Thousand Islands Watershed Land Trust

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.

Sharing this great story from our friends at Thousand Islands Life Magazine For 37 years, Bud Andress patrolled nearly 90 kilometers of the River as a Canadian National Park Warden. From harrowing rescues to slow but steady efforts to bring back osprey and bald eagles to the Thousand Islands, his job was never the same from day to day.

Michael Laprade’s new “Interesting Islanders” series for Thousand Island Life Magazine kicks off with Bud’s story. Find the full story at the link in the Thousand Islands Life Magazine bio.

Are you interested in volunteering to help our Head Wildlife Biologist Maggie, with the removal of invasive species?

On Friday Maggie, was working at the removal of seed pods on dog-strangling vines.

Now is the last chance to prevent spread before the seed pods start to open. After the seed pods open the fluffy seeds are very easily dispersed by the wind.

Maggie will be continuing to do this work on Tuesday morning locally at a property in our Thousand Islands Watershed region. If you are interested in helping out with this or with other invasive species work, Maggie would be very appreciative of the help! If interested, you can contact Maggie at [email protected]

Thank you very much to Kathy Baker for sharing these photos she snapped this week while she was volunteering in the gardens at our Glen Elbe Learning Center in Athens.

This is an Aster Bee Fly on an aster! And pink Joe Pyeweed covered in bees!

The other two photos represent our Native plants’ holding bed. Our native plants have been growing and as they are, we are popping the extras into this new holding bed.

Kathy was working with Claudette and Gerry to add plants as they continue to multiply in our gardens and need dividing.

🌼🪻🌺These plants will be potted up and available for the public come spring. We are gradually adding to a selection of native plants and we hope to be a local source for people who are looking to create more native habitats in their own gardens!

Thank you for the photos, Kathy!

We were grateful to have reporter Catherine Orth as a guest in attendance at our Celebrate 4ever Summer Party - Keystone Connections.

After the party, Catherine wrote an article for the Brockville Recorder & Times that carefully addresses our reasons for this year‘s fundraiser - and why we were calling it - Keystone Connections.

Among many of the details in Catherine’s story, we especially liked: “The engine to raise this money was the pre-dinner Auction for Acres and TIWLT executive director Calder Schweiter’s extraordinary energy and passion for his work.”

Please read Catherine‘s whole story on the NEWS page of our website

Thank you to gardening volunteer Robert Burtch, who took these photos at our August 15 Celebrate 4ever Summer Party.

Gardening volunteer Claudette is admiring a male Monarch Butterfly on Joe Pye W**d.

Robert also shares that this photo encapsulates the mission of TIWLT at Glen Elbe. We are providing native pollinators with good quality food/nectar and host plants for larvae so they can continue to thrive in our environment forever!

Thank you Robert Burtch and thank you to all the gardening volunteers at TIWLT that make these beautiful gardens possible!

The Thousand Islands Watershed Land Trust is again – overwhelmed with gratitude!

On Saturday August 15 our local community, from Ottawa to Brockville to Athens to Mallorytown to Gananoque to Kingston, came out in full support and generously donated over $100,000! Not only through their ticket purchases for the event itself, but at our Auction For Acres!

Funds raised will go a long way towards supporting our Keystone Connections Project, which consists of 9 conservation properties throughout the Frontenac Arch / Thousand Islands Watershed, all aimed at connecting existing conservation nexuses in our area.

We cannot even begin to adequately thank supporters. You have spoken up, shared your desire for these areas to be conserved, and put your action behind it!

We also wish to send enormous THANK YOUs to River City Junction, Triola, and chef Dan Thomsposn of the Keystorm Pub, for the wonderful music and delicious food. Party goers were up dancing, and there were many compliments on a wonderful meal!

Thank you to our volunteers, and to the various local media who supported our efforts. You can see some of their stories on our website NEWS page. Thank you also to the individuals and the community groups on Facebook who shared our posts over Instagram!

Please stay tuned for news and announcements to come from this great showing of generosity!

📸 Thank you to JP Timmerman for snapping these photos for us!
