The decline of Ireland’s marine gem calls for urgent action
Ireland’s first marine reserve, Lough Hyne, is suffering from pollution, mismanagement and overuse, threatening its once-thriving marine life and storied history as a research hub.
Olive Heffernan reports for Hakai.
In short:
- Lough Hyne’s purple sea urchins, a keystone species, have nearly vanished, allowing nutrient-driven algae blooms to choke the ecosystem.
- Agricultural runoff, tourism and poaching exacerbate the lough’s decline, while regulatory oversight and monitoring remain inadequate.
- Experts warn that without a comprehensive conservation plan, the lough’s biodiversity will continue to deteriorate, reflecting broader global challenges in marine protection.
Key quote:
“It’s been a gradual decline in all sorts of things over decades. The north shore is basically dead now.”
— Colin Little, marine biologist
Why this matters:
Experts argue that saving the lough will require more than well-meaning promises; it demands a serious conservation plan that could set a precedent for protecting marine reserves everywhere. As pollution and climate change threaten ocean biodiversity, proactive conservation efforts could help preserve ecosystems critical to health, food security, and climate resilience.
