About

16 Years Documenting Ireland's Natural Heritage

Séamus developed his passion for Ireland's natural world during childhood exploring the sheltered bays and coastal woodlands of West Cork. After completing his environmental science degree at UCC in 2008, he spent five years as a research assistant with the Irish Wildlife Trust, conducting population surveys of harbour seals across the southern coast. His breakthrough came in 2013 when his documentary work on seal behaviour in Glengarriff earned recognition from the Irish Wildlife Media Awards.

What drives Séamus is bridging the gap between scientific conservation work and public understanding. He's become a trusted voice in nature journalism, contributing to RTE's natural history programmes and leading guided walks that educate visitors about local ecosystems. When people truly understand their local wildlife, they become its best advocates. His approach combines field observation, ecological data, and storytelling to reveal the remarkable natural heritage found in places like Glengarriff's bamboo park and the harbour seal colonies that call these sheltered waters home.
