Mission Statement

ACES' mission is to inspire a life-long commitment to the earth by educating for environmental responsibility, conserving and restoring the balance of natural communities, and advancing the ethic that the earth must be respected and nurtured.

The philosophies upon which ACES was founded continue to inspire our daily work. We aim:

To acquire an intimate knowledge of the language of place — that is, to have ecological literacy so the surrounding landscape is perceived as a living, breathing, familiar presence. Knowledge is our goal, in part.
To care by making emotional connections through a wealth of experience in nature and by rationally grasping the importance of diversity and stability of ecosystems to environmental and human health. Caring is an essential element of ACES work.
To develop and share the skills needed to be actively involved in the careful stewardship of our local environment, accomplishing this through hands-on work to protect and restore the balance of ecosystems with which ACES is entrusted. Through knowledge and caring comes meaningful action.

ACES believes these three philosophies inspire a life-long commitment to sustaining a healthy environment.
