Tree Pittsburgh’s mission is to protect and restore the City’s tree population through community tree planting and care, education and advocacy.
Advocacy plays an important role in ensuring that policies and plans that guide the City (and surrounding boroughs, townships, and municipalities) protect our fragile urban forest.
Our goal is to help residents become informed and inspired to speak out for trees. We have developed a white paper to help you start a conversation with your neighbors, co-workers, and elected officials about the benefits of protecting our tree canopy.
There is a growing body of research that demonstrates just how essential trees are to our quality of life-cooling our city during the hot summer months, helping to reduce water and air pollution, and bringing a sense of calm to our bustling urban life.
With proper maintenance, our urban forest is an asset that gains value as it matures. According to the US Forest Service, as trees grow larger their ability to provide environmental services and benefits increases dramatically. David Nowak, of the USDA Forest Service, demonstrates in his research that, “a big tree does 60 to 70 times the pollution removal of a small tree.”
Unfortunately, Pittsburgh, along with many other cities in our country, has experienced a substantial decline in its urban forest due to a variety of causes including construction, pollution, disease and neglect. Great strides have been made over the last several years to plant and care for publicly-owned trees and to create a greater awareness among Pittsburghers about the benefits that trees provide. Over 1,200 local volunteers have graduated from the Tree Pittsburgh Tree Tender program, and more than 20,000 new trees have been planted along streets, in parks, and along waterway trails by the TreeVitalize Pittsburgh partnership, both demonstrating the renewed enthusiasm for our urban forest.
Our efforts to understand the state of our street tree population and to create a comprehensive strategy to improve its size and condition led us to take the steps to deepen our understanding of our urban forest resource as a whole and to create goals and strategies to efficiently protect, manage, and grow the forest across all City neighborhoods. To that end, the City’s very first Urban Forest Master Plan (UFMP) was completed in June 2012, a 20-year plan to grow and protect Pittsburgh’s tree canopy—both on private on public land.
There are a series of recommendations in the Urban Forest Master Plan that are the solely the City’s responsibility to implement, and it is important to note that both the City Forester, Lisa Ceoffe, and Andrew Dash from City Planning participated in its creation as well as multiple other partners and stake-holders. Further, the UFMP is referenced in the Council-adopted, OPENSPACEPGH plan.
In the short-term, there are a series of “low-hanging fruit” recommendations that can make an immediate and positive impact.
- Respond to pest and disease outbreaks and threats to the urban forest
- Fully staff the Department of Public Works Forestry Division, prioritizing inspectors and administrative support staff
- Promote the enforcement of tree ordinances and zoning code through City Planning and ensure that City-owned properties are up to code
- Prioritize and take seriously the results of the operations review that is currently underway for the Forestry Division–a project of the Pittsburgh Shade Tree Commission.
Respond to Pest and Disease Outbreaks and Threats to the Urban Forest
Pest Susceptibility (2011)
- Asian Longhorned Beetle 1,780,000 Trees (67%)
- Emerald Ash Borer 230,000 Trees (9%)
- Dutch Elm Disease 220,000 Trees (8%)
- Gypsy Moth 175,000 Trees (7%)
The City’s urban forest is already feeling the effects of Emerald Ash Borer and Oak Wilt–with entire blocks of Ash trees being removed and acres of land clear-cut in the parks due to Oak Wilt.
A working group made up of local non-profits, the City Forester, and PA Department of Conservation and Natural Resources has formed and is collaborating to address present and looming pest and disease threats; however, the City must dedicate more personnel time and resources to keep ahead of threats. The UFMP makes a series of recommendations around the issue, and the working group is available to provide a briefing to the administration and recommend a course of action.

Tree Pittsburgh—A Valuable Partner
- Raising funds and managing contracts for the professional pruning of over 1,000 street and park trees (ongoing), facilitating the planting of 20,000 street, park, and riverfront trees.
- Developing and launching the Tree Tender program aimed at fostering advocates and stewards for trees just over 1,200 Tree Tenders graduated to date.
- Coordinating nearly 3,700 volunteers since 2009 to mulch and weed over 10,000 street trees, prune 3,149 street trees–totaling over 9,200 hours.
- Leading multiple demonstration planting efforts across the City including: the streetscape at the August Wilson African American Cultural Center, parking lot retrofits in East Liberty, and boulevard greening in East Liberty.
- Coordinating hillside and greenway restoration projects along the Three Rivers Heritage Trail with Friends of the Riverfront and TreeVitalize Pittsburgh.
- Providing an annual “green” job experience for high school and college students.
- Establishing a community tree nursery with a current stock of more than 8,000 seedlings.
- Leading Pittsburgh’s very first Urban Forest Master Planning process to create a 20-year roadmap for growing and maintaining the City’s tree canopy–including a comprehensive state of the urban forest analysis. Tree Pittsburgh is growing to include a larger staff with a more sophisticated infrastructure so that we can continue both to aid the City Forestry Division in the professional maintenance of city trees as well as to expand programming that gets to the heart of its mission–volunteer tree maintenance, planting, and public education. In an era of increasing environmental awareness and responsibility, we are ready now, more than ever, to take steps to deepen our understanding of our urban forest resource as a whole and to create goals and strategies to efficiently protect, manage, and grow the forest across all City neighborhoods.

We observe a disconnect, internally between City agencies and externally with partners that hinders efficiency and capacity and often results in missed opportunities.
- Convene a summit of all agencies with a major impact on our urban forest to formalize communication methods, identify cooperative projects, and seek synergy.
- Formally describe urban forest management responsibilities across all agencies and partners. With a clear division of labor and articulated responsibilities, workflow will more smooth and efficient.
- As long as urban forestry responsibility and funding are divided among various agencies, the City should ensure the means to increase interdepartmental communication and cooperation for plans and projects that may affect the urban forest.
- Identify cooperative projects that connect private landowners to the City’s urban forest goals.
- Perform a comprehensive operational review of the City’s Forestry Division.
It is no secret that some Pittsburgh neighborhoods have more trees than others, nor is it a surprise that wealthier neighborhoods have more trees, in better condition, than economically distressed neighborhoods. While the fact remains that all City neighborhoods have their share of forestry needs, the Urban Forest Master Plan addresses tree canopy distribution issues with a series of recommendations, and the City has a clear role to play in ensuring that all Pittsburgh residents benefit equally from the urban forest.
- Give priority for urban forestry and outreach activities to disadvantaged communities that are currently gaining the least benefit from the urban forest.
- Prioritize neighborhoods for future tree planting and protection efforts to increase deficient tree canopy figures and allow for more equitable canopy cover across the City.
- Respond to resident requests for trees rather than property owner requests.
- In neighborhoods with long-term vacant properties, respond to adjacent residents’ requests to plant trees in front of the vacant properties.
- Do not allow absentee landlords to veto tree planting on adjacent public property.
According to the 2012 State of the Urban Forest Report, the City’s tree canopy cover is at 42%. While this number seems robust, most of the tree canopy is located in parks, hillsides, and vacant properties. These trees provide substantial benefits to City residents, but they do not provide the same benefit as trees planted within communities. Neighborhood trees provide shade to homes and businesses, capture stormwater before it hits impervious surfaces, and bring beauty and a sense of place to communities. We must balance the protection and restoration of our natural areas with the proactive planting and care of neighborhood trees.
- Utilize the UTC analysis in conjunction with the i‑Tree analyses to increase awareness about the relationship between trees and environmental quality and to engage stakeholders in tree planting.
- Set a goal to maximize street tree stocking levels.
- Target parks and other public land to maximize possible canopy coverage.
- Adopt performance-based planting strategies by selecting species based on desired benefit outcomes rather than canopy cover alone.
- Design a backyard tree planting and tree care toolkit for private landowners interested in planting trees to increase benefits that guide people to choose species and planting locations that maximize benefits.
- Share established tree canopy goals and share the UTC analysis with stakeholders concerned with the urban forest.
- Budget adequately to maintain trees after planting.
- Generate positive canopy impacts on small-scale development and redevelopment projects by incorporating canopy goals into municipal landscape requirements for streetscapes, parking lots, and other sites.
- Reassess the City’s urban forestry program budget in terms of achieving street tree and UTC planting goals, the recommended seven-year preventive maintenance cycle, and the young tree maintenance programs.
- Sustain established partnerships and create new partnerships as a means to leverage resources needed to accomplish urban forestry goals.
- Increase penalties for developers and builders who damage trees and ensure enforcement.
- Regularly monitor public trees for maintenance needs, risks, and pests.
- Develop a protocol that provides for regular updating of the public tree inventory.
- Implement a cyclical maintenance schedule of all street trees that provides for a seven-year cycle of inspection.
- Ensure that cyclical maintenance includes pruning of medium-sized and large trees to reduce risk and extend the productive life.
- Ensure that cyclical pruning also includes care for newly planted and young trees in their formative years.
- Communicate and engage with the community regarding the urban forest plan.
- Ensure the Tree Tender program continues so that the City can narrow its focus on mature tree care
- Facilitate a systematic tree maintenance program for public trees.
- Maintain an updated tree inventory with risk rating data that utilize the tree risk assessment standards in ANSI A300 (Part 9) and the Best Management Practices published by the ISA that address both tree inventories and tree risk assessment. [63, 64, 65]
- Create a prioritization scheme in the public tree inventory that rates trees based on risk levels.
- Use qualified individuals such as ISA Certified Arborists to monitor public infrastructure improvements for potential increase in tree risk and to identify potentially high-risk trees as part of regularly scheduled inventory updates.
- Perform re-inspections after storms that include heavy winds or snow that may increase branch loading.
- Promptly remove and prune trees identified with severe and high risk.
- Integrate a sidewalk repair program with proper arboricultural practices and a permit system that tracks proposed work near public trees.
- Maintain adequate funding levels for risk management using in-house funding or partnerships with nonprofits or obtain new funding stream.
- Identify the highest level, exotic pest threats and develop strategies for monitoring, control, removals, and replanting. Strategies should include information about utilization of limited resources and methods to secure funding to prevent or deal with existing pest issues.
- Utilize existing street tree inventory data to monitor public street trees for high-priority, exotic pest threat zones.
- Educate city staff, stakeholders, and the general public about exotic pest threats and provide information about identification and treatment options.
- Create citizen watch programs to assist with early detection of exotic pests. Dovetail these programs with additional education about urban forestry issues.
- Enforce city codes that require tree planting to be a part of development projects.
- Establish street tree stocking goals for each neighborhood and for the entire City.
- Target natural areas and forested hillsides for restoration planting projects.
- Ensure there is sustainable funding for necessary levels of tree maintenance to grow newly planted trees into safe and healthy, mature trees.
- Track all new tree plantings in an accurate and reliable inventory system to facilitate the use of tree data for research purposes, project costs, maintenance needs, and to evaluate progress towards diversity objectives.
- Update and enforce ordinances that protect existing tree resources both on public and private lands.
- Develop a set of arboricultural standards for all work that occurs near public trees. The standards should apply to permitted work by private contractors and municipal crews who perform any type of work that may impact trees.
- Develop ordinance protection for the City’s forested hillsides.
- Create clear authority with an interagency and interdepartmental communication process for inspection, monitoring, and enforcement of protection of public trees during infrastructure improvements by public agencies, or permitted work on public rights-of-way near public trees.
- Create a dedicated account for funds from remediation and fines that is strictly for funding other tree-related projects.
- Incorporate tree protection best management practices and examples of poor practices in a public outreach campaign.
- Create a private property tree protection ordinance.
