Low tide at Longridge Point - compare with high tide in the video. The extensive mudflats, tidal pools and rocky shoreline are refreshed twice a day by the tide, creating habitat for feeding shorebirds.

“Northern Grass-of-Parnassus” (Parnassia palustris) now has the accepted common English name Marsh Grass-of-Parnassus, perhaps to better distinguish it from Parnassia parviflora (Small-flowered Grass-of-Parnassus and P. kotzebuei (no common English name), both of which are also northern in their distributions. (Don Sutherland pers. comm,)

Marsh Ragwort

 

We all were intrigued by this striking plant with hairy flower heads and top of stem. Don Sutherland commented: "This is Nabalus racemosus (formerly Prenanthes racemosa) with the accepted English common name Glaucous Rattlesnakeroot (aka Glaucous White Lettuce)."

 

Foxtail Barley

 

The marsh at camp contains lovely patches of Alkali Bulrush (Bolboschoenus maritimus ssp. paludosus), which is abundant in Ontario along the James Bay coast, but rare on the Hudson Bay coast. It also occurs locally in southwest Ontario around Lake St. Clair where it is found in salt-rich habitats. (Don Sutherland pers. comm.). This attractive bulrush was first pointed out to me by Riley Walsh.

 

Wolf-willow (Elaeagnus commutata) is common on sand dunes and along river shores from the Hudson Bay coast south locally to the north shore of Lake Superior and Lake Timiskaming. Not a willow at all, but a native member of the Elaeagnaceae (Oleaster Family), which includes such better-known and aggressive alien species as Autumn-olive (E. umbellata), Russian-olive (E. angustifolia) and Sea-buckthorn (Hippophae rhamnoides). (Don Sutherland pers. comm.)
