Sightings of invasive/non-native species
Sightings of injurious weeds (including Common ragwort)
Primary responsibility for weed control rests with the occupier of the land on which the weeds are growing. It is important to be alert to potential weed problems and take action quickly. More information can be found on Welsh Government’s Injurious weeds page.
If you spot a stranded marine animal, please visit the UK Cetacean Strandings Programme Website for details on how to file a report.
