The Northern Rockies conifer forests cover the southeastern British Columbia interior, much of western Alberta, and the northern Idaho / western Montana panhandle — the wet 'inland temperate rainforest' on the windward slopes plus drier Douglas-fir + lodgepole pine forests in the rain shadow. Notable as the only inland temperate rainforest in the world; western red cedar, western hemlock, and grand fir at low elevation are climatically anomalous for the continental interior.

About the temperate conifer forests biome

Temperate forests dominated by evergreen conifers, from coastal rainforests to montane pine and fir stands. Adapted to cool, moist or seasonally dry climates, they include some of the tallest and longest-lived trees on the planet.

What's native here

Catalog plants whose Lady Bird Johnson Wildflower Center native-distribution range overlaps the 4-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.
