Glasdrum Wood (Scottish Gaelic: Coille a’ Ghlasdroma)[3] is national nature reserve (NNR) at the head of Loch Creran in Argyll and Bute on the west coast of Scotland.

Managed by NatureScot, the wood is renowned for its diverse flora and fauna, including sessile oak and ash trees, mosses, liverworts and rare invertebrates, like the chequered skipper butterfly.

The remains of charcoal platforms and a limekiln, which date from the 18th and 19th centuries provide evidence of industrial activity that required large quantities of wood.

The commission enclosed part of Glasdrum Wood with a deer fence, and began to clear the deciduous woodland to plant conifer species.

[8] This includes the rare chequered skipper butterfly, a priority United Kingdom Biodiversity Action Plan species that was declared extinct in England in 1976.
