Should we tell the scientists who did this study that chestnut will NOT survive the climate change toward drought and higher temperatures ?

Given that the American Chestnut once grew across the entire eastern United States, there is much more space for raw numbers to bounce back before climate change comes into play

Chestnut is one of the species listed to be critically endangered by climate change. I have 2 chestnuts in my garden (in Europe), a young one (15years) and an old one (more than 30 years) they both required watering for 3 of the past 5 summers. Who will go and water the new ones planted when it will be 130F ?

It’ll be a while until the eastern us is 130. It’s rare for Death Valley and the Mojave desert (where I live) to hit that.

120 in Lytton, in 2021, remember ? Exceptional until it becomes usual and then 130 will be exceptional and... they will become norms... But by then chestnut will not be the only one struggling.

An european study:

Beech and chestnut have been flagged as the first trees to suffer from climate change. In Europe we started to replace green oak and chestnut killed by drought with cedar and other trees drought resistant.

The efforts and resources to grow a young tree cannot be wasted on the wrong specie knowing it will only become ever more difficult to grow them in the future if they need to be replaced.

Chestnut once covered the whole Eastern Forest range.

The American Chestnut fairs much better than others in America this study doesn't even look into them.

While climate change will push their range north that means they will be able to be grown in Canada along with much of their historical range.

Also they have larger nuts and bigger crops than the Chinese Chestnut. So it's quite exciting for the future.
