And as an add on to the previous, Ag. land (fenced with cattle or crop land) is taxed at a lower rate than open undeveloped land adjoining residential or commercial property. Only makes sense to keep the buffalo/cattle until such time as the property is developed.
This is not common to the villages. When I lived in Miami Lakes. FL many moons ago, Senator Graham who owned a considerable amount of acreage did the same. His family, I believe, originally had a dairy prior to the development in the 70's.
