A national assessment of urban forest carbon storage and sequestration in Canada

Table 2 Canadian ecozones with population centres of greater than 30,000 people and the communities within that have i-Tree Eco projects with available data that were used in this study

Atlantic maritime (NB, NS, PE)	19,736,815	113,600	Halifax
Boreal plains^a (AB, SK)	67,185,834	18,100	None
Boreal shield east^a (NL, ON, QC)	99,129,131	90,600	None
Boreal shield west^a (ON)	71,111,613	18,300	None
Mixedwood plains (ON, QC)	11,014,617	855,700	Ajax, Aurora, Bolton, Brampton, Caledon, London, Markham, Mississauga, Oakville, Pickering, Richmond Hill, Toronto
Montane cordillera (BC)	47,226,428	52,600	Kelowna
Pacific maritime^b (BC)	20,487,877	199,100	Seattle
Semiarid prairies^c (AB, SK)	23,493,794	60,200	None
Subhumid prairies (AB, MB)	21,598,791	250,000	Calgary, Edmonton

^aCarbon values for Canada’s managed boreal forest from Kurz et al. [10] was used for the Boreal ecozone urban forests
^bSeattle was used to develop carbon values for the Pacific Maritime ecozone since no Canadian data were available and because it represents a large proportion of the urban area in Canada
^cThe Subhumid Prairies were used to develop carbon rates for the Semiarid Prairies
