## Summary

Natural England, a public authority within the central government, initiated a procurement process titled "Baseline Aquatic Invertebrate Assemblage Survey of Strensall Common" aimed at conducting a comprehensive survey of aquatic invertebrates in designated sites throughout 2025. This project falls under the industry category of environmental services and is set in the United Kingdom, specifically within the UKE region. Initially active, the procurement was conducted via an open competition under the below-threshold method, offering a gross contract value of £16,200. Key submissions were required by 17 March 2025. However, the process was marked complete with a tender cancellation noted on 11 June 2025 due to unsecured funding.

This tender presented an opportunity for small and medium enterprises (SMEs) within the environmental services sector to engage in government contracts and bolster their portfolio by contributing to significant conservation efforts. Businesses proficient in environmental data collection and analysis, with an aptitude for conducting species and habitat assessment, would have been ideally suited to compete. Despite the cancellation, such opportunities illustrate the potential for growth through strategic participation in public tenders that align with eco-conservation initiatives.

## Notice

The aim of this contract is to undertake a comprehensive, aquatic invertebrate survey throughout 2025, on both the existing 'Strensall Common SSSI' and adjacent proposed SSSI sites: 'World's End Former Plantation', 'World's End' and 'Sandburn Wood'.
