Overview

Pembrokeshire Coast National Park Authority invites proposals from consultants to identify and prioritise nature-based intervention opportunities that could contribute to improving water quality in the lower Western Cleddau (and possibly other relevant catchments if feasible within the budget). A transparent, weighted multi-criteria approach will assess water quality benefit, source / pathway / receptor linkages, hydrological connectivity, intervention potential and implementation feasibility. GIS analysis will identify and map pollution sources, pathways, receptors and priority reaches using available datasets. Stakeholder and landowner engagement will support fieldwork access, inform feasibility and foster future implementation support. Targeted walkovers will ground-truth and refine the assessment, identifying opportunities and constraints not evident from desk-based information. Outputs will include an updateable GIS opportunity and prioritisation database, mapbook, narrative report and selected case studies / scenarios. The assessment should distinguish between strategic priorities and actionable opportunities and briefly consider future nutrient mitigation / credit potential of interventions (and how this might influence take-up). Budget: £38,000 ex VAT, funded by Esteé Lauder Companies UK & Ireland via the UK National Parks Foundation. Mae Awdurdod Parc Cenedlaethol Arfordir Penfro yn gwahodd cynigion gan ymgynghorwyr i nodi a blaenoriaethu cyfleoedd ymyrryd sy’n seiliedig ar natur a allai gyfrannu at wella ansawdd dŵr yn rhan isaf Cleddau Wen (ac efallai dalgylchoedd perthnasol eraill os yw hynny’n ymarferol o fewn y gyllideb). Bydd dull tryloyw, wedi’i bwysoli, gyda nifer o feini prawf yn asesu mantais o ran ansawdd dŵr, cysylltiadau tarddle / llwybr / derbynnydd, cysylltedd hydrolegol, posibilrwydd ymyrryd a dichonoldeb gweithredu. Bydd dadansoddiad GIS yn nodi ac yn mapio tarddleoedd, llwybrau, derbynyddion a rhannau blaenoriaeth llygredd gan ddefnyddio’r setiau data sydd ar gael. Bydd ymgysylltu â rhanddeiliaid a thirfeddianwyr yn cefnogi mynediad at waith maes, yn llywio dichonoldeb ac yn meithrin cymorth gweithredu yn y dyfodol. Bydd teithiau cerdded wedi’u targedu yn cadarnhau ac yn mireinio’r asesiad, gan nodi cyfleoedd a chyfyngiadau nad ydynt yn amlwg o wybodaeth desg. Bydd yr allbynnau’n cynnwys cronfa ddata blaenoriaethu a chyfleoedd GIS y gellir eu diweddaru, llyfr mapiau, adroddiad naratif ac astudiaethau achos / senarios dethol. Dylai’r asesiad wahaniaethu rhwng blaenoriaethau strategol a chyfleoedd y gellir eu rhoi ar waith ac ystyried yn gryno botensial ymyriadau i liniaru maethynnau / credydau yn y dyfodol (a sut y gallai hyn ddylanwadu ar y nifer sy’n manteisio arnynt). Cyllideb: £38,000 heb gynnwys TAW, sy’n cael ei ariannu gan Esteé Lauder Companies UK & Ireland drwy Sefydliad Parciau Cenedlaethol y DU.
