WALKING SHADOW ECOLOGY LLC specializes in ecological assessment, environmental monitoring, and habitat restoration services grounded in field-based scientific methodology. The firm applies rigorous ecological survey techniques, including species inventory, wetland delineation, and environmental impact analysis, to support compliance with NEPA, ESA, and Clean Water Act requirements. Their technical expertise centers on terrestrial and aquatic ecosystem characterization, invasive species management, and restoration planning using native plant ecology and soil stabilization practices. What distinguishes the company is its place-based approach, integrating local ecological knowledge with geospatial data and long-term monitoring protocols to deliver defensible, science-driven outcomes for sensitive landscapes. Award history is not available to infer specific agency relationships, and no recent contract awards have been recorded to confirm direct client engagements. Consequently, no patterns of agency collaboration can be documented from the provided data. The primary NAICS code, 541620, reflects environmental consulting services, indicating a focus on applied ecological science rather than engineering or construction. In practice, this means the firm delivers technical assessments, environmental permitting support, and conservation planning—often in support of land management, transportation, or energy infrastructure projects requiring ecological due diligence. The company positions itself as a niche provider of field-intensive ecological services in regions with high conservation value. WALKING SHADOW ECOLOGY LLC is a small, locally based entity structured as a 2L (Limited Liability Company) and headquartered in Gardiner, Montana. The firm holds no federal certifications, and its market presence is defined by geographic proximity to federally managed lands in the Northern Rockies. Its operational footprint is anchored in field ecology services across public and private lands, leveraging regional expertise to support environmental compliance and stewardship initiatives.

The selected prime provider will be responsible for the end-to-end delivery of the project, including CMS platform configuration, responsive design, information architecture, content migration from existing systems, hosting, and ongoing support.

Solicitation # Environmental-Trust_RFP_FY-2027_Emergency-Plan-Update-Environmental-Services_1014.pdf
The Confederated Tribes of the Colville Reservation is seeking professional services for emergency management planning and environmental engineering and consulting, with a combined maximum budget of $289,497. The emergency management portion, capped at $150,000, involves updating the 2014 Comprehensive Emergency Management Plan, developing Emergency Support Functions and hazard-specific annexes, creating the first Tribal Threat and Hazard Identification and Risk Assessment and Continuity of Operations Plan, and facilitating coordination workshops and a tabletop exercise. The environmental services portion, capped at $139,497, includes biannual groundwater monitoring and testing at the Nespelem Post and Pole site and the removal and disposal of hazardous materials at the Nespelem Recycle Center. The contract runs through September 30, 2027, with services provided on an as-needed basis and renewable annually. Key requirements include mandatory monthly progress reports, the submission of all final plans in editable and PDF formats, and the maintenance of insurance against injuries or property damages. Because the total value exceeds $100,000, a performance bond is strictly required. Selection is based on a criteria evaluation process weighing qualifications, specialized experience, proposal responsiveness, and TERO status, rather than lowest cost alone. TERO fees are not included in the scope of work budget and will be determined separately by the Tribal Employment Rights Office.
