Buffalo Skull is owned in fee by Philadelphia Community Farm who, for consideration, has donated conservation and management easements to Standing Cedars and WDNR.

The North and West boundaries are bordered by National Park Service lands as part of the Lower St. Croix National Scenic Riverway.  The National Park Service holds scenic easements on roughly 45 acres of the site along the Western edge.

The dry prairie, approx 22 acres, had been farmed in the distant past, but due to sandy/rocky soils and nearby seed sources, has reverted back into native species with a surprisingly diverse species list that includes besseya bullii- aka Kittentails. Land on the north of 55th Avenue contains some of the most readily identifiable, accessible and manageable oak savanna on the property.

One of the unique features of this site is a naturally occurring spring (Buttermilk creek) which emanates from rock outcroppings in a ravine and forms a .6 mile stream joined by water from other small streams before flowing over a 40 foot fall and eventually entering the St. Croix river. This stream cuts through the NE corner of the property and continues through a 20-acre parcel owned by the NPS.  Buttermilk Falls is on National Park Service land.
