western redcedar
Thuja plicataAlso known as Western Red Cedar, Pacific Red Cedar, Giant Arborvitae, Shinglewood
Western redcedars dominate the damp, moss-draped forests of the Pacific Northwest, easily recognized by their massive, fluted trunks and drooping branches that sweep upward at the tips. Their scale-like, aromatic leaves form flat, lacy sprays that release a sweet, pineapple-like scent when crushed. These ancient giants play a vital ecological and cultural role, providing critical winter shelter for wildlife and serving as a cornerstone resource for Indigenous coastal nations.

- Why interaction risk is low
- Safe to observe at a normal distance.
- What to notice
- Look for exceptionally wide, deeply fluted trunks with grey, stringy bark and dead, spike-like tops.
- Support conservation
- Stay on designated trails to prevent soil compaction around the shallow, sensitive root systems of these ancient giants.
Responsible observation
- Identify by scent: Crush a small sprig of the scale-like foliage to release a sweet, pineapple-like aroma.
- Look for cones: Search the branch tips for tiny, woody cones that resemble miniature rosebuds when open.
- Respect old growth: Avoid stepping on the sensitive, shallow root systems of ancient specimens.
