Robinia pseudoacacia? Yes, it is semi-naturalised here. But it
doesn't last all that well - our conditions are a LOT tougher
than yours in this respect. Also, the wood is probably rather
softer, because of our miserable summers.

The only wood that I know of that grows in the UK that is seriously
resistant to rot at the soil boundary is yew, and then only the
heartwood. Oak, locust, hawthorn etc. heartwood and yew sapwood
have some resistance, but only a few year's worth at 3" diameter.
