In the ABA area we find 30 ecoregions in the major habitat type Temperate Coniferous Forests, the largest number of ecoregions in any MHT. They are found in the sandy pine-dominated south-eastern US and scattered through western North America, dominating the ecoregions of Oregon, British Columbia, and western Alberta.
To facilitate viewing them as a scrolling list from the menu, the coniferous forest ecoregions are broken up into two groups.
