Wetlands and Coastal Ecology
Ecological Risk Assessment
Our staff is experienced in and passionate about performing protective ecological risk assessments. We calculate health risk to animal populations based on contaminant concentrations in the environment and specifics of the animals' feeding habits, home range use and body weight.
Our ecological risk assessments have included studies of mammals, birds, invertebrates, fish and shellfish and their exposures to carcinogenic and non-carcinogenic hydrocarbons, PAHs and metals. Our risk assessment results provide a numerical value for the potential hazard to each animal population studied.
We will provide you, as our client, with an ecological risk assessment that is based on protection and conservation of animal populations.
Our expertise in species biomonitoring includes population studies of freshwater fish, crawfish, blue crabs, wetland bird species and vegetation surveys. We perform assessments of species size and weight, population abundance, tissue contaminant accumulation, and vegetation richness and biodiversity. We collect aquatic species for laboratory analyses following State and Federal protocols. Our field studies are focused in freshwater and intermediate wetland settings.
We use a rapid wetlands assessment method to gauge the services and functions provided by wetlands ecosystems, as supported by EPA guidance. The assessment checklist measures critical wetland structure and function components that provide the ecosystem services expected of functioning wetlands. Our wetlands assessment measures services provided by wetlands including: surface water storage, habitat for fish/waterfowl/wildlife, diverse plant habitat, nutrient transformation, retention of sediments, element transformation, erosion control and accretion of soils.
Coastal Use Permitting
Our team has extensive experience working on projects in coastal environments, including working closely with all regulators for projects. We obtain all required project reviews and permits from regulators like the Army Corps of Engineers, State Coastal Regulators, regional authorities and local governments. This includes overhead and cross-section plans of work to be performed, detailed work plan for the application, nesting bird surveys, and preliminary and post-work vegetation analysis. Our experience allows us to obtain coastal use permits in an efficient and timely manner.
