Talk:USDA plant hardiness zone


 * Regarding the status of the American Horticultural Society's 2003 map, which is prominently labeled "DRAFT", I contacted the American Horticultural Society directly, and was told by David Ellis (who wrote the linked article about the new zone map) that the AHS draft map has been scrapped and the USDA is working on a new version using more years' worth of data, as the draft version was criticized for being based on only 14 years' worth of data. The AHS and USDA websites still present the 1990 map as the current one. In the meantime he referred me to a separately produced map by the Arbor Day Foundation that is based on 20 years' worth of data. The only version of that map I could find on their website is at http://www.arborday.org/treeinfo/zonelookup.cfm MrDarwin 15:52, 7 April 2006 (UTC)
