Advancing Pollinator Habitat Monitoring through Remote Sensing on Nebraska Roadsides

To meet monitoring and reporting requirements under the Monarch Candidate Conservation Agreement with Assurances (CCAA), Nebraska Department of Transportation (NDOT) must collect consistent data on milkweed stem density and nectar-plant cover across extensive roadside networks. Current field-based approaches, though effective, are resource-intensive, limited in spatial coverage, and require a specialized level of biological expertise. NDOT needs a scalable and cost-effective remote sensing strategy that can meet CCAA requirements. Furthermore, NDOT must understand the costs and benefits to applying this technology in-house or via external contract, and how the products could be applied to offer NDOT versatile imagery and data outputs that can support broader environmental review needs, planning, and maintenance decisions.
