Wetland Ecology & Management
Versar has provided wetland ecology and management services since 1969 in diverse ecosystems for private and public sector clients on projects throughout the US and its territories. Our services range from wetland delineations and functional assessments to development and implementation of complex compensatory mitigation plans. We offer our clients the best scientific and project management skills to address their environmental issues. Our wetland ecology and management services include:
- Wetland and stream identification and mapping
- Regulatory coordination
- Jurisdictional determinations
- Clean Water Act permitting
- Compensatory mitigation design and implementation
- Wetland restoration
- Functional assessments
- Wetland and stream monitoring
- Wetland studies supporting NEPA or other planning requirements
Versar employs trained and certified professional wetland scientists, wetland ecologists, botanists, and wildlife biologists. Our background and experience allows us to use current technologies such as highly accurate global positioning system to collect spatial and attribute data for seamless incorporation into a geographic information system We have routinely used LiDAR, aerial photography, LANDSAT, and other remote sensing data to assist with wetland identification and classification. Versar wetland consultants have expertise in tidal marshes, emergent and forested swamps, vernal pools, and arid land wetlands.
Versar has conducted wetland ecology and management studies for numerous Departments of Defense, the Department of Transportation, and other federal facilities; water districts; oil and gas pipelines; and various commercial clients. For example, Versar completed wetlands delineations on 10,000 acres at Camp Lejeune, North Carolina. The habitats our scientists delineated included technically challenging estuarine and freshwater tidal marshes; bottomland hardwood forests; pocosins; pine plantations; and developed areas.
We also conducted a delineation of all wetlands and streams for 8,369 acres at Marine Corps Air Station Cherry Point. As a result, Versar wetland scientists, GIS specialists, and project management mapped 1,437 acres of wetlands and nearly 30 miles of stream channels. We secured a jurisdictional determination from the USACE Washington Office in December 2013.
Versar performed wetland health assessments to assist base natural resource managers in monitoring 686 acres of wetlands in Texas and New Mexico. We used the EPA Targeted/Tiered approach, along with historic aerial photography; current high-resolution digital imagery; shapefiles; and Cowardin classification of wetlands to define a gradient of impairment. This method allowed Versar biologists to identify and characterize wetland sites likely to be affected by anthropogenic and environmental stressors.
Versar scientists developed a mitigation plan to compensate for unavoidable impacts to wetlands from a proposed Navy Facility. Onsite investigations included detailed topographic mapping, wetland delineation, mapping, a 1.5-year shallow groundwater well study, and soil quality testing. The mitigation plan developed nine credits at standard compensation ratios.
