AQUATIC ECOSYSTEMS and MARINE RESOURCE ASSESSMENTS

Dial Cordy and Associates Inc. has been involved in most types of aquatic ecosystem assessment, and has played active roles in restoration design and impact analysis. Field efforts have been used to create ecological baseline reports and to guide planning for development or restoration activities. Our aquatic work is complemented by DC&A's Marine Division in large rivers and estuaries, and by DC&A's land management group when projects are set within larger terrestrial ecosystems. DC&A's strengths include technical capabilities in the field and the ability to develop creative solutions to assist clients with difficult projects. DC&A also has in-house laboratory facilities for specimen identification and sample processing.
