<p class="MsoNormal"><span style="color:#1F497D">I’m not sure if this has been shared on CANUFNET before... if not, please do. It’s a neat tool I just discovered that was developed by NRCan to complete a quick urban street inventory that is based on sampling
10% of the total inventory:<o:p></o:p></span></p>

<p class="MsoNormal"><span style="color:#1F497D">They have already mapped the sample points for many towns/cities across the country, and provide a field sheet for collecting data. It seems to be an inexpensive way for municipalities on limited budgets to estimate
their forest cover. Here is a cut and paste of their general approach:<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN" style="font-size:9.5pt">Most urban centers have thousands of trees within their boundaries; counting and identifying each one would require a tremendous effort. Therefore we have developed an approach that surveys only a
sample of the trees in a city/town, but still allows us to accurately estimate the total number of trees and tree species composition. Surveyors will walk a number of routes (0.5 km in length) that have been randomly located throughout their urban centre,
identifying trees to genus (or to species if possible) as they go. In total, the routes will cover about 10% of the total length of roads in each urban centre.</span><span style="color:#1F497D"><o:p></o:p></span></p>
