary Species List Pro software and other sensitive status species databases, our team of biological desktop reviewers target surveys to the specific resource requirements of any given project site.

SummitWest biological monitors team with construction crews and supervisors to ensure environmental compliance while meeting project deadlines. Our keen attention to detail and current knowledge of species-specific resource permit requirements and mitigation measures smooths the way for our clients to tackle construction projects of all sizes and durations.
