January 30th 2017:  informal survey of sword fern die-off locations

 

High Confidence Sites 

1. Seward Park's ground zero
2. Upper Luther Burbank Park (no formal assay yet)

Medium Confidence Sites  (false positives possible)

1. Seward Park, northwest corner
2. Cheasty Moutain View
3. Lake Sammamish
4. North Mercerdale
5. Dead Horse Canyon (15 recently dead ferns within 600  sq. ft. - forest steward Peter Mason)
6. Coal Creek

The intrepid and observant Al Smith contributed ALL of the die-off reports in the map except for the original ground zero site.   Our research would be impoverished without his contributions.
