Our mission is to assess, enhance, and restore aquatic habitats to benefit native species and the communities they support.
We assess, design, permit, construct, and monitor living shorelines, wetlands, vernal pools and stream valleys.
We delineate wetlands, assess vegetation, conduct water quality monitoring, and perform surveys for fish, SAV, oysters and other benthic organisms.
We design and deploy a variety of riparian and offshore habitat structures, including reef habitat for fish and oysters.
We prepare ecological construction cost estimates, conduct constructability reviews, provide construction management, and develop solutions to prevent delays.
We conduct bathymetric surveys, assess substrate conditions, and identify pollutant sources including marine debris.
Our licensed Captains with towing endorsements are available for scientific and educational excursions using our vessels or yours.
