Client requirements: Whether a client requires ecosystem-based compatible land use plans, climate adaptation studies, resource conservation analyses, mitigation and banking strategies, or conservation-based remediation and reuse plans for surplus military/federal real property, Marstel-Day utilizes its analytical rigor and inherent environmental ethic to achieve those goals. Through our analyses, we help clients identify, influence, and adapt to changing land uses, resources constraints, ecosystem services markets, and climate change impacts.

Client projects and analyses are enhanced through our use of strategic, pro-active outreach and engagement with external stakeholders, assisting clients to develop win-win partnership solutions that address the local impacts of land use issues, such as sea level rise, loss and protection of critical habitat, and protection or enhancement of valuable ecosystem services.
