Well when you put it that way, I feel silly

Don't put it into the I'll do it later category, you need to do it asap. It is possible it could be dwarf mistletoe and that stuff is a dangerous parasite.
thanks, and now I'll never forget!Fir needles are Flat

Still; you don't want that stuff mucking around on your bark it ruins it.Had no idea about mistletoe.. Horrible stuff.
Glad to say it was moss and muck.
The last tree you have looks like a Abies procera to me, aka noble fir. Nobles are native to my area and identifiable by hockey stick-shaped needles, among other characters. I wasn't aware they were common in landscape plantings, so it may be another for species. I can only identify those native here and the balsam fir, but there are many others around the world.
Nice fat trunks on the alders. Alders are not super common as bonsai, but have been used. I recall seeing a few images of alders at bonsai shows.
They will have large leaves, they should reduce, but won't get as small as an elm for example. They will reduce to a size good for medium and larger size bonsai. In terms of handling the leaf size, look to the Tilia species, the size and reduction will be similar.
They may also have the habit of producing suckers from the roots. Easy to manage, just prune them as they appear. Don't leave them more than a season or two, as they will compete with the older trunk for resources from the roots.
Early spring is a good time for the repot and chop low. So think about what size tree you want, and chop to a height about one third or less of your final vision for tree size.
Cheers Leo, that's the plan
Hi Victorim,
I don’t know whether you want the extra plants from doing any air-layers but if you are planning to trunk-chop the dawn redwood down to 30-40 cm you could air-layer top off first (eg. 2 for the price of 1 etc).
Many will disagree with me here as air-layering just for having more trees to work with is not their idea of “air-layering trees for good trunk section” etc.
As @rockm says, treat as deciduous as they grow wherever you chop them.
My 2 cents worth, especially like the Cedrus libiana?

Dawn Redwood and Alder will most likely respond well to air layering when done in spring or summer. It may take more than 12 months, but it could happen quickly, say 3 months.
Cedrus is not known to air layer, at all. Don't bother trying the technique on them.
In general if a tree can be propagated by cuttings, it can be air layered. If it is known to be difficult or impossible from cuttings, it will not air layer.
