It's time for the second Big River Watch of the year. It’s a chance to spend time observing the health of your local river between the 6th and 12th of September. The River Dee trust are taking part in the forthcoming survey and Keilidh Ewan, education and outreach officer for the trust gave Mark some more information.

A new trial is underway in Scotland which could cut the harmful emissions associated with manure on farms. Two farmers are trying out a system called Bokashi which the Soil Association hopes may lead to improvements in the soil while also being a little kinder to the environment. Rachel spoke to farmer Andrew Barbour at Glen Fincastle and Field Lab Co-ordinator Audrey Litterick who explained what this process actually involves.

Producer Phil met up with Ada Campbell, chair of Langass Community Woodland Trust to have a walk round one of the few forested areas on north Uist and hear the story of Hercules the bear.

Rachel recently bumped into an artist in Aberdeenshire who was on her way to a farm to collect a fleece for one of her new collections. Lucy MacDonald who is also a weaver likes to use local materials including wool and plants to make her work sustainable, traceable and authentic. Rachel joined her as she visited Diana Milligan and Cobweb – one of Diana’s rather interesting looking Ryeland Sheep.

The Isle of Rum has been designated as Scotland’s first International Dark Sky Sanctuary by DarkSky International. The designation recognises the efforts of the community to protect and promote the island’s starry skies and nocturnal environment. Isle of Rum Community Trust Director Fliss Fraser joins Mark and Rachel live to tell them more about Rum’s dark skies and the benefits the nocturnal environment brings to us and to the natural world.

The forest trails near Aberfoyle in the Trossachs have become increasingly popular in recent years for mountain bikers and gravel riders keen to get away from busy roads. The waymarked trails, in the shadow of Ben Lomond, have been named Gravelfoyle. Now, in a bid to attract more people to them a pilot called Parkride has been taking place; a bit like Parkrun but replacing running with biking. Alongside it parents can drop off their kids at ‘Bairns On Bikes’ where professional coaches teach youngsters basic and more advanced bike skills. Linda Sinclair went along to find out more.

Claudia Zeiske is a long distance walker and she has been walking from mountain to sea across Aberdeenshire. Mark met up with Claudia at the end of her journey at a place called Gadle Braes in Peterhead in what was a very blustery day to find out why exactly she had undertaken the walk

Lucy MacDonald's an artist who uses local fleeces and plants in her work. After she’s sorted through the fleece and given it a wash, she will put it through a carding machine before spinning it and weaving it. Rachel watched her in action at her studio in Aberdeen.
