You can get a firm in to grind the stumps. Otherwise the only thing is to dig out the roots and use weedkiller on the re-growth.
If you don't want to remove the roots, the only alternative is to make raised beds.
Ash seedlings get everywhere so I would advise anybody who finds a seedling ash in their gardens to remove it sooner rather than later.
