===Vegetation (spring) of Moel Gornach===
''Palustriella falcata ''dominated short vegetation between 1–3 cm height. ''Palustriella commutata ''forms locally dominant patches around the upper rocky spring heads and ''Scorpidium cossonii ''locally dominates the margins of runnels (or hollows where there is movement of water) lower down the slope. ''Hymenostylium recurvirostrum ''forms occasional cushions associated with exposed tufa and ''Leicolea bantriensis ''occurs locally.

===Vegetation adjoining spring===
Upland acid grassland to 30 cm height (''Nardus stricta, Hylocomium splendens, Juncus squarrosos, ''occasional ''Vaccinium myrtillus''). There are ocassional small areas of rush pasture (''Juncus effusus'') as well as regular boggy areas with ''Polytrichum commune, Eriophorum angustifolium ''and ''Sphagnum species.''
