Thanks for the reply.

In addition to mines, barbed wire, etc. there is also an option in some scenarios to use the E key to have all appropriate units create foxholes, etc. in the position they're placed. Pressing the E key again updates these to the current positions of the units, but there doesn't seem to be any way to simply eliminate the entrenchments.

It's not a big deal, since they're not doing any harm though there are some hack possibilities, as entrenchments don't appear to be removed if the unit that made them is loaded onto a transport.

I found a work-around. If you put a unit on a hex in which it can't entrench it's previous entrenchment will be removed but no new one created. You can also put the unit on the grey border hexes and press the E key, which will entrench there, where they won't affect the game.
