Interim Recovery Plan for Grevillea dryandroides subsp. dryandroides  

 

FOREWORD 

 

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. 

 

IRPs outline the recovery actions that are required to urgently address those threatening processes most 



affecting the ongoing survival of threatened taxa or ecological communities, and begin the recovery process. 

 

CALM is committed to ensuring that CR taxa are conserved through the preparation and implementation of 



Recovery Plans or Interim Recovery Plans and by ensuring that conservation action commences as soon as 

possible and always within one year of endorsement of that rank by the Minister.  

 

This Interim Recovery Plan will operate from April 2000 to March 2003 but will remain in force until 



withdrawn or replaced. It is intended that, if the taxon is still ranked CR, this IRP will be replaced by a full 

Recovery Plan after three years.

  

 

This IRP was approved by the Director of Nature Conservation on 20 August 2000. The provision of funds 



identified in this Interim Recovery Plan is dependent on budgetary and other constraints affecting CALM, as 

well as the need to address other priorities. 

 

Information in this IRP was accurate at April 2000.

Current status: Grevillea dryandroides subsp. dryandroides was declared as Rare Flora in October 1996 and 

was ranked as Critically Endangered (CR) in February 1997. It currently meets World Conservation Union 

(IUCN) Red List Category ‘CR’ under criteria B1+2b,c,d,e and C1 (IUCN 1994), due to there being just five 

small highly fragmented populations, a decline in the area of occupancy and the quality of its habitat (mainly on 

disturbed road and rail reserves), and a continuing decline in the number of individual plants. The main threats 

include weeds, accidental destruction through road and rail maintenance and recreational activities, fire and 

competition from associated native plant species. 

 

Habitat requirements: Grevillea dryandroides subsp. dryandroides is endemic to Western Australia where it is 

apparently confined to the Ballidu area. It is known from five populations containing 115 plants in open heath 

on grey sandy loam and yellow gravelly sand, with shrubs of Allocasuarina and Melaleuca

 

Critical habitat: The critical habitat for Grevillea dryandroides subsp. dryandroides comprises the area of 

occupancy of the known populations; areas with open heath on grey sandy loam and yellow gravelly sand, with 

shrubs of Allocasuarina and Melaleuca within 200 metres of known populations; corridors of remnant 

vegetation that link populations; additional areas with open heath on grey sandy loam and yellow gravelly sand, 

with shrubs of Allocasuarina and Melaleuca and that do not currently contain the subspecies. 

 

Existing Recovery Actions: The following recovery actions have been or are currently being implemented: 

1.

 

Appropriate land managers have been informed of the subspecies’ location and their legal obligations. 



2.

 

Declared Rare Flora (DRF) markers have been installed at populations 2 and 4, and subpopulations 1a, 1b, 



3a and 5a.

BACKGROUND 

 

History 

 

The genus Grevillea is named in honour of Charles Greville, a past Vice President of the Royal Society who 



introduced and cultivated many Australian plants in England. Some 340 species are known, most of which 

occur in Australia with some 150 found in the South-western Botanical Province of Western Australia. Here, 

they are concentrated on the sandheaths and lateritic rises of the kwongan, often in association with granite 

outcrops (Olde and Marriott, 1994).  

 

Based on the persistence of foliar indumentum, leaf lobe length, conflorescence and pistil length



Grevillea dryandroides has been split into two subspecies (Olde and Marriott, 1993). G.  dryandroides 

subsp. dryandroides differs from the subspecies hirsutus in having smooth leaves with lobes that are less 

than 12 millimetres long. 

 

W.E. Blackall made the first collection of Grevillea dryandroides subsp. dryandroides from the Pithara area in 



1931. Further collections were made from Ballidu, Pithara and Wubin between 1934 and 1996. Despite recent 

surveys in these areas only five populations are currently known from a single area near Ballidu. 

 

Most  Grevillea dryandroides subsp. dryandroides populations are located on road and rail reserves and are 



therefore particularly vulnerable to maintenance such as firebreak grading, cable installation, weedicide 

application and tourist visitation.  

 

Grevillea dryandroides subsp. dryandroides was declared as Rare Flora in October 1996 and was ranked as 

Critically Endangered (CR) in February 1997. It currently meets World Conservation Union (IUCN) Red List 

Category ‘CR’ under criteria B1+2b,c,d,e and C1 (IUCN 1994), due to there being just five small highly 

fragmented populations, a decline in the area of occupancy and the quality of its habitat (mainly on disturbed 

road and rail reserves), and a continuing decline in the number of individual plants. 

 

Description 

 

Grevillea  dryandroides subsp. dryandroides is a root suckering shrub to 50 centimetres 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 15 millimetres long. The inflorescence is 3 to 4 centimetres long, and 

pedicles are 1 to 1.5 millimetres 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 to7 millimetres long and the pistil 17 to 18 millimetres 

long (Olde and Marriott, 1993). Flowers occur from September to March (Brown et al., 1998).

Distribution and habitat 

 

Grevillea dryandroides subsp. dryandroides is endemic to Western Australia where it is apparently confined to 

the Ballidu area. It is known from five populations that include 115 plants. 

 

Grevillea dryandroides subsp. dryandroides is found in open heath on grey sandy loam and yellow gravelly 

sand, with shrubs of Allocasuarina and Melaleuca. Associated species include Acacia resinimargineaAcacia 

yorkrakinensis subsp. acrita,  Acacia sessilispica,  Dampiera lavandulacea,  Calytrix breviseta subsp. stipulosa

Chorizema rhynchotropisOpercularia spermacoceaMelaleuca cordataWaitzia acuminataHakea scoparia

Allocasuarina campestrisStylidium sp., Conospermum stoechadis subsp. ?sclerophyllumSynaphea sp., Hakea 

meisneriana,  Glischrocaryon aureum var. aureum,  Jacksonia sp., Melaleuca conothamnoides,  Verticordia 

chrysantha,  Petrophile incurvata,  Melaleuca uncinata,  Melaleuca orbicularis,  Verticordia sp., Hibbertia 

huegelii, and Thryptomene sp. 

 

Critical Habitat 

 

Critical habitat is habitat identified as being critical to the survival of a listed threatened species or listed 



threatened ecological community. Habitat is defined as the biophysical medium or media (a) occupied 

(continuously, periodically or occasionally) by an organism or group of organisms; or (b) once occupied 

(continuously, periodically or occasionally) by an organism, or group of organisms, and into which organisms 

of that kind that the potential to be reintroduced. (sections 207A and 528 of Commonwealth Environment 



Protection and Biodiversity Conservation Act 1999 (EPBC Act)). 

 

The critical habitat for Grevillea dryandroides subsp. dryandroides comprises: 



 

the area of occupancy of the known populations, 



 

areas of similar habitat ie. open heath on grey sandy loam and yellow gravelly sand, with shrubs of 



Allocasuarina and Melaleuca, within 200 metres of known populations (these provide potential habitat for 

natural range extension), 

 

corridors of remnant vegetation that link populations (these are necessary to allow pollinators to move 



between populations and are usually road and rail verges), 

 



additional occurrences of similar habitat ie. open heath on grey sandy loam and yellow gravelly sand, with 

shrubs of Allocasuarina and Melaleuca (this represent possible translocation sites). 



 

Biology and ecology 

 

It is known that the subspecies is pollinated by birds and regenerates from seed or suckers after fire or 



disturbance (Olde and Marriott, 1995). Smoke trials undertaken by the Botanic Parks and Gardens Authority 

(BGPA) in 1995 on two adult plants supports this hypothesis, with up to 60 seedlings germinating in a 15 metre 

radius around the plants. Otherwise the biology and ecology of Grevillea dryandroides subsp. dryandroides is 

poorly known. 

 

Some minor seed predation has been observed but not enough to prevent a large amount being stored in the soil.  



 

Threats 

 

The main threats include weeds, accidental destruction through road and rail maintenance and recreational 

activities, fire and competition from an associated native plant species.  

 



 

Weed  invasion is a threat to all populations. Weeds suppress early plant growth by competing for soil 

moisture, nutrients and light. They also exacerbate grazing pressure and increase the fire hazard due to their 

high fuel loads. Narrow, linear populations, such as road and rail reserves, are severely affected by weed 

seed blown in from adjacent cleared land (Lynch 1987; Saunders et al. 1987; Taylor 1987). 



 

 



Road and track maintenance threatens population 2 and subpopulations 1a, 1b, 3a, 3c, 5a and 5b. Threats 

include maintenance of telephone cables located underneath subpopulation 3a, grading of road reserves, 

spraying of chemicals, construction of drainage channels and mowing of roadside vegetation. These events 

often encourage weed invasion as well as causing damage to actual plants. Relevant authorities need to be

Interim Recovery Plan for Grevillea dryandroides subsp. dryandroides  

 

informed of the location of populations so that appropriate protective measures can be implemented. 



Adjacent landowners should also be informed to prevent possible damage due to grazing, crop maintenance, 

firebreak maintenance or other activities that may threaten the populations.  



 

 



Lack of population recruitment has been observed at all populations. Possible causes include seed and/or 

seedling predation and a lack of disturbance events to stimulate germination.  



 

 



Human activities threaten subpopulation 3b and population 4, both of which are located in Shire reserves. 

Threats include trampling by people, accidental mowing and construction of new graves.  

 



 



Inappropriate fire regimes may affect the viability of plants. Seed of Grevillea dryandroides subsp. 

dryandroides probably germinates following fire and occasional fires are needed for recruitment. No natural 

fire has occurred in the area of the populations in recent times. Too frequent fire may rapidly deplete the soil 

seed bank if it occurs before plants have reached maturity. It could also deplete nutrients stored in the roots 

and so affect the plants' capacity to resprout. Further investigation is required and will be addressed in 

management action 9.  

 



 

Competition from a local dodder species (Cuscuta sp.) is a threat to subpopulations 1b and 5b, as the vine 

covers many adult plants. Dodder not only competes for light, nutrients and possibly pollinators but also 

physically restricts the host, therefore posing an immediate threat to the longevity of individual plants.

Guide for decision-makers 

 

Section 1 provides details of current and possible future threats. Developments in the immediate vicinity of any 



of the populations or within the defined critical habitat of Grevillea dryandroides subsp. dryandroides require 

assessment. No developments should be approved unless the proponents can demonstrate that they will have no 

significant impact on the subspecies, and its habitat or potential habitat.

Criterion for success: The number of individuals within populations and/or the number of populations have 

increased. 



Criterion for failure: The number of individuals within populations and/or the number of populations have 

decreased. 

 

3. RECOVERY 

ACTIONS 

 

Existing recovery actions 

 

Local Shires and private property owners have been formally notified of the presence of populations of 



Grevillea dryandroides subsp. dryandroides on their lands. Notifications detail the Declared Rare status of the 

taxon and the associated legal responsibilities.  

 

Declared Rare Flora (DRF) markers have been installed at populations 2 and 4, and subpopulations 1a, 1b, 3a 



and 5a. DRF markers alert people working in the area of the presence of threatened flora, and help prevent 

accidental damage. An increased awareness of these markers is being promoted to relevant land managers such 

as local authorities. Dashboard stickers and posters have been produced and distributed. These illustrate DRF 

markers, inform of their purpose and provide a contact telephone number to use if such a marker is encountered. 

 

An A4 sized poster, which provides a description of the subspecies, and information about threats and recovery 



actions, has been developed for Grevillea dryandroides subsp.  dryandroides. It is hoped that the poster will 

result in the discovery of new populations. 

 

A reply paid postal drop illustrating Grevillea dryandroides subsp. dryandroides and describing its distinctive 



features and habitat has been distributed by CALM’s Merredin District office to local farmers and residents in 

the Wongan-Ballidu Shire. Postal drops aim to provide information about threatened species and a contact name 

and number. It is hoped that by targeting residents of specific areas new populations will be located.  

 

Subpopulation 1b was fenced following the destruction of ten plants during firebreak grading and weedicide 



activities in 1991. Subpopulation 3b was fenced in 1999 to reduce the risk of plants being trampled. 

 

Seed was collected from populations 1 and 5 in November 1996, 1997, 1998 and 1999 and stored in CALM’s 



Threatened Flora Seed Centre. A total of 604 seeds have been collected from approximately 20 plants and these 

are being stored at -18

C. The initial germination rate of Grevillea dryandroides subsp. dryandroides seed was 

found to range between 40 and 100%. A sample germinated after one year in storage gave an 80% germination 

rate. 

 

Eighteen cuttings were collected by staff from the Botanic Gardens and Parks Authority (BGPA) in 1994 and a 



further ten in 1997. The success rate of these cuttings has been low with only six plants from the first batch and 

one plant from the second batch surviving. Material was also collected by BGPA for tissue culture in 1997. The 

TFSC propagated six seedlings in 1997, with three still alive. 

 

Thirty  Grevillea dryandroides subsp. dryandroides cuttings were taken in 1999 and are currently being 



propagated at BGPA for a potential translocation. 

 

Smoke trials undertaken by BGPA in 1995, on two adult Grevillea dryandroides subsp. dryandroides plants 



resulted in 50 to 60 seedlings germinating in a 15 metre radius around the plants. 

 

The Merredin District Threatened Flora Recovery Team is overseeing the implementation of this IRP and will 



include information on progress in annual reports to CALM’s Corporate Executive and funding bodies. 

 

CALM’s Merredin District Office staff regularly monitor all populations. 



 

Future recovery actions 

 

Where recovery actions are implemented on lands other than those managed by CALM, permission has been or 



will be sought from the appropriate land managers prior to actions being undertaken.

Interim Recovery Plan for Grevillea dryandroides subsp. dryandroides  

 

11. 

Undertake and monitor translocation 

 

Although translocations are generally undertaken under full RPs, the many threats to wild populations of this 



CR subspecies require the development of an urgent translocation proposal within the time frame of this IRP. 

This will be coordinated by the MDTFRT. A translocation proposal has been approved for this subspecies. 

 

A translocation site has been selected which contains healthy remnant vegetation, is relatively free of weeds, 



and contains a similar soil type, associated vegetation and structure to that of the known populations. The site is 

also adjacent to Population 2, therefore the translocation can be considered a restocking under the definitions 

provided by Policy Statement 29 and the guidelines for translocation of threatened plants in Australia. An 

irrigation system will be set up during planting out of seedlings. Monitoring of the translocation is essential and 

will occur during the flowering period of the subspecies. 

 

Action: 

Undertake and monitor translocation 

Responsibility: 

CALM (CALMScience, Merredin District) through the MDTFRT 



Cost:  

$11,500 in first year, and $5,600 in subsequent years. 

 

12. Promote 

awareness 

 

The importance of biodiversity conservation and the protection of the CR Grevillea dryandroides subsp. 



dryandroides will be promoted to the public. Formal links with local naturalist groups and interested individuals 

will also be implemented.  

 

Action: Promote 

awareness 



Responsibility: 

CALM (Merredin District, Corporate Relations) through the MDTFRT 



Cost:  

$600 per year. 

 

13. 

Write a full Recovery Plan 

 

At the end of the three year term of this IRP, the need for further recovery will be assessed. If the subspecies is 



still ranked CR a full RP will be developed. A RP will be prepared with the benefit of knowledge gained over 

the time frame of this IRP. 

 

Action: 

Write a full Recovery Plan 



Responsibility: 

CALM (WATSCU, Merredin District) through the MDTFRT 



Cost:  

$16,500 in third year. 

 

4. TERM 

OF 

PLAN 

 

This IRP will operate from April 2000 to March 2003 but will remain in force until withdrawn or replaced. It is 



intended that, if the taxon is still ranked CR, this IRP will be replaced by a full RP after three years.

Discussion 

 

Two subspecies are here recognised based on the persistence of foliar indumentum, leaf lobe length, 

conflorescence and pistil length.
