White Lake Fen

Macnamara Field Naturalists’ Club field trip to White Lake Fen (AM) and Stewartville Cedar Swamp (PM)

Wh l fen STewswamp24ju12 068

This was an excellent 5 hour trudge through, initially, the Fen. On a hot day, the cool fen water seeping into my old sneakers felt so good. Led by the ever knowledgeable Michael Runtz, the eager group of ten came upon bog and fen species at the Fen and, some interesting additional species at Stewartville Swamp. The Swamp’s orchids have greatly been reduced since my last visit 3 years ago, due to fallen cedars, and resultant opening of the canopy. 

 At the Fen, aside from a stunning display of Showy Lady’s Slipper, many other botanical specialties and insects were noted (see list). My favourites were the tiny Elfin Skimmer and the Bog Copper.
