The Wedge-tailed Eagle Nesting Habitat Model

The WTE Nesting Habitat Model is a high resolution tool that forest planners can use when deciding where to concentrate eagle nest searches. There are three components to the model; the low elevation model (L850), the high elevation model (G700) and the north-west model (NW). There is some overlap between the low and high elevation models and for these areas it is recommended that both are examined.

The different 'gridcode' values in the model indicate the relative likelihood that an eagle nest will be found in a particular area. For example, a gridcode value of '8' indicates a nest is very likely to be found (similar to a probability of presence value of 0.8-0.9), while a gridcode value of '0' indicates a low likelihood of finding a nest (probability <0.1). There is no set level at which nest surveys must be conducted, but the larger the search area the more nests are likely to be located.

For further details on the development, use and limitations of the wedge-tailed eagle nesting habitat model, see Fauna Technical Note No. 6.
