Native Plants
If you've walked a shaded trail in the Pacific Northwest and seen glossy, feather-shaped fronds low to the ground, you've likely passed this exact fern, and sightings like this one help map where native understory plants still thrive.
Someone spotted a western sword fern growing in the Greater Vancouver area and logged it on iNaturalist, where other experts reviewed the photo and confirmed the identification. It's now a verified, research-grade record that adds to our picture of where this common native plant grows.
Key Findings
Observation was verified as research-grade, meaning the species ID was confirmed by community consensus
