Angophora subvelutina (Myrtaceae) on atypical diatreme habitat at Glenbrook : an addition to the eucalypt list for the Greater Blue Mountains World Heritage Area

  • The Greater Blue Mountains World Heritage Area (GBMWHA), a natural area of about one million hectares immediately west of Sydney, Australia, is significant for its biodiversity, and particularly for its richness of eucalypt species (species of Eucalyptus, Angophora and Corymbia in the family Myrtaceae), numbered at 96 species in 2010. This paper describes the finding of a previously unlisted Angophora species in the GBMWHA, and makes a conservation assessment of the population. A population of the Broad-leaved Apple Angophora subvelutina F. Muell. occurs at Euroka Clearing south of Glenbrook just within the eastern edge of Blue Mountains National Park, one of the eight conservation reserves that make up the GBMWHA. The population numbers over 200 plants and there is evidence that the species has been present at the site since before European settlement. The population includes a mixture of age classes and is considered viable, although substantial intergradation is occurring with the closely related species Angophora floribunda. Elsewhere in the Sydney area, the species is relatively uncommon and has been extensively cleared from its relatively fertile habitats. The population in the GBMWHA noted here has conservation significance for its size and long history at the site, and for the unusual ecological conditions of the Euroka diatreme, which is an atypical habitat for the species.
