Flora

Western blanket bog and heathland are the most common vegetation of Connemara National Park. The boglands are situated in wet low-lying environments whereas the blanket bog exists within the drier mountain atmosphere. Purple moorgrass is the most bountiful plant, creating colorful landscapes throughout the countryside. Carnivorous plants play an important role in the park's ecosystem, the most common being sundew and butterworts trap. Bogs hold very little nutrients so many plants obtain their energy from the digestion of insects. Other common plants include lousewort, bog cotton, milkwort, bog asphodel, orchids and bog myrtle, with a variety of lichens and mosses.

Fauna

Connemara National Park is noted for its diversity of bird life. Common song birds include meadow pipits, skylarks, European stonechats, common chaffinches, European robins and Eurasian wrens. Native birds of prey include the common kestrel and Eurasian sparrowhawk with the merlin and peregrine falcon being seen less frequently. Woodcock, common snipe, common starling, song thrush, mistle thrush, redwing, fieldfare and mountain goat migrate to Connemara during the winter.

Mammals are often difficult to find but are present nonetheless. Field mice are common in the woodlands. Badgers, foxes, pine martens, and bats may be observed at night. Other mammals seen in the national park include red deer, otters, hares, stoats, and pygmy shrews.^[4] Red deer, once common in the area but extirpated approximately 150 years ago, were recently reintroduced to the park. Now the largest mammal in the park is the Connemara pony.^[5]
