Catherine Anne Schnurrenberger

Catherine Anne Schnurrenberger, operating as C.S. Ecological Surveys and Assessments, is a woman-owned small business sole proprietorship based in Truckee, California, that provides ecological field surveys, rangeland inventory data collection, and environmental assessments to federal land management agencies as a prime contractor under Total Small Business set-asides. The vendor competes exclusively under set-asides; all fourteen recent awards carry Total Small Business designations or no set-aside language, with work concentrated in the Western states—primarily California and Nevada.

The vendor's concrete capability footprint centers on grazing land inventories, special-status plant surveys, and on-site ecological data collection for federal rangeland management and conservation programs. Representative work includes a $1.67 million Total Small Business purchase order awarded April 16, 2026, by the Department of Agriculture's Natural Resources Conservation Service to conduct annual data collection across 276 points on Southern California grazing lands (Inyo, Riverside, San Bernardino counties) through January 2031, with work performed in Truckee, California; a $248 thousand Total Small Business BPA call from the Bureau of Land Management under the Land Management Integrated Resources National BPA for special-status plant surveys in Nevada (March 2026); and a $132 thousand call under the same LMIR BPA from USDA for FY25 special-status plant surveys in Nevada (April 2025). Personnel requirements across these awards specify team leaders with range management degrees and minimum one-year rangeland inventory experience, plus crew members with at least two years of undergraduate training in biological or earth sciences. The vendor's NAICS concentration runs across All Other Professional, Scientific, and Technical Services (six awards), Support Activities for Forestry (four awards), and Environmental Consulting Services (three awards).

Customer concentration is heavily skewed toward a single anchor vehicle. The Department of Agriculture Forest Service Washington Office Acquisitions accounts for $50 million (94% of combined potential value) through a single-award $50 million BPA for land management integrated resources services awarded March 17, 2023, and running through March 6, 2033. The Department of Agriculture's Natural Resources Conservation Service Western Region places seven awards totaling $2.6 million, and the Department of the Interior's Bureau of Land Management Nevada Region places three awards totaling $459 thousand. Across the vendor's recent portfolio, combined dollars obligated total only $1.1 million (2% of the $53.1 million combined potential value), indicating most of these awards remain unexercised task orders or multi-year IDCs with future demand signals. One award—the $248 thousand BLM special-status plant survey—completes within the next twenty-four months and represents recompete exposure. Activity has been sparse and episodic: one award in 2022, two in 2023, two in 2024, one in 2025, and two in 2026 to date. The vendor holds no subcontract work and operates 100% as a prime contractor.
