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 North Walney NNR. 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 dipwells in relation to the permanent vegetation plots are likely to be impacted by hydrological change, ## Lots (1) ### Lot 1: Untitled lot - **Lot id:** `1` - **Status:** complete - **CPV codes:** 71351920, 90711500 - **Delivery regions:** UK - **Delivery countries in notice:** GB - **Estimated Value:** £12,500 - **Contract Period:** 27/11/2025 to 16/03/2026 ## Awards & Winning Suppliers (1) - **Award:** 1 (cancelled) - Supplier(s): **Not published** - Date: 27/11/2025 ## Provenance and Official Sources - **Official Notice:** [Find a Tender notice](/out?url=https%3A%2F%2Fwww.find-tender.service.gov.uk%2FNotice%2F069903-2025) - **Last Source Update:** 2025-12-08T08:17:31.000Z - **This document generated:** 2026-10-29T19:15:25.092Z - **Machine API:** https://tenderline.uk/api/public/tenders/ocds-h6vhtk-05d77e
