Discover the Flora & Fauna of the Burren
The Burren is a botanical wonder, where Arctic, Alpine, and Mediterranean plants thrive together in a unique limestone landscape. This rare combination of habitats creates a biodiversity hotspot with a rare mix of flora & fauna unlike anywhere else in the world. Our Burren Botany Bubble showcases the region’s extraordinary plant life, allowing visitors to see native species up close and learn about their fascinating adaptations.

Flora & Fauna Galleries
The Burren is renowned for its exceptional flora & Fauna, where arctic, alpine, and Mediterranean plants grow side by side in a rare ecological harmony. This unique plant diversity has been shaped over thousands of years by the region’s limestone geology, the scouring and soil deposits of the Ice Ages, and traditional farming practices such as reverse transhumance—where cattle graze the uplands in winter. These elements together have created ideal conditions for a rich variety of wildflowers to flourish, making the Burren one of Europe’s most important areas for botanical study.
Take a glimpse at the botany of the Burren in the galleries below.
Orchids of the Burren
The Burren is one of Ireland’s richest regions for wild orchids, with over 20 species thriving in its limestone grasslands. This diversity is supported by the unique combination of shallow soils, open habitats, and low-intensity grazing. Notable species include the Bee Orchid (Ophrys apifera) and Fly Orchid (Ophrys insectifera), both known for their insect-like blooms, the vibrant Pyramidal Orchid (Anacamptis pyramidalis), the sweet-scented Fragrant Orchid (Gymnadenia conopsea), and the rare Irish Orchid (Neotinea maculata), which flourishes in undisturbed areas.
Trees & Shrubs
The Burren supports a surprising variety of native trees, often growing in sheltered pockets of deeper soil and the crevices of limestone pavement known as grikes. Despite the exposed and rocky landscape, woodlands of hazel, ash, and hawthorn thrive alongside rarer species. Notable trees include Hazel (Corylus avellana), which dominates the Burren scrub; Ash(Fraxinus excelsior), now under threat from ash dieback; Scots Pine (Pinus sylvestris), a native conifer making a return; and Spindle (Euonymus europaeus), a delicate tree with striking pink fruit and vibrant autumn foliage.
Ferns of the Burren
The Burren is home to an exceptional range of ferns, thriving in the cool, moist microclimates of shaded grikes, cliff faces, and hazel woodlands. These ancient plants benefit from the region’s limestone geology and sheltered habitats, where humidity and protection from grazing allow them to flourish. Notable species include the Maidenhair Fern(Adiantum capillus-veneris), rare in Ireland and found in damp, sheltered spots; the Hart’s-tongue Fern (Asplenium scolopendrium), with its glossy, strap-like leaves; the Wall-rue (Asplenium ruta-muraria), growing in limestone crevices; and the Rustyback Fern (Asplenium ceterach), which curls its leaves tightly in dry weather to conserve moisture.
Limestone Coastal Plants
The Burren’s coastline hosts a unique range of salt-tolerant coastal plants adapted to harsh winds, salty spray, and rocky shores. These hardy species thrive where limestone meets the Atlantic, often forming colourful displays in crevices and along grassy banks. Notable coastal plants include Sea Thrift (Armeria maritima), with its pink pom-pom flowers; Rock Samphire (Crithmum maritimum), a fleshy herb once prized for pickling; Sea Campion (Silene uniflora), with delicate white blooms; and Scurvygrass (Cochlearia officinalis), rich in vitamin C and historically used to prevent scurvy.
Limestone Flora
The limestone pavement of the Burren supports a remarkable range of specialised flora, adapted to grow in the shallow soils and sheltered grikes of this unique karst landscape. These plants take advantage of the warmth-retaining stone and varied microclimates to thrive in otherwise harsh conditions. Notable limestone flora include Spring Gentian (Gentiana verna), a vivid blue flower symbolic of the Burren; Mountain Avens (Dryas octopetala), a relic of the Arctic tundra; Bloody Cranesbill (Geranium sanguineum), with its deep pink blooms; and Common Butterwort (Pinguicula vulgaris), a carnivorous plant found in damp limestone hollows.
Turloughs / Wetlands
The Burren’s turloughs and wetlands are seasonal and permanent water bodies that support a rich variety of specialised aquatic and semi-aquatic plants. These habitats, unique to limestone regions, flood in winter and dry in summer, creating dynamic conditions that encourage biodiversity. Notable species include Water Lobelia (Lobelia dortmanna), found in clear, nutrient-poor water; Bogbean (Menyanthes trifoliata), with its distinctive star-like flowers; Marsh Helleborine(Epipactis palustris), a striking wetland orchid; and Quillwort (Isoetes lacustris), a rare aquatic plant rooted in turlough beds.
Burren Butterflies
The Burren is a haven for butterflies, with over 28 species recorded, thriving in its rich mosaic of wildflowers, warm limestone, and sheltered habitats. The region’s low-intensity farming and diverse flora provide ideal feeding and breeding conditions. Notable species include the Pearl-bordered Fritillary (Boloria euphrosyne), Common Blue (Polyommatus icarus), Dark Green Fritillary (Speyeria aglaja), Dingy Skipper (Erynnis tages), and the rare Marsh Fritillary(Euphydryas aurinia), which is a priority species for conservation in Ireland.
Burren Birds
The Burren supports a variety of birdlife, benefiting from its open grasslands, rocky outcrops, wetlands, and woodlands. The mix of habitats provides feeding, nesting, and roosting grounds for both resident and migratory species. Key birds include the Wheatear (Oenanthe oenanthe), often seen on rocky terrain; the Cuckoo (Cuculus canorus), whose distinctive call marks spring; Skylark (Alauda arvensis), celebrated for its song-flight; Stonechat (Saxicola rubicola); and wetland visitors like Snipe (Gallinago gallinago) and Little Egret (Egretta garzetta).
Burren Mammals
The Burren’s varied landscape supports a range of native mammals, many of which are elusive but play vital roles in the local ecosystem. Hedgerows, scrub, caves, and woodland offer important shelter and foraging grounds. Notable species include the Irish Hare (Lepus timidus hibernicus), a subspecies found only in Ireland; Pine Marten (Martes martes), which has made a strong recovery in the Burren; Otter (Lutra lutra), seen around rivers and turloughs; Badger (Meles meles); and several bat species, including the Lesser Horseshoe Bat (Rhinolophus hipposideros), which roosts in Burren caves and buildings.
