Description

Skelmorlie Glen Skelmorlie Glen, lying around 1km south east of the town of Skelmorlie, is one of the best examples of semi-natural woodland in North Ayrshire. It is a botanically-rich mixed deciduous valley woodland, the stream sides and lower slopes of which are dominated by alder, but in the higher areas ash/elm and eventually oak/birch assume dominance. The understorey is predominantly of hazel but bird cherry, rowan and regenerating canopy species are locally abundant. The ground flora is diverse and indicative of undisturbed woodland cover. Higher plants present include woodruff (Galium odoratum), sanicle (Sanicula europaea), dog's mercury (Mercurialis perennis) and wood melick (Melica uniflora), as well as less common species such as alternate leaved golden-saxifrage (Chrysosplenium alternifolium), smooth-stalked sedge (Carex laevigata), giant bellflower (Campanula latifolia) and wood stitchwort (Stellaria nemorum).

Insects to look out for

These moths, butterflies and beetles are known to feed on plants recorded at this site, and carry a notable UK conservation status — but a host-plant being present doesn't mean the insect has actually been recorded here. Treat this as "worth watching for," not a confirmed sighting.
