Bird cherry fence posts?

Hej!
Over the winter, I cut a bunch of prunus padus (bird cherry/hackberry) to let some more sun into one of our growing areas, and I was wondering; does anyone out in permieland have any experience with using prunus padus as fence posts? I have about 3 kilometers of fencing that needs to be put up (not all at once, thank the gods) and if I can use the stuff I cut anyway, it'd be good, but I'm *powerfully* uninterested in setting several dozen posts that I'll have to replace in a couple of years, so if it rots quickly in the ground, I'll  use them for heat next winter instead.

Happy spring!

I would not recommend them for fence posts. My experience is that the bark is very resistant to decay but the wood rots very rapidly. I have used them as props with only the end on the ground and come back to discover the bark standing there almost hollow. It is a sturdy wood for applications where it is kept dry and is attractive to look at. It is very dfificult to split because of the bark.

Hej Hans!
 Thanks for your answer. I was kind of afraid it would be something like that. Oh well, I'll just use them for inside applications,then.
