ONYX RANCH SVRA PROJECT
The US Geological Survey is conducting market research to determine contractor availability for advanced statistical modeling and assistance at Onyx Ranch SVRA, with capability statements due September 4, 2026. No set-aside applies. NAICS 541620 (Environmental Consulting Services) and PSC B510 (Special Studies/Analysis—Environmental Assessments) govern this procurement, with a $19.0 million size standard.
The contractor must demonstrate advanced statistical expertise evidenced by peer-reviewed publications within the last 15 years and proficiency in general linear models, mixed effects models, k-means clustering, spatial analysis using ArcGIS, multivariate regression tree analyses, discriminant analysis, and nonparametric statistics. Work is performed at Onyx Ranch State Vehicle Recreation Area in the western Mojave Desert, California.
Deliverables include publication-quality maps and figures identifying desert tortoise locations relative to roads and park boundaries; perennial vegetation cluster analysis resulting in 4–6 distinct associations with distribution maps; distribution maps of invasive annual grasses and Sahara mustard; analysis and mapping of western Joshua tree distribution; spatial analysis of human disturbances including vehicle tracks, livestock grazing impacts, and campsites; and integrated models identifying the most important variables across all datasets. Initial drafts of vegetation, invasive species, and Joshua tree analyses are due 60 days after award, followed by a 15-day government review period. Model drafts are due 90 days after award with 30 days for finalization. The contractor will be compensated on an hourly rate basis. All deliverables become government property with potential USGS publication. Capability statements must be submitted electronically to yangzhi_deng@ios.doi.gov by 0800 PST on September 4, 2026.

The US Geological Survey Office of Acquisitions and Grants seeks advanced statistical modeling and assistance for the Onyx Ranch State Vehicle Recreation Area project, with quotations due September 17, 2026 at 1500 PST and questions due September 10, 2026. This is a combined synopsis/solicitation for commercial items under FAR Part 12, procured as an RFQ (140G0326Q0218) with no small business set-aside.
Place of performance is the vendor's facility, with delivery to the USGS Reno Field Station, Reno, Nevada. The estimated period of performance runs October 1, 2026 through February 28, 2027.
The Statement of Work requires a master's degree with statistical training and peer-reviewed publications demonstrating expertise in statistical modeling techniques including general linear models, mixed effects models, multivariate regression tree analyses, discriminant analysis, nonparametric statistics, and ANOVA. GIS mapping capability must produce publication-quality maps. Primary tasks include analyzing desert tortoise distribution across 289 randomly-placed hectares, conducting k-means clustering on perennial vegetation to identify 4–6 clusters, mapping non-native invasive species, analyzing Western Joshua tree distribution, spatial analysis of human disturbances (vehicle tracks, grazing impacts, campsites, trash, shooting evidence), and developing statistical models identifying the most important variables across datasets. Initial drafts for tasks 1–4 are due within 60 days of award, followed by 15 days for government review; model drafts are due at 90 days with 30 days for finalization. The contractor works under technical guidance of a USGS Principal Investigator and is compensated at hourly rate only. All deliverables become government property; no copyright claims are permitted.
The NAICS code is 541620, Environmental Consulting Services, with a $19.0 million threshold. Quotations must include a signed SF 18 form with line-item pricing, firm fixed-price quote, technical submission with work plan and resumes, listings of prior relevant contracts with two or more professional references, and SAM UEI. Award will be made using the tradeoff method. Amendment 0001 posted September 11 answers submitted questions with no additional questions permitted; contractors must acknowledge receipt of the amendment by the September 17 deadline.
