Galwad Cynnar is a Welsh-language nature programme from BBC Radio Cymru, and it runs on conversation. A host brings in a panel and guests, reads out a phone number and a text line, and points people to Twitter and a Facebook group carrying the programme's name. Named panellists include Elinor Gwynn and Dr. Prysor Williams. Rhian Brewster joins one programme, Mike Parker comes on to discuss the book 'Map Addict', and Dave Hughes is thanked 'as always' at the end of one programme. The pull of the show is how easily it moves between the very small and the very large. Start with the pond. One contributor describes spending around an hour watching a male newt wave its tail to attract females. The detail keeps coming: newts lay their eggs a little later than frogs, and these ones had already eaten the frogspawn and tadpoles in the pond. Oswyn Williams is credited with sending in a photo of a newt. Then the scale jumps. A speaker from a park recalls Everest being called the world's highest rubbish dump. Climbers spend large sums on the trip, much of it flowing into Nepal's economy, and Sherpas struggled financially once Covid stopped the climbing. The speaker presents the next part as welcome good news: a campaign used the quiet to clear tonnes of waste from four of the highest Himalayan mountains. The story is then brought home to a new campaign asking people to plan, discover and love the park, and to think about where their litter ends up. Insects get the same close attention. Hawkmoths with long tongues, able to reach into a flower for its nectar, are named as the suggested pollinators for a plant a university is working with. Landscape runs through all of it. A stream running down from Pen y Gwryd towards the lakes comes up, and during the same conversation a photo of someone measuring rain on a mountain slope is found and promised to the Facebook group before the programme ends. Maps get a conversation of their own through Mike Parker and 'Map Addict'. Questions reach the panel with a name attached, and the talk stays conversational rather than lecturing. In Galwad Cynnar, a newt's courtship and a Himalayan clean-up belong to the same subject.
