Tree inventory
Tree inventories are an essential tool to protect and enhance urban and rural forests which helps ensure healthy forests for generations to come. They are useful to help maintain diversity in the street tree population, assess the health of the urban forest, and communicate with property owners. Inventories need to be updated regularly in order to help schedule tree maintenance work, determine planting sites, and manage invasive insects. The inventory of city-owned trees began in March 2009 and once completed it will contain information on over 300,000 street and park trees, woodlots, ravines, and community forests. Information such as species, diameter, health condition and GPS location is gathered on individual street trees and downloaded into a database where the records can be extracted and mapped to provide information on the number of different types of trees on a particular street. New tree data is collected on an ongoing basis as tree inspections or routine tree maintenance work is completed.
The dataset provides an inventory of City-owned trees located on the road right-of-way, and in parks. Some privately-owned trees are also collected by Forestry staff are included the dataset for reference. The dataset should not be used for ownership verification. Not all information has been verified for precision or accuracy and therefore should only be used in an advisory capacity. Forestry Services reserves the right to revise the data pursuant to further inspection or review.
The Tree Inventory dataset is available on the Open.Ottawa.ca site, or can be viewed in geoOttawa. Tree Inventory data is made available with the Open Data Licence Version 2.0.
