America's 100 biggest landowners increased their private holdings by 500,000 acres in the past year, according to The Land Report, which just released its annual list of landowners by acreage. Media tycoon John Malone, who owns 2.2 million acres — more than twice as much land as the state of Delaware — tops the list for the fourth year running. Privately-owned, The Collins Companies runs timber operations from Pennsylvania to Oregon. Since 2010, they've added around 17,000 acres to their holdings.
