The third seed we collected with South Assynt Collaboration Project, Trees for Life and The Assynt Foundation last Sunday was perhaps the least showy of the three — the tiny seed of the downy birch.
But birch has one of the longest stories in the Highland landscape.
After the last Ice Age, birch was among the first trees to recolonise Scotland. Today downy birch remains especially at home in the cool, wet and windy conditions of the north-west Highlands. As a pioneer tree it is also particularly good at colonising open and disturbed ground, helping woodland begin again.
And we can see birch in Assynt’s archaeological record.
At Loch na Claise, excavated by Historic Assynt and AOC in 2016, charcoal from birch was recovered from waterlogged floor deposits within the Iron Age island settlement. The site was occupied around the same broad period as Clachtoll Broch.
Go further back and birch appears again at the Bronze Age burnt mound at Stronchrubie, where it was found amongst the charcoal used by people living and working in the Assynt landscape thousands of years ago.
Birch is an extraordinarily useful tree. Its wood provides fuel and material for everyday objects, while its tough bark could be used for everything from containers and waterproofing to tanning and fire-lighting.
By the nineteenth century, the botanist John Louden remarked that “The Highlanders of Scotland make everything of it” — listing its use for household objects, agricultural implements, fuel, smoking fish and meat, thatching and bedding.
Even the sap could be tapped in spring. We heard from another seed collector that it is very tasty although hard to get your hands on!
The Gaelic name for birch, beithe, still survives in Highland place-names today.
So those tiny seeds we collected are part of a much bigger story: a tree that helped recolonise the Highland landscape after the Ice Age, was used by communities here for thousands of years, and is now being collected again to help regenerate the woodland of the future.
Many thanks to South Assynt Collaboration, Trees for Life and the Assynt Foundation for letting us join in.
