What are the different ecological zones?
The five major Domains were Tropical, Subtropical, Temperate, Boreal and Polar. These were considered to divide the globe into five broad but ecologically valid units for global forest reporting, and the subzones provide more detailed categories where required within a broad zone.

Pennsylvania contains 11 ecoregions and each has its own characteristic climate, geology, topography and biogeography.

How many ecoregions are there in North America?
Level I is the coarsest level, dividing North America into 15 broad ecological regions. These highlight major ecological areas and provide the broad backdrop to the ecological mosaic of the continent, putting it in context at global or intercontinental scales.
What is an example of an ecological region?
Level I ecological regions are: Arctic Cordillera, Tundra, Taiga, Hudson Plains, Northern Forests, Northwestern Forested Mountains, Marine West Coast Forests, Eastern Temperate Forests, Great Plains, North American Deserts, Mediterranean California, Southern Semi-Arid Highlands, Temperate Sierras, Tropical Dry Forests and Tropical Wet Forests.
What are the Level I ecoregions of North America?
Level I Ecoregions of North America (select map for larger PDF version) North America has been divided into 15 broad, level I ecological regions. These highlight major ecological areas and provide the broad backdrop to the ecological mosaic of the continent, putting it in context at global or intercontinental scales.
How many ecoregions are there in the world?
15 broad, level I ecological regions; 50 level II ecological regions intended to provide a more detailed description of the large ecological areas nested within the level I regions; and 182 Level III ecoregions, which are smaller ecological areas nested within level II regions.
Why are there 50 Level II ecological regions?
The 50 level II ecological regions that have been delineated are intended to provide a more detailed description of the large ecological areas nested within the level I regions. Level II ecological regions are useful for national and subcontinental overviews of ecological patterns.
