Depending on which variety (cultivar?) it is, you might find a goat herder who would love to have it for the goats. If it's sericea lespedeza, it contains an amount of tannin that is beneficial as a natural dewormer. However, as I've continued to investigate this, the tannin levels go down the longer the forage is cut and not consumed by the goats. There is a peak time when it should be harvested for highest tannin content. Maybe you can harvest the lespedeza and trade with the goat herder for some meat or
dairy product. It is a bit invasive, so on a huglemound, I can see it could take over. I just planted 1/2 acre of sericea lespedeza between two swales for the very fact to
feed it to goats. But, we'll see how the experiment goes.
