Wester Sword Fern Dieback tracking project

This project from south of the border is tracking what appears to be dieback issues happening with sword fern.

"What could be more iconic of the PNW than a lush fern understory? Unfortunately, previously healthy stands of western sword fern (Polystichum munitum) have been declining throughout the Puget Sound Region (western U.S.) in the course of the past decade. The cause of the decline is not yet known and we need your help to identify potential sites where sword ferns may be affected."

While there isn't any indication this is an issue here in BC it is good to be on the lookout to identify any possible occurrences.
