Re: Iceland's Dramatic Landscape

Yah, they did. One fall was extra cold and cloudy and the trees didn't put up enough reserves to winter. They didn't leaf that following spring. It's a bit of a southern species for that location. The American Chestnut Foundation furnished New York seedlots, hoping they might do well, as they were c...

Re: 3 year Chestnut blight survivor

The Canadian Chestnut Council has been backcross breeding for blight resistance, and also gathering up small resistances from local pure species trees. The average resistance of both groups is about the same, with some really resistant trees in both groups. It appears both approaches work. I remembe...

Re: 3 year Chestnut blight survivor

I think I would be planting as many nuts off that tree as I could. There seems to be a slow gathering up of small, horizontal, additive resistance genes. Trees that can produce some nuts in the presence of blight attack may have some some favourable genes. if the nuts from several of those could be ...

Re: Hopes for Chestnut Revival Growing

It's rainy and I'm in the house instead of where I'd like to be, so keep that in mind, grin. It's colder and wetter here than a lot of places, so blight will grow slower, I hope. Those BC1's, hybrid crossed back to americans, will all have chinese traits, but some will not get a copy of all the blig...

Re: Hello, All

Allan, here's a tree for you. It came as a potted seedling from New York somewhere around 1903. It lives in Nova Scotia now.

Re: Maryland's effort to restore hemlock forests

Are they not finding a few resistant individuals? I read somewhere that some trees are resistant and they are rooting cuttings from those ones to establish a clonal seed orchard for local seed.
I can't find the reference right now.
