High in the hills of the Snowdonia National Park in Wales, can be found a rare and fascinating habitat. We all know of the importance of the Tropical Rainforests, however these Celtic Rainforests are in a way even rarer, with Britain being home to most of the best preserved examples in the World. The Valley is changing and time could possibly be running out for these remarkable and sensitive habitats, which have been suffering from pollution and climate change since the dawn of the Industrial Age. Brett Westwood relives programmes from The Living World archives, this episode from 2011. Wales is home to a remarkable and rare forest. Paul Evans joins Ray Woods from Plantlife Cymru in Snowdonia.In an area where 200 days of rain each year is normal, Paul and Ray don their waterproofs and venture up the valley of the Rhaeadr Ddu, the Black Waterfall. The landscape in this valley is dominated by water, not only from the exceptional rainfall this area is known for, but from the river thundering along many rapids and waterfalls providing a constant mist of high humidity within the Atlantic wood enveloping the valley. Linked to a mild climate in this part of Wales, everything in the woodland is a carpeted in a magical sea of emerald green moss, fungi and lichen. This valley is home to some rare and exotic plants, the filmy ferns are however special in this landscape. Ray and Paul eventually make it to the side of the huge Rhaeadr Ddu waterfall itself, where, as the roar of the water almost drowns their voices, there on a single rocky outcrop, bathed in constant spray they discover the rare, minute and exotically beautiful Tunbridge Filmy-fern. Nearby a Wilson's Filmy-fern is found on a single boulder of an ancient moss encrusted dry stone wall. How did this Filmy-fern get here is a point of discussion.

Around 100,000 dark bellied brent geese head to Britain every winter to escape the extreme cold weather of their arctic breeding grounds in Russia. Britain is therefore an important wintering ground for these geese with many thousands heading to the Essex Marshes. But what brings them here and what are the management needs of this populated area of the South East coastal? To find out for himself, as Brett Westwood introduces in this Living World episode first broadcast in 2005, Peter France heads over to the Essex coastline in the company of ecologist Graeme Underwood from Essex University and Chris Tyas from the RSPB. Overlooking the wide marginal landscape wedged between the sea and the land they discuss mudflats and difference between marine and freshwater marshes. An ever changing landscape that requires specific management with all the challenges of creating the best habitat for all plants and animals here, including the thousands of dark bellied brent geese, in front of them.
