Principle 

Requirements 

Assessment based on current survey: 

f) 


It is growing in, or in association 

with, an environment associated 

with a watercourse or wetland. 

No major watercourse or wetlands are 

present in the areas surveyed. 

g) 


The clearing of the land is likely to 

cause appreciable land 

degradation. 

Considered to be unlikely. 

h) 

The clearing of the vegetation is 



likely to have an impact on the 

environmental values of any 

adjacent or nearby conservation 

area. 


Apart from the Koolanooka Hills System 

TEC itself, the nearest conservation area 

is the proposed Bowgada Nature 

Reserve, which is approximately 15 km 

from the project area. 

i) 


The clearing of the vegetation is 

likely to cause deterioration in the 

quality of surface or underground 

water. 


Due to the small area to be cleared it is 

considered unlikely that vegetation 

clearing will affect the quality of surface 

water.  The impact of clearing on 

underground water was beyond the scope 

of this assessment. 

 

j) 


The clearing of the vegetation is 

likely to cause, or exacerbate, the 

incidence or intensity of flooding. 

Considered unlikely due to the small area 

proposed for clearing and the fact that no 

major drainage lines occur in the area.  

The clearing of these drill pads would not 

exacerbate the incidence or intensity of 

flooding compared with the scale of the 

natural flooding events that can occur in 

the area.

Principle 

Requirements 

Assessment based on current survey: 

a) 


It comprises a high level of 

biological diversity. 

During the current survey three proposed 

drill pads and associated track (0.26 ha) 

were assessed.  Thirty three taxa from 21 

families were recorded.  During a survey 

in February 2007 ecologia recorded 130 

taxa from approximately 18 ha surveyed 

over five proposed exploration areas. 

 

DEC recorded 414 taxa from 



approximately 4 ha surveyed.  The lower 

species count from the current survey 

reflects the small area surveyed. 

b) 


It comprises the whole, or a part of, 

or is necessary for the maintenance 

of, a significant habitat for fauna 

indigenous to Western Australia. 

Fauna habitats were not assessed

however, the botanists generally look for 

any fauna of interest while carrying out 

surveys.  No fauna of interest were noted 

during the survey.  The survey area 

occurs within sparse wattle shrubland 

dominated by Acacia acuminata or 

shrubland dominated by Eucalyptus or 



Cyperus pines as described by Beard 

(1976).  These vegetation types are well 

represented in the Yalgoo region.  

c) 


It includes, or is necessary for the 

continued existence of, rare flora. 

The location where the Priority 3 taxon 

Micromyrtus trudgenii

 

was recorded is not 



the only place these plants are found.  

However, Midwest will avoid impact to this 

taxon. 

The collection of Baeckea sp. Mt Gibson 



(R. Meissner & Y. caruso MTGB16) from 

the Blue Hills area is significant, as there 

are only two records for this species at 

the Western Australian Herbarium. 



Baeckea sp. Mt Gibson requires further 

taxonomic study as it is yet to be 

described and is likely to be listed as a 

priority taxon in the future (pers. comm. P. 

Jobson and M. E. Trudgen, 08/08/08).  

Midwest will avoid impact to this taxon. 

d) 

It comprises the whole or a part of, 



or is necessary for the maintenance 

of, a threatened ecological 

community. 

No threatened ecological communities are 

present in the Blue Hills area.  The 

Koolanooka Hills TEC is approximately 

55 km to the east of Blue Hills and will not 

be impacted by the vegetation clearing at 

Blue Hills.

Principle 

Requirements 

Assessment based on current survey: 

e) 


It is significant as a remnant of 

native vegetation in an area that 

has been extensively cleared. 

The old iron ore mining pits, waste rock 

dumps, haul roads and current tracks and 

drill pads are areas where vegetation has 

been cleared.  Past exploration activities 

have occurred at the currently proposed 

exploration area and old tracks and drill 

lines are being used for access to these 

areas wherever possible.  Proposed new 

tracks have been located with care and 

drill pad size will be kept to a minium.  All 

of the above should result in little land 

degradation. 

f) 


It is growing in, or in association 

with, an environment associated 

with a watercourse or wetland. 

No major watercourse or wetlands are 

present in the areas surveyed. 

g) 


The clearing of the land is likely to 

cause appreciable land 

degradation. 

Considered to be unlikely. 

h) 

The clearing of the vegetation is 



likely to have an impact on the 

environmental values of any 

adjacent or nearby conservation 

area. 


The nearest conservation area is the 

proposed Lochada Nature Reserve which 

is approximately 8 km from the project 

area and therefore considered unlikely to 

be impacted by the vegetation clearing. 

i) 


The clearing of the vegetation is 

likely to cause deterioration in the 

quality of surface or underground 

water. 


Vegetation clearing considered unlikely to 

affect the quality of surface water.  An 

ephemeral drainage line was located in 

the vicinity of drill pad MEWB02 but it is 

not anticipated that this will be impacted 

during the planned exploration 

programme.  The impact of clearing on 

underground water was beyond the scope 

of this botanical assessment. 

j) 


The clearing of the vegetation is 

likely to cause, or exacerbate, the 

incidence or intensity of flooding. 

This is considered unlikely due to the 

small area proposed for clearing.

7.0 RECOMMENDATIONS 

It is recommended that Midwest implements the following strategies: 

1.

 

Impact to the two Priority taxa and the species of interest located during the survey 



should be avoided. 

2.

 



Vegetation clearing should be restricted to that which is absolutely necessary and 

raised blade procedures should be used wherever possible. 

3.

 

Avoid and go-round practices should be adopted whenever possible i.e. go around 



trees and large shrubs rather than clear in a straight line. 

4.

 



Previously disturbed areas should be used wherever possible and track widths should 

be minimised. 

5.

 

To avoid the introduction and spread of weed species, Midwest should adhere to 



weed control and hygiene procedures.
