PREVIOUS SURVEYS WITHIN THE PROJECT AREA AND 

REGION 

Mapping of structural plant communities within the Mullering area (located within the 

Cooljarloo West project area) was undertaken by Woodman Environmental in 2005 and 

2006 to support an environmental management plan for the proposed Empire Oil 

Mullering Onshore 3D Seismic Survey program (WEC 2006b). A total of 454 native 

plant taxa and 32 introduced species were recorded within the Mullering project area. 

The Declared Plant (weed) Moraea flaccida was recorded during the surveys. This 

species is listed as a P1 species, prohibiting the movement of plants, seeds and 

contaminated machinery within the state (DAF 2009).

Flora and Vegetation Assessment 

Woodman Environmental has conducted numerous surveys within the Falcon area to 

identify, assess and manage risks to flora and vegetation associated with proposed 

mining operations and potential drawdown impacts (WEC 2006a, 2007a, 2009). A total 

of 391 native plant taxa and 23 introduced (weed) taxa have been recorded within the 

Falcon project area during studies conducted by Woodman Environmental between 

2005 and 2008. A total of 23 DRF and Priority Flora species were recorded during the 

surveys (Table 2).

A total of 11 Floristic Community Types (FCTs) within 2 supergroups were mapped 

and described within the Falcon area during the quantitative surveys (WEC 2009). 

Supergroup 1 represented Heath, Scrub and Forest sites in wet areas on lowerslopes, 

flats, drainage lines and basins. Supergroup 2 comprised woodlands and heaths on 

deeper sands on mid to upperslopes and swales.

None of the FCTs recorded within the Falcon project area corresponded with listed 



Threatened Ecological Communities (TECs) as defined by the Department of 

Environment and Conservation (2009e). The most restricted FCTs recorded were FCT 6 

and FCT 7. 

 

Woodman Environmental conducted a survey for DRF species along proposed drill 



lines within the Cooljarloo West project area during 2006 (WEC 2007b). A total of 

three DRF species were recorded during the surveys as listed below: 

 

Andersonia gracilis   

 

 



 

DRF 


Anigozanthos viridis subsp. terraspectans  

DRF 


Macarthuria keigheryi

Western Botanical (2004) undertook a survey of 24 proposed drill lines located within 



the Falcon lease areas (Retention License 70/15) in 2004.  A total of nine Priority Flora 

species, one possible DRF species, and two undescribed species were recorded during 

the survey.  Priority Flora species recorded were: 

 

Conospermum scaposum P3 



Banksia dallanneyi  subsp. pollosta   

 

P3 



Banksia tortifolia 

 

 



 

 

P3 



Hensmannia stoniella

P4 



Banksia platycarpa

Potentially  Anigozanthos viridis subsp. terraspectans (DRF) was recorded, however 

specimens were unable to be positively identified at the time.  Two potentially new 

species, Dryandra nivea subsp. Cooljarloo (G Cockerton 3423) and Isopogon buxifolius 

subsp. Cooljarloo (GC 2001) were also recorded, however specimens of these were not 

vouchered at the Western Australian Herbarium (WAHerb), and are currently 

unrecognised by the WAHerb.  The collection historically recorded by Western 

Botanical (2004) as Isopogon buxifolius subsp. Cooljarloo (GC 2001) correlates with 

Isopogon sp. Badgingarra (A.S. George 14200) (P1). In addition, the collection 

Dryandra nivea subsp. Cooljarloo (G Cockerton 3423) is now considered to be Banksia 

nivea subsp. nivea (pers. comm. A. George). 

Rockwater Pty Ltd (2008) undertook a survey of 365 drill holes along approximately 

117km of drill lines and access tracks within exploration tenements 70/2345 and 

70/2346 in 2008. A total 21 Priority Flora species and four DRF species were recorded 

during the survey as listed below:

Recent taxonomic work conducted by Greg and Bronwen Keighery of the Department 

of Environment and Conservation have identified additional new taxa within the region 

of the project area. Grevillea thelemanniana subsp. Coojarloo (B.J. Keighery 28 B) P1 

was previously recognized as Grevillea preissii and is now considered to be 

conservation significant. This species has been collected by Woodman Environmental 

within the Mullering area (WEC 2006b) and Falcon area (WEC 2009). Petrophile sp. 

Coojarloo (name unpublished) has been collected further west of the Coojarloo West 

project area within remnant vegetation adjacent to Woolka Rd. This species is currently 

being considered to be given a conservation status of P1 in the near future.
