Natural Resource Management

ESA team members share a common goal of protecting, enhancing, and restoring the natural environment—from the headwaters to the coast—and creating resilient landscapes and recreational destinations that benefit our communities. Our experts pioneered some of the earliest wetland restoration planning efforts and published tidal wetland restoration design guidelines that are now widely used by restoration practitioners throughout the U.S.

Claremont and North Quincy Forest Resiliency Projects Heritage Survey

The Plumas National Forest’s Claremont and North Quincy Forest Resiliency Projects aim to reduce hazardous fuels, restore habitat, treat invasive plants, and reduce high-intensity fire risk to Quincy and other communities in American Valley.

Quincy, California

Dutch Slough Wetland Restoration

This 1,200-acre project is the first large-scale tidal restoration project in the Sacramento-San Joaquin Delta, designed within an adaptive management framework to test different restoration approaches that will inform future restoration efforts in the region.

Contra Costa County, California

Client: California State Coastal Conservancy

Riverbend South Restoration

This project improves recreational river access and restores sensitive riparian areas along over a quarter mile of the Deschutes River at Riverbend Park.

Bend, Oregon

Client: Upper Deschutes Watershed Council (UDWC) and Bend Park & Recreation District (BPRD)

Sebastian Inlet Coastal Engineering and Biological Support

In 1919, the Florida State Legislature established the Sebastian Inlet District with the mission of preserving the channel connecting the Indian River Lagoon to the Atlantic Ocean.

San Geronimo Creek Restoration Project

More than 1,300 feet of San Geronimo Creek restoration was designed and implemented to improve fish passage and reconnect flood habitat to improve access to spawning and rearing habitat for endangered Central California Coast Coho Salmon.

Client: Salmon Protection and Watershed Network (SPAWN)

Our interdisciplinary team of ecologists, hydrologists, biologists, geomorphologists, engineers, water quality specialists, and landscape architects work together to create practical, ecosystem-based designs. We blend rigorous scientific analysis with practical engineering solutions.

We offer a full range of restoration and conservation services to help clients solve mitigation challenges—from initial planning, feasibility studies, and conceptual design through permits, environmental compliance, and final design. We provide bid documents, construction phase services, and post-project monitoring to implement our designs, which allow natural habitats to reclaim their role in a healthy ecosystem.

Through stewardship of land and other natural resources, we preserve and conserve these assets while accommodating planned growth and development.
