12 km. 900 metres of ascent. Much on rough terrain away from paths.

Be a part of something big and take your Munro-bagging to new heights by climbing a Munro and doing some science! 

The alpine zone on Scottish mountain summits includes some of our most important natural and undisturbed habitats, but these are being impacted by climate change and other factors such as air pollution. The myriad of organisms, both large and small, which live in soil are crucial for the functioning of habitats and influence important processes such as carbon storage and provision of clean water. In the alpine zone soil biodiversity has hardly been explored, we know very little about the species living in these soils and potentially we could lose them before we even know that they are there.

Mountain Heights, Hidden Depths is a project, run by the James Hutton Institute, which aims to radically change this by using DNA sequencing to detect and identify organisms in soil samples collected from the summits of the 282 Munros across Scotland. This will enable us to develop a picture of how soil biodiversity varies across Scotland’s alpine zone, to identify areas of high soil biodiversity, and to create a baseline against which to measure future change.

OutdoorLads will help by gathering soil samples from three points on the summit of Ben Challum, near Tyndrum. We'll take an interesting route up Gleann a' Chachain, through regenerating mountain woodlands, before reaching the northerly ridge which leads to the summit of Ben Challum. We'll bag the Munro and then navigate to three pre-determined points near the summit, where we'll take some measurements and soil samples for DNA sequencing. When we trialled this method in the Cairngorms last year, we discovered two species never recorded in the UK before, and one species completely new to science! Who knows what we will discover on Ben Challum.

We'll then drop back down into the glen on the south-western ridge of the mountain, safe in the knowledge that we've done our bit for science and nature conservation. The leader will get our soil samples back to the lab for sequencing, and we will wait to see what the project finds...
