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, ## CPV classification Oceanography and hydrology services Environmental monitoring other than for construction Source Find a Tender (UK) · Notice ocds-h6vhtk-05d77e-2025-12-08T08:17:31Z [View official notice](https://www.find-tender.service.gov.uk/Notice/ocds-h6vhtk-05d77e-2025-12-08T08:17:31Z) Never miss a tender like this again Get AI summaries, deadline alerts and a bid pipeline for tenders matched to your business.
