Dogs At Lisvane & Llanishen Reservoirs

Dogs are permitted on the café balcony, car park and Grab & Go seating area only and are not permitted anywhere else on the site, including the paths.

We know that this will be disappointing news to many nearby residents who would like to walk their dogs at Lisvane & Llanishen Reservoirs but we have to take seriously any threat to its designation as a site of special scientific interest (SSSI) for the rare waxcap fungi.

Natural Resources Wales has advised that the risk from dogs to the fungi is too great. Waxcaps are very sensitive to changes in habitat such as fluctuations in soil moisture, temperature and nitrate levels which can reduce the production of fruiting bodies. In particular, sudden changes to nitrate levels on the site – from dog urine specifically – can have a detrimental effect on the fungi.

Please note that the restrictions are not applicable to assistance dogs.
