Web

Back to the web version

The information on this page was developed from the literature listed below by staff at the city of Ottawa's Central Parks and Forestry Services department.  Where there were differences in the listed tolerances among the articles an average tolerance was calculated for each species. Thanks to Craig Huff, Forester, City of Ottawa and the City of Ottawa's Forestry Services as the source of and permission to publish the list above.
