Fence the horses out and plant what you want.

Walnut lumber is probably as rot resistant as black locust. I do not
know times to harvest for useful lumber or posts compared to black
locust. Black walnuts are a valuable cash crop (black walnut cake is
traditional and unique in flavor).

Paulownia wood is another high value cash crop. It can be exported to
Japan where is prized for making tool boxes; it is lightweight and
fairly strong. It is such a valued crop that Paulownia poaching is a
problem in some areas.

Eleagnus umbellata is a very important, very high quality food plant.
Though potentially invasive it can be controlled by mowing or manually
with hand tools. It is worth having it in orchards because of its value
as food and medicine (preventive). There have been good discussion
threads on this plant in the nafex and permaculture lists fairly
recently. You can find this in the archives:
