How much should a tree be worth
Along a street in Edmonton, mature trees sit protected by a green fence, near the construction of a new light-rail transit line. Signs affixed to the fence show the value of the foliage: A rosybloom crabapple tree is worth $1,389, while nearby a spruce is pegged at $2,185.

These price tags are somewhat of a common practice in Canada, where an assessment formula is used to determine the monetary value of a tree in case it is damaged or killed.

But forestry and biology experts say those dollar amounts do not fully capture the environmental value of trees in an urban landscape, especially as they play an increasingly important role in helping to deal with the effects of climate change.

Some of the benefits often unaccounted for, particularly in urban centres, include the cooling effect of trees and potential energy savings, their ability to capture carbon and their role in maintaining biodiversity.

2022 Canadian city parks report includes Edmonton
This fourth annual Canadian City Parks report, published by Park People, synthesizes lessons learned from the global pandemic, along with data collected from over 3,000 Canadians who participated in an online survey. Top trends this year were a continued interest in park features that support daily life, including dog walking; growing, cooking or eating food; and getting some exercise on a multi-use trail.

Edmonton was highlighted as one of 20% of cities with a biodiversity strategy, one of 53% of cities with a park system master plan updated within the last 10 years, and being above average for percentage of park washrooms that are winterized, with 83% open year-round.

Thirty cities, including Edmonton, participated in the report by providing information. You can check out key park statistics, plans and strategies, and learn more about what made the city's parks stand out this year at https://ccpr.parkpeople.ca/2022/data/cities/edmonton

Nature-based solutions for climate, biodiversity and people
Experts recently gathered to discuss how nature-based solutions can be used to tackle the twin threats of climate change and biodiversity loss. Techniques considered included forest creation or mangrove restoration, which are increasingly appearing in climate strategies.

In theory, such projects could also help to reverse the loss of wildlife, provide economic boosts to local communities and strengthen resilience against climate impacts.

But the topic can be highly contentious because of conflicting narratives around nature-based solutions. The dominant narrative, held by governments and large organisations, is to view nature-based solutions as a useful tool for leveraging nature to suit our needs.

But among Indigenous communities and non-governmental organisations, nature-based solutions are often seen as a dangerous distraction from the need to cut emissions from fossil fuel use, which can perpetuate the existing unjust status quo.

Wondering where to bike, walk or take your dog this weekend
Wayne writes “I would like to clarify misunderstanding that some cyclists have regarding the two-part motion recently passed by Council addressing the use of bikes in our river valley. Councillor Cartmell clarified that, as in the past, bicycles are not permitted anywhere within a designated natural reserve which includes the Whitemud Creek Ravine. Such areas are for foot traffic only. Below is part of Cartmell's clarification:

"The motion passed a couple of weeks ago allows cycling to continue where it has generally been permitted since 1992. With respect to mountain bikes, the motion allows mountain bikes to continue to use established trails, generally trails that have formed an accepted mountain biking network. The motion does NOT allow for new trails to be developed, and does NOT allow for trails to be developed in the Whitemud Creek Ravine. This area is and remains a protected natural reserve."

While most riders are respectful, some mistakenly believe the motion opened the entire river valley to bike riding everywhere. A great many folks with mobility limitations, the elderly, nature enthusiasts and those with young children in strollers, come to areas like Whitemud natural reserve to be able to wander along the trails freely and safely at their own pace.”

Lichens are excellent biological indicators
Lichens are everywhere, unsung, and awesome. Among their many virtues, lichens are excellent biological indicators, sensitive to habitat alteration, climate change, and air quality. How lichens are faring can reveal changes in habitat or environmental factors and give insight into how other groups that are more difficult to survey might be impacted.

Lichenologist Dr. Diane Haughland says, "Lichens have so much to tell us, but we have to know what we’re looking at. Lichens have historically been overlooked and understudied, so a big part of our work is rectifying that."

Diane and other collaborators moved closer to this goal with the publication of “Getting to know our biomonitor neighbours: urban lichens and allied fungi of Edmonton.” One of the first studies of its kind in North America, it covers 114 lichen species detected across Edmonton, including 12 new to Alberta, 2 new to North America, and 5 completely new to science.

Cooking Lake the summer place to be for early Edmontonians
With its cool breeze, Cooking Lake took off as a summer lake destination in 1909 when the Grand Trunk Pacific Line passed along its north shore. Day trippers came out from Edmonton on the morning train east, alighting at the small station of Cooking Lake. Part of the day’s fun was crossing the lake on the motor launch Daisy Girl that operated as a taxi to White Sand Beach on the south side at Ministik, where children built sandcastles before the evening return trip.

By 1916 many Edmontonians had cabins at Cooking Lake. A taxi service was available from the city and motorists increasingly ventured out for the day. More facilities and accommodations were built on the lake shore, which had a graded “lake promenade.” Lunch could be enjoyed at Mrs. McMenomy’s “high class restaurant,” and canoes and row boats hired by the hour.

Larger motor launches were evident on the lake in the 1920s and soon sea planes were landing on its waters, even before a seaplane base was built in 1935. The Cooking Lake Sea Plane Base was used recreationally, as well as by bush pilots returning from the north.

While other lakes around Edmonton enticed vacationers, Cooking Lake remained popular into the 1960s. Water levels and water quality at Cooking Lake have always fluctuated and sailors and swimmers became disenchanted during the 1970s.

Wondering where to bike, walk or take your dog this weekend
River Valley Alliance has created a series of Trek the Trails information guides for the Edmonton Metropolitan river valley that includes Devon, Parkland County, Edmonton, Strathcona County, Sturgeon County and Fort Saskatchewan.

The guides are a mix of short and long routes for beginners or those seeking more of a challenge. All are designed to help you easily explore different sections of the river valley. Information is provided on where to park and how to get to the location; whether bikes and dogs are allowed; condition, difficulty, and length of the trail; route information; as well as maps and photos.

From personal experience, I can attest to the quality of these information guides, having used them to walk all these trails. Trek the Trails is at https://rivervalley.ab.ca/trekthetrails/

Big Island Provincial Park online survey open until August 21
The Government of Alberta has launched public, stakeholder and Indigenous engagement on a proposal to establish Big Island Provincial Park along the North Saskatchewan River Valley in the southwest corner of the City of Edmonton.

Our society has had a catalytic and ongoing role in this initiative. We raised the idea with Mayor Don Iveson in early 2016 and in September 2017 City Council approved a recommendation that the Mayor write to the relevant provincial ministers indicating the City’s interest in the development of an Urban Regional Provincial Park.

The proposed provincial park will be managed cooperatively by the Alberta government, Enoch Cree Nation, and the City of Edmonton. This tri-party partnership approach is a unique model for park development that brings a diversity of voices to the table to help shape the proposed park vision. This approach allows the three governments to co-create a space that is welcoming and inclusive for both Indigenous and non-Indigenous visitors.

The proposed designation of the Big Island site as a provincial park will provide protection for the sensitive river valley ecosystem, including its wildlife corridor and habitat; help to manage and develop recreation and tourism opportunities; provide cultural exchange and storytelling opportunities; and enhance community connections to the river valley. More information, including a map, fact sheets, and online survey at https://www.alberta.ca/big-island-provincial-park-engagement.aspx

Sedges important to the ecology of Edmonton’s wetlands
Sedge is a plant that tends to go unnoticed by those visiting Edmonton’s natural areas. This is partly because sedge does not have eye-catching flowers, and because it is most prevalent in wet areas that are not always easily accessible.

While sedges appear similar to grasses, they are in a different plant family. There is one characteristic of the sedge family that can be used to differentiate it from grasses, and it is best remembered with the phrase “sedges have edges.” If you feel the stem of a sedge plant you will notice it is triangular and has sharp edges, while grasses have a round stem.

Sedges are important to the ecology of Edmonton’s wetlands. Their spreading roots provide erosion control by stabilizing streambanks and provide an environment for the growth of micro-organisms that clean the water of pollutants. The underwater portion of the leaves and stems of sedges provide a habitat for invertebrates, which in turn feed larger organisms, including fish.

Singer and writer come together to tell a story of Edmonton artistically
The third artist pair to take up residence at the Yorath House Artist Studio Placement are Jody Shenkarek and Thea Bowering. During their joint residency at Yorath House, they will begin a long talked-about collaboration that blends Jody’s music with Thea’s storytelling.

Jody Shenkarek is a singer and songwriter, currently leading the band Jody Shenkarek and Hot Kindlin’, and has shared the stage with many local and touring artists over her 30 years in music. She is a member of the Edmonton Potters Guild, a pinhole photography enthusiast and artist, and an accomplished vegetarian chef and former owner of Café Mosaics.

Primarily a fiction writer, Thea Bowering also works in several forms of creative nonfiction. Much of her work is an experimental hybrid of both fiction and nonfiction. She explores the relationship between walking and writing, and themes of memory and trauma, technologization of culture, environment, and intergenerational conflict. Her collection of short fiction Love at Last Sight (NeWest Press, 2013) won the Alberta Book Publishing Award, Trade Fiction Book of the Year in 2014 and was longlisted for the Alberta Readers’ Choice Award.

Jody and Thea have come together to tell a story of the city artistically. On long walks and talks "they will record the sounds of the trails and river, as well as their unfolding ideas about place and nature within the city, their shared history in Edmonton, memory and loss, aging, and finding hope and purpose in this current difficult moment. The long-term goal is to develop and record the material towards an album accompanied by a book of stories and photos." More at

How the City takes a bite out of mosquitoes
Raquel writes “Bti (bacillus thuringiensis israelensis) as used by the city of Edmonton takes out the base of the food chain. The loss of the base of the food chain kills insect eating birds, dragonflies, beetles, spiders, bats, amphibians, and fish. Researchers Carsten Bruhle and Brigitte Poulin found a 50% drop in dragonflies in areas treated with Bti, a 57% drop in spiders, and a 64% loss in beetles.

Germany does not allow use of Bti and other biocides in natural areas. As we are in the middle of a biodiversity and climate crisis, we need to be respectful and realistic about our relationships with mosquitos. Dress properly and protect you own body on mosquito heavy days. Rejoice when you encounter them and celebrate healthy wetlands and biodiversity!”

Eco-Indigenous gardening guide available for free
Judith emailed “I must take issue with the Eco-Indigenous gardening guide. This is a poorly prepared document in terms of the plants suggested and the encouragement of wild foraging in our River Valley! Harvesting and foraging in Edmonton Parkland including the River Valley and Ravine Systems is Illegal - City of Edmonton Bylaw 2202.

The lack of botanical nomenclature leads to much confusion and misleading information. Advocating picking any mushrooms at all can be extremely dangerous and a disclaimer of “Some mushrooms can be toxic...” is not enough information or warning. Mushroom picking should be left to those who know what they’re doing, not the likes of you or me who have no idea which are safe to eat.

I should also like to point out that many people now feel that our natural areas are their untapped grocery stores or pharmacies. They fail or refuse to even think about their negative impacts on the overall eco-system or to individual plant, animal, bird, and insect species that all rely on every aspect of a healthy habitat. Wild harvesting to collect for things like decorative arrangements, medicinal value, or berries for jam or freezing, can have serious impacts on both the target plant species and the surrounding habitat.”
