Ireland's Plant Ark: Seeds Saved for Future Disasters

Conservation ecologist Darren Reidy is leading Ireland's ambitious native seed banking project, established in 2019 and active since 2022. This initiative, likened to 'Noah's Ark,' aims to preserve the genetic diversity of Irish flora for future ecological recovery. Reidy's office at the National Botanic Gardens in Dublin houses the seed bank, remarkably storing seeds of all 900 native species, with a matchbox serving as a testament to its compact nature.

The process involves meticulously collecting, cleaning, drying, and freezing seeds at minus 20C, ensuring viability for up to 200 years. For species like orchids and oaks, cryopreservation is employed. Reidy has focused on endangered plants, successfully banking 137 species to date, including 34 from Ireland's red-listed flora, highlighting the urgency of 21st-century biodiversity loss.

While seed banking is a crucial 'cog in the bigger wheel of conservation,' Reidy emphasizes that it must be coupled with landscape and habitat management. Past successes, like the reintroduction of sea cottonweed, demonstrate the potential for replanting species in restored habitats, offering a tangible path towards the renewal of Ireland's threatened plant life.
