Welcome to the City of Peterborough’s Urban Forestry website. Follow these pages for news and events relating to the management activities of Peterborough’s urban forest, as well as information about the issues we all face in keeping our private and public trees healthy.


Tree Conservation within the City of Peterborough

The City of Peterborough has recognized the environmental, aesthetic and public health benefits that  trees and the Urban Forest provide to the entire community and wishes to regulate the removal of healthy trees and ensure their replacement through the Tree Conservation By-law and the  Woodland Conservation By-law. The new By-laws regulate the destruction or injury of healthy trees on private property, including Woodlands, and are effective as of October 23, 2017.

Peterborough’s Urban Forest

The urban forest, or green infrastructure, of a city is comprised of both private and publicly-owned trees. In fact, over 70% of the urban forest is privately owned. The City of Peterborough is the custodian of its urban forest and plays a key role in maintaining the tree canopy through maintenance, planting, removal, and pest management programs for publicly-owned trees. As stewards, Peterborough and its citizens value the urban forest as an important part of the City‘s green infrastructure. We must manage this resource proactively to maintain and promote the many social, economic, and environmental benefits derived from our urban forest.

Emerald Ash Borer Alert

Peterborough currently faces a threat to its public and private ash tree resource. An invasive and exotic insect pest known as the Emerald Ash Borer (EAB) has infested many ash trees throughout Southern Ontario. In the spring of 2013, with the threat of this pest at Peterborough’s doorstep, the Peterborough’s City Council approved the Emerald Ash Borer Management Plan to mitigate the impact of EAB. Ash trees are a significant component of Peterborough’s urban forest and represents about 10% of the total City-owned tree canopy. Ash trees have also been a popular choice for planting in many private property landscapes within the City.

Facing a complete loss of ash trees as a result of EAB, the City of Peterborough will need to consider carefully the value of the urban tree canopy and determine how best to manage and compensate for the loss due to EAB.

Through the EAB Management Plan, Urban Forest Specialist, Paul Hambidge, is leading a complete inventory of the City’s ash trees to better understand the true management costs for selective treatment and removal of publicly-owned ash trees.
