The SMH had an interesting piece on the possible demise of the "Long Paddock" - land reserves for stockmen to move livestock around the country on foot. While it is rarely used nowadays, the land reserved for this use has a lot of environmental value - and (for those of a reversalist bent) they could possibly be revived one day if moving stock around by foot becomes the most energy efficient means of transportation to the markets - something the Queensland government seems to believe (it also maintains a website tracking rural climate issues using this name).
