Brett Westwood presents. We take a look at British farmland and ask how fit it is for wildlife to flourish. We go in search of the small flower the Blue Pimpernel and Britain's "Big Six" of farmland birds to discover what changes to farming arable land have been needed to allow them to re-emerge. We also feature a report from South America where Mark Brazil has had a close encounter with the Maned Wolf - one of the rarest mammals in the world and perhaps one of the least understood. With news from Kelvin Boot.

Lionel Kelleway travels to Herefordshire to marvel at the Old Masters of the British countryside; ancient trees, including the oldest oak in Britain.

This week Brett Westwood presents a programme featuring a report from Japan about whooper swans. Brett visits a garden that has become a site of national importance because of its diversity of fungi, before discussing the conservation of fungi with an expert from Kew Gardens. Also in the programme a 'Memories' piece about freshwater fish and our regular wildlife news with Kelvin Boot.

Brett Westwood presents. Saving Species looks into the issues of invasive species. What should countries do with wildlife aliens? When does a non-native species, like an eagle owl, become "invasive"? We discuss whether the eradication of invasive species in any one setting is wildlife conservation. With news from Kelvin Boot.

Lionel Kelleway visits hedgerow ecologist Rob Walton on a farm in Devon, where they explore the value of hedges for wildlife and search for a dormouse along the way.

Brett Westwood presents. We return to St Bee's Island off the Queensland coast in Australia for our second exclusive report about Koalas. We also feature a special report from Madagascar and the work being done out there to save the Madgascan Pochard from the brink of extinction. Chris Sperring sends a report to us from Orkney where the Grey Seals are pupping. With news from Kelvin Boot.

The British Isles are home to 6500 species of wasps and bees. Lionel Kelleway travels to Devon in the hope of seeing a potter wasp bringing paralysed caterpillars to the pot.

Brett Westwood presents a programme full of geese. Joanna Pinnock witnesses the arrival in Norfolk of pink-footed geese, while Michael Scott visits the Scottish island of Islay. Geese migration is a spectacle, but is it also a problem? We have perspectives from farmers and conservation organisations. Finally, Kelvin Boot sums up developments from the Nagoya biodiversity conference.

Brett Westwood presents. In the light of the British Government's spending review, is it business as usual for running nature reserves? Also in the programme, we have a live report from Nagoya in Japan where governments and conservation organisations from around the world have been meeting to discuss new biodiversity targets. Chris Sperring has his eye on Fallow Deer and brings you the spectacle of their rut on Exmoor together with their impacts of woodland. And Kelvin Boot has been with iSpot users in the New Forest looking for fungi.

Brett Westwood presents. Saving Species is in London looking for south-bound migrating birds. Ornithologist Ian Wallace has watched the skies wherever he’s lived since he was a young man, including London’s Primrose Hill. So how would his earlier findings compare with todays visible migration? And we'll have a special piece from a sacred forest in Ethiopia, a unique wooded island refuge in a desert of over tilled land - a forest protected by a church and its followers. We hear from Claire Ozanne from Roehampton University as she and colleagues conduct the first ever wildlife survey of this refuge.

Brett Westwood presents. In earlier episodes of Saving Species we followed the life and times of British seabirds on the Isle of May and the Cliffs near Tain, both in Scotland. Over recent weeks lots of data has been crunched and we have ornithologist Bob Swann telling us how Fulmars, Kittiwakes, Puffins and Shags and other seabirds have done in various places around the UK. Biologists from Oxford University have been studying the decline in British birds and have come up with work that indicates that bird decline in the UK is an indicator of wider mass extinctions over the world. Also, bees. We report new research looking at what the Honey Bee waggle dance tells us about nectar sources in gardens and the countryside. And to a great source of autumn nectar, Kelvin Boot hunts down the Ivy Bee.

Brett Westwood presents. Chris Sperring reports from a woodland in Wales amongst erupting fruiting bodies and discovers the importance of conserving fungi for the health of woodlands. Ted Oakes is back in the Minnesota woodlands trying to locate black bears and see how they are responding to conservation. We're also back in Africa with a report from Tessa McGregor about the successful conservation of the Grevy's Zebra in the Samburu National Park in Kenya. With news from Kelvin Boot.

Presented by Kelvin Boot. Saving Species visits the Mississippi Delta and asks naturalists and biologists "just how tough are the oceans' defences to huge pollution events like the recent oil spill"? Howard Stableford will be in the area gathering information about the resilience of a huge river Delta and its relationship with the sea. How much flex is in the system? We'll find out.

Brett Westwood presents. Saba Douglas-Hamilton reports from Samburu national park in Kenya. In her first report we hear about the affects of severe flooding after a period of sustained drought on the savannah and get an insight into the elephants within the national park. And we hear from Mark Brazil in the Aleution Islands (a string of islands streaming off the western tip of Alaska) and his close encounters with Stellers Sea Lions. And in the UK, culm grassland making a return - the preferred habitat of the Marsh Fritillary. With news from Kelvin Boot.

Brett Westwood presents. We focus on the seabird species the Little Auk which inhabit the northern archipelago of Svalbard at the height of their breeding season. Joanna Pinnock visits a compost heap in Cambridgeshire. And we follow on this theme with a special studio guest who needs a warm living compost heap to successfully raise her young - the Grass Snake. Also in the programme we feature the Large Blue Butterfly.
