Interim Recovery Plan for Grevillea dryandroides subsp. dryandroides
Interim Recovery Plans (IRPs) are developed within the framework laid down in Department of Conservation and Land
Management (CALM) Policy Statements Nos. 44 and 50. Note: the Department of CALM formally became the
Department of Environment and Conservation (DEC) in July 2006. DEC will continue to adhere to these Policy Statements
until they are revised and reissued.
Plans outline the recovery actions that are required to urgently address those threatening processes most affecting the
DEC is committed to ensuring that Threatened taxa are conserved through the preparation and implementation of Recovery
Endangered taxa, within one year of endorsement of that rank by the Minister.
This plan, which results from a review of, and replaces, IRP No. 64 Grevillea dryandroides subsp. dryandroides
or replaced. It is intended that, if the taxon is still ranked as Critically Endangered in WA, this plan will be reviewed after
five years and the need for further recovery actions assessed.
This plan was given regional approval on 02 November 2012 and was approved by the Director of Nature Conservation on
DEC, as well as the need to address other priorities.
Information in this plan was accurate at November 2012.

Current status: Grevillea dryandroides subsp. dryandroides is declared as rare flora (DRF) under the Western Australian
Conservation of Nature (IUCN 2001) criteria B1ab(iii,v)+B2ab(iii,v); C2a(i) due to the extent of occurrence being less than
; severely fragmented populations; continuing decline in area, extent and/or quality of habitat and number of mature
; and no subpopulation estimated to contain more than 50 mature
recruitment, inappropriate fire regimes, recreational activities, clearing, grazing, low genetic diversity, competition and
future mining operations.
Description: Grevillea dryandroides subsp. dryandroides is a root suckering shrub to 50cm tall. It usually forms colonies
of less than five plants or is scattered singly amongst associated vegetation. The leaves are dull, yellow-green, each with
leaf lobes 5 to 15mm long. The inflorescence is 3 to 4cm long, and pedicles are 1 to 1.5mm long. Individual flowers are
pink to orange-pink with a grey-green limb. The style is red or pink with a green tip. The perianth is 6 to 7mm long and the
pistil 17 to 18mm long (Olde and Marriott 1993). Flowers occur from September to March (Brown et al. 1998).
Habitat requirements: Grevillea dryandroides subsp. dryandroides is endemic to WA where it is confined to the Ballidu
area. It is found in open heath on grey sandy loam and yellow gravelly sand, with shrubs of Allocasuarina and Melaleuca.
Habitat critical to the survival of the species, and important populations: Grevillea dryandroides subsp. dryandroides
is ranked in WA as CR, and as such it is considered that all known habitat for wild populations is habitat critical to its
survival, and that all wild populations are important populations. Habitat critical to the survival of G. dryandroides subsp.
dryandroides includes the area of occupancy of populations, areas of similar habitat surrounding and linking populations,
additional occurrences of similar habitat that may contain undiscovered populations of the subspecies or be suitable for
future translocations, and the local catchment for the surface and/or groundwater that maintains the habitat of the
Benefits to other species or ecological communities: Recovery actions implemented to improve the quality or security of
the habitat of Grevillea dryandroides subsp. dryandroides will also improve the status of associated native vegetation
including eight priority flora taxa.
International obligations: This plan is fully consistent with the aims and recommendations of the Convention on
Biological Diversity, ratified by Australia in June 1993, and will assist in implementing Australia’s responsibilities under
that Convention. The subspecies is not listed under Appendix II in the United Nations Environment Program World
Conservation Monitoring Centre (UNEP-WCMC) Convention on International Trade in Endangered Species (CITES), and
this plan does not affect Australia’s obligations under any other international agreements.
Indigenous consultation: A search of the Department of Indigenous Affairs Aboriginal Heritage Sites Register revealed
no sites of Aboriginal significance adjacent to populations of Grevillea dryandroides subsp. dryandroides. However, input
and involvement has been sought through the South West Aboriginal Land and Sea Council (SWALSC) and Department of
Indigenous Affairs to determine if there are any issues or interests with respect to management for this species at these
sites.. Indigenous opportunity for future involvement in the implementation of the recovery plan is included as an action in
the plan. Indigenous involvement in management of the land is also provided for under the joint management arrangements
in the Conservation and Land Management Act 1984.
Social and economic impacts: The implementation of this recovery plan may result in some social and economic impact.
Brookfield Rail, it may be through the cost of recovery actions and impacts on land management practices. A mineral
exploration lease also covers the area containing all populations and there is potential for economic impact should mining
operations go ahead.
Affected interests: The implementation of this plan has some implications for land managers, such as Main Roads WA,
Brookfield Rail and the Shire of Wongan-Ballidu, particularly where populations occur on lands not specifically managed
for conservation. Mining tenement holders Yilgarn Iron Pty Ltd may also be affected by actions referred to in this plan.
Evaluation of the plan’s performance: DEC, with assistance from the Central Wheatbelt District Threatened Flora and
Communities Recovery Team (CWDTFCRT), will evaluate the performance of this plan. In addition to annual reporting on
progress and evaluation against the criteria for success and failure, the plan will be reviewed following five years of
Existing recovery actions: The following recovery actions have been or are currently being implemented:
in 1991. Subpopulation 3b was also fenced in 1999 to reduce the risk of plants being trampled.

The Botanic Garden and Parks Authority (BGPA) currently has 48 plants grown from cuttings.
Declared Rare Flora (DRF) markers have been installed at Population 2 and Subpopulations 1a, 1b, 3a, 3b, 4a and 5a.
An information sheet for Grevillea dryandroides subsp. dryandroides was produced using funding jointly supplied by

Plan objective: The objective of this plan is to abate identified threats and maintain or enhance in situ populations to
ensure the long-term preservation of the subspecies in the wild.
Criteria for success: The number of populations has increased and/or the number of mature individuals has increased by
10 per cent or more over the term of the plan.

Translocation (4T) of 135 plants, carried out in May 2000, was unsuccessful due
to the unseasonably dry year. A further translocation of 81 seedlings took place
in July 2003. All seedlings were recorded as dead in 2005.
