Older Than the Map: Six Plants That Test a Wood's Continuity

Trees can be felled and replanted within a generation, but the ground flora of a Scottish wood holds a longer memory. Here is a field guide to six plants that hint at continuity — and a careful account of what their presence, and their absence, can and cannot prove.

After the Gale: What a Storm-Battered Wood Needs, and What It Does Not

A winter storm can undo twenty years of management in an afternoon, and the instinct to tidy up afterwards is almost always wrong. This is a measured guide to assessing windblown native woodland, working within the rules, and leaving the right kind of mess behind.

After the Photograph: A Three-Winter Audit for Scotland's New Native Woods

Planting day is the photograph; the first three winters are the test. As the 2026 planting season gets underway, this practical audit looks beyond sapling counts to site preparation, provenance, herbivore pressure, weed control and aftercare, arguing that long-term monitoring matters more than a single successful planting event.

The Browsing Line: Deer, Density and the Future of Scotland's Native Woods

Deer browsing is one of the quietest forces shaping Scotland's native woods, influencing seedling survival, shrub cover and canopy structure. This balanced assessment examines fenced and unfenced regeneration, the science of deer density, and the trade-offs between fencing, culling and natural processes.

What the Bark Is Telling Us: A Field Guide to Lichens in Scottish Woods

Lichens are quiet recorders of the air around them, turning bark into a visible register of pollution and woodland condition. This beginner’s guide explains how to read the common growth forms, recognise the species that favour clean air, and contribute useful records from a Scottish wood.

Moving Trees North: The Uneasy Case for Assisted Migration in Scotland

Assisted migration promises to help Scotland’s native trees keep pace with a warming climate, but it also risks unsettling the genetic and ecological fabric of ancient woods. This measured appraisal weighs provenance trials, woodland fragmentation and the precautionary case for restraint.

What Lies Beneath the Pines: A Measured Look at Woodland Fungal Networks

The idea of a forest internet is memorable, but Scotland's mycorrhizal fungi deserve a more careful story. This piece separates genuine wonder from overclaim, and explains why soil, roots and deadwood matter for conservation and outdoor learning.

Field Notes from a Living Wood: Seven Clues to Woodland Health

Counting trees is a start, but it is a poor measure of a woodland's health. These seven field clues help walkers and volunteers read a Scottish wood more like an ecologist, while recognising the limits of what any single sign can tell us.

Five Quiet Giants of the Winter Wood: Native Trees to Recognise on a Scottish Walk

Winter strips back the canopy and reveals the structure of Scotland's native woodlands. This practical guide profiles Scots pine, rowan, birch, hazel and aspen, with identification tips for bark, buds and silhouette.

The Case for a Wilder Mess: Rethinking Order in Scotland's Native Woodlands

Scotland's native woodlands are often judged by how tidy they look, but ecological health depends on deadwood, scrub and uneven edges. This opinion-led analysis argues that a less manicured approach can support insects, birds and fungi without sacrificing access or safety.
