Environmental Litigation Support

For two decades, Great Ecology has provided scientific consulting services for both plaintiff and defense environmental litigation across the United States.
As ecologists, we bring a holistic understanding of ecosystems that allows us to comprehensively assess and address environmental injuries and provide ecological remedies.
Our experience includes landmark cases like Deepwater Horizon, 20+ Natural Resource Damage (NRD) cases, small site-specific litigation, and everything in between. We maintain an expert team of subject matter experts with PhDs, Masters, and support staff that consider key issues like climate change and environmental justice throughout our services.


Our Clients:




Great Ecology's scientists have served as both testifying and non-testifying/consulting experts for defense and plaintiffs legal counsel. We leverage our experience to support clients with informed perspectives from both sides of the table. When needed, our experts conduct in depth data collection and/or analyses and interpretation to:
• Understand the environmental context
• Quantify damages
• Convey facts to a non-scientific audience
• Develop effective remedies

Service Spotlight: NRDA



Natural Resource Damage Assessment (NRDA) provides a process to determine the appropriate form and amount of restoration needed to offset environmental impacts to habitats, wildlife, and communities from oil spills, contamination, and other unplanned injuries. NRDA models, assessments, and remedies require highly trained scientists with extensive experience - a skill Great Ecology has honed over 20 years.


What Defines Injury?

Ecosystems are highly complex and driven by a suite of ecological services that fall into four fundamental categories:
• Water Cycle
• Soil Cycle
• Energy Cycle
• Biological Cycle
These foundational services help drive a multitude of other regulating and provisioning services that collectively generate an array of benefits such as habitat creation, maintenance of populations and biodiversity, and adaption in the face of climate change (among many others). Benefactors of these services include not just humans but also wildlife and the ecosystems themselves.
When conducting a NRDA, practitioners assess contaminated sites to determine the level of injury across ecological services, quantify the amount of lost service, and derive appropriate damage estimates for use in legal proceedings

Great Ecology's Holistic Assessment

The traditional NRDA process uses a product-based approach that views injury through a singular lens focused on human stakeholders (communities) by quantifying lost value of products such as timber, raw materials, and land. As ecologists, Great Ecology understands that this method of analysis is incomplete since ecosystems have greater value than just the products they create.
As NRDA practitioners, we integrate this perspective into our NRDA process by assessing injury holistically by evaluating not just the products of an ecosystem, but also the processes that generate these products through a lens that considers human, wildlife, and habitat stakeholders. This enables us to generate comprehensive reports that provide a more accurate accounting of lost ecosystem value.
