Biodiversity and Grazing in the Tropical Savannas
Tropical Savannas Australia ’ s Tropical Savannas stretch across Queensland , Northern Territory and Western Australia from approximately Bowen to Broome . Characterised by seasonally dry , grassy woodlands and open grasslands , they cover approximately one quarter of mainland Australia ’ s land area . With a long evolutionary history , the tropical savannas are highly complex and diverse ecosystems , rich in habitats and species of plants and animals . They represent an important refuge for biodiversity , nationally and internationally .
Why biodiversity is important . The true benefit of biodiversity to your grazing lands is not always obvious , and generally underestimated . The expensive and undesirable consequences of unhealthy systems are better known . The real cost of lost biodiversity is evident in other regions ( e . g . salinity in the Murray Darling , desertification in the New England Tablelands ). Land managers in the Tropical Savanna Rangelands have the fortunate opportunity to learn from the experiences of other regions and place proper value on biodiversity .
Some graziers might say ‘ I am farming cattle not biodiversity ’ or ‘ biodiversity doesn ’ t put food on my table ’. However , increasing evidence shows that biodiversity certainly does keep food on the table . The secret is the strong link between country that has healthy , vibrant , native wildlife , and the ability of that country to provide basic , essential services like capture of solar energy , water cycling and nutrient cycling . Central to having resources like pastures , water and nutrient rich soils are the local , native plants and animals .
