In the United States, GTOPO30 data were derived from the National Elevation Dataset (NED).  In Mexico, GTOPO30 data were derived from 3&#45;arc&#45;second elevation data from INEGI.  These data were prepared by the U.S. Defense Mapping Agency (now National Geospatial&#45;Intelligence Agency, NGA) using contour lines from the INEGI topographic national map series at 1:250,000 scale.

They are effective for national and regional state of the environment reports, environmental resource inventories and assessments, setting regional resource management goals, determining carrying capacity, as well as developing biological criteria and water quality standards. A Roman numeral hierarchical scheme has been adopted for different levels of ecological regions. 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. Brief narrative descriptions of each level I region can be found in the CEC publication \"Ecological Regions of North America&#45;&#45;Toward a Common Perspective.\" The 50 level II North American ecological regions provide a more detailed description of the large ecological areas nested within the level I regions and are useful for national and sub&#45;continental overviews of ecological patterns. The 182 level III ecological regions, smaller ecological areas nested within level II regions, enhance regional environmental monitoring, assessment and reporting, as well as decision&#45;making.

These revised ecological regions were developed in a meeting between representatives of the three nations and CEC in April 2006 in Newport, Oregon.  </p><p>Ecoregions are areas of general similarity in ecosystems and in the type, quality, and quantity of environmental resources.  The ecoregions in this data set are based on the premise that a hierarchy of ecological regions can be identified through the analysis of the patterns and the composition of both living and nonliving phenomena, such as geology, physiography, vegetation, climate, soils, land use, wildlife, and hydrology, that affect or reflect differences in ecosystem quality and integrity.  All the characteristics are considered when determining ecoregions, but the relative importance of each characteristic may vary from one ecoregion to another. </p><p>Different levels of ecological regions are identified with a Roman numeral hierarchical scheme.  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.  The 50 level II North American ecological regions provide a more detailed description of the large ecological areas nested within the level I regions and are useful for national and sub&#45;continental overviews of ecological patterns.

This map of human impacts was made by combining the threat maps and the vulnerability scores.</p>', 'Halpern et al. 2008. A global map of human impact on marine ecosystems. Science 319 (5865): 948&#45;952.','<p>A comprehensive list of 38 categories of anthropogenic drivers of change in marine ecosystems developed through expert workshops (S1) was assessed for data availability on a global scale. We intentionally did not further subdivide these categories into unique drivers (e.g. each specific type of pollutant) as this would lead to over&#45;emphasis of certain activities when impacts are summed. We limited our analyses to anthropogenic drivers with pre&#45;existing global coverage or those for which we could assemble or develop global coverage. Although many regional&#45;scale data and data with a global scope but incomplete coverage exist for a variety of specific human activities, inclusion of these data would bias global comparisons and so were excluded. Anthropogenic drivers that could not be included are, among others: hypoxic zones, coastal engineering (piers, rock walls, etc.), non&#45;cargo shipping (ferries, cruise ships, etc), aquaculture, disease, recreational fishing, changes in sedimentation and freshwater input, and tourism. For all of these drivers data exist for one or more regions, but none have full global coverage. We also assessed availability of global data for 23 different marine ecosystems and were granted access to or developed spatial data for 20 of these. Data that were included in our analyses are listed in Table S1 and described in detail below.</p><p>Our cumulative impact model follows a 4&#45;step process (Fig. S1). We first assembled the global data for each anthropogenic driver (Di) and each ecosystem (Ej). Second, we log[X+1]&#45;transformed and rescaled between 0&#45;1 each driver layer to put them on a single, unitless scale that allows direct comparison, and converted ecosystem data into 1 km2 presence/absence layers. Third, for each 1 km2 cell of ocean we multiplied each driver layer with each ecosystem layer to create driver&#45;by&#45;ecosystem combinations, and then multiplied these combinations by the appropriate weighting variable (uij) These weighting variables come from an expert survey that assessed the vulnerability of each ecosystem to each driver on the basis of 5 ecological traits (S1). The weighting values (Table S2) represent the relative impact of an anthropogenic driver on an ecosystem within a given cell when both exist in that cell, and do not represent the relative global impact of a driver or the overall status of an ecosystem. The sum of these weighted driver&#45;by&#45;ecosystem combinations then represents the relative cumulative impact of human activities on all ecosystems in a particular 1 km2 cell. Finally, to provide ecological meaning to these relative cumulative impact scores, we used empirical data on the condition of ecosystems to groundtruth our scores. The sensitivity of our results to key steps in this process and further details on the groundtruthing method are provided below.

North  America contains approximately 17% of the world\'s forest area, and is known to be the most diverse region as it consists of all but two global primary ecological zones. This map was developed by the forestry agencies of the three countries: Canadian Forest Service, US Forest Service and the <em>Comisi&oacute;n Nacional Forestal</em> (Conafor). Their collaboration results in an update of the FAO ecological zones data from 2000, based on the CEC\'s terrestrial ecoregion data.</p><p>The FAO ecological zones are based on a combination of climate (temperature and precipitation) and potential vegetation classifications.&nbsp; They are broad areas of relatively homogeneous vegetation, with similar physical characteristics. Some ecological zones (i.e. temperate steppe) contain limited or no forest; areas are considered forested when they have a 10 percent minimum crown cover.&nbsp; Orchards and other fruit tree plantations used for agricultural production are not classified as forests.</p><p>The data were generated by the North American Forestry Commission (NAFC) Inventory and Monitoring Working Group as part of the NAFC\'s reporting requirements to the FAO- Global Forest Resources Assessment. The primary data were re-assigned to the CEC terrestrial ecoregions level III for consistency and integration into the North American Environmental Atlas.</p>','','');
