Interim Recovery Plan for Verticordia spicata subsp. squamosa

 

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 Critically Endangered 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 November 1999 to October 2002 but will remain in force until 



withdrawn or replaced. It is intended that, if the taxon is still ranked Critically Endangered, this IRP will be 

replaced by a full Recovery Plan after three years.  

 

This IRP was approved by the Director of Nature Conservation on 2 February 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 November 1999.

BACKGROUND 

 

History 

 

The first collection of Verticordia spicata subsp. squamosa was from east of Three Springs in 1974 and the 



subspecies was described in 1991 (George 1991). Additional populations have since been located, and a total of 

23 plants are now known from seven populations. Three of the populations currently contain no plants, but the 

habitat may still contain propagules for the subspecies. Population 2, for example, has not been seen since 1992 

and it is believed to have been cleared. A new population consisting of one plant was discovered in 1997 near an 

existing population but has yet to be confirmed. 

 

Description 



 

Verticordia spicata subsp. squamosa is a compact shrub to 80 cm tall by 1 m wide with rounded to elliptic 

leaves, 1

⋅5 - 2 mm long. The leaves have prominent oil glands, closely overlap, and are pressed to the stem 

providing the scaly appearance from which this subspecies derives its name (note: squamosus is Latin for scaly). 

The mauve-pink flowers are produced in early summer and are closely packed, forming dense spikes on the 

ends of the branches. The fringed sepals are 3-4 mm long and the petals are 2.5 mm long, with a 1-2 mm fringe. 

The stamens and linear staminodes are hairless. The style is 4 mm long and bearded below the apex. 

 

Verticordia spicata subsp. squamosa differs from the typical subspecies in its smaller leaves and flowers. The 

hybrid with Verticordia comosa has spreading leaves 2-3 mm long, a hypanthium with shorter appendages, 

sepals with prominent auricles and a style 5 mm long with a more dense beard than that of V. spicata subsp



squamosa. Another presumed hybrid has ‘off-white’ flowers, with larger sepals and auricles and a style beard 

with longer hairs. 

 

Distribution and habitat 

 

Endemic to the Three Springs and Mingenew areas of Western Australia, Verticordia spicata subsp. squamosa 



is known from seven populations, most of which are located along narrow road reserves. Populations 4b and 6b 

extend into remnant vegetation on private property, and Population 5 is in a Shire gravel reserve. The subspecies 

has a range of approximately 17 km. 

 

Verticordia spicata subsp. squamosa grows in open mallee over low scrub on deep yellow sands. Associated 

species include Eucalyptus jucunda, Actinostrobus arenarius, Jacksonia sp., Verticordia comosa, V. 



monadelpha, V. densiflora var. stelluligera, V. eriocephala and Grevillea biformis

 

Biology and ecology 

 

The genus Verticordia is well known for its colourful, showy flowers and most taxa in the genus have 



horticultural potential. Few species have proved reliable in cultivation, however, and frequently a large 

percentage of seed is infertile and germination is low (Wrigley and Fagg 1979). Most species make excellent cut 

flowers and a considerable market has been established (Leigh et al. 1984).

Interim Recovery Plan for Verticordia spicata subsp. squamosa 

Propagation of Verticordias has been mainly from cuttings with a few grown from seed. In general, Verticordias 

produce only one seed per flower in the wild. Germination occurs from within old flowers that have fallen to the 

ground. Research by CALM’s Threatened Flora Seed Centre (TFSC) has shown that seed set is generally low in 

Verticordias (less than 51%) and is variable between species, within the same species in different locations, and 

in different years at the same location (Cochrane and McChesney 1995). 

 

Research undertaken in early 1996 on Verticordia spicata subsp. squamosa by the TFSC indicated that 



Population 5 had an average seed set of 10.7% per plant, and Population 3, consisting of a single plant, had a 

seed set of 0.3%. The low seed set for Population 3 has implications for management. 

 

Verticordias are generally considered to be fire sensitive with post fire regeneration occurring mainly from seed. 



A few species have a lignotuber and can resprout after fire. Hybridisation between certain species has been 

noted after fire, however the mechanisms are unknown (E. George

personal communication). 



 

Members of the genus Verticordia are generally not susceptible to infection by Phytophthora spp, however the 

pathogen has been isolated from certain species (M. Grant

2

 personal communication). 



 

Threats 

 

Verticordia spicata subsp. squamosa was declared as Rare Flora in June 1995 and was ranked in September 

1995 as Critically Endangered (CR). It is currently ranked ‘CR’ under IUCN Red List criteria A1c, A2c, B1+2c, 

C1, C2a and D (IUCN 1994) due to its restricted distribution, low numbers of plants and continuing decline in 

the quality of habitat. 

 

Clearing for agriculture around the Three Springs area began early in this century, and has resulted in extensive 



habitat loss. In addition, there has been extensive clearing and widening of road reserves in the Shires of Three 

Springs and Mingenew in the past 10 years. The road reserve at Population 2 was graded in 1990

 

resulting in the 



loss of several plants and significantly reducing the amount of available habitat. The main threats to the 

subspecies are weeds, fire and grazing.

• 

                                                     



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 as they 

produce large amounts of fuel annually. Narrow linear populations such as those on road and rail reserves 

are severely affected by influences from adjacent cleared land. In addition to the proximity of a weed seed 

source, effects include increased wind speed, increased fertiliser runoff, modified hydrology and altered 

disturbance regimes, including fire. 

 

Rabbit warren construction is resulting in soil disturbance at most roadside populations, in particular 

Populations 1 and 3, and Subpopulation 6a. Subpopulation 6b, on private property also contains rabbit 

warrens. Increasing nutrient levels and weeds introduced from rabbit droppings are also impacting on the 

habitat of the subspecies. Grazing may have an impact on the establishment of Verticordia spicata subsp. 



squamosa seedlings thereby limiting natural recruitment. 

 

Inappropriate fire regimes would adversely affect the viability of populations, as seeds of Verticordia 



spicata subsp. squamosa probably germinate following fire. If this is the case, the soil seed bank would be 

rapidly depleted if fires recurred before regenerating or juvenile plants reached maturity and replenished the 

soil seed bank. However, it is likely that occasional fires are needed for reproduction of this subspecies

High fire frequency also results in a temporary increase in the availability of nutrients, and this favours 



weed establishment (Panetta and Hopkins 1991). 

 

Road maintenance activities threaten plants and habitat at road reserve populations of Verticordia spicata 

subsp. squamosa. This includes actions such as grading the road reserves, constructing drainage channels 

and mowing the roadside vegetation to improve visibility. These disturbance events also often encourage 

weed invasion into adjacent habitat. Relevant authorities need to be informed of the location of road reserve

populations so that the habitat can be protected. Adjacent landowners also need to be informed of the 



presence of this subspecies to prevent possible grazing damage.

RECOVERY OBJECTIVES AND CRITERIA 

 

Objective 

 

The objective of this Interim Recovery Plan is to abate identified threats and maintain viable in situ populations 



to ensure the long-term preservation of the species in the wild. 

 

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 

 

All appropriate land managers have been made aware of the existence of this taxon and its locations. Local 



Shires and private property owners have been formally notified of the presence of Verticordia spicata subsp. 

squamosa populations on their lands.

 

These notifications detailed the Declared Rare status of the taxon and the 



associated legal responsibilities.  

 

Declared Rare Flora (DRF) markers have been installed at Populations 1, 3 and 7, and Subpopulation 6a. These 



alert people working in the area to the presence of significant flora, and help to prevent accidental damage. 

Awareness of the significance of these markers is being promoted to relevant land managers such as local 

authorities. To this end, 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.

Interim Recovery Plan for Verticordia spicata subsp. squamosa 

 

Cutting material of Verticordia spicata subsp. squamosa was collected by Botanic Gardens and Parks Authority 



(BGPA) staff in 1995. In February 1996, 138 cuttings were successfully growing in the nursery. All germinants, 

except one clone, have since died, suggesting that the species is quite difficult to propagate. CALM’s 

Threatened Flora Seed Centre (TFSC) collected seed from four populations in January 1996 and this is being 

stored at -18

°C. Further collections were made in 1997 and 1998. The TFSC tests the viability of the seed 

initially, after one year in storage, and again after five years. The initial germination rate of this seed was found 

to range from 6% to 86%, and after one year in storage was 33%. 

 

Research into the reproductive biology, seed bank dynamics and seed germination physiology (particularly the 



response to smoke) is being undertaken on several species of Verticordias  including  V. spicata subsp. 

squamosa, by CALM’s Western Australian Herbarium and the BGPA.  

 

Populations (4b and 6b) on private property were fenced in 1997 to prevent sheep grazing and trampling plants 



and habitat.  

 

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



actions, has been developed for Verticordia spicata subsp. squamosa. It is hoped that the poster will result in the 

discovery of new populations. 

 

The Moora and Geraldton District Threatened Flora Recovery Teams are overseeing the implementation of this 



IRP and will include information on progress in annual reports to CALM’s Corporate Executive and funding 

bodies. 


 

CALM staff from the Moora and Geraldton District Offices regularly monitor the populations. 

 

Future recovery actions 

 

Where populations occur on lands other than those managed by CALM, permission has been or will be sought 



from the appropriate land managers prior to recovery actions being undertaken. 

 

1. 



Coordinate recovery actions 

 

The MDTFRT and GDTFRT will continue to oversee the implementation of the recovery actions for 



Verticordia spicata subsp. squamosa

 

Action: 

Coordinate recovery actions 

Responsibility: 

CALM (Moora and Geraldton Districts) through the MDTFRT and GDTFRT 



Cost: 

$4900 per year 



 

2.  

Install Declared Rare Flora markers 

 

The requirement for Declared Rare Flora (DRF) markers at Subpopulation 4a will be investigated and markers 



installed as necessary. 

 

Action: 



Install Declared Rare Flora markers 

Responsibility: 

CALM (Moora and Geraldton Districts) through the MDTFRT and GDTFRT 

Cost: 


$600 in first year 

 

3. 



Implement weed control 

 

Weeds are a threat to all populations and effective weed control with the use of herbicides and hand pulling is 



required. The tolerance of native plant species to herbicides at Verticordia spicata subsp.  squamosa sites is 

unknown and weed control programs will be undertaken in conjunction with research. The aim of weed control 

is to maintain the pre-invasion condition of the habitat (prevention), control or arrest ongoing weed invasion 

(intervention) and reverse the degraded condition of the habitat where applicable (rehabilitation) (Panetta and 

Hopkins 1991)The following actions will be implemented: 

 

7



Interim Recovery Plan for Verticordia spicata subsp. squamosa

 

 



1.  Selection of appropriate herbicides after determining which weeds are present. 

2.  Controlling invasive weeds by hand removal or spot spraying around Verticordia spicata subsp. squamosa 

plants when weeds first emerge. 

3.  Scheduling weed control to include spraying at other threatened flora populations within the district 

wherever possible. 

 

Action: 

Undertake weed control 

Responsibility: 

CALM (Moora and Geraldton Districts, CALMScience) through the MDTFRT and  

 GDTFRT 

Cost: 

$1700 per year 

 

4. 

Undertake rabbit control 

 

Disturbance of the soil due to rabbit warren construction, and increased nutrient levels and the introduction of 



weeds from their droppings are affecting the habitat at most roadside populations (1, 3, 6a), and one private 

property population (6b). Rabbit control by annual 1080 baiting is therefore required. Baiting will be undertaken 

twice a year during summer in conjunction with the shire’s and local farmers' baiting programs. 

 

Action:  

Undertake rabbit control 

Responsibility: 

CALM (Moora and Geraldton Districts) through the MDTFRT and GDTFRT 



Cost: 

$900 per year 

 

5. 

Liaise with relevant land managers 

 

Staff from CALM's Moora and Geraldton Districts will continue to liaise with appropriate landowners to ensure 



the populations are not accidentally damaged or destroyed. 

 

Action: 

Liaise with relevant land managers 

Responsibility: 

CALM (Moora and Geraldton Districts) through the MDTFRT and GDTFRT 



Cost:  

$700 per year 

 

6. 

Develop and implement a fire management strategy 

 

Fire appears to kill adult plants of the species, and regeneration is likely to be largely from seed. Frequent fire 



may therefore prevent the accumulation of sufficient soil stored seed to allow regeneration of the populations. A 

fire management strategy will be developed to determine fire control measures and fire frequency. 

 

Action: 

Develop and implement a fire management strategy 



Responsibility: 

CALM (Moora and Geraldton Districts) through the MDTFRT and GDTFRT 



Cost: 

$2400 in first year, and $1000 in subsequent years 

 

7. Monitor 

populations 

 

Monitoring of factors such as weed invasion, habitat degradation, salinity and population stability (expansion or 



decline), pollinator activity, seed production, recruitment, and longevity is essential. The populations will be 

inspected annually. 

 

Action: Monitor 

populations 



Responsibility: 

CALM (Moora and Geraldton Districts) through the MDTFRT and GDTFRT 



Cost: 

$800 per year 

 

8. 

Conduct further surveys 

 

Opportunistic surveys by CALM Moora District and CALMScience staff have located several new populations 



of Verticordia spicata subsp. squamosa in recent years. Reserves and other areas of native vegetation containing 

suitable habitat in the Shires of Mingenew and Three Springs need to be surveyed on a systematic basis for the

presence of the subspecies, particularly during the flowering period of October-December several years 

following disturbances such as fire. Local volunteers such as members of naturalists clubs and the Wildflower 

Society will be encouraged to be involved in surveys supervised by CALM staff. 

 

Action: 

Conduct further surveys 



Responsibility: 

CALM (Moora and Geraldton Districts) through the MDTFRT and GDTFRT 



Cost: 

$2000 per year 

 

9. 

Create buffers and rehabilitate habitat 

 

Buffers will be created and the habitat of Populations 4b and 6b will be rehabilitated using plant species 



endemic to the site. Rehabilitation will ideally extend beyond the current boundary of Verticordia spicata subsp. 

squamosa populations to provide a stable buffer to discourage weed invasion. 

 

Action: 

Create buffers and rehabilitate habitat 

Responsibility: 

CALM (Moora and Geraldton Districts) through the MDTFRT and GDTFRT 



Cost: 

$7100 in the second year 

 

10.  Collect seed and cutting material 

 

The viability of seed collected by the TFSC is generally very low, and survival of plants propagated from 



cutting material has been extremely poor. Further collections of seed and cutting material are required, 

particularly to provide material for future translocations. This will be coordinated between the Moora and 

Geraldton District Threatened Flora Recovery Teams and the BGPA. 

 

Action: 

Collect seed and cutting material 

Responsibility: 

CALM (Moora and Geraldton Districts, TFSC) and BGPA, through the MDTFRT and  

 GDTFRT 

Cost: 

$3000 per year 

 

11. Promote 

awareness 

 

The importance of biodiversity conservation and the protection of the Critically Endangered Verticordia spicata 



subsp.  squamosa  will be promoted to the public. Formal links with local naturalist groups and interested 

individuals will also be encouraged. 

 

Action: Promote 

awareness 



Responsibility: 

CALM (Moora and Geraldton Districts, Corporate Relations) through the MDTFRT  

 and 

GDTFRT 


Cost: 

$900 per year 



 

12.   Start translocation process 

 

Translocation is essential for the conservation of this species, as the total number of extant plants is low, and 



known populations are not secure from threats including road maintenance, weeds, rabbits and fire. Although 

translocations are generally undertaken under full Recovery Plans, it is possible to develop a Translocation 

Proposal and start propagating plants within the time frame of an Interim Recovery Plan. This will be 

coordinated by the MDTFRT and the GDTFRT. Information on the translocation of threatened animals and 

plants in the wild is provided in CALM Policy Statement No. 29 Translocation of Threatened Flora and Fauna. 

All translocation proposals require endorsement by the Director of Nature Conservation. 

 

Action: 

Start translocation process 



Responsibility: 

CALM (CALMScience, Moora and Geraldton Districts) through the MDTFRT and 

  

GDTFRT 


Cost:  

$1800 in the third year

13.   Write full Recovery Plan 

 

At the end of the three-year term of this Interim Recovery Plan, the need for further recovery will be assessed. If 



the species is still ranked Critically Endangered, a full Recovery Plan will be developed to describe action 

required for long-term maintenance. A Recovery Plan will be prepared with  the benefit of knowledge gained 

over the time frame of this Interim Recovery Plan.

TERM OF PLAN 

 

This Interim Recovery Plan will operate from November 1999 to October 2002 but will remain in force until 



withdrawn or replaced. It is intended that, if the taxon is still ranked Critically Endangered, this IRP will be 

replaced by a full Recovery Plan after three years.
