Wetlands & Streams › 

Our Certified Senior Ecologist works with our field biologists and ecologists to survey and identify a broad range of plants and animals, both terrestrial and aquatic. We strive to offer unparalleled ecological consulting services; it is our goal to provide clients with the most complete and accurate ecological information, allowing project managers and planners to make better-informed and more sustainable land use decisions.

Ecological Surveys › 

Our team researches a site and characterizes it to identify exposure routes (from contaminant sources to ecological receptors), and looks for potential evidence of stress within exposed plant and animal communities. Through this process, we strive to generate sufficient data to provide a “reality check” to balance the inherently conservative assumptions of the standard risk assessment process.

Ecological Risk Assessments› 

Our goal is to promote ecological and environmental literacy by providing educators and students with relevant, firsthand experiences in applied ecology. This comes in the form of summer camp activities, after-school programs, community workshops, teacher training, curriculum development, or site planning.
