Tree Action Arbre Working Group
Tree Action Arbre
Growing. Protecting. Greening.

Our vision of Cornwall and the surrounding areas is that of a vibrant and connected natural environment sustained for future generations. To achieve this vision, we will use advocacy, education and greening initiatives.
We welcome new members and seek to engage the community and pursue partnership opportunities with other like-minded groups.
Currently the group is researching and providing resources to help people make informed decisions about the conservation and expansion of tree coverage. We also provide information and resources to individuals wishing to plant trees, conserve natural areas or seek advice about their existing trees.
We are supporting the City of Cornwall through their current process in developing a robust and effective “A Tree Protection by law”.

Tallest Trees Contest
During the months of July and August, 2024, Tree Action Arbre hosted a Tallest Trees Contest for the City of Cornwall. Everybody was encouraged to participate, but the tree had to be found within the city limits. The aim was to encourage people to explore our community to discover its many towering trees, and with that, grow an appreciation for all trees. The challenge was to measure the tree’s height then make an entry. The members of the Tree Action Arbre donated generously to the prize assortment with cash as well as interesting items. Other sponsors include CRUSH LANE, a local goldsmith, the Cornwall Golf and Country Club and FAIRY SWEET, Cornwall’s own Gourmet Bakery.

The excitement was palpable on Saturday at the Tiny Forest @ Library as it was prize distribution time for the winning entries for the Tallest Tree Contest held this summer by Tree Action Arbre group of Transition Cornwall +.
Pictured in the photo from the left are Ainsley Ladouceur, whose maple tree measured 120 feet tall, Kimberly Bray, the five and a half foot tall tree committee member, Neil MacLean, whose poplar tree entry was 95 feet, Lise Lalonde had a pine tree measuring 98, Dan Marion organizer, Mavis Williamson had a 66 foot tall tree in her own backyard, and Lynn Macdonell, organizer.

Absent from the photo is Daniel Besner who submitted an entry for a Poplar tree, which may be found on Bergeron Dr. in Legion Park. It is a magnificent tree which measures 95 feet.

This towering Pine tree, measuring 125 feet, was the winning entry, submitted by John Towndrow. It may be seen on private property adjacent to the Cornwall Hospice.
The prize distribution at the Tiny Forest @ Library was a fun event. Organizer Daniel told about his inspiration for the contest. Kimberly was the apple tree who gave out the winnings.



Maybe you have never looked up, way up at the amazing trees in Cornwall. Well now is the time. This contest is for you or the whole family to participate in together! And if you think you know your local trees, now is the time to test that out. Let’s explore, discover and appreciate this amazingly beautiful natural resource in Cornwall. There are prizes to be won and bragging rights to earn! For this contest, your challenge is to find, identify, measure, photograph, and report the tallest tree you can find.
How do you identify which type of native tree it is? We are looking for the tallest pines, cedars, spruces, maples, birch, oak, aspen, ash, and or butternut. Might you find another native, send in your entry.
You also need to provide the tree’s general location (e.g. the corner of Brown St. and Red Avenue, or half way along the north side of Purple Street between Green and Pink Streets). Make sure your tall tree is within the boundaries of the City of Cornwall
This video might give you some guidance.
Entries are limited to one per individual or family group. This is a correction to the Tallest Trees Contest articles published in the media.
How long do you have to find that tree? The contest lasts for the months of July and August. Winners will be determined and announced in September. Prizes will be awarded as per the tree type submitted.
The aim of the contest is to grow awareness and appreciation of the trees that beautify our city. Get out there and enjoy the search.

It a was a partnership between the City of Cornwall and Transition Cornwall +. A neglected area of the park got an impressive facelift this May. TREE CANADA provided the funds and the Raisin Region Conservation Association provided the trees.
The City of Cornwall donates a new bench to The Tiny Forest @ Library

Transition Cornwall + strongly believes that partners in projects is the way to go. The City of Cornwall has been an amazing partner since the initial stages of the Tiny Forest @ Library. This donated bench was built and installed by the City employees. It fits in beautifully, it sets off the CCVS student created sign, while it welcomes folks to have a seat.
Tiny Forest @ Library acquires an Interpretive Sign
Thanks to the support of the Cornwall Public Library and Transition Cornwall +, the Tiny Forest @ Library now has an interpretive sign. This sign, created by Cornwall City Press, replaces the brochures which were available to the public on a walk by basis. Appreciation goes to John Towndrow who did the installation. It is August 2023, four years after the initiation of the project and the trees are all thriving well, beautifying the downtown of Cornwall.


The Many benefits of the Minuscule but Mighty Miyawaki forests

The many benefits of the minuscule but mighty Miyawaki forests. Pioneered by a Japanese botanist, compact Miyawaki forests are beginning to replace backyard lawns on tiny plots around Canada.

A tree is not just a tree. It is part of a collaboration of living creatures both intricate and mysterious — microbes, fungi, shrubs, ground- covers. In turn, this assemblage attracts insects, birds and mammals in a merry mashup of collegiality.
This refashioned understanding of the tree is giving rise to a tiny, forested revolution in cities across the world, including several in Canada. Rather than planting lawns around a solitary tree — once the ideal — municipalities, homeowners, schools, businesses and others are planting Miyawaki forests.
Named after the Japanese botanist Akira Miyawaki who invented them about 40 years ago, the densely planted forests are perhaps the size of a tennis court, often even smaller. But these minuscule forests are mighty, containing hundreds of plants, each striving to get its share of sun and rain. Done the right way, the forests achieve mature heights in about 20 years, rather than 100 or more, because they grow up rather than out.
“It’s one of those few things that when you first create it, it just gets better over time,” says landscape architect Heather Schibli. Her firm manages CanPlant, an organization that is beginning to track Miyawaki forests in Canada and the native species they contain.
So far, there are nearly a dozen in Ontario and Quebec, with plans in the works for many more across the country. One of them is in Schibli’s backyard in Guelph, Ont. Its 230 woody plants are packed into eight metres by nine, leaving enough room for a back deck, trampoline and shed.
Schibli started by covering her lawn with a layer of cardboard, then adding compost and mulch. Once the forest was planted, she needed to bolster organisms in the soil, a key element of forest life. She took a spoonful of soil from a local wild forest, using it to make a “tea” with which to water the new forest. This tea fosters mycorrhizae, the fungal threads that bind plants together, communicating and sharing food.
The trees must be native and local, evolved to live together. They are chosen to form four structural layers — canopy, sub-canopy, arborescent (small understorey) trees, and shrubs.
The benefits multiply. Trees that grow tall quickly absorb more carbon dioxide than trees that grow slowly, building carbon into root and branch. The forests help manage storm water: Schibli’s neighbours diverted run-off water to her backyard to nurture the trees. Air quality around the forest is better because of the oxygen the plants emit, and all that greenery absorbs noise and soothes the spirit. More species arrive. It’s the recipe for an ecosystem.

Looking for Nature Minded People
Tree Action Arbre is reaching out to the community to ‘grow the group’. All are welcome to attend an open meeting on Tuesday, November 15 at 6:30 at the Cornwall Public Library. See poster below.

Feedback on the Launch from the chair of TC+
It was a really wonderful experience to see the Tiny Forest successfully launched on Friday.
After all your hard work, seeing the City representatives and the local press show up in force was very gratifying.
I think it shows that our efforts are really having an impact so congratulations on a great event and a project that will have such wide-ranging benefits for years to come. John Towndrow

Tiny Forest Coming Soon
Tree Action Arbre member Susan is setting up the pegs indicating where the trees are to be planted in May 2020. The City of Cornwall has sponsored the purchase of 37 trees of 10 native species. Planting will take place dependent on availability of our volunteer crew, respecting Covid 19 physical distancing restrictions.
The fall preparations for the Tiny Forest@Library are complete. Daniel, with a small team of TAA members, and a back hoe, spread compost and wood chips. These were thankfully provided by the City of Cornwall.

Daniel has installed the irrigation system under the materials, all set for tree planting in the spring.

Wednesday, September 25, National Tree Day
To celebrate National Tree Day, the first stage of the Tiny Forest@ Library planting took place. Fourteen grade 7-12 students from CCVS along with their teacher Ms St. Germain were on hand. Tree Action Arbre ( TAA) members were also present to celebrate National Tree Day by planting trees.
The students used shovels, compost, wood chips and lots of muscle to prepare the soil. In all six trees found new homes: four Sumacs and two Columnar Crab apple trees. The grade seven boys were tasked with litter clean up, and they met the challenge with gusto.

New Initiative: Tiny Forest@Library
In the fall of 2019 we will be launching a new and exciting project: Tiny Forest @ the Library. Along with our partners, Cornwall Public Library, City of Cornwall, and Cornwall Collegiate and Vocational School (CCVS), we will be planting a tiny forest of edible and non-edible trees, bushes and ground cover along the east side of the Cornwall Public Library on Sydney Street. The aim is to create a small urban forest to replace the existing bare lawn area. This will provide an educational opportunity and hands-on experience for students and the community at large. It will be an example of the possibilities and value of a forest, even a very small one, for Cornwall citizens, animals, birds and insect life, as well as providing shade as the trees grow. It will be an opportunity to demonstrate that small projects like this are an important step in addressing climate change. Volunteers and students will be tending the forest and monitoring changes and effects.
Monday, November 25, 2019, 7:00
Cornwall City Council will be receiving policy recommendations for the “Tree Canopy and Natural Vegetation Enhancement and Preservation”, at their council meeting. The greening advocacy group Tree Action Arbre will be part of a presentation in spport of this along with Mr. Michael Rosen, president of Tree Canada. Please come and show you care. The City needs to know.

How to Winterize you tree (Velta Tomsons at Ecology Ottawa)
With winter fast upon us and snow already on the ground, you might be wondering – is there anything I should do to prepare my tree for the harsh Canadian winter? There is! This past summer, we gave away 12,000 tree saplings and we want to ensure they all have the best shot at surviving the cold months ahead.
Essentially, you need to tuck your tree in for winter. First, place small stakes in the ground around your tree, making sure they’re at least as tall as your sapling. Next, form a barrier by wrapping chicken wire around the stakes. Then fill this in with leaves or paper strips. You can also tightly but gently wrap the tree in an insulating material – anything from thin cardboard strips, to hemp tree covering material, to any other soft, natural substance.
That’s it! For more detailed instructions, and pictures, please visit our website.
If you have any questions, please reach out. You can email me at this address or Ginette Hupé at [email protected].
