A Community Tree Nursery Case Study Matthew Erb, Tree Pittsburgh About: Tree Pittsburgh staff will share a case study of their community tree nursery where thousands of seedlings grow for restoration tree plantings across the City. Learn how species are chosen to grow and seed stock is selected and collected by volunteers and how the nursery operates. Staff will also share how education program has been adapted to capitalize on the nursery space and how volunteers are engaged in tree propagation.
