Hi Andy,

 

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:

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:

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.
