Geographic Range

Range Description:
|
Stagonopleura guttata is found in eastern Australia, from Eyre Peninsula, South Australia, to south-eastern Queensland, mostly on the slopes of the Great Dividing Range. Overall, there has been a decline in density throughout the range, and many remaining populations may now be isolated. Much habitat has been cleared with remaining fragments gradually becoming unsuitable as a result of competition with invasive species, predation of adults or young, alteration of vegetation structure through over-grazing, weed invasion, salinisation and other flow-on processes. The severity of most degradation is correlated with the area of the fragment. Factors that have been postulated to be adversely affecting this species in particular include the loss of key food plants and habitat as a result of invasion by exotic grasses more suitable for flock-foraging Red-browed Finch Neochmia temporalis, whose expansion in some areas may have disadvantaged S. guttata. In the north of the range, a change in fire and grazing regimes may have played an important part in the decline. The species may number c.200,000 individuals and is continuing to decline, particularly in the more intensively developed parts of its range.
