About Us

Cooper Ecological Monitoring, Inc. (EIN 72-1598095) was founded in 2005 by Daniel S. Cooper, formerly with Audubon California, and author of "Important Bird Areas of California" (2004).

Often working with a network of partner biologists, including Jen Mongolo of Map Ecology, we bring extensive experience in designing and conducting habitat assessments and species inventories (especially birds and local plants), and employ the latest ecological principles and techniques.

What We Do

Environmental Compliance (CEQA/NEPA) and Monitoring

We help write and review biological sections of environmental impact reports, and advise clients on avoiding impacts to protected species and natural resources during development and restoration projects.

Biological Assessments

A lifelong birder and outdoor enthusiast, I have been studying southern California’s flora and fauna professionally for more than 10 years, and tailor survey methods to meet both our client's needs and the characteristics of each site. While most of our work focuses on birds, we work with a network of colleagues with a diverse range of specialized knowledge.

Protocol Surveys for the California Gnatcatcher and other special-status bird species

Need a gnatcatcher survey done? Think there's a rare species on your property? Don't take the risk—work with experts first.

Long-Term Research Projects

Horned Lizard and Griffith Park

Griffith Park

After a major fire in 4,000-acre Griffith Park, Cooper Ecological Monitoring was selected by the City of Los Angeles to advise the Department of Recreation and Parks on the post-fire recovery of the site. Since then, we have worked with neighborhood groups and advocacy organizations to continue ecological research in the park.

Cinnamon Teal Ducks in Ballona Wetlands

Ballona Wetlands

With Robb Hamilton of Hamilton Biological, we worked with the Los Angeles Co. Dept. of Beaches and Harbors to update and pass the Marina del Rey Local Coastal Program, and continue to monitor nesting herons and other waterbirds here. From 2003-2013, we conducted quarterly bird surveys and avifaunal analysis of nearby Ballona Freshwater Marsh and the Playa Vista Riparian Corridor for E Read and Associates, Inc., and mapped birds across the entire Ballona Wetlands for the Bay Foundation from 2009-2012.

Coastal Cactus Wren

Coastal Cactus Wren Survey

In spring 2009, we worked with the Nature Conservancy to organize, train and supervise a team of more than 20 volunteers to conduct the first-ever comprehensive survey of this rare bird in Los Angeles County. In 2012, we worked with the Western Foundation for Vertebrate Zoology and the California Department of Fish and Wildlife to launch a similar project in Ventura County.

birds in malibu lagoon

Malibu Lagoon Restoration

Starting in 2012, we began conducting nesting bird and post-restoration monitoring at the lagoon, which will continue through 2017.

Santa Monica Mountains Coastal Zone

Santa Monica Mountains

Working with Robb Hamilton of Hamilton Biological, Cooper co-authored a Conservation Analysis of the Santa Monica Mountains Coastal Zone, which served as the scientific underpinning for the recently-updated Local Coastal Program for the region. He now works with clients, including private equestrian facilities and other landowners, to bring facilities up to compliance, and to balance development with long-term preservation of the region’s natural resources.
