1500 km2 of tropical savanna dotted with crystal clear water holes. Camping off the beaten track in Litchfield National Park is pretty special

Older individuals make vital contributions to moderate and long-lived species, migratory animals and this where knowledge and cultural transmission are important. We refer to these as old animal storage effects and synthesise the benefits across life history strategies

Old animals across a wide range of taxa provide important ecological functions, but these are being eroded.
