Canada

Canada: 44 ecoregions. Each with its climate now and toward 2050, and its conservation tier.

Landscape and climate

Forty-four ecoregions cross Canada, and the pattern is dominated by cold: a broad belt of boreal forests and taiga (Eastern Canadian Shield taiga, Midwest Canadian Shield forests, Mid-Canada Boreal Plains forests) grades northward into the Canadian Low Arctic tundra, Canadian Middle Arctic Tundra, and Canadian High Arctic tundra. South of the boreal line the country diversifies - Northern Shortgrass prairie and other temperate grasslands on the Prairies, New England-Acadian and other temperate broadleaf and mixed forests in the southeast, and conifer forest along the Pacific. For gardeners this means short seasons and deep winter cold nearly everywhere, with the mildest, longest-season pockets confined to the southern margins. Hardiness and bloom timing, not summer heat, are the limiting questions for most Canadian plantings; spruce, birch, and other boreal-adapted natives set the baseline palette.
