Climate change is shifting when Toronto’s leaves fall, leaving yard-waste pickup out of sync. If you miss collection:
“Leave a layer of leaves throughout the winter so they can provide habitat for species.” – Melina Damián, Ontario Nature

Autumn leaves are dropping later every year due to climate change. Is Toronto’s yard waste collection falling behind?
Leaves may be sticking around longer than usual this fall due to a “very strange year for trees,” experts say. Here’s why, and what it means for you.

Willow Beaked-gall Midge

iNaturalist

The larvae of this midge form galls as they develop in the terminal buds of willows. They overwinter in these galls and emerge in the spring as adults.
Willow Beaked-gall Midge iNaturalist The larvae of this midge form galls as they develop in the terminal buds of willows. They overwinter in these galls and emerge in the spring as adults. In studies performed on Salix eriocarpa, it was found that plants colonized by the willow beaked-gall midge are stimulated to produce greater numbers of lateral shoots. This younger secondary growth in turn leads to increased herbivory by aphids such as Aphis farinosa and leaf beetles such as Plagiodera versicolora and Smaragdina semiaurantiaca

Red Squirrel

The scientific name is Tamiasciurus hudsonicus. The Latin word “Tamias” means “storer” and “sciurus” means “shadow of a tail”. To the Ojibway Indians, the red squirrel is known as “Adjidaumo” meaning “tail-in-the-air”.

Ontario is dismantling 36 conservation authorities and replacing them with 7 regional bodies. Not for efficiency, but to strip power from communities and impose top-down control.

The Doug Ford government is setting its sites on conservation authorities for the fifth time, merging the watershed protection agencies. Staff tell @fatimabsyed.bsky.social it may ‘slow approvals, create confusion’ — not to mention it's leaving them with ‘whiplash.’ thenarwhal.ca/ontario-cons...

Parts of Highway 401 span 18 lanes and for wildlife, that’s an almost impossible barrier. With thousands of animals killed every year, we urgently need safe wildlife crossings along the 401. 🌿🐾

Birds Canada recently received a contribution from the Canadian Space Agency through the smartEarth initiative – but what have birds got to do with space? NatureCounts uses satellite imaging to map routes and plot birds. The app is a game-changer for birds – this grant will help us expand our tools!

The Provincial Government's plan to cut Ontario’s conservation authorities from 36 to 7 could threaten watersheds and communities. 🌊 Ontario Nature has made recommendations to protect these vital wetlands.

And now for something completely different!! Who wants to come learn about Trumpeter Swans? Mark your calendars and come join us! Trumpeter Swan Conservation Ontario (a 100% volunteer run charity) will be at the annual “Christmas at Ken Reid” festive event on Saturday December 6 from 10 am – 4 pm, This is a free holiday event for everyone held at Ken Reid Conservation Area, 10 minutes outside of Lindsay and 45 minutes from Peterborough. Hundreds of trumpeter swans within 90 minutes of Ken Reid Conservation Area call this part of the province home. The swans summer here, some winter here, many raise their families here. Come and learn their story. Bring us any tag numbers you’ve seen on the swans, and we will share what we know about them. Share with us where you have seen Ontario’s trumpeter swans. Many of you may not know – before creating @cleanuppeterborough – I was actively involved with multiple organizations protecting animals, nature and the environment. My personal “spark” swan was R39 who I first saw in February 2020. Almost six years later – I have been involved in some rescuing and tagging activities, monitoring swan families and leading area census counts. If you have ever been curious to learn more – this is the place to do it. Come meet the amazing Board members and volunteers who work tirelessly to protect these beautiful creatures! We will be collecting “Toonies for Trumpeters”, so save your toonies and bring them along. Our 2026 Trumpeter Swan calendar will also be available. You can even compare your wingspan to that of a trumpeter swan! Visitors can also look forward to visits with Santa Claus, horse-drawn wagon rides, a Christmas scavenger hunt, Kids’ Craft Corner, story walks, and live music throughout the day. For more information about trumpeter swans and to report where you’ve seen them, please consider joining our Facebook group, Trumpeter Swan Conservation Ontario.
