Yes I've just bought a load of pales to hold up a new dead hedge. Sweet Chestnut lasts for donkey's years in the ground but when I built our pergola I dug out the 6-7" post holes with only an inch or two of space around then back filled with rammed gravel, as that is what the supplier advised.One major use in the UK was/is for palings joined by twisted wire - these can take being knocked into the ground and seem to even outlast oak in this situation where so many woods rot fast (stuck outside in British weather, untreated, half in the soil) - just been removing some 30+ year old palings from the middle of a hedge - the galvanised wire has mostly rusted away, but the palings are destined for further use. They are cleft, not sawn, and far from straight, but look great to my eye.
