1.1  Impacts to restricted communities/associations 

 

Issue 1 

PER 

modified

The proposal will considerably impact the known extent of two 

restricted communities; Juncus kraussii closed sedgeland on swale 

(vegetation sub-association 2) and Grevillea-Melaleuca and other low 

shrubs over Borya sphaerocephala mats on laterite/sandstone 

(vegetation sub-association 8).  

 

The PER is misleading and pre-emptive in its anticipation that further 



survey will extend the known extent of these communities. This is 

particularly the case for sub-association 8 

No 

 

Vegetation Sub-Association 2 



As outlined previously, vegetation sub-association 2 is situated alongside and down-

gradient of the proposed land based dredge disposal area and the substantial iron 

ore stockyard.  This area of vegetation is likely to be subject to indirect impacts from 

the location of this infrastructure, primarily due to localised changes in surface and 

shallow groundwater hydrology arising from the water draining and infiltrating away 

from the dredge disposal area.  For the purpose of impact assessment, Oakajee Port 

and Rail Pty Ltd (OPR) has anticipated that most, if not all, of the sub-association in 

proximity to the Proposal infrastructure could be lost.  OPR is investigating 

practicable measures to manage this issue but cannot be certain that it will be able to 

prevent indirect changes in vegetation down-gradient of the dredge disposal area.  

This vegetation unit corresponds to that described within the Geraldton Regional 

Flora and Vegetation Survey (GRFVS) as Community 4: Swale: Ficinia nodosa.  

Further examination of the area has established that a small portion is dominated by 

Ficinia nodosa and the majority of this community is dominated by Juncus kraussii. 

Ecologia conducted an additional and broader survey in March 2010 which confirmed 

that vegetation sub-association 2 was likely to occur further afield, specifically at least 

in two additional locations in proximity to Port Gregory, approximately 60 km north of 

the Study Area and the northern boundary of the GRFVS area (Figure 7.3, Table 7.3 

and 7.4 within the Port Terrestrial Public Environmental Review (PER). 

Table 7-3 and 7-4 as outlined within the Port Terrestrial PER are depicted as Table 1 

and 2 in this Response to Submissions document, respectively.  Table 1 outlines the 

current known Juncus kraussii locations within proximity of the Proposal, whilst Table 

2 is a summary of Table 7-4 as outlined within the Port Terrestrial PER, which 

identifies the study area impacts to vegetation sub-association 2.

 For sub-association 2 Juncus kraussii, a revised Study Area extent and additional areas identified by 

Ecologia (2010b) surveys to the north of Port Gregory, have been included within the total areas and 

impact calculations, see more detailed discussion above and Appendix C of the PER (Ecologia 2010b).  

Otherwise, the known extent is based on data from the Study Area (Ecologia, 2010a).   

 

The March 2010 survey was not exhaustive due to private land access constraints 



and it remains highly probable that additional locations occur within the Geraldton 

Sandplains Bioregion because of the occurrence of the areas that are similar in 

topography, soils and coastal proximity to that which this sub-association has been 

found.  An examination of high resolution aerial imagery of the area surrounding the 

Study Area was recently conducted for the purpose of locating further potential 

populations.  However, it is difficult to detect this community within available imagery 

as it tends to occur in very small, narrow areas within the swales of dunes and is not 

highly coloured or have a distinct appearance from surrounding vegetation. 

 

Notwithstanding this limitation, several additional potential locations have been 



identified to the south of the Study Area, which will require inspection to confirm 

species composition (as depicted in Figure 1). 

The regional significance of this sub-association is not clearly established.  The lack 

of mapping regionally is likely to be at least partially attributable to the very small 

scale at which it occurs rather than its rarity (Ecologia, 2010b).  Surveys of areas 

containing this community type which did not directly sample locations at which it 

occurs may incorporate those areas into broader community types.  An examination 

of Western Australian Herbarium records for Ficinia nodosa and Juncus kraussii 

indicates that a subset of the lodged specimens for this species occur across a broad 

range of habitats that are very similar to that presented within the Study Area 

(seasonally damp areas in the swales of coastal dunes) with a similar suite of 

associated specimens (Table 3).  In many instances there is insufficient detail within 

the voucher notes regarding associated species and vegetation structure to establish 

how closely the vegetation at these locations correlates to that present within the Port 

Study Area; however, it does demonstrate that these species have an extremely 

large range and that they do occur in similar landforms to those identified at Oakajee.  

Given that neither Ficinia nodosa nor  Juncus kraussii are Priority taxa, specimens 

would not be mandatorily lodged with the Herbarium for all surveys in which they 

were collected.  Hence the vouchered specimens are likely to underestimate the 

likely distribution of these two species within this or any other community type.  

The widespread nature of these species (J. kraussii and F. nodosa) and, what 

appears to be a common occurrence within coastal swale systems suggests that this 

sub-association is highly likely to be commonly found at other locations to the north 

and south of the Proposal area.  On this basis, OPR is of the view that this sub-

association is not restricted and is therefore unlikely to be of conservation 

significance.   

Notwithstanding this, OPR has commissioned further aerial photo review and 

supporting field inspections, to verify additional locations of vegetation sub-

association 2, which will occur in mid to late October 2010.  The study results will 

further assist OPR in developing an appropriate management strategy for this 

vegetation sub-association.
