Today is the day: ALT's annual Day of Giving! Give before midnight and have your dollar doubled to support ALT's work in conserving land, maintaining and improving land's ecological health, providing environmental education to all ages in the classroom and on the land, and partnering with communities on conservation efforts.

It takes resources to conserve, expand, maintain, and improve lands like Dead Man's Hollow, and to provide educational programs to engage all ages with the outdoors.

We hope you'll take the opportunity to support this work so we can keep it up! https://alleghenylandtrust.networkforgood.com/projects/104743-donate-to-allegheny-land-trust

TODAY! You can double your dollar for close-to-home conservation during our Day of Giving!

Since our founding in 1993, we've had the privilege to collaborate with more than 40 communities across our region to conserve nearly 4,000 acres of green space.

Our work has the power to transform communities and our region by protecting green spaces that enhance scenic beauty, provide close-to-home places for healthy recreation and environmental education, protect wildlife habitat, clean our air and water, and absorb stormwater to mitigate flash-flooding and landslides.

Together with your support, we can continue conserving our region’s land that is both nice to enjoy and necessary to protect.

We need your help! We hope you’ll donate during our September 19 to have your gift matched dollar-for-dollar by our Board of Directors.
