Thousand Islands Watershed Land Trust TIWLT is a Canadian non profit Land Trust within the Frontenac Arch Biosphere in Eastern Ontario Welcome to the Thousand Islands Watershed Land Trust!

We are located at the head of the St. Lawrence River, east of Lake Ontario, in eastern North America. We include the watershed of the Thousand Islands area and north to the Rideau Waterway Land Trust. The Thousand Islands is a natural area of more than 1,800 islands on a shared border with the United States. It is one of the most biologically diverse natural areas in the world. This is due to the Frontenac Arch, a granite land bridge that connects the Adirondack Mountains to the Canadian Shield and the west- east migration on the St. Lawrence River. It is a part of the Frontenac Arch Biosphere, the crossroads of the continent.

🍂📸 Watersheds Canada Do you know why the leaves change colour in the fall? 🍂

As the days get shorter, less and less sunlight is photosynthesized by the leaf. This signals to the leaf to stop making chlorophyll. Once this happens, the green colour starts to fade and the reds, oranges, and yellows in the leaf shine through.

Also, here’s your friendly reminder to leave those leaves where they lie! They act as natural mulch, improve soil health, and benefit countless species of wildlife.

Pearly Everlasting is another beauty perennial grown in the Pollinator Garden at the Glen Elbe Learning Centre, in Athens.

🛍️ Plants will be available for sale in May 2027 at the TIWLT Native Tree & Plant Sale!

A profusion of blooms attract a variety of pollinators from mid-summer into the fall. Pearly Everlasting is a low-mounding, drought tolerant plant.

⬆️ About 2’ tall, it is a lovely foreground accent for taller plants.
☀️ Part to full-sun and average - dry soil is recommended.
🦋 It is a larval host plant for American Lady and Painted Lady butterflies.

⁉️ DYK - the name Pearly Everlasting comes from two distinctive characteristics of the plants flowers:

– PEARLY refers to the beautiful, small pearl-white structure surrounding its tiny yellow flowers
– EVERLASTING refers to how long these flowers retain their shape and colour after they have finished blooming and drieD. They can remain attractive for a remarkably long time!

It was a SPOOKTACULAR 6th Annual Spooky Species tonight at the Glen Elbe Learning Centre in Athens.

A full house of children and their adults explored a treasure hunt of species, face painted, played shadow games, went fishing for invasive species, roasted marshmallows, ate hotdogs, pinned the tale on the Raccoon, and decided which species Dracula should spend the next 10,000 years transformed into!

Thank you to all the children and adults who came out and shared the evening, and your generous donations. Thank you also to the exceptional group of volunteers, and to our education team of Rebecca and Amy who planned a wonderful night.

These delicate little purple flowers are New England Aster. They are native to North America and typically bloom late in the summer and into the fall. They attract many pollinators, including many varieties of bees and butterflies.

They like part sun, and moist soil.

We will be selling the fall blooming NATIVE New England Aster, shown in the photos, at our plant sale in the spring of 2027.

We will be selling these plants among many others from our pollinator garden in May 2027 at our annual Native Tree and Plant Sale. Stay tuned for specific dates and times.

🦝🐢🪳🪲🐛This is a fun Halloween event meant to demystify certain creatures that are typically known to frighten kids. These are often misunderstood animal species that sometimes seem scary or gross. Through a playfully exciting interactive trick-or-treat trail in the gardens, children will encounter each one of our 5 featured creatures (portrayed by our volunteers) and will learn more about them.

Instead of being frightened – they will come to love these important species.

🔥After trick-or-treating at all 5 Spooky Species, there will be a campfire to roast hot dogs and marshmallows 🌭 and other fun games like co****le and photo stations.

👻🔦Kids are encouraged to come in costume, and please bring your own trick-or-treat bag, and a flashlight if you have one.

Children must be accompanied by an adult. There is free parking at the site. NO pets, please.

🎃We look forward to welcoming community members for this Halloween event focused on education through fun and games!
