By 1997, 81% of the lowland native vegetation, the Cassowary's essential habitat, had been cleared, with the rest of the rainforest habitat in the Wet Tropics highly fragmented. In the past decade, clearing rates have slowed from 3,000 hectares to 1,000 hectares a year, but this is relatively constant. (Latch 2007)
Ongoing habitat destruction is driving the reduction of the number of Cassowaries left in the wild. As the clearing and fragmentation of rainforest for residential development continues, the Cassowary is driven closer to extinction day by day.
The rainforest of the Wet Tropics is subject to cyclones, which a healthy, intact rainforest can recover from relatively quickly. However, rainforests that have been fragmented take a longer time to recover, leaving the Cassowaries prone to starving and suffering exposed to the hot sun and for longer periods of time.
