MARSH & ASSOCIATES LLC

Marsh & Associates LLC specializes in environmental consulting services focused on aquatic ecosystem restoration, native fish monitoring, and invasive species management in federal waterways. Their technical expertise includes field-based ecological assessments, nonnative fish removal protocols, and habitat-specific monitoring systems for sensitive species such as razorback sucker and Gila River basin native fishes. They apply rigorous scientific methodologies to support compliance with the Endangered Species Act and federal water resource management directives, often integrating field data collection, telemetry, and ecological modeling to inform adaptive management strategies. A notable distinction is their ability to execute complex, on-the-ground field operations in remote riverine environments, combining ecological science with practical field engineering solutions. The contractor maintains a consistent relationship with the Department of the Interior, delivering ecological monitoring and resource protection services across multiple basin systems, including Lake Mohave and the Gila River watershed. Their work for this agency centers on conservation biology, fisheries management, and habitat intervention projects aligned with U.S. Fish and Wildlife Service priorities. They have also supported the General Services Administration under a Federal Supply Schedule, indicating established procurement pathways for environmental consulting services across federal agencies. Their primary industry focus is environmental consulting services under NAICS 541620, with supplementary experience in scientific and technical consulting (541690) and specialized equipment procurement for underwater communications (334220). This positions them as a niche provider of field-ready ecological solutions rather than purely analytical consulting, blending ecological science with operational deployment in federal natural resource contexts. Marsh & Associates LLC is a small, privately held entity based in Tempe, Arizona, with no federal certifications on record. Their geographic presence and operational focus are centered on the arid southwestern U.S., where they deliver targeted environmental services to federal land and water management agencies.
