A statement for the purposes of approved conservation advice (s266B of the Environment Protection and Biodiversity Conservation Act 1999) Approved Conservation Advice for Grevillea calliantha (Foote’s Grevillea)
This Conservation Advice has been developed based on the best available information at the time this conservation advice was approved. Description Grevillea calliantha, Family Proteaceae, commonly known as Foote's Grevillea, Cataby Grevillea or Black Magic Grevillea, is a spreading, flat-topped shrub growing up to 1 m, with a conifer-like appearance. The flowers are greenish-yellow on the outside, ageing to apricot- orange, with a maroon to blackish or reddish style. Conservation Status Foote’s Grevillea is listed as endangered. This species is eligible for listing as endangered under the Environment Protection and Biodiversity Conservation Act 1999 (Cwlth) (EPBC Act) as, prior to the commencement of the EPBC Act, it was listed as endangered under Schedule 1 of the Endangered Species Protection Act 1992 (Cwlth). Foote's Grevillea is also listed as rare flora under the Wildlife Conservation Act 1950 (Western Australia) and on the Wildlife Conservation (Rare Flora) Notice 2006(2) (Western Australia). Distribution and Habitat Foote’s Grevillea is endemic to the Dandaragan area of south-western Western Australia, where it occurs over a range of 8 km (Brown et al., 1998) within the Northern Agricultural Natural Resource Management Region. There are six known populations (CALM, 2001). It grows in grey or yellow sand or sandy clay on lower to mid level slopes to low hills and rises, or sometimes on slopes in shallow gullies between lateritic ridges. Foote’s Grevillea grows in low heath and dwarf scrub under open low woodland of Eucalyptus todtiana and E. calophylla with associated species including Calothamnus quadrifidus, Hakea trifurcata, H. prostrata, Allocasuarina humilis and Gastrolobium spinosum (Olde & Marriott, 1995; Brown et al., 1998; Patrick & Brown, 2001). Foote’s Grevillea is cultivated throughout Australia through the commercial nursery industry and is grown within the Royal Park and Botanic Gardens, Western Australia. The Northern Agricultural (Western Australia) Natural Resource Management Region promotes the cultivation of this species by community and farming groups. The distribution of this species is not known to overlap with any EPBC Act-listed threatened ecological communities. Threats The main identified threats to Foote's Grevillea include clearing of habitat; weeds; accidental damage during road maintenance; herbicide overspray; frequent fire; grazing animals; and dieback caused by Phytophthora cinnamomi (Brown et al., 1998; CALM, 2001). Its susceptibility to Phytophthora cinnamomi is unknown, though Proteaceae, in general, are highly susceptible. Research priorities Research priorities that would inform future regional and local priority actions include: • Design and implement a monitoring program. • Determine Foote's Grevillea’s susceptibility to dieback caused by Phytophthora cinnamomi.

Regional Priority Actions The following regional priority recovery and threat abatement actions can be done to support the recovery of Foote's Grevillea. Habitat Loss, Disturbance and Modification • Monitor known populations to identify key threats. • Monitor the progress of recovery, including the effectiveness of management actions and the need to adapt them if necessary. • Identify populations of high conservation priority. • Manage threats to areas of vegetation that contain populations/occurrences/remnants of Foote’s Grevillea. • Ensure chemicals or other mechanisms used to eradicate weeds do not have a significant adverse impact on Foote’s Grevillea. • Ensure road widening and maintenance activities (or other infrastructure or development activities as appropriate) in areas where the species occurs do not adversely impact on known populations. • Investigate formal conservation arrangements such as the use of covenants, conservation agreements or inclusion in reserve tenure. Invasive Weeds • Develop and implement a management plan for the control of threatening weeds in the local region. Browsing or Grazing • Develop and implement or nominate an existing stock management plan for roadside verges and travelling stock routes. Fire • Develop and implement a suitable fire management strategy for Foote's Grevillea. • Provide maps of known occurrences to local and state rural fire services and seek inclusion of mitigative measures in bush fire risk management plans, risk register and/or operation maps. Diseases, Fungi and Parasites • Develop and implement suitable hygiene protocols to protect against outbreaks of dieback caused by Phytophthora cinnamomi. Conservation Information • Raise awareness of Foote's Grevillea within the local community. Enable Recovery of Additional Sites and/or Populations • Undertake appropriate seed collection and storage. • Undertake seed germination and/or vegetative propagation trials to determine the requirements for successful establishment. • Investigate options for linking, enhancing or establishing additional populations. Local Priority Actions The following local priority recovery and threat abatement actions can be done to support the recovery of Foote's Grevillea. Habitat Loss, Disturbance and Modification • Control access routes to suitably constrain public access to known sites on public land. • Suitably control and manage access on private land. • Undertake survey work in suitable habitat and potential habitat to locate any additional populations/occurrences/remnants.

• Minimise adverse impacts from land use at known sites. • Ensure chemicals or other mechanisms used to eradicate weeds do not have a significant adverse impact on Foote’s Grevillea. • Protect populations of the listed species through the development of conservation agreements and/or covenants Invasive Weeds • Identify and remove weeds in the local area, which could become a threat to the Foote's Grevillea, using appropriate methods. • Manage sites to prevent introduction of invasive weeds, which could become a threat to Foote’s Grevillea, using appropriate methods. Trampling, Browsing or Grazing • Manage known sites on private property to ensure appropriate grazing regimes are conducted outside the growing season, i.e. when plants are not fertile. • Prevent grazing pressure at known sites on leased crown land through exclusion fencing or other barriers. Diseases, Fungi and Parasites • Implement suitable hygiene protocols to protect further outbreaks of dieback caused by Phytophthora cinnamomi.
This list does not necessarily encompass all actions that may be of benefit to Foote's Grevillea, but highlights those that are considered to be of highest priority at the time of preparing the conservation advice.
Existing Plans/Management Prescriptions that are Relevant to the Species • Declared rare and poorly known flora in the Moora District (Patrick & Brown, 2001).
