Seine River – Royalwood South
Seine River Greenway South Trail

Save Our Seine & Nature Manitoba – July 14, 2015

Backgroound

This list and information was developed for a walk organized jointly between Save Our Seine (SOS) and Nature Manitoba on July 14, 2015.

The South Trail is a 1.8km extension of the Seine River Greenway along the west side of the Seine River south of the Royalwood Bridge and north of Creek Bend Bridge.  A protection plan was started in 2001/2 with the area identified as a 'park' in 2004. In 2007 a trail and sustainable development plan was proposed in collaboration with the City of Winnipeg, Save our Seine, and other groups. The current crushed limestone southern trail was mostly completed in 2011 as part of the ongoing plan (there was an easement issue with the land owner at the south end of the trail which meant the last hundred meters or so took longer to complete).

The Seine River Greenway is a narrow riparian zone that provides a natural buffer along the Seine River into the heart of Winnipeg.  This buffer zone protects the river quality and provides a natural habitat in which wild plants and animals thrive.

Fast Facts

The following few species are just a random selection of plants that may be seen during the walk. There was no real reason for picking these in particular.

Peachleaf Willow (Salix amygdaloides)

This is the largest willow in the prairie provinces, the second largest tree after the Eastern Cottonwood.  This is a short lived, quickly growing tree that is common along the Seine River Greeway.  It has lanceolate pale green leaves with a whitish underside.  The name suggests that the leaves are similar to peach leaves.  Baskets, furniture, mats, chew sticks.  Like all willows salicylic acid (pain and inflammation) can be extracted from the twigs.  Young leaves and inner bark and be used as an emergency food source.  The fast growing tree provides riparian stability.

Tartarian Honeysuckle (Lonicera tatarica)

The Tartarian honeysuckle is a common bush found throughout the Seine River Greenway.  It is an import from Eurasia that was brought as an ornamental shrub.  It is usually an indicator of an area that was a homestead or farm but since it spreads easily shrubs can be found throughout the area.  In the city this shrub has not gotten too out of control but it has the potential to outcompete other native tree species.  There is a suggestion that it may produce allopathic compounds that inhibit other plants from growing.

Absinthe (Artemisia absinthium)

This is an introduced plant that is a relative of sage, it has either bi – or tripinnate silver-grey leaves covered in silver-white hairs.   It is a gorilla species quickly invading disturbed areas, usually it is found along the side of the path or in open areas.  It is one of the flavouring ingredients in the spirit absinthe.   In Europe it has traditionally been used to stimulate the appetite and relieve indigestion.  The name "artemisia" ultimately derives from the Greek goddess Artemis (Roman Diana), but likely the use of the name for this genus is related to Artemisia II of Caria, a botanist and medical researcher who died in 350 BC.  Collect several plants and hanging the leaves in a basement, wardrobe, or other area that you want to hide odours.

Common Milkweed (Asclepias syriaca)

Milkweeds are best known for feeding Monarch butterfly caterpillars and are a important addition to any butterfly garden.  Other uses include extracting the tough fibers for making cords and ropes, and for weaving a coarse cloth.  The fibers are sometimes mixed with fibers of Indian hemp  (Apocynum cannabinum).  Although Milkweeds can be prepared for eating without careful preparation they are also toxic.

Water Smartweed (Polygonum amphibium)

Water Smartweed is a truly amphibious plant being able to live on both land and submerged in water.  At one time the same species was split into two because the morphology of the stem and leaves is quite different.  With genetic testing and just monitoring the plants it is clear that the species is just highly variable.   The plants have been used traditionally as a food source or for a variety of medicines.   Recently scientists found that Smartweed accumulate elevated levels of gold suggesting the plant might be used for bioassay or to help clean up polluted tailings.
