Tree Stewards

Community volunteers play a critical role in planting and caring for trees. Cities and states across the country have established training programs and networks to harness the power of community volunteers, whether they are called “Tree Tenders” (Pennsylvania), “Tree Stewards” (Virginia), “TreeKeepers” (Baltimore) or by other names.  This page links you to some of the existing programs active in the Chesapeake Bay watershed, and we hope to see the list grow as more communities and states develop programs.
