Garnaud (ed.). background: #ddd; Ranking tables for population of Metropolitan Statistical Areas, Micropolitan Statistical Areas, Combined Statistical Areas, New England City and Town Areas, and Combined New England City and Town Areas: 1990 and 2000. Levitt, J. 2012 Development of a new USDA plant hardiness zone map for the United States J. Appl. To read each map, click on the picture or header to see the full-size map. State Maps of USDA Plant Hardiness Zones - The Spruce 5D) and with standard deviations equivalent to or lower than those of the Yakima Valley to the south and considerably lower than those found in the Walla Walla Valley (Fig. Plant hardiness zone designations represent the average annual extreme minimum temperatures at a given location during a particular time period. Widrlechner, M.P., Hasselkus, E.R., Herman, D.E., Iles, J.K., Pair, J.C., Paparozzi, E.T., Schutzki, R.E. Generally, nurseries don't bother labeling plants with "a" or "b.". USDA Zones 4a through 9a are represented in Washington. Publ. White Oak Group, Chicago Heights, IL. Because this decreases the frequency of zone-6a temperatures to 1 year in 6 to 8 years (Table 4), these sites can be considered less risky for grape production. (Map with manual). U.S. Government Printing Office, Washington, DC. ensure high-quality, safe food and other agricultural products; assess the nutritional needs of Americans; sustain a competitive agricultural economy; enhance the natural resource base and the environment; and. Nat. Scientists use the plant hardiness zones as a data layer in many research models such as modeling the spread of exotic weeds and insects. See Table 1 for temperature ranges of zones (1 km = 0.6214 mile). Locked padlock 1990 Mapping it out Amer. 30 C (86 F) or higher. The latitudinal delineation of zones in the central part of the conterminous United States is readily apparent, ranging from zone 3a in extreme northern Minnesota to zone 10a in extreme southeastern Texas (Fig. Static images of national, regional and state maps also have been included to ensure the map is readily accessible to those who lack broadband Internet access. Climate of South Dakota, p. 688703. USDA Zones 5a through 8a are represented in Virginia. Amer. Revised 1981. The development and public release of the updated PHZM will advance our understanding of landscape-plant adaptation and plant distribution through its presentation of accurate minimum-temperature data at a fine scale via a user-friendly interface readily accessible to researcher and gardener alike. Geographical Soc., New York. padding: 0; (2002), Schrader and Graves (2003), Szalay et al. Sketch Publications, Vashon, WA. 6B). The wine project. According to the new PHZM, low winter temperatures here would be expected to be less limiting than in many of Washington's established wine-grape-growing regions. The USDA Hardiness Zone Map divides the whole of the United States into 11 hardiness zones. Climatologically aided interpolation [CAI (Daly, 2006; Willmott and Robeson, 1995)] was used to interpolate the PHZM. Most plants that you buy are marked with a hardiness zone number. Winter injury can limit long-term plant survival and vigor and can reduce production of valuable horticultural products, including flowers, foliage, fruit, and seeds. Plant cold hardiness: From the laboratory to the field. USDA Zones 7b through 9a are represented in Mississippi. Wild lowbush blueberries (Vaccinium angustifolium) are hardy from U.S. Department of Agriculture plant hardiness zones 3 through 7 and plants demand between 1,000 and 1,200 chilling hours -- time below 45 degrees Fahrenheit -- for annual bloom and berry production. The new PHZM is based on extreme minimum-temperature data logged annually from 1976 to 2005 at 7983 weather stations in the United States, Puerto Rico, and adjacent regions in Canada and Mexico. The risk-assessment ability of the updated PHZM is further enhanced when used in conjunction with maps of the 30-year standard deviation in the PH statistic (Fig.
