Slugs are sometimes regarded as a garden pest, but they are more important than people might think. Rachel meets with retired teacher and slug expert Chris Du Feu after one of his workshops in Rosyth run by the Fife Nature Records Centre to ask whether he had noticed more slugs than usual this year.

It’s rare these days to see a mature elm tree be it in the countryside or in our towns and cities. That’s because of Dutch Elm Disease which, over the past sixty years, has killed millions of trees throughout the UK. In this week’s Scotland Outdoors episode, Helen Needham visits Max Coleman of the Royal Botanic Gardens who has been involved in a Scottish project to create resilient elms for the future.

Montrose Basin have recently been welcoming annual visitors pink-footed geese, who migrate from Iceland every year. Mark hears more about these spectacular birds from Visitor Centre Manager Joanna Peaker and freshwater ecologist Rachel Mackay-Austin.

The harbour in Stranraer is at the heart of much of the regeneration of the town. Rachel met with historian Elaine Barton at the West Pier overlooking Loch Ryan to discuss the major role the loch played in the local economy.

The October holidays in Scotland are traditionally called tattie holidays, as this is the time when children would be taken out of school to help with the potato harvest. Potato expert and “Tattie Talks” organiser John Marshall joins Mark and Rachel live to tell us more about how tattie picking has changed over the years.

When we think of surfing, we don’t usually associate it with the cold waters of the north of Scotland. University of Edinburgh lecturer Dr Matthew McDowell has recently published a book looking at the history of surfing in the north of Scotland. Mark meets him at Dunbar beach, one of Scotland’s best surfing beaches, to discuss his findings.

Returning to Stranraer, Rachel visits Aldouran Wetland Garden, a garden managed by volunteers, which lies just a few miles out of town. The site sits on the edge of woodland and features a pond, raised flower beds and a bird hide, as well as a rather interesting hungry caterpillar. Gordon Weymss and Jane Sloan gave Rachel a guided tour.

Now that we are further into the autumn months, we start to notice the leaves changing on the trees. Mark meets artist Jonathan Mitchell to discuss the many colours involved in autumn leaves, and how they inspire his paintings.

Highlands and Islands Airports Limited staff have teamed up with conservation programme Species on the Edge to create safe nesting habitat for the rare Little Tern at Islay Airport. Rachel meets Project Officer Lucy Atkinson to learn more about the project and the birds.
