About this file
This is an approved tree species list prepared by the Pittsburgh Shade Tree Commission for use in the City of Pittsburgh's parks and open spaces, in conjunction with the City of Pittsburgh Office of Management & Budget's pre-qualified contractor program for tree planting services. The document establishes guidelines for tree species selection and planting composition, specifying that coniferous trees must comprise at least 20 percent of any planting, with no more than 30 percent of any plant family, 20 percent of any plant genus, and 10 percent of any plant species. Deciduous trees may comprise up to 80 percent of plantings and are subject to the same family, genus, and species restrictions. The approved species list is divided into two sections: coniferous trees (including firs, cedars, cypresses, junipers, larches, pines, baldcypress, yews, and arborvitaes) and deciduous trees (including maples, buckeyes, alders, serviceberries, birches, hickories, oaks, dogwoods, magnolias, and numerous other species). The document was finalized on February 26, 2020, and serves as a reference standard for contractors bidding on Pittsburgh tree planting projects.
The list identifies frequency of use for each approved species (sparingly, moderately, or frequently) and designates which species are stormwater tolerant, providing guidance on appropriate species selection based on site conditions and environmental considerations. The initial contract period for pre-qualified tree planting contractors commences upon execution and terminates on June 30, 2030. All applications for pre-qualification must be submitted electronically to contracts@pittsburghpa.gov in the required PQMA packet format, with electronic submission being mandatory. No pricing terms, set-asides, funding sources, or other financial details are specified in the approved species list document itself, as this serves as a technical specification guide rather than a procurement solicitation or contract award document.
