Location Specific Impacts:
Northern Territory (Australia)
Habitat alteration: The yellow-billed Egret (Mesophoyx intermedia) is listed as Least Concern (LC) in the IUCN Red List of Threatened Species. Its habitat in the Northern Territory of Australia is under threat due to burning, grazing and the spread of invasive alien plants Mimosa pigra and Salvinia molesta. Introduced feral buffalo are also a threat causing breakes in the levees leading to salt intrusion and accumulation of salt settlement (BirdLife International 2009).
Reduction in native biodiversity: A study of the diet and breeding success of White-bellied Sea-Eagles (Haliaeetus leucogaster) in Kakadu National Park with (between 1980-85) and without (between 1992-94) high densities of feral water buffalo showed that there was no significant difference in the diet in the years with or without buffalao. However, more "Sea-Eagle pairs attempted to breed (100%) and fledge young (83%) in years without buffalo than in years with buffalo when 63 percent of Sea-Eagle pairs attempted breeding of which 46 percent were successful" (Corbett et al 2012)
