Forests in the Northern Territory can be considered to belong to the following formations: Acacia shrublands, eucalypt savannah, swamp, mangrove and monsoon forest The wildlife in monsoon forests and surrounding eucalypt savannah are the best known. Wildlife research has been dominated by zoogeography (distribution and habitat preference of animals), particularly in Kakadu National Park. Mammals, and to a far lesser extent reptiles and frogs, have been the focus of autecological studies. Some research has been carried out on the response of insects and vertebrates to disturbance by cyclones, fire and introduced megafauna (e.g., buffalo). No studies have documented the impact of introduced predators (e.g., cats), logging, land clearance or hunting on Northern Territory forest wildlife. Future surveys should focus on Acacia shrublands and swamp forests because these formations are likely to be subjected to increased disturbance through logging and predicted rises in sea level respectively. More knowledge about changing fire regimes on fauna, particularly for species that favour rocky or cypress pine habitats, and the role of animal pollination and dispersal of plants is also required.
