Who we are

Margaret Lang is an environmental engineer specializing in environmental fluid mechanics, hydraulic modeling, fish passage through hydraulic structures, and hydrology. She is a full professor in the Environmental Resources Engineering Department at Humboldt State University.

Steve Railsback is an environmental engineer and ecologist specializing in modeling ecological systems, individual-based ecological modeling, and assessment of instream flow needs for river fish and ecosystems. He is an adjunct professor in the Mathematics Department and Environmental Systems Graduate program at Humboldt State University and previously was on the research staff at Oak Ridge National Laboratory.

Our associates include talented scientists and professionals with whom we contract as needed for projects. Associates have included software developers, environmental engineers, ecologists, decision scientists, and field technicians.

What we do

Our mission at LRA is to provide quality basic and applied environmental research with high quality, focus, and productivity. Unlike many environmental consultants, we are experienced and skilled at research: developing and testing hypotheses and technologies to answer basic questions and solve management problems. Unlike many university researchers, we can often dedicate substantial time and resources to our clients’ specific needs.

Much of our work is in river management and freshwater fish, but we have also worked on a variety of other problems such as forestry effects on owls, river management effects on amphibians and birds, effects of regulations on fishing fleets, and land use effects on birds and the pest control services they provide.

Our clients have included American Bird Conservancy, Argonne National Laboratory, the U.S. Bureau of Reclamation, the Electric Power Research Institute, the U.S. Forest Service’s Pacific Southwest Research Station, the U.S. Geological Survey’s Forest & Rangeland Ecosystem Science Center, the Ocean Conservancy, Pacific Gas & Electric, Save the Redwoods League, and a variety of universities and consulting firms in the U.S. and abroad.
