The northern savannas are primed for regular fire with vast grassy landscapes that flourish during the wet season and then, over months with very little rain, dry to a tinderbox. Although not nearly as intense as southern bushfires, the problems these fires are now creating for the people of the north are considerable, whether for managing cattle stations or protecting fire-sensitive plants and animals.
These regular supplies of dry, grassy fuel for fire lead to massive wildfires and the destruction of many ecosystems and animal habitats. Most of all wildfires in Australia are in the northern part, the savanna. Recently, people found the cigarettes are the cause for about 20% of the wildfires in the savanna.
To further prevent wildfires, all you need to do is to not smoke while out in the savanna. For all you know, you could have destroyed an entire ecosystem just by dropping it on the ground. Next time you're out there, please take care of the environment with safety and care.
Poaching is also a major issue right now in the savanna. People are purposely going out and killing innocent animals like the kangaroo to sell for food or money. The animals in the savanna have decreased in the past few years because of poachers killing these animals for their skin and meat.
