In this episode Cathy and Jo travel east to Poland. Join them along the way as they cross borders and head into the primaeval forests of Bialowieza and the vast marshlands of Biebrza - both complex ecosystems, alive with the sounds of mammals, birds and amphibians. The variety and abundance of species they encounter are astounding but also give them pause to reflect on what Britain has lost and why.

Jo and Cathy spend this episode with National Trust project officer and ecologist Steve Hindle on the slopes of Calderdale, in what looks like an ordinary field… but isn’t. They discuss the fascinating lives of fungi and their vital but often overlooked role in the ecosystem, not only as decomposers or parasites, but also as symbiotic partners engaged in a range of very sophisticated relationships with plants. Steve’s partner Sarah Flood scours the field for waxcaps, pinkgills, clubs, corals and earthtongues. Each has their own ecological niche, and all are indicators of ‘ancient grassland’, a rare habitat which Calderdale, with its challenging farming conditions, has managed to hold on to. Landowner Liz tells of the sometimes confusing journey her and her partner took to work out the best management options for the field, the steps they are taking to protect it, and of course, her new found passion for fungi!

If you go up to Calderdale’s rough pasture and moorland during the spring and early summer you might encounter a variety of breeding birds – small ones like meadow pipits and skylarks and larger ones like oyster-catchers, golden plover, snipe and lapwings. There is perhaps none more distinctive though, both in its look and sound than the curlew – a large, elegant, brown wader with a very long curved beak and a strange, some say ghostly, bubbling song. Whilst numbers across Britain are going down and down, here in the South Pennines, we still experience their arrival every spring and seem to be holding on to our breeding curlew population. In this episode Cathy recounts her lifelong love for this iconic bird and discusses her British Trust for Ornithology (BTO) survey work, sharing insights on local population levels and how we might conserve them. We also visit a nearby beauty spot (the Bridestones) and speak to local expert Andrew Cockcroft about a community-led initiative to buy the 114-acre site and restore its peat bog and acid grassland ecosystems for the benefit of wading birds as well as other wildlife, and people.
