Assessing and maintaining the health of aquatic ecosystems is of paramount importance because water is the basis of life. Herrera’s aquatic ecologists assess algae, aquatic plants, invertebrates, and fish populations in lakes, streams, rivers, and estuaries. We determine if your lake has toxic algae or invasive species and offer solutions to address the problem. We conduct underwater surveys, prepare plans for managing invasive plants and protecting rare plants, assess impacts of water pollution on sensitive aquatic organisms, assess aquatic habitat conditions, design habitat restoration, obtain grants to fund management activities, and conduct eelgrass and forage fish surveys in Puget Sound for permit compliance.
