Mapping of Glossy Black-Cockatoo habitat in the Biliirrgan project area (the Nambucca, Bellingen, Coffs and Clarence Local Government Areas in northern NSW). The mapping for Nambucca, Bellingen and Clarence LGAs is derived from the State Vegetation Type Map (SVTM, release C1.1M1) using Plant Community Type data; the mapping for Coffs LGA is derived from the fine-scale mapping of the Coffs Harbour Local Government Area (VIS_ID 4189) using vegetation community data. PCTs/vegetation communities were classified as Glossy Black-Cockatoo habitat if either Allocasuarina torulosa (Forest Oak) or Allocasuarina littoralis (Black She-oak) had a mean cover-abundance score of at least 2 (equating to at least 5 plants, and at least 5% cover, in a 20 m by 20 m plot) AND the frequency (i.e. the proportion of flora survey plots in which a species was recorded) of Forest Oak and Black She-oak in that community summed to at least 10%. Habitat was subdivided into classes (e.g. littoralis_High) based on the frequency and cover abundance of the most frequent Allocasuarina species. Sites from all habitat classes were surveyed in the field, and the density of Allocasuarina cones was estimated, allowing the calculation of the mean number of Allocasuarina cones per hectare for each habitat class.
