Invasives 101: Canada Thistle

Great work! Thank you!

I was surprised to see several garden types recently in a local ecopark I was doing an invasives audit on.

Canada lily (Lilium canadense), wood lily (Lilium philadelphicum), Lilium superbum are all indigenous and wonderful alternatives.

Developed by Invasives Canada and Animal Health Canada, in collaboration with the Invasive Wild Pig Leadership Group, this new resource supports efforts to address the spread of invasive wild pigs in Canada.

It will take All Hands On Deck to prevent invasive mussels from damaging our lakes and rivers. Boaters, anglers, cottagers, divers… everyone has a role to play.

The UN Environment Programme logo is in the top right, and white text reads “Indigenous Peoples are too often the unsung heroes of conservation.”

Indigenous Peoples make up less than 5% of the world’s population, yet they protect significant amounts of global biodiversity.

#IndigenousPeoplesDay 🌏🧪

A vibrant moment from the Chumash Day Pow Wow and Inter-tribal Gathering at Malibu Bluffs Park, celebrating 24 years of tradition. A participant in traditional attire, adorned with colorful feathers, intricate beadwork, and a bright floral headband, performs a ceremonial ritual surrounded by smoke, reflecting cultural richness and spiritual connection.

Indigenous and local knowledge can shape transformative change.🌏🧪

Many Indigenous Peoples and local communities have views and practices aligned with a just & sustainable world. Their ethics of care and values inspire equitable & inclusive change.

We fully support the Premier. The drought has resulted in extreme risk of wildfire.

The Nova Scotia Invasive Species Council will resume activities when it is safe.
