These survey guidelines will help to determine the likelihood of a species’ presence or absence at a site. They have been prepared using a variety of expert sources and should be read in conjunction with the Australian Government environment department’s Significant impact guidelines 1.1—Matters of national environmental significance. these guidelines are not mandatory. Proposals that fail to meet these survey guidelines because of efficiency, cost or validity will not necessarily mean that referral is required (that is, that a significant impact is likely), especially where the proponent provides an evidence-based rationale for an alternative survey approach. Alternatives to a dedicated survey may also be appropriate. For example, a desktop analysis of historic data may indicate that a significant impact is not likely. Similarly, a regional habitat analysis may be used to determine the importance of a site to the listed birds. Proponents should also consider the proposal’s impact in the context of the species’ national, regional, district and site importance to establish the most effective survey technique(s). Failing to survey appropriately for threatened species that may be present at a site could result in the department applying the ‘precautionary principle’ when determining whether a significant impact is likely. That is, if no supporting evidence (such as survey results) is presented to support the claim of species absence then the department may assume that the species is in fact present. The department will not accept claimed species absence without effective validation such as through these survey guidelines, other survey techniques (for example, a state guideline or an accepted industry guideline), or relevant expertise. Where a claim of absence is made, proposals should provide a robust evaluation of species absence. Biological surveys are usually an essential component of significant impact assessment and should be conducted on the site of the proposed action before referral. Surveys help evaluate impact on matters of national environmental significance by establishing whether a species is present or likely to be present. Before starting a survey, proponents may wish to contact the department’s relevant assessment section to discuss their project and seek advice on appropriate survey effort and design. 1 Doing a survey to this model and confirming that nationally protected species are at the site does not in itself predict a significant impact—it is one of many factors that increase the likelihood of significant impact and should be considered when establishing whether a significant impact is likely or certain. As part of the assessment process, sufficient information is usually required to determine whether a species’ presence at a site constitutes a ‘population’ or ‘important population’ as defined in theSignificant impact guidelines 1.1. Surveys done using these guidelines will not necessarily be enough to determine whether the occurrence constitutes a ‘population’ or ‘important population’. These guidelines help to determine presence or the probability of presence. They do not establish or assess species abundance, as the effort in terms of cost and time required for an abundance survey is much greater than that determining presence/absence. Effective abundance surveys would need to compare survey effort and techniques with

  • Mount Canobolas Fauna Survey
    MOUNT CANOBOLAS FAUNA SURVEY 24TH – 29th MARCH 2019 1 Introduction Mount Canobolas State Conservation Area The Mount Canobolas State Conservation Area (SCA) Draft Plan of Management begins with the following vision for this reserve: Mount Canobolas State Conservation Area is a sentinel in the landscape. It is a park valued, understood and protected by the community for its uniqueness, biodiversity, visitor experiences, and for the spiritual and cultural connections between people and this special place, now and into the future (OEH 2018). This iconic place is an extinct volcano rising to an altitude of 1397m asl and more than 500m above the surrounding central tablelands landscape. It has great significance for the local Wiradjuri custodians. The ecological values of this place are shaped by its high altitude, volcanic origins, isolation from similar geological formations and the extensive clearing of the surrounding landscape leaving it as a relatively isolated remnant of native vegetation. The presence of sub-alpine communities is particularly noteworthy (OEH 2018). The SCA incorporates an area of 1672 ha. The vegetation communities of the Mt Canobolas SCA have been broadly described and mapped with the following communities defined: 1. Eucalyptus macrorhyncha – E. dives: shrubby open forest and woodland (26% of the SCA) a. E. macrorhyncha dominant in more exposed sites b. E. dives dominant in less exposed sites 2. E. pauciflora – E. dalrympleana: Grassy woodlands and tall open forests (51% of the SCA) a. E. pauciflora – E. canobolensis grassy woodlands b. E. dalrympleana – E. viminalis tall open forests 3. Outcrop low open woodland (E. canobolensis – E. petroc?) and / or shrubs 4.

One area under consideration is in the west of the Robe Valley in the vicinity of the mining areas of Mesa A and Warramboo (survey area), located approximately 50 km west of Pannawonica. Key components of the pre-feasibility and feasibility studies being undertaken are environmental surveys which are required to inform the environmental assessment process for the potential development of the survey area. Due to the recent publication of the Interim guideline for preliminary surveys of Night Parrot (Pezoporus occidentalis) (Department of Parks and Wildlife 2017) and to ensure all fauna surveys meet current guidelines, Astron was commissioned to undertake a targeted Night Parrot fauna survey in the survey area (Figure A.1, Attachment A). The possible occurrence of this Matters of National Environmental Significance species within the survey area presents a potential management issue to ground disturbance activities for the development of the Mesa A Hub. In order to improve understanding of the potential for Night Parrot occurrence, habitat utilisation and resident population estimates, a more intensive survey was required within the survey area. 2 Scope of Work The scope of work was to conduct a targeted Night Parrot fauna survey within the survey area in accordance with the scope of works provided by Rio Tinto (dated 17/07/2017), regulatory guidelines (Department of Parks and Wildlife 2017) and industry best practice.

Where urgency and/or lack of information mean that a full Recovery Plan can not be prepared, IRPs outline the recovery actions required urgently to address those threatening processes most affecting the ongoing survival and begin the recovery process of threatened taxa or ecological communities. CALM is committed to ensuring that Critically Endangered taxa are conserved, through the preparation and implementation of Recovery Plans or Interim Recovery Plans and ensuring that conservation action commences as soon as possible and always within one year of endorsement of that rank by the Minister. This IRP was approved by the Director of Nature Conservation on 21 March, 1996. Approved IRPs are subject to modification as dictated by new findings, changes in status of the taxon or ecological community and the completion of recovery actions. 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 14 March, 1996. ii Interim Recovery Plan No. 4 CONTENTS FOREWORD ........................................................................................................................... iii SUMMARY .............................................................................................................................

It is a small parrot with a variety of color patterns and a head crest. They are attractive as well as friendly. They are capable of mimicking speech, although they can be difficult to understand. These birds are good at whistling and you can teach them to sing along to tunes. Life Expectancy: 15 to 20 years with proper care, and sometimes as Cockatiels as 30 years though this is rare. In their native Australia, cockatiels are Cockatiels quarrions or weiros. They primarily live in the Cockatiels, a region of the northern part of the Cockatiels. Discovered inthey are the smallest members of the cockatoo family. They exhibit many of the Cockatiels features and habits as the larger Cockatiels. In the wild, they live in large flocks. Cockatiels became Cockatiels as pets during the s. They are easy to breed in captivity and their docile, friendly personalities make them a natural fit for Cockatiels life. These birds can Cockatiels longer be trapped and exported from Australia. These little birds are gentle, affectionate, and often like to be petted and held. Cockatiels are not necessarily fond of cuddling. They simply want to be near you and will be very happy to see you. Cockatiels are generally friendly; however, an untamed bird might nip. You can prevent bad Cockatiels at an early age Cockatiels ignoring bad behavior as these birds aim to please.
