Angling & water
Salmonid waters, water-body status, the catchments feeding them, and which agricultural pressure each sub-basin needs work on. Ireland runs a WHOLE-TERRITORY Nitrates Action Programme (S.I. 113/2022), so there are no NVZ lines to look for: the sub-basin flags are the risk differentiation other countries get from zone boundaries.
