[CANUFNET] A Quick Urban Street Tree Inventory for Municipalities

[rosswein at shaw.ca]

Hi Andy 
I am exploring the protection status of rare and endangered plant species in Edmonton where we are fortunate to have the protection afforded by the North Saskatchewan River valley. Outside of the valley, naturalists are salvaging genetic material ahead of the rapid subdivision and industrial expansion. We do not yet have an official list of these species in Edmonton or well developed goals for these efforts. 
I am seeking information from other Canadian urban centres that have developed policies, procedures, and research that ensures the protection of these rare and endangered species. 
I look forward to hearing from members in the network.
Cheers
Ross

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.
