However, the remaining vast tracts of unsettled land were often used as a commons, or, in the American west, "open range." As degradation of habitat developed due to overgrazing and a tragedy of the commons situation arose, common areas began to either be allocated to individual landowners via mechanisms such as the Homestead Act and Desert Land Act and fenced in, or, if kept in public hands, leased to individual users for limited purposes, with fences built to separate tracts of public and private land.
Ownership of the fence varies. In some parts of the country all boundaries are shared; in other parts of the country you may own the boundary on the left-hand or right-hand side, however, only the title deeds can be depended on to tell you which side is yours. (A 'T' symbol indicates who is the owner). It used to be normal for the cladding to be on the non-owners side (enabling access to the posts for the owner when repairs need doing), but increasingly this cannot be depended on.
