NATURE NEEDS US, AND WE NEED NATURE. WE BELIEVE WE CAN LIVE IN HARMONY. 


THe A2A Region

Our region is special. It lies between and encompasses Adirondack State Park in New York State and Algonquin Park in Ontario. This entire region is part of an extremely important habitat corridor that extends from Florida all the way to the Boreal Forest in the north, known as the Great Eastern Wildway.

The Thousand Islands-Frontenac Arch region, a highly biodiverse area, sits at the pinch-point of the A2A corridor and provides a critical link for wildlife migration across the St. Lawrence River.  

We concentrate on improving ecological connectivity within the A2A region to ensure that nature can flourish and the corridor can function as a resilient pathway for wildlife.​

2022-2027 Strategic plan

Discover our framework for conservation in the A2A region. We're committed to forging a brighter future for wildlife, guided by our core values and a clear vision to create a resilient, ecologically-connected landscape that sustains wildlife and enhances people's quality of life. This plan outlines our programs, values, goals, and the actionable steps we're taking to make a lasting impact for conservation in the A2A region.

Road ecology

In Ontario, we have completed studies to determine optimal locations for wildlife crossings to enable wildlife to safely cross Ontario Highway 401 and other major roadways which parallel the Thousand Islands. This narrow area is the gateway between the north and south sections of the continental habitat corridor; however, the highway blocks wildlife movement. View our final report, aptly titled "Right to Roam," which was recently released in the  fall of 2024. 

On the American side, in Northern New York, we are engaged in active surveys along NYS Routes 12 and 37, situated directly south of the Canadian study area. This study will provide crucial insights into wildlife mortality rates and aims to identify wildlife crossing zones. Our goal is to bolster conservation initiatives within the A2A region and provide safer passage for wildlife movement across the border.​

Pilgrimage for nature

We've established a ~650-kilometre multi-modal trail that stretches from Adirondack State Park to Algonquin Park, with Alice the Moose serving as inspiration. Alice, who had been radio-collared in central Adirondack Park, embarked on an incredible journey all the way to the eastern part of Algonquin Park. She inspired us to create a symbolic and physical link between the two parks to remind people of the important role that connectivity plays in our environment.

Conservation action planning

CAP establishes a framework for developing conservation strategies. It provides a method for planning, executing, and evaluating initiatives. Using it, we identified the expansion of invasive species in the A2A Region as a top priority item. Following that we held an invasive plant workshop aimed at investigating possibilities for collaborative action and funding. We also developed an A2A “lens” which can be used to develop local conservation plans.

Mapping

Over the years, we have completed several mapping projects to evaluate landscape connectivity in the region and identify critical wildlife habitats and corridors to support land conservation, stewardship activities, land use planning, and other conservation efforts. In 2024, we are updating and expanding our 2014 connectivity mapping to identify core wildlife corridors that will sustain multiple species.

invasive species

​Invasive species reduce the ecological integrity of natural areas— a significant issue in the A2A region.  The Ontario Invasive Plant Council is working with landowners and agencies to combat invasive species.  Find out more about the Council and their work here.

the Gananoque River Watershed 

We tested water quality, assessed shoreline habitat, identified aquatic species habitat, and catalogued species in seven of the 17 lakes along the Gananoque River Watershed. We then provided photos and individual reports to shoreline property owners along those lakes. The reports offered suggestions where improvements would benefit water quality and native biodiversity.

See the Stewardship Project Reports here: Phase 1, Phase 2, Phase 3.
