The new Landscape South Australia Act 2019 has now been passed by SA Parliament.
Over the next eight months, Natural Resource Management boards across SA will be replaced by eight new regional Landscape boards.
On Kangaroo Island, newly appointed NRM board chairman Andrew "Aphid" Heinrich, a Parndana farmer, will oversee the transition from KI NRM to Landscape Board.
Environment Minister David Speirs said land levies, capped by CPI, would continue to be collected by local councils.
The new regional landscape boards would operate at arm's length from government, delivering "simple, effective and clear priorities, to empower; local communities to sustainably manage their region's natural resources".
There would be an emphasis on water management, pest, plant and animal control, soil and land management, he said.
