This shows Marwell's original zoogeographic layout when it opened. It was ruled out a few years later due to management problems, though the masterplan created by James Cretney will regroup the zoo's collection into areas based on their range in the wild. This officially started in 2007, with the Australian Bush Walk forming Phase 1 of the Australian Bush biome and Life in the Trees as Phase 1 of the South-East Asian Rainforest biome.
