Been wondering how zone maps are changing as climate change accelerates.

Instead of the Minnesota DNR tree sale program. I typically plant 100-200 tree seedlings a year for habitat restoration on family land. I started 20 yr ago. I also grow a lot from seed I either collect, buy or trade for on Facebook groups.

I realized a few years ago the climate the trees here in Minnesota evolved for is gone. The trees currently growing here, that the MN DNR keep using for seed, are zombies. They won't cope with the climate of 2050, much less 2100.

Instead of the white pine, black cherry and bur oak the Minnesota forestry dept sells, I'm planting bald cypress, sweet gum, tupelo and chestnut oak from Missouri. I have pawpaws and persimmons from northern Illinois. Chestnuts from Iowa. Pecans from an experimental grove the U of MN planted in the 70's.

And they're all thriving. Our climate is GALLOPING towards a new epoch.

Pine seems like it's not doing well. Been on this property since 1988.

Thanks for the news.

My wife follows the wine industry and in many locations in the last 5+ years, wineries are pre-emptively buying land at higher altitudes understanding their valley locations, even close to the ocean, will no longer sustain cool climate grapes. The valleys will get warmer and the grape varieties will have to switch to match that. And the cool varieties will have to gain altitude to get the right temperature range.

I didn’t know anything about this. This goes to the OP too.

Might plant avocado , lime and olive trees … yum

Isn’t there a similar map for high temperatures?

The place I live in was 7 when I moved here. Then it became 7A, then 7B, now 8.

Everyone who has a garden has known this for many years.

Losing your mind now sounds like they just now became woke.
