Newest Professional Paper on Ecoregions of North America
From USGS - SILS Information Bulletin
Professional Paper 1650-E is the latest in the series of professional papers titled:  Atlas of Relations Between Climatic Parameters and Distributions of Important Trees and Shrubs in North America. This edition covers the Ecoregions of North America.
Sample map and data for Northern Pin Oak.
Previous editions include:  Professional Papers 1650-A and 1650-B (SAP # 13796), which together cover the introduction, conifers and hardwoods. These two volumes are only available as a set.
Professional Paper 1650-C (SAP#13797) covers additional conifers, hardwoods and monocots and 1650-D (SAP#206908) covers the Alaska species and ecoregions.
The ecoregion-climate relations presented in this newest report are intended to be useful for a greater understanding of ecosystem evolution, ecosystem dynamics, and the potential effects of future climate change on ecoregions. Climate is the primary factor controlling the continental scale distribution of plant species, although the relations between climatic parameters and species’ ranges are only now beginning to be quantified.
This professional paper examines the relations between climate and the distributions of (1) Kuchler’s “potential natural vegetation” categories for the 48 contiguous States of the United States of America, (2) Bailey’s ecoregions of North America, and (3) World Wildlife Fund’s ecoregions of North America.
For these analyses, a 25-kilometer equal-area grid of modern climatic and bioclimatic parameters for North America was employed, coupled with presence-absence data for the occurrence of each ecoregion under the three classification systems under consideration. The resulting relations between climate and ecoregion distributions are presented in graphical and tabular form.
Professional Papers 1650 A, B, and C are available for free download at: (Search on report number or title). Volumes D and E are being prepared for Internet release.
