Mooney Goes Wild

Trees are vital for biodiversity, yet many Irish species have declined, including the Wych Elm, devastated by Dutch elm disease. But four mature elms in Rathmines appear to have survived. Arboricultural Consultant Joe McConville is investigating whether their genetics could help restore elms across Ireland...

Nature Nights Live returns to RTÉ Radio 1 from March 9th–13th, at 10–11pm, in partnership with the Tree Council of Ireland for National Tree Week. The programme will share event updates, celebrate native trees and nocturnal wildlife, feature expert guests, and invite listeners to ask questions and share sightings.

Grey Squirrels introduced in 1911 have impacted Ireland’s Red Squirrels, but the Reds are now rebounding due to increased Pine Marten numbers. The 2026 All-Ireland Squirrel and Pine Marten Survey has been launched, and Colin Lawton, Ecology Lecturer at the University of Galway, joins the programme to explain the project...

Derek Mulrooney, greenkeeper at Druids Glen, Wicklow, reports a gaggle of Greylag Geese returning after food was put out for ducks. He wonders if they’re from the original flock and how they knew food was back. To investigate, Terry Flanagan visits the course as the panellists consider possible explanations...

Tonight our experts respond to some of your e-mails and queries about ducks in California, Woodpeckers in Cavan, Buzzards in Waterford and the life span of garden birds, including Robins...

Grey Squirrels, introduced to Ireland in the early 1900s, are now widespread and have impacted the population of native Red Squirrels. They are long believed to descend from a dozen released in Longford in 1911. Our panel discusses whether later deliberate or accidental introductions also added to their numbers and genetics...

The Brent Goose, which breeds in High Arctic Canada, arrives in Dublin each autumn, gathering in estuaries, parks and green spaces to graze on grass. Ireland is crucial to this far-northern breeder. Ornithologist Kendrew Calhoun explains how public sightings help track populations, migration and breeding success for conservation...

Recent weeks have seen severe, localised flooding across Ireland, especially in counties Wicklow, Wexford and Dublin. Yet, as Éanna notes, Met Éireann says it was only the wettest January since 2018. Our panel discusses climate change, extreme weather and nature-based flood solutions...

Naturescapes is a European project using nature-based solutions at landscape scale to tackle socio-economic challenges, boost biodiversity and address climate change. Along the River Dodder, innovations like pocket forests are underway. Terry Flanagan met Mairéad O’Donnell of Trinity College Dublin to learn more...

Residents in parts of Co. Clare have been suffering a spate of power outages. The culprit: recently arrived Great Spotted Woodpeckers that have been excavating holes in wooden electricity poles, causing some of them to weaken and then snap in bad weather, bringing the power lines down with them. Derek and the panel discuss this unusual problem...

The Peregrine Falcon, the world’s fastest animal at 389 km/h, nearly went extinct due to the pesticide DDT but has recovered strongly in Ireland and worldwide. In recent years, a pair nested in the 300-ft belfry of St. Colman's Cathedral, successfully breeding in 2024. On tonight’s programme, Jim Wilson tells us more...

Ireland’s first Living Seawall at Kennedy Pier, Cobh Harbour, was developed by UCC, Research Ireland and the Port of Cork. Featuring habitat-rich panels with unique patterns of cups, ridges and depressions, it boosts marine life and water quality. Naturalist Jim Wilson speaks with marine ecologist Dr. Louise Firth from UCC BEES about the project...

While on holiday recently in Valencia, Spain, Derek noticed a species of bird that has become one of the staple performers in the Irish Dawn Chorus each year: the Collared Dove. First breeding in Ireland in 1959, they now consistently feature each winter in the Top 20 of BirdWatch Ireland’s Irish Garden Bird Survey...

Dr. Matthias Sinnesael, Assistant Professor in Geology at Trinity College Dublin, is one of the participants in a study trying better to understand the dinosaur extinction event and whether it was caused purely by the asteroid, or if extreme volcanic activity may also have played a role. He joins Richard, Eanna and Niall in studio to explain...

Dr. Peter Moonlight is the Curator of the Herbarium at Trinity College Dublin's School of Botany, which holds half a million dried plant specimens, including possibly the world’s oldest shamrock specimen! Who else would we send to chat to Peter about all of this but our resident botanist Éanna Ní Lamhna?

"Biophilia", or "love of life", is used to describe the innate tendency of humans to connect with nature. At the National Botanic Gardens in Glasnevin, guide Eoin O’Reilly organised a tour entitled Biophilia. We sent Terry Flanagan and Richard Collins along to learn more...

The EU has added Sika deer to the list of invasive alien species of concern in Ireland. But what does this mean in practice for deer management here? Damien Hannigan of the Irish Deer Commission joins us on tonight’s programme to tell us more...
