Ecological surveys are conducted to identify the presence of threatened or endangered species, establish habitat quality for impact analysis, map community types and locations, wetland permitting, NEPA documentation, monitoring created wetland effectiveness, and establish potential chemical impacts at hazardous waste sites. Adverse effects to threatened or endangered species are addressed through surveys, agency coordination, and mitigation. Current or future impacts to biota are required and addressed at potential development and hazardous waste sites which may be affected by development or remediation actions. In accordance with state and federal regulations, these impacts are addressed by conducting an ecological risk assessment at the hazardous waste sites.
Aquatic and terrestrial biological surveys are conducted, as appropriate. Aquatic macroinvertebrates, including mussels and fish surveys are conducted using methods such as seine, dip net, “noodling”, and backpack and boat electroshock. Plant, amphibian, reptile, bird, and mammal surveys, as well as terrestrial invertebrate surveys when appropriate, are performed using a variety of methods and protocols. Habitat types are identified and mapped.
As necessary, L&A has a team of endangered species associates which we call on as is necessary for a project. The most commonly used experts address endangered species groups such as bats, mussels, butterflies and moths, and snakes.
