## Summary

The procurement process initiated by Natural England concerns the "Development of a network of hydrological monitoring across the Long Term Monitoring Network: Lower Derwent Valley." This falls under the services category with a focus on oceanography and hydrology services, as well as environmental monitoring. The buyer, Natural England, is a public authority within the central government, based in London. The project is located in the East Riding of Yorkshire. Although initially in the tender stage, the process was later cancelled due to unsuitable proposals. Initially, the submission deadline for quotations was the 24th of November 2025, with the contract period scheduled from the 27th of November 2025 to the 16th of March 2026.

This tender opportunity was set to create growth prospects for businesses involved in hydrological and environmental monitoring services, especially those capable of providing quality services at competitive rates. Small and medium-sized enterprises (SMEs) were considered suitable for this open competition, given the below-threshold value of the contract, set at £15,000 gross. For businesses capable of developing conceptual hydrological models and advising on field deployments of monitoring equipment, this tender could have provided a meaningful expansion platform into public sector environmental projects.

## Notice

Natural England's Long Term Monitoring Network (LTMN) started collecting data in 2010, aiming to identify if and how ecosystems are changing and, where relevant, to attribute that change to large-scale ecosystem pressures. Data is collected across 37 sites, most of which are National Nature Reserves. Alongside other data collection, there are approximately 50 permanent vegetation plots and 5 permanent soil plots at each site. Hydrological change is considered to be a potentially significant driver of ecosystem change on all LTMN water -dependent sites, but it is currently poorly understood. This contact requires a conceptual hydrological model to be produced for the Lower Derwent Valley NNR, located in the east Riding of Yorkshire This may be done as a desk based exercise using existing information, or through a site visit if appropriate. From this we require advice on suitable locations for a network of dip wells in relation to the permanent vegetation plots are likely to be impacted by hydrological change,
