Bertya granitica is a branched shrub growing to 1 metre high (Halford & Henderson 2002).

This species is restricted to a small area near Mundubbera, in the Burnett district of south-eastern Queensland (BRI undated; Halford & Henderson 2002; Leverington et al. 2003). It is known only from three populations containing a total of 40 individuals (Leverington et al. 2003). The species has a range of approximately 8 km and occurs on leasehold land used for cattle production (D. Halford 2001, pers. comm.).

Bertya sp. Beeron Holding (P.I.Forster 5753) was formally described as Bertya granitica in 2002 (Halford & Henderson 2002).

It is most closely related to Bertya pinifolia but differs in its shorter and proportionally broader leaves, its generally larger female calyx lobes, its larger capsules and its larger seeds. B. granitica is also similar to Bertya recurvata and Bertya gummifera but differs in leaf shape and the appearance of the calyx lobes (Halford & Henderson 2002).

This species grows in shallow, sandy soils on exposed granite outcrops (BRI undated; Halford & Henderson 2002). Soils are weakly acidic and dark in colour due to high organic content. The climate is subtropical and subcoastal, with hot, moist summers and mild, dry winters (Leverington et al. 2003).

Surrounding vegetation is predominantly open forest or open woodland with an open to sparse shrub layer. In the upper stratum, co-dominant species include Eucalyptus exserta, Eucalyptus petalophylla and Eucalyptus dura, with Acacia grandifolia, Allocasuarina inophloia and Callitris endlicheri occurring occasionally. The understorey is diverse in composition and structure. Much of the area is dominated by Triodia pungens. Other frequent species are Leptospermum polygalifolium, Xanthorrhoea johnsonii, Acacia eremophiloides, Cleistochloa rigida, Pomax umbellata and an unidentified species of Aristida. A number of rare and undescribed plant species occur in the area (Leverington et al. 2003).

Weed invasion and soil degradation are minimal. The habitat of the area is considered to be in relatively undisturbed condition and the property has been considered for inclusion in the National Park estate (Leverington et al. 2003).

Flowers have been recorded from August to September, with fruits appearing from October (BRI undated; Halford & Henderson 2002). Plants are monoecious (having male and female flowers on the same plant) or rarely dioecious (having male and female flowers on different plants) (Halford & Henderson 2002).

The species has low genetic diversity and its genetic profile suggests that it has been geographically isolated from near relatives and has developed in isolation, possibly during the Quaternary period. Very little is known about the ecology of Bertya granitica (Leverington et al. 2003).

There appears to be a close relationship between seedling recruitment and fire (Leverington et al. 2003).

The following table lists known and perceived threats to this species. Threats are based on the International Union for Conservation of Nature and Natural Resources (IUCN) threat classification version 1.1.
