The International Observatory of Nature Rights says the town of about 2,000 also became the first municipality in Quebec and Canada to sign on to the Universal Declaration of the Rights of the Tree, which is an international initiative spearheaded by environmental groups.

Its three main core articles state that trees are living beings and a common human good, that life on Earth depends on their existence, and that humans must act in “fraternity and solidarity” with them.

Bourdeau says the new resolution means the town will review its existing rules and bylaws to ensure that trees are protected or replaced if they must be cut down. He also plans to implement measures to further increase the canopy, including offering trees for residents to plant.

“Trees are a true green infrastructure,” he said. “They help reduce urban heat islands, improve air quality, manage precious water resources and protect biodiversity.”

Bourdeau said the move was adopted unanimously by councillors, and appears popular with citizens as well. He also doesn’t anticipate it causing any problems, such as interfering with development, although that’s partly because the town has no more vacant land on which to build.

He says his town is a natural fit to become a tree ambassador. It’s built in the woods, and its citizens value a rural lifestyle. They’re also intimately aware of the damage caused by extreme weather and climate change, after being flooded three times in recent years.

When it comes to fighting climate change, “our biggest ally is the trees,” he said.

Yenny Vega Cardenas, the president of the International Observatory of Nature Rights, says the declaration on tree rights is part of the same push that has seen jurisdictions around the world, from New Zealand to Colombia, grant legal personhood to rivers and other natural areas.

It has also happened in Canada, where Quebec’s Magpie river was granted legal rights by a regional government and the Innu Council of Ekuanitshit in 2021.

• But Vega Cardenas says the tree declaration is special because it acknowledges that a single tree is an ecosystem of its own, which can provide shade, food and habitat for other species.

  “We need to understand that [trees] have dignity and they have senses,” she said. “Not sentiments, but senses … They can feel and they communicate with each other in a very specific way.”

  Karine Peloffy, a lawyer with Ecojustice, described Terrasse-Vaudreuil’s decision as a “very hopeful gesture in the broader movement for the rights of nature,” and said the idea isn’t as strange as it might initially seem.

  “We know corporations have legal personhood and rights and they are definitely not living,” she said in a phone interview. “So if some nonliving things can have legal personhood, what’s stopping living beings from equally getting legal personhood?”

  In her mind, there’s no reason why trees shouldn’t be granted legal status.

  “What do trees do if not standing?” she said. “If anything has standing, it’s a tree.”
