Thank you to all the many members and the Board of the
Ontario Chapter of the Society for Ecological Restoration.
It was fun and valuable to have foresters, botanists, landscape architects and biologists
lend a muddy hand to the first plantings at the wetland.
The plants chosen were the heavy duty maintenance types of plants
which are quite reliable and hold soil and
stabilize the site quickly.
All of the plant material is indigenous to this area:
Shining willow (Salix lucida)
Autumn willow (Salix serissima)
Red Osier Dogwood (Cornus stolonifera)
Softstem bulrush (Scirpus validus)
Burreed (Sparganium curycarpum)
Broad-leaved Cattail (Typha latifolia)
River Bulrush (Scirpus fluviatus)
Arrowhead (Sagittaria latifolia)
Water Smartweed (Polygonium amphibium)
Buttonbush (Cephalanthus occidentalis)
Common three-square (Scirpus americanum)
Seed of Awl-fruited sedge (Scirpus americanum),
a Fox sedge (Carex annectans)
and Black Bulrush (Scirpus atrovirens)
were scattered one week later on October 22.
In addition, two Sycamore trees (Platanus occidentalis)
were donated by the City of Toronto (thanks Friends!).
We are busy planning the viewing stand and signage for the new wetland
as well as planning for the big party in September.
If you would like to help with planning
for the party please let us know.
Todmorden Mills is a restored historic village in Toronto's Don River valley. The site was first
established as a lumber mill in 1794, later becoming a thriving paper and grist mill and a brewery
until 1916. The fifteen-acre natural area is the remnant of Helliwell's Bush, named for one of the
early owners. This natural area was designated the Todmorden Mills Wildflower Preserve in 1991
when a volunteer committee was formed to begin restoring the woodland.
Habitats include a wet and dry meadow, riparian and upland forest, and a wetland in the old Don
river channel. Historic accounts list the species found there as "massive" elms and sycamore;
basswood, butternut, walnut, crab apple, black cherry, bur oak, and white cedar, with an understory
of grape, currants, gooseberry, prickly ash, and trilliums. The slopes surrounding the site were
towering white pine forests.
The site has changed significantly from the old days through dumping of fill, forest clearing, planting
or seeding-in of exotic species, and an expressway that now separates the site from the river. Salt
spray from the expressway is a constant problem. Meadow areas are largely exotic legumes and
grasses. The forest is predominantly Manitoba maple, crack willow, black locust, and european
alder. Garlic mustard, common buckthorn, Norway maple, and dog-strangling vine are invading the
understory of alternate dogwood, choke cherry, ash, zigzag goldenrod, avens, and Virginia waterleaf.
Without the exotics, natural succession would probably have restored the site long ago. They are
being removed slowly but present an ongoing problem with the modest resources available to control
The restoration is being carried out by a volunteer committee headed by Dave Money, past president
of the Ontario Horticultural Association (OHA). The goal is to restore the vegetation to pre-settlement conditions
as much as possible. The volunteers work a half day per month to do
plantings, weeding, plant rescues, trail clearing, and site preparation for plantings. Local residents
donate plants they find growing in their gardens, Metro Parks grows some meadow species, and the
Canadian Wildflower Society has been a regular contributor. A partnership has been established with
the Rotary Club's Ecosystem Education Program to assist with planting, and some sustaining funding
comes from the Toronto district of the OHA.
The focus has been on planting native wildflowers in the meadows and forest understory, with some
trees planted in the dry meadow as a barrier. Many of these plants are rescues from highway
construction. Trillium, michigan lily, trout lily, marsh marigold, jack-in-the-pulpit, mayapple,
shagbark hickory, sugar maple, walnut, and a wide variety of others have been planted in appropriate
Dr. Mark Taylor, a noted Toronto biologist has prepared an overall concept plan for the site. A
wetland enhancement will begin in fall 1994 to increase diversity of the aquatic habitat. The next
step will be to deepen and replant the old river channel, now mostly Reed canary grass.
