 Websites presented in alphabetical order American Horticultural Society Heat Zone Map 
 "The 12 zones of the map indicate the average number of days each year that a given region experiences 'heat days'--temperatures over 86 degrees (30 degrees Celsius)." The site has a Zip Code Zone Finder (1997 data) so users can determine their garden's heat zone and choose plants accordingly. The heat zones complement the well-known system of USDA Hardiness Zones, which measure winter cold in a similar fashion. http://www.ahs.org/publications/heat_zone_map.htm Topics: Plants, Scientific Themes, Weather Last updated Aug 28, 2004 Biodiversity Hotspots
The hotspots described on this site are the "richest and most threatened reservoirs of plant and animal life on Earth." Search, browse by name of spot, or click on the map to access vital statistics; ecosystem, biodiversity, human impacts, and conservation information; a detailed map; and related links. Also includes a glossary. http://www.biodiversityhotspots.org/ Topics: Animals, Biology, Plants, Scientific Themes Last updated Jul 11, 2007 Census of Agriculture
"The only source of uniform, comprehensive data on agricultural production and operator characteristics for each county, state, and the Nation." Includes maps on many agricultural themes, statistics by congressional district, and a database of crops and livestock.

An interactive map of the United States displaying millions of geographical locations in a series of map layers. These map layers display airports, federal lands, urban areas, water features, parkways, rivers, railroads, roads, and geological events. Also includes terrain relief and elevation and seasonal vegetation growth maps, as well as articles about U.S. geography. Map layers and raw data can be downloaded. http://nationalatlas.gov/ Topics: Scientific Themes, U.S. Maps Last updated Mar 1, 2006 USDA Plant Hardiness Zone Map
This interactive document from the U.S. Department of Agriculture shows 10 different minimum temperature zones in the United States, Canada, and Mexico, "each of which represents an area of winter hardiness for the plants of agriculture and our natural landscape. It also introduces zone 11 to represent areas ... that are ... essentially frost free." Also includes information about the creation of the map, and indicator plant examples for selected woody plants. http://www.usna.usda.gov/Hardzone/ Topics: Agriculture, Maps by Place, Plants, Scientific Themes, U.S. Maps, Weather Last updated Oct 14, 2004 Wieslander Vegetation Type Maps & Photographs
A collection of over 3,000 digitized photographs of natural vegetation in California, taken during the 1920s and 1930s as part of a U.S. National Forest Service survey.
