located on the Conondale Ranges west of the Mary River at approximately 600 m ASL (Powell unpublished data). A finger of populations extends northward along coastal foothills to Goomboorian, a distance of approximately 50 km. Macadamia ternifolia is also found in the Sunshine Coast suburb of Buderim and the Brisbane suburbs of Samford Valley and Mt Nebo. Typically, populations are small and tend to occur in clusters within the forest matrix or along riparian zones.
The occupied habitat is approximately 1,350 ha and the modelled extent of available habitat is approximately 22,000 ha within an area of 3,100 km2. The total population is found within approximately 60 key locations with 5–25 mature specimens at each. Significant population clusters occur in the north from Goomboorian to Cooroy; the centre of the species range in the Blackall Range, Maleny and Buderim; in the Conondale Ranges and west of Kenilworth; and Samford Valley/ Mt Nebo in the south. Further surveys will improve knowledge of population size and distribution.

Habitat critical to the survival of the species
Macadamia ternifolia is found in several rainforest regional ecosystems including complex and simple notophyll vine forest and simple microphyll-notophyll vine forest with emergent Araucaria and Argyrodendron. Macadamia ternifolia is identified in the Queensland Herbarium REDD as occurring in endangered RE 12.3.1 (see Table 7), though it is also frequently found in RE 12.8.3, 12.11.10, 12.12.1 and 12.12.16 (Powell unpublished data).

Priority populations
Prioritisation of populations has been assessed using the same criteria as those used for M. integrifolia. The site identifier (Site Id: MGA northing), location, tenure, habitat, population size (Pop Size), and the priority (very high, high or medium) of known population clusters of M. ternifolia throughout its distribution is summarised in Table 7.
