The threat to America's public lands is increasing – and so is our coverage

This Land Is Your Land is our series on an American birthright at risk amid privatization, energy extraction and climate change

• Rotting cabins, closed trails: shining a light on national parks

Public lands are an American birthright like no other. Managed by the government and held in trust for the people, they range from celebrated national parks such as Yosemite, Yellowstone and the Everglades to vast western forests and deserts, Pacific coral reefs and Atlantic seamounts. Yet now their future hangs in the balance.

This is why we are delighted to announce a major expansion of our series This Land is Your Land, which will provide coverage of these unique and threatened places.
