Me from the back of the conference hall hoping they play my favourites: "Do Hazelnut next"

I had suspected as much. Considering how much topsoil was depleted in the Eastern U.S. following the devastation of the American Chestnut blight during the 20th Century, I wonder if massive re-forestation would improve the soil across the range? Though, it would likely take centuries before there is any measurable difference?

The study and report cited in the article show that the effects of soil improvements and soil carbon sequestration can already be measured in as little as five years, so there is hope!

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

I'm not a huge fan of the Chinese chestnut strategy--but hopefully the American chestnut approval comes along soon and we can start sinking carbon with those massive trees again.

Public comment is open at the US Federal Gubmint site. Tell them how much you want chestnuts restored--how good for the environment, etc.

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

Chestnuts were a huge mast ecology. The Passenger pigeon depended on it.

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 ?

The American chestnut is the native species, and as such, has adapted characteristics enabling it to be a competitive forest tree (tall and straight, climate adaptations etc.) that the Chinese tree somewhat lacks. The blight resistant American chestnut tree under development by TACF and SUNY is a transgenic organism. Meaning that a gene from wheat has been inserted (oxalate oxidase.)

We eat this gene in massive quantities every day, but you know how some people are about transgenic technology.

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:
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8309319/

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.

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.

As u/marcusregulus says, it's non-native. I don't know why people want this when every other times people talk about introducing species they say 'cane toad' and 'purple loosestrife' and those god-forsaken water chestnuts that I pulled out of the Mystic River for years.

Why don't they see that here? I ask the same thing every time someone wants Wolbachia instead of GMO mosquitoes and end up just rolling my eyes back in my head. People who claim to be environmentalists somehow can't figure this out.

Anyway: the American chestnut is what should be used.
