Restoration Research of the American Chestnut (Part 2: Science in Action)
HTML-код
- Опубликовано: 6 сен 2024
- The USDA Forest Service, The University of Tennessee, and other partners showcase their research on the American chestnut (Castanea dentata), a species that was extirpated by a non-native pathogen (Cryphonectria parasitica) that causes chestnut blight disease. Over 4,000 hybrid chestnuts that were bred for blight-resistance were planted on three national forests since 2009, and research is still ongoing.
What a wonderful mission......restoring the American chestnut....Thanks
I remember seeing huge, dying Chestnut trees near my home in western North Carolina, as a kid growing up. They're amazing. Mostly they didn't survive the blight & mostly the Chinqua Pen bushes did. Seems there are 2 approaches being used to reinstate this magnificent giant, this one and the genetic modification one. I hope they are all successful.
I’m currently attending the school with the professor that discovered the gene that makes the trees resistant to blight. It was found in a form of wheat plant!
so then no cross breeding with the Chinese Chestnut is necessary, correct? They can genetically modify the American Chestnut. Which would mean all these American x Chinese crosses are more of a detriment than a benefit to the future of the American Chestnut? If not... what does that professor say about how to create blight resistant Chestnuts?

This will help.
@@BornIn1500 depends how you look at it, your either breeding or doing transgenics. Both have their issues. Do some reading it’s pretty interesting
i thank god for trees and my interest in trees. it has been a hobby interest while i worked elsewhere. my brigg meyers interest has said in a toby keith fashion i should have been a forest ranger. it was the same result over 5 takings of the test over 40 years i guess. i can not figure that out or maybe i ought to pursue in my next 60 years. i own a wood lot that was cut down in 1940's and some monster stumps were pulled up and left in a pile that might still be there in a very wet area. in the 1980s i cut a dead tree along the stone wall and found someone with a circle saw mill to cu up my first log into board.
i guess i am a history buff with a forestry woodworking kinda guy. no retirement for me. i owe i owe its off to works i go. god gave me tree knowledge that i should apply before god calls me away from earth or i loose my marbles or my mind.
have a good day and let's work toward a better tomorrow.
@@negativefishermen9286 Inserting a single gene seems much more preferable than crossbreeding and leaving behind hundreds or thousands of genes that shouldn't be there.
Most people have no idea of what we're now missing as the American chestnut has left living memory. It was a staple food crop for countless species, including our own. Thank you for what you're doing. We will not reap the rewards, but our children and theirs will at least thank you for this.
It also provided a much-needed honey flow for bees-- and for the beekeepers!
I am 78 years old and can remember going to a family friends farm in Hudson NH from our house in Somerville, Ma.. Out in frond of the farm house was a very big and beautiful chestnut tree. We would bring home a bag of chestnuts for roasting. One year we went up and the tree was gone. I look back at those days with fondness. If only we could plant another chestnut tree in it's place.
That’s so sad. Such a great story you have. I hope you can find one of those 96% f3 whatever they’re called genetically modified blight resistant trees and go back to nh and plant one. How cool would that be’
What gets me is the complete lack of capability to be educated in this country. There was a root rot fungus introduced in the mid 1800's and no one LEARNED ANYTHING. Like hey maybe we shouldn't let in species that might complete exterminate another species. I thank you and congradulate you (The U.S forestry service) for your service and determination to fix this huge problem. I wonder if there is a tree planting campaign going on.
Happy to see the restoration success thus far.
On a mill trip to Canton NC I attended a presentation of the great American Chestnut and it's unfortunate demise. It was believed then that importing the Chinese Chestnut brought the blight that was responsible. As per this presentation, many attempts have been, and are being made to eliminate the blight and restore that magnificent tree. Hope they succeed.
It seems that this effort will take 300 to 400 years before the American Chestnut reforestation can be considered fully restored.
A fantastic program ! Keep up the good work.
Trying to plant some in northern Idaho! It would be cool to get an orchard up here on my property!
Well that was a shame to lose those big old trees. I've starting growing my own Chestnut trees here in Central Ontario and hope to introduce these trees back into our landscape in a couple years. Also I might add I've been watching this channel for a little while now and you have some good videos in your library except for one that I ran across yesterday, it was about stream restoration which is something I'm doing now and have been for 3 years on a creek that runs through my property, so all information is great to see. Anyways the comments were turned off on that one, unlike all the other vids you have. I think you know which one I'm talking about...it was more about the woman excavator operator than the stream.
Why not plant to reforest strip mines?
Suzanne Simard has some interesting observations of trees in general. I thought it was interesting that trees don’t compete for the canopy as I was always but, rather they share nutrients and parent the other trees.
My father told me about this blight. In upstate Pa. one can find young American Chestnuts, but they do die off rather young. When I was a kid there was a small section a few miles from us where we could actually pick the chestnuts. That patch is gone too.
I would love to see the chestnut back in our forests again. What a great natural resource not just for us, but for the wildlife that relied on it for so long.
@ 5:58 I have had several young Chestnut trees attacked by Japanese beetles.
Luckily they are poor flyers and those traps work good. I hesitate to spray the leaves.
Great work! I remember making necklaces out of chestnuts as a kid - wore em at holloween as a “friar” - like friar tuck - cool to see the hairy pod covering again. Don’t give up!
Are you sure they were Chestnuts or Horse-chestnuts? If the flowers were showy and white, they were Horse-Chestnuts if the flowers were yellow, fuzzy, and fragrant it was a Chestnut 🌰
Can the Pure American be grown outside the Historic Range with no damage from the fungus and root rot?
I think it can. I remember hearing the settlers heading west were taking chestnuts with them when they were settling in Wisconsin and even around the Pacific Northwest.
You all should try planning in northeast Ga maybe in hiawassee Ga when I was a kid they had a lot of chestnut trees
So interesting, thank you for sharing this with us !
Would like to see chestnuts planted on Flight 93 Memorial Grounds in Pennsylvania.
Super interesting!
Good luck everyone, all the best.
I had a thought and wonder if it is happening or about to happen. When i lived in Sullivan County , New York, in Bethel, New York, I had a blighted chestnut tree that was still putting up trunks from the roots. Do you think it would be possible to graft that chestnut onto Chinese rootstock which might allow it to get large enough to flower. If it were possible, just one example of that tree would give you the genetics from the Catskill Mountains with its catkins and burrs that could be added to the gene pool of the chestnut. This could be added to a New York gene base as this tree's ancestors grew in the Catskills since the beginning of time. I suspect that that tree is not alone in that forest. Furthermore, it is 110 miles from the point of origin of the blight, and yet since 1904, has survived, even if only in a functionally extinct state. I lived at 246 Pucky Huddle Road in Bethel, New York, and you will find the tree about 50 yards from the house, near the road. My other question is whether there is any plan to keep a population of chestnuts across the Rockies in Northern California or north? My thought is yes, we conquered this blight, but it's probably not the last. I know that Oregon has Castanea dentata that was brought to it on the Oregon trail. I wonder what people's thoughts might be?
Sell the American Chestnut as an ornamental tree and they will be found all over America
Our game need’s these. Twra
Can you plant some of them in southern eastern Ohio please
So how can one get a blight resistant seedling to plant here in Nashville,Tn?
So if you want backcrossed hybrid trees you can join a local chapter of ACF and do a “seed membership” which is expensive and requires you to sign their germ plasm agreement (basically they don’t want you to turn around and sell or hand out seeds and they will reserve the right to access the trees for scientific purposes). Otherwise you’ll have to wait for the GM trees to be approved.
How can I get some seeds?
Nice job!
Outstanding.
Great work
I’m not an expert and only have limited knowledge, but what are they thoughts when it comes to gene editing technology? Where the original American chestnut’s genes are engineered specifically to resist or inhibit blight and the other disease? Then reintroducing those trees back into the wild. My thinking is if you can specifically engineer for the blight and preserve all the other characteristics of the original tree you wouldn’t have to have the 6% off Chinese chestnut genetic material.
I believe a university in New York has done that using a wheat gene. They’re waiting for multiple government agencies to approve it to be released to the wild. I believe the tree is called Darling 58 or something similar. Fascinating stuff. There are RUclips videos about if.
WEll, good job, at least some people are doing something, most only talking about "Amazonian" forests, where 70% of its native forest are still living.
Is it possible to use CRISPR to transfer just the immunity from the Chinese to the American chestnut ? I know that at UCAL SanDiego is doing that for human disease...
What are your thoughts regarding the Transgenic American Chestnut Developed at SUNY (Dr. Powell)?
How can I help as a middle Tennessean with a couple acres. Would love to help somehow
There is a tree in my yard. It's a young tree. The flies love flowers on the chestnut tree. I don't know which species it i
now...can i get one for my yard?
its like a dream come true!
I realize that the last thing the researchers want to deal with is another quality factor, but the American Chestnut was a great honey producer of a fine quality honey. On the other hand, the honey from Chinese chestnut is reputed to be rank, and that even the bees dislike it.
@@adriaan2618
Maybe they could analyze Chinese Chestnut nectar for what makes it taste bad, and see to it that the new American Chestnut doesn't have that chemical(s).
BTW, why can't European chestnuts be planted in the U.S.?
@@adriaan2618
Better than Chinese Chestnuts.
@@adriaan2618
I assume then that somehow Europe has been spared exposure to the chestnut blight?
7:38 ... 20% is AZUM for 100% AChest !!! The question is will they NUT
...not sold on 94%.
6 coins in th bag are pennies...
ONLY dif'rent coin
ONLY dif'rent tree
ONLY "15/16"
Th almost-American Chestnut
Castanea approximo covidus.
They say trees communicate "danger"
to other trees : what are those saplins tellin th Striped Maples?!
Very seldom do you hear Chinquapins [th shrub] mentioned in these Chestnut "habitat/restoration" areas...probly best.
good luck.
My question is; is there going to be a monopoly on the new gene edited trees. Or is it going to be like the invention of the seatbelt. Is this gene line editing or is it regular gmos where you have to buy it every time like corn or something. If so, how could it be reintroduced to the wild? The back crossing would probably be the better scenario if so
Also not a scientist hahaha
We have 425 acres. 100 acres recenty logged. You are welcome to plant trees here and use as a test site. Please contact me if you need a place. We are in eastern Tn near Cumberland Gap NP
