At Meristem, our goal is to listen first, and making your concerns our top priority. We work with you as an extension of your team. Meristem is a collaborative initiative that seeks first to understand. We recognize that each and every project is a unique dream, circumstance, or endeavor that has had a tremendous amount of thought and hours dedicated to navigating the next steps that include big decisions. Many of these decisions are stymied by layers of constraints and challenges that seem nebulous, vague and many times overwhelming. Meristem looks to ease the burden of ambiguity by clearly articulating the current regulatory policies and then working with you to create a path forward that is both economically and environmentally fulfilling.

Marc Woernle
Principal Ecologist
Marc is our Principal Ecologist. He started out his career in Florida in the mid 90's monitoring large mitigation sites for the Phosphate, Rock, Sand, & Titanium Mining Industries. His work in Florida is extensive and covers most of the state. For several years he surveyed and relocated Gopher Tortoises, trapped Florida Mice, monitored Burrowing Owls, Red-Cockaded Woodpeckers, Bald Eagles and completed globally rare plant studies in its Florida Scrub, Pine Flatwoods, Cypress Swamps and Tidal Wetlands. Moving to Indiana gave him the opportunity to work with the Military on rare plant and stream studies in the deserts of Arizona, wetland permitting in coastal non-tidal wetlands in Maryland, including other projects in various states. He has worked with some of the largest energy companies in the USA and the largest homebuilders in the USA completing various types of wetland and endangered species assessments, permitting, mitigation designs, and integrating natural solutions to complex environmental constraints. His aptitude for native plant identification and ecology allowed him to integrate wetland treatment systems in California, Maine, and elsewhere. He was the lead Field Director for Two Sections of I-69 overseeing rare and endangered fish, crayfish, mussel, bat, and neo-tropical migratory songbird surveys. He was also the Field Director for multiple large pipeline projects requiring endangered species, wetland, & stream assessments in Texas, Oklahoma, Illinois, Ohio, & West Virginia. He has extensive knowledge of flora throughout the United States and has expertise in natural resource permitting pertaining to Industrial Business Complexes, International Airports, and Residential Communities.
