New city council and our river valley
Campaign platforms and surveys give some indication about what Edmonton’s new city council thinks about river valley concerns and issues. Edmonton River Valley Conservation Coalition had a lengthy 10 question survey, which can be found on their web site, that five of the elected Councillors answered.

In response to Taproot Edmonton’s question “Do you think city council should have approved Epcor's E.L. Smith Solar Farm”, Mayor Sohi and ten Councillors said “No, I support solar power but that's the wrong location.” Only Sarah Hamilton, who voted in favour of the project, said yes, and no response was received from Karen Principe.

Mayor Sohi promised to ensure Indigenous traditional knowledge informs the preservation and restoration of our natural spaces, including the area around Rossdale and any development that might occur in that area. He also committed to advocate for the full Big Island-Woodbend area in southwest Edmonton to be protected through provincial action in collaboration with the Enoch Cree Nation.

Sohi pledged to work with key partners, including Indigenous communities and regional municipalities, to engage the federal government in creating an urban national park in Edmonton. He said, “The designation of our river valley as a national park will allow us to access federal funds for its protection and elevate our valley’s deserved national reputation.” Read Mayor Sohi’s Embracing Our Natural Environment commitment at https://sohi.ca/policy-embracing-our-natural-environment/

Will wild pigs enter Edmonton’s river valley
Parks Canada has confirmed that wild pigs, which tear up landscapes and eat everything from roots to bird eggs to deer, are present in Elk Island National Park, the only fully fenced national park, located about 40 km east of Edmonton.

According to University of Saskatchewan researcher Ryan Brook, it is only a matter of time before we start seeing the animals, which are a hybrid of domestic pigs and European wild boar, move into cities and towns. A Government of Alberta January 2021 map shows confirmed boar sightings in municipalities and counties adjacent to Edmonton’s western, northern, and eastern boundaries.

There are no native pig species in Canada. Wild boar were imported to Canada in the 1980s and 1990s to be raised on farms but they escaped into the wild and have adapted for forest, wetland, and riverbank habitats

They are large, up to 300 kg, very furry, and make pigloos in the snow to stay warm during the winter season. Pigloos are made by the pigs mounding cattails and burrowing deep into the snow caught by the cattails, creating tunnels within it, and using the snow as insulation.

Wild pigs are reproducing quickly and expanding their range extensively. Their combination of wild and domestic traits, including their high tolerance for cold and ability to birth large litters, “may have bred super pigs,” says Ryan Brook.

Indigenous Peoples Experience at Fort Edmonton Park
The Indigenous Peoples Experience is a new exhibit that opened this summer at Fort Edmonton Park. It is part of a $165 million enhancement project at the river valley park that includes new streetcar tracks and new attractions added to the midway.

The exhibit is an immersive and comprehensive exhibit. It explores the rich and beautiful cultures of First Nations and Métis Peoples while encouraging visitors to seek out the truths as lived by Indigenous Peoples before and after Canada became a country.

Considering September 30 marked the first National Day for Truth and Reconciliation, now is the perfect time to take a walk through the different parts of this exhibit, which include an outdoor hike, a short film about residential schools, a museum detailing the history of Indigenous peoples in Alberta, and a shop with local Indigenous vendors.

The event is open every weekend from noon to 4 p.m. until December, and tickets cost $20 per adult. More at https://www.fortedmontonpark.ca/learn/blog/post/the-indigenous-peoples-experience

Porcupine can swim because of its hollow quills
Porcupines are creatures who slowly, quietly wander our river valley. When the lighting is right, a porcupine's yellow guard hairs give the illusion of a glow all around them. Their quills are hollow, reducing their weight, and making them buoyant swimmers!

This animal's quills are their only defense. It hunches its back with all the quills standing up and lash its tail as the threat approaches. When the predator gets hit by the porcupine’s tail, the barbed quills stick in the predator’s skin and come out of the porcupine.

Historically, First Nations people used porcupine quills to decorate clothing and other objects. Porcupines were also an important source of food. Because of their herbivorous habits, they're usually found in vegetated riparian habitats like mature forests along rivers.

Porcupines keep forests healthy by eating mistletoe, a parasite of trees, and thinning out dense stands of saplings. They climb trees to forage for food. In the summer they eat leaves of trees, shrubs, and plants. In the winter they eat inner tree bark, buds, twigs, and evergreen needles.

Sometimes porcupines chew on leather, bones, and antlers for salt, and to hone their incisors teeth, which can grow 1.5 mm weekly. They are not very social and spend most of their time alone. However, they may share a den in the winter and sometimes forage for food in groups. More at https://www.ealt.ca/species-spotlight-list/porcupine

Beaver in the river valley
Alice writes “I have a naturalist question that might be of interest to other readers: Walking along the trails close to the river edge in the Buena Vista Park area, I have seen a number of trees that seem to have been gnawed on by beavers, a couple were still standing with the distinctive tooth mark chiselling. Surely beaver aren’t trying to dam the North Saskatchewan. Are there in fact any beaver in our river valley? What would they be up to here?”

Where solar energy is a conservation loss
This title begins a 5-page article in the Summer 2021 edition of the Alberta Wilderness Association Journal. The photo of Epcor’s solar power plant construction in the river valley was taken by Eric Gormley on Thanksgiving weekend.

Our society’s position is green energy should not be produced at the expense of Edmonton’s ribbon of green. This project should not have been approved.

The AWA Journal article highlights the work of the Edmonton River Valley Conservation Coalition which filed for judicial review of City Council’s October 2020 decision. The judicial review of Council’s decision will occur November 19.

The grounds for the case arise from a June 2019 Council motion. The first part of that motion required additional engagement activities with the Enoch Cree First Nation. The second part of the motion is the focus of the judicial review application.

It asked for the “work and reporting necessary to allow Council to fully consider whether the location within the River Valley should be deemed essential by Council.” The Coalition thinks Council simply ignored the findings of the work and never did what the motion required, deeming that the project was essential in its river valley location.

flycatcher.jpg

Alder Flycatcher banded in river valley
The Alder Flycatcher is a rather indistinct olive-green bird with bold wingbars and a distinctive, raspy song of free-beer! They thrive in open settings such as bogs and beaver ponds, where they sit on high perches and forage for insects by flying out from tree perches to take them from leaf surfaces or midair.

Prey include wasps, beetles, flies, butterflies and caterpillars, and grasshoppers. Wintering birds may include fruit in their diet. Alder Flycatchers build an untidy and bulky cup nest of coarse grass. The nest usually has “streamers’ of moss, cattail, and grass hanging from the bottom or the rim of the nest.

The Alder Flycatcher breeds farther north than any other member of the tyrant flycatcher family. It nests as far north as the Kenai Peninsula in Alaska. Little is known about their wintering habitat, since it is difficult to differentiate Alder, Willow, and other Empidonax flycatchers without hearing their songs.

It ranks 12th in the number of bird species banded at Lady Flower Gardens in northeast Edmonton. Learn more at https://www.allaboutbirds.org/guide/Alder_Flycatcher/id

Edmonton park named after this artist
Paul Kane was a largely self-taught artist known for his paintings of Aboriginal peoples and landscapes, which were based on sketches he made during his travels. The photo is his painting of Fort Edmonton. A park in the Oliver neighbourhood is named after him.

Beginning in 1846, with the approval of the Hudson’s Bay Company, he travelled by canoe, York boat, horse, and on foot across the prairies, the subarctic, and mountains with fur-trade brigades or with hired local guides.

Kane’s mission to record the life of Aboriginal peoples was in line with the Victorian imperialist belief that they were all but certain to vanish in the face of relentless encroachment by Western civilization.

He was the first and only artist in Canada to embark on a pictorial and literary project featuring the Country’s Aboriginal peoples, using the medium of portraiture in a time before the dominance of photography. See more at https://www.aci-iac.ca/art-books/paul-kane/key-works/

Trail south of 167 Avenue temporarily closed for geotechnical testing
The shared-use path south of 167 Avenue, along the west side of the North Saskatchewan River, will be closed for geotechnical testing from October 15 to October 22, between the hours of 7am to 9pm Monday through Saturday and 9am to 7pm on Sunday.

Boreholes will be drilled along the trail to gather information required for the construction of the Edmonton-Strathcona County Footbridge, which is anticipated to start in the summer of 2022. All holes will be restored after the testing is complete.

Borehole drilling will also occur in the Strathcona County Riverside Nature Trail site during this timeline. No trail closures are planned. All holes will be restored after the testing is complete. Up to date information at www.edmonton.ca/edmontonstrathconafootbridge

Saskatchewan Glacier and York boat articles
Mark writes “I much enjoy your weekly report, but you may have a couple of errors in last week's newsletter. First, the implication that the Saskatchewan Glacier is the only glacier that feeds our river. The Mistaya, Howse, and Brazeau rivers (Editor note - which feed into the North Saskatchewan River) all have glaciers in their headwaters.

Second, that the York boat brigades went east in the fall and returned the next spring. My understanding is that they went east or down river in the spring and returned in fall.

Why leaves change colour in autumn
The vivid, often simple colors on the outside are the products of the complex chemistry of growth inside a leaf. Take the yellows and oranges, the dominant colors of aspen, ash, birch and some oaks, these colors come from compounds called carotenoids (also responsible for the color of carrots) which are present in the leaf during the growing season.

The green chlorophyll, the workhorse of photosynthesis, dominates and covers up those carotenoids in summer. As the days grow shorter and the temperatures cool, chlorophyll degrades and goes from green to colorless, allowing the oranges and the yellows to show up.

Trees with gorgeous scarlet, crimson, and ruby fall leaves have another reason for their colour. Red pigments are not present in the leaf during summer. Trees that turn red produce this pigment, called anthocyanin, in the autumn. These pigments play a key role in readying the tree for the next spring.

Researchers discovered that anthocyanins act as a sunscreen, protecting leaves from bright seasonal light when it is cold outside. Other researchers have discovered that the sun screening effect protects leaves from too much light, which can interfere with late-season transport of nutrients from the leaf back to the twigs, something trees do as a conservation mechanism.

Climate change threatens city water source
Warmer temperatures this year had a lasting effect on the glacier that feeds Edmonton’s water supply.

The Saskatchewan Glacier terminus saw 10 metres of thinning this year, said Brian Menounos, Canada Research Chair in glacier change. It is also the glacier that feeds the North Saskatchewan River, Edmonton’s sole source of drinking water.

Matthew Chernos, a Calgary-based hydrologist and consultant, said the high alpine glaciers feeding Alberta’s river systems act as natural reservoirs. While the North Saskatchewan River is mostly made up of rainwater and snow melt by the time it reaches Edmonton, glacier melt is a big part of the river flow in July and August, when the glacier’s winter snowpack has melted away

The scientists were quick to note that fading glaciers also threaten sensitive aquatic ecosystems that rely on cooler water to stay healthy, and the irrigation demands of the agriculture industry.

This deer hide used to make buckskin leather
White-tailed deer are an integral part of a healthy Albertan ecosystem, feeding on plants and serving as prey for many species. They get their name from their tail which has a white underside. When alarmed, they hold their tail upright, exposing the white, as they bound away.

In Alberta, the rut, or mating season, occurs in November. Males spar with rivals, battling each other with their antlers. Fawns are born in early June. Does hide their fawn in tall grass or shrubs when they are first born, to keep them safe from predators. The doe returns every few hours to feed and move the fawn.

Deer are notorious for foraging continuously along the same pathway, so deer trails are well worn and easy to spot. Deer have scent glands between the two parts of their hooves, and on their legs. These scent glands are used to communicate with other deer. Learn more at https://www.ealt.ca/species-spotlight-list/deer

York boat important to fur trade transportation
It is not known how much timber was harvested by early settlers. We can only speculate by paying attention to the variety of uses to which timber was put. York boats, riverboats, gold dredges, ferries and barges were all built at Edmonton on the river flats.

Artist Paul Kane noted in 1846 “40 or 50 men…their employment chiefly is building boats, sawing timber, which they raft down the river from 90 miles higher.” He was fascinated by the prodigious effort needed to keep a supply of York boats.

Kane wrote they are “building the boats, about thirty feet long and six feet beam, which go as far as York Factory, and are found more convenient for carrying goods on the Saskatchewan. . .more than one-half of the boats built here never return. This system requires them to keep constantly building.”

It was a long and perilous river journey from Fort Edmonton to Hudson Bay. Some boats were lost to rough water. Most likely many boats were not sea-worthy after being subjected to the harsh winter elements at the bay. Fur-laden boats left Fort Edmonton each fall and crews could not return with the next year’s trade goods until the following late spring.

Fundraiser for solar farm judicial review
Charles writes “As a citizen of Edmonton for fifty years I am glad to see greater awareness of our river valley, and greater use. The conflicts that come with multiple users, like the Epcor solar farm, always need to be presented to the public.

Consider something about the arts and the river valley. Paul Kane, I believe painted the valley but there is a history of artists being inspired by the valley. This time of the year the quality of light in the valley is spectacular.”
