The Eastern Canadian Forest-Boreal transition is the broad east-west band between the northern hardwoods of New England-Acadian forests and the boreal black-spruce taiga to the north — covering much of southern Quebec, central New Brunswick, and the Ontario / Quebec near-boreal interior. Sugar maple, yellow birch, balsam fir, white spruce, and white birch are the canopy mix; the line between hardwood-dominant south and conifer-dominant north shifts visibly across the ecoregion. The region carries one of the highest projected mid-century warming signals in the temperate Western Hemisphere.

About the temperate broadleaf & mixed forests biome

Four-season forests of deciduous hardwoods — oak, maple, beech — often mixed with conifers, shaped by warm summers and cold winters. Trees leaf out in spring and color in autumn; the generally fertile soils have made these forests heavily settled and farmed.

What's native here

Catalog plants whose Lady Bird Johnson Wildflower Center native-distribution range overlaps the 3-state/province roster for this ecoregion. Distinct from the “suited” section below — these are plants that belong here, not just plants that will grow here.

Grain caveat: native here means “native to at least one state / province this ecoregion crosses,” not necessarily native to this ecoregion's specific habitat. A plant tied to wet meadows that crosses Ontario will surface for any Ontario-spanning ecoregion. Finer per-ecoregion native-status data is a future arc.

Catalog plants suited to this ecoregion

Computed from each plant's stated USDA zone range against this ecoregion's NRCan Plant Hardiness Zone 1981-2010 GeoTIFF published current zone range, with the CHELSA mid-century warming delta applied for the projection. Plants whose stated range falls outside both the current and projected zone end up dropped; the rest land in one of the three buckets below.
