Although I appreciate the work folks like Tom Brown do, the notion that he has actually rescued 1000 varieties is a bit of a stretch. An apple variety is only really rescued when it has found a home in commerce and some significant consumer base wants it. Otherwise it's just on life support in a museum, and maybe in a few home orchardists' little collections of trees - it's perpetuation still hanging by a thread. In particular, trees grafted, as Brown's are, onto dwarf roootstock, sometimes mutiple varieties per tree, and maintained by an 80 year old retiree, could all be gone again in a decade or two, even if his records are meticulous. Dwarf apple trees don't live long, and a single ice storm or hurricane could kill hundreds of varieties in a single pass.
This is not to dis Tom's work, only to say, the actual rescue is very tenuous.
