The mission of Natural Area Preservation (NAP) is to protect and restore Ann Arbor's natural areas and to foster an environmental ethic among it's citizens. NAP is a division of the City of Ann Arbor. We have public workdays throughout the year to work on various ecological restoration projects, for example: trail maintenance; removal of non-native, invasive plants; trash removal; and collection of native seeds.
