DMS holds a Class A-General Engineering Contractor License to perform restoration projects from the design phase through completion, monitoring construction progress and providing environmental compliance with state and federal agencies. Wetland enhancement is performed by bringing land elevations to suitable heights for seasonal and tidal wetlands and is achieved by mechanical or hydraulic fill methods. Dixon Marine has also performed vernal pool construction, revegetation programs, native habitat studies, and monitoring on local species of birds, fish and wildlife to provide the best support on restoring land to its natural state with minimal impact to local and native species. The Montezuma Wetlands Restoration Project is an example of an ongoing restoration effort near Grizzly Island in the Suisun Bay that DMS was a part of for over four years.
DMS's scientists have conducted dozens of ecological and environmental studies including:
Fishes and aquatic invertebrates(planktonic and benthic) outside and within the San Francisco Estuary system, including the Sacramento-San Joaquin Delta
Field sampling and experimental laboratory studies as well as various dissections to characterize species of concern
Predator/prey and food web interactions
Zoo-plankton vertical migrations
Fish distributions and evaluations of environmental damage to aquatic fish and fauna
Benthic and fishery surveys using fish trawls, fluke and plankton nets for collection and analysis
