[edit] Merging other hardiness zone articles

All 3 articles are stubs and overlap. Let's consolidate the info into a meaningful article. -- P199 13:52, 5 May 2006 (UTC)

Support - Merging 3 stubs into 1 actual article sounds like a good plan :) I'm hoping to add some content and several links, but I don't want to start until after they merge (If they merge). Doc Tropics 03:13, 17 June 2006 (UTC)

Support - I could imagine the article being cleaner after merging. Hey, Doc Tropics, I hope you (or someone else) will edit to note that The Arbor Day Foundation has again updated their map. "2006 arborday.org Hardiness Zone Map" Due to the implications in the climate change debate, the mid-December 2006 release gained coverage in the Washington Post, the New York Times, among other newspapers. Also, because this is clear, undeniable evidence of climate change, I believe it begs the question, why hasn't our federal government revised the map since 1990?

Hi, just thought I ought to introduce the "Cold Hardiness Zone Map of the British Isles" It's been around for many years now, but you evidently haven't seen it. The map you have for the UK is basic and only shows the 4 zones. It's sort of correct, but the British Isles is far more complex than that, which the "Cold Hardiness Zone Map of the British Isles" has done a lot to rectify. You may contact the administrator of the site for a flat image if you so wish.

[edit] US and UK hardiness zones compared

Despite the warming effect of the North Atlantic Drift on the British Isles, somehow the Shetland Islands and truly subtropical southern Alabama having the same hardiness zone did not seem right to me. Looking at the USDA hardiness zone map for southern Alabama, it shows it as mostly 8a (10-15° F average minimum), with the Mobile Bay area as 8b (15-20° F average minimum.) The US system is defined with Fahrenheit ranges and the UK system with Celsius ranges. Compare this to the Shetlands on the 8-9 boundary of the UK system, or approximately -7° C average minimum (19.4° F.) While the annual minimum temperature in the Shetlands is similar to Mobile Bay, the average winter temperature of the latter is greater due to greater daily ranges and higher daytime winter temperatures.

[edit] US Hardiness Zones

The USDA updated the US Hardiness Zone map in 2003, it led to significant reclassifications in the the Deep South, including moving Atlanta, Charlotte, Birmingham and Memphis from Zone 7 to Zone 8. I cannot find a 2003 map that is from a source eligible to be uploaded to wikipedia. I have also searched for an Australian, NZ and South Africa hardiness zones map and found a few, but whereas the maps were from the respective Australian, NZ or South African government, I could not update them to Wikipedia in the same manner that the US Government publications are open source and eligible for publication here. Any Ideas? —Preceding unsigned comment added by 24.126.132.88 (talk) 12:07, August 24, 2007 (UTC)
