Lisvane and Llanishen Reservoirs forms a vital part of the green and blue infrastructure of Cardiff. The mix of grassland, woodland, scrub and waterside habitats offers opportunities for all kinds of wildlife and nature. There are two Sites of Special Scientific Interest (SSSI) and much of the grassland and woodland outside of the SSSIs is designated as a Site of Importance for Nature Conservation (SINC). 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. 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. There is a fully accessible Visitor Centre with cafe, toilets, free wi-fi, room hire, equipment hire, changing rooms and other facilities include the boathouse, bird hide, education centre, nature trails and paths, bike parking/shelters and car parking.
