Abstract
This paper describes early results from a survey that was developed to allow rapid, yet reasonably accurate, estimates of street tree composition in Canadian communities. To carry out surveys, participants walk (or drive) a number of 0.5-km routes, identifying all trees within 10 m of the road edge. The number of survey routes in each community was determined such that tree densities could be estimated within reasonable error bounds: ±5 trees/km for common species and ±1 tree/km for uncommon species. Information from this initiative has already supported invasive species risk assessments and urban forest management activities. Full details are available at http://gmaps.nrcan.gc.ca/uts/index.php.
