Urban Ecology
Tracking where native ferns like maidenhair spleenwort naturally grow helps gardeners and conservationists understand which plants belong in local ecosystems — and whether those populations are expanding, shrinking, or holding steady over time.
Someone spotted and carefully documented a small, elegant fern called maidenhair spleenwort growing in West Vancouver. This fern is known for its tiny, rounded leaflets arranged along dark, wiry stems — it often tucks itself into rocky crevices or shaded cliff faces. Recording exactly where it grows helps build a bigger picture of how native plants are faring in urban and coastal areas.
Key Findings
A research-grade observation of maidenhair spleenwort (Asplenium trichomanes) was confirmed in Marine Dr, West Vancouver, BC, Canada.
The observation is classified as research-grade, meaning it meets iNaturalist's standards for community-verified species identification.
The location — coastal British Columbia — falls within the known but locally patchy range of this fern, adding a data point to its distribution map.
