4.3.3 Conservation significant flora Two conservation significant flora species were confirmed present within the project area ( Grevillea hockingsii and Cycas megacarpa ). G. hockingsii is listed as vulnerable under the NC Act (Queensland) but not listed under the EPBC Act (Commonwealth). A population of approximately 67 individuals was confirmed along the northern slopes of Upper Mundic Gully. Individuals ranged from seedlings to mature flowering/seeding individuals. All individuals appeared of good health. In addition to the above population, approximately 29.5 ha of suitable habitat has been mapped for the species within the project area. Suitable habitat for the species, within the project area, has been described as low woodland to open forests dominated by of Corymbia citriodora, Corymbia trachyphloia, Syncarpia glomulifera and/or Acacia spp, on steep slopes and hill crests with shallow, well drained, sandy loam soils derived from sandstone or basalt volcanic rocks. Within the project area this suitable habitat has been verified within both remnant and HVR vegetation. The aforementioned population and its mapped suitable habitat is depicted in Figure 4.2. Representative photos of G. hockingsii , within the project area, are presented in Figure 4.2. This species is further discussed in Section 4.5.2.1. C. megacarpa is listed endangered under both the NC Act and EPBC Act. A population of approximately 105 individuals were confirmed along the southern extent of the project area. Individuals ranged in height from 0.3 – 5.5 m tall, with multiple individuals noted with fruit. Health varied across the population. Some individuals presented healthy foliage and new growth, while others presented signs of chlorosis (yellowing) and/or insect herbivory. Multiple dead trunks believed to be C. megacarpa were noted amongst live individuals. In addition to the above population, approximately 34.17 ha of suitable habit was mapped for the species within the project area. Suitable habitat for the species, within the project area, has been described as both remnant, HVR and non- remnant vegetation on steep slopes and hill crests with shallow, well drained, sandy loam soils derived from sandstone or basalt volcanic rocks. Remnant/HVR suitable habitat is defined as woodland to open forests dominated by of Corymbia citriodora, Corymbia trachyphloia, Syncarpia glomulifera and/or Acacia spp . Non- remnant suitable habitat is defined as young Acacia spp. regrowth with mixed native and exotic grassy ground cover. The aforementioned population and its mapped suitable habitat is depicted in Error! Reference source not found. . Representative photos of C. megacarpa , within the project area, are presented in Plate 4-3. This species is further discussed in Section 4.5.1.1.
