1.0 INTRODUCTION AND BACKGROUND During the EIS for the proposed SunCoast Power Project, which will see the construction of a new 132 kV transmission line from Palmwoods to west Maroochydore, Platypus (Ornithorhynchus anatinus) were recorded within sections of Eudlo Creek, Chevallum (Energex, 2008). Additional flora and fauna assessments undertaken in 2010 again recorded Platypus within the Eudlo Creek catchment (GHD 2010). Although not listed as a threatened under the state Nature Conservation Act 1992 (NCA) or federal Environment Protection and Biodiversity Conservation Act 1999 (EPBC), Platypus is listed as culturally significant (NCA) and is recognised as a charismatic Australian species that is considered important by the general public. In consideration of public concern regarding the welfare of the Eudlo Creek Platypus population, Energex has contracted EcoSmart Ecology to undertake targeted surveys to determine Platypus distribution. As such, this work is aimed at detecting Platypus and providing a habitat assessment; no further assessment of population size, burrow location or potential impacts on the species have been undertaken.

This report provides a brief dossier of the Platypus and its ecology, as well as providing information on the field survey team, survey methodology and survey results.

The primary focus of the study has been to characterise the local population of Platypus, other vertebrates were noted during the work, but were not targeted and are not considered in this report. Vertebrates observed during the surveys are documented in Appendix A.

2.0 PLATYPUS (ORNITHORHYNCHUS ANATINUS) Status: NCA - Special Least Concern; EPBC - Least Concern

Distribution and Habitat: While Platypus can be locally common and are widespread, they are rarely throughout their range which extends along Australia’s east coast from Cooktown in North Queensland, to Victoria and throughout Tasmania (Menkhorst and Knight 2007; Woinarski et al. 2012). Platypus are presumed to have gone extinct in mainland South Australia (Woinarksi et al. 2012).

Platypus inhabit freshwater river systems across a gradient of habitats, altitudes and temperatures from the tropical North Queensland lowlands and into alpine streams of New South Wales (Carrick et al 2008). In addition to inhabiting natural streams and suitable freshwater bodies, they can occur in shallow artificial dams and water storage lakes, particularly where these are in proximity to natural habitats. Waterways which are naturally productive, with a high abundance of invertebrate prey are most likely to support Platypus (Woinarski et al 2012).

Ecology: Platypus are unique amongst mammals worldwide as they are egg laying, aquatic, venomous, and uses mechanoreceptors and electroreceptors (Woinarski et al 2012), traits considered rare in mammals. Prey, which includes a variety of larval and adult aquatic invertebrates (Scheich et al 1986), are not located by sight, but rather using pressure and electroreceptors in their bill, often while it is used to sift and disturb benthic substrata (Carrick et al 2008). Prey is stored in cheek pouches whilst foraging underwater and eaten when floating on the water’s surface.

Although a relatively solitary species, multiple individuals can reside within small water bodies such as dams. Adults can travel at least three kilometres in a single activity period in search of resources (Serena et al. 2001). While most activity occurs in low light conditions, particularly around dusk and dawn, sometimes individuals can be observed foraging throughout the day (Carrick et al 2008). Activity patterns vary depending on day length, locality, water and air temperatures, stream productivity and disturbance (Kolomyjec Pers. Comm).

Platypus construct burrows in steep banks of creeks and rivers, preferring areas with a well-established riparian zone. Burrow entrances are positioned just above the water line and are usually concealed behind vegetation or debris. Breeding females construct a more elaborate burrow that can be up to 30 m long, include earth plugs at intervals, and terminating in a chamber containing a nest of herbage collected from the stream environment and riparian habitats (Carrick et al 2008).

Latitudinal gradients are highly influential on Platypus morphology. Individuals are much larger in the southern portion of their range (Tasmania) and decrease in size the further north (Queensland) they occur. The breeding season starts earlier in northern latitudes (late July-August) and can be over a month later in Tasmania (Carrick et al 2008). Two offspring are usually laid in eggs, hatching after 10 days, young feed by licking milk patches from the abdominal surface of their mother for up to four months (Carrick et al 2008).

SunCoast Power Project Platypus Investigation Energex

Energex Platypus Report_V1.0.docx Page 3

Threats: Platypus rely on healthy productive freshwater systems, with overhanging banks and ample freshwater invertebrates, making them highly susceptible to changes in water quality. Alterations to stream flow, decreases in water quality and ecosystem health can quickly reduce the suitability of streams for Platypus (Woinarski et al 2012). Impacts upstream can cause significant threats to habitat suitability away from the area of impact.

Threats to Platypus are diverse and include construction works, (e.g. dams, weirs and culverts), forestry, mining and industrial activities (land clearing, soil erosion), farming practices (herbicides and pesticides, land clearing, soil erosion, introduced herbivores), pollution (discharge of stormwater and drainage systems), mortality associated with fishing (rope, barbed and non-barbed wire, fishing line, fishing hooks, fishing nets), introduced pests (i.e. foxes and domestic dogs), disease (murcorycosis, Tasmania only) and road mortality (Woinarski et al. 2012).

3.0 STUDY METHODOLOGY

3.1 Desktop Assessment and Background Sources Prior to undertaking field investigations, data sources were reviewed in order to gain an insight into the presence of Platypus within the local area. Previous reports (Energex 2008; GHD 2010) detail survey works done for the SunCoast Power Project, however, these contain little information on Platypus. Available existing information therefore relies heavily on publically available databases (see Table 3.1). Each inspected database has inherent limitations that must be considered during data analysis.

In addition to providing evidence of Platypus occurrence, compiling the databases provides an estimate of recorded frequency for Platypus in the local area. This may later assist in evaluating the likelihood of Platypus occurring within the Project site.

Once compiled the desktop database was plotted using ArcGIS (where coordinates were available) in order to spatially represent known Platypus locations.

3.2 Landholder Liaison Prior to undertaking targeted field works, EcoSmart Ecology used aerial photography and the Digital Cadastral Database (DCDB) to identify properties abutting relevant sections of Eudlo Creek. Often properties on either side of the creek were identified, though in some locations only one adjacent property was considered.

Once selected, landholders were initially contacted by mail, which included a short survey to allow landholders to provide feedback to EcoSmart Ecology about historic, current, or possible Platypus sightings and values within proximity to their properties. Those properties which were identified for further investigation are shown in Figure 3.1.

Closer to the time survey, landholders were contacted by phone to discuss their local Platypus knowledge and to gain permission to access Eudlo Creek through their property. Messages were left

with those landholders initially not available; a process which was repeated on two further occasions after which, if unsuccessful, no further attempt was made. No property was accessed without explicit landholder permission. Access permission was again reaffirmed with most landholders the day prior to survey and many landholders met to discuss Platypus and provide a guided walk around their property. After assessment of the properties, sites were selected for further watching and assessment as outlined in Section 3.3.1.

3.3 Platypus Field Survey Surveys were undertaken under QPWS license WISP06137309 and Animal Ethic License CA 2012/07/624. There are currently no state or federal guidelines for surveying for Platypus, though field survey methods were generally consistent with those used by the Australian Platypus Conservancy and include methods used for Platypus scientific research (Herrin 2009) (see Section 3.3.2). Targeted Platypus surveys were undertaken between 16/09/15-20/09/15, inclusive.

3.3.1 Site Selection Prior to establishing survey sites, background data and data from landholders was collated to provide insights as to where Platypus have previously been recorded. This data was used in conjunction with Google earth imaging and a visual assessment of creek flow, vegetation, and other natural features on individual landholder properties to identify those locations which have the most suitable habitat for Platypus. Most of Eudlo Creek between Lot 3 RP154277 and Maroochydore Road was visually assessed, though some sections downstream of Maroochydore Road and upstream of Chavellum Road were less intensively accessed due to access constraints (see Figure 3.1).

Based on existing information and the above habitat assessment, 12 sites were selected for targeted site-and-wait observation and nine for camera trapping. The location of survey sites and camera traps with respect to Eudlo Creek is provided in Figure 3.2.

3.3.2 Platypus Survey Methods Platypus were sampled using a variety of Platypus survey techniques including observation surveys and remote sensing (camera trapping). All sampling techniques were developed in conjunction with Platypus expert Dr. Stephen Kolomyjec and are generally consistent with recommendations of the Australian Platypus Conservancy.

Sit-and-wait Observation

While the field team took careful observations along Eudlo Creek throughout landholder liaison and inspections for any signs of Platypus activity, targeted sit-and-wait watches were undertaken during the early morning (e.g., 6-10 am) and late afternoon (e.g. 2-6 pm) when Platypus activity peaks (Carrick et al 2008). Twelve sections of stream (Figure 3.2) were watched for a minimum of two hours each, with larger lengths being slowly walked. Pools and deeper sections of water watched for longer periods than less suitable shallow (<~20cm) riffle zones. One section of creekline bordering Lot 2 RP219843 was watched on two occasions (i.e., a total of 4 hrs) as habitat in this area looked promising and there was strong suggestions from landholders that Platypus have been seen in this section of creek.

Each time a Platypus was observed the location (GPS), the number of individuals and notes on behaviour (feeding, basking etc.) was recorded. Photographs of known and potentially suitable habitat were taken.

Remote Sensors Cameras

Remote sensor cameras (Reconyx HC600 and Bushnell Trophy Cams) were experimentally used in this survey. The use of remote cameras for Platypus detection is not common and although detection rates were likely to be very low (Herrin 2009), this method was used in an attempt to improve Platypus detection.

Camera traps were deployed for three nights at seven locations, and two nights at two locations. This resulted in nine sites being camera trapped; a total camera trap effort of twenty-five trap nights. Cameras were focused on sections of stream that appeared highly suitable for Platypus.

3.3.3 Habitat Assessment Habitat assessment along the length of the creek was determined by comparing ecological requirements of Platypus, e.g., steep/undercut banks, sandy soils, overhanging vegetation, aquatic invertebrates (prey), water availability and quality etc. to observed habitat characteristics. Sections of creek were then assigned a relative value (see Table 3.2) based on these perceived characteristics.

A key factor in considering habitat value is the presence of deeper pools with permanent water, which will allow individuals to foraging even during periods of drought. Some caution therefore should be applied to our mapping as the presence of permanent water has been inferred from landholder liaison and the overall appearance of stream characteristics rather than verified stream data. While poor sections of stream may not be permanently inhabitable throughout all conditions, some could be temporarily inhabited or used as movement corridors to larger areas of suitable habitat.

Table 3.2. Eudlo Creek Platypus habitat assessment

Suitability Reason Good Sections dominated by deeper pools with steep undercut banks, overhanging

vegetation and flowing water. Water is known, or likely, to be permanent. These areas are considered likely to be frequented by Platypus.

Average A mix of deeper pools and stretches of shallow water (<0.5m). Some pools of water may be semi-permanent, possibly drying during severe drought. Undercut banks and overhanging vegetation is frequent, though water quality may be murky. Platypus should not be excluded from these areas, though the likelihood that they could occur is lower than in ‘good’ habitat. These sections may not permanently support Platypus through periods of prolonged drought.

Poor Sections with shallow water; widely separated or no deep pools. Water flow is likely to be less frequent, possibly drying on a regular basis. Undercut banks and overhanging vegetation is infrequent. Poor sections are unlikely to permanently support Platypus but may provide access between good and average quality habitat.

Unknown Sections of creek that were not surveyed due to access constraints. Saline Section of creek with a saline influence. Platypus are not known to occur in saline

water.

3.3.4 Survey timing and conditions The Platypus survey was undertaken from the 16/09/15-20/09/15 (inclusive). Conditions during the surveying period were suitable for Platypus detection with calm, cool days and overcast nights. Temperatures ranged from 12.9-28.3°C. A small amount of rain fell during the surveys (10.6 mm), having no noticeable effect on water colour or turbidity. The rainfall is not thought to have impacted on the likelihood of detecting Platypus.

4.0 SURVEY RESULTS: PLATYPUS VALUES

4.1 Platypus Platypus were located at four locations along Eudlo Creek (Table 4.1 and Figure 4.1). While one individual was observed on two separate occasions, once during the day, all observed Platypus was detected during either the morning or evening sit-and-wait observations. None were recorded on the IR cameras. Despite there being average to good habitats upstream (~2.5km) of Bruce Highway, all observations were recorded downstream except one, located approximately 100-150m upstream from the highway. With the exception of one record downstream of Maroochydore Road, all our records coincided with previous documented observations. A description of all Platypus observations and locations is provided in Sections 4.1.1 to 4.1.4 below.

# As illustrated in Figure 4.1

4.1.1 Platypus - 2 RP219843 On the 17th Sept during the morning watch a single Platypus was observed foraging along the banks of a large strait and deep section of creek immediately upstream of the Bruce Highway. The individual was observed foraging over a 30 minute period along a 100m stretch of creek line before disappearing. The Platypus seemed oblivious to the observer, at one time foraging within a distance of little more than 1-2 meters. While the individual was clearly recognisable, it kept mostly to the creek edge where reeds and stream vegetation obscured clear view. This location is consistent with observations documented in Powerline EIS (Energex 2008) as ‘site 21’.

The creek at this location includes a deep, long and comparatively wide body of water and it is possible that individuals spend the majority of their foraging time constrained to this area. Based on the size of this waterbody, we expect water to be permanent. It represents the most upstream confirmed Platypus record during our surveys.

4.1.2 Platypus - 2 RP100852 Initially observed during the day while discussing Platypus values with the landholder, and again observed on the same day (16th Sept) in the same area during the dusk sit-and-wait. During the dusk sit-and-wait the individual was observed moving through a very shallow section of stream between two deeper pools. It is presumed this was the same individual observed earlier in the day. Platypus have been previously noted from this property at this location.

The section of creek line where the Platypus was observed includes a series of sharp ‘switchbacks’ where the scouring process of water has created deeper pools. These pools are separated by short stretches of shallow (<~0.4m) riffles. Individuals are likely to move between these pools (as observed) frequently while foraging. Based on landholder discussion most of these deeper pools are likely to be permanent.

4.1.3 Platypus - 5 SP16983/2 RP70991 Briefly observed on the 16th Sept during the afternoon sit-and-wait; after an observation the individual quickly disappeared from view and was no longer seen. Local landholders indicate that Platypus are regularly observed here, and Platypus video from this area has been posted to the internet. The presence of Platypus at this location has been documented within Powerline Project EIS (Energex 2008) as sites ‘23’ and ‘25’.

At this location on Eudlo Creek the stream includes a number of ‘switchbacks’ with deeper pools, abundant fallen logs, undercut banks and good riparian habitat. Larger pools of water separated by short shallow sections are located upstream and downstream of the observation. Discussion with the local landholders indicates that water is largely permanent in these deeper pools. Individuals are likely to move through shallower sections to the larger pools for foraging.

4.1.4 Platypus – Old Maroochydore Road Following a tip from a local landholder, creek line running through council reserve outside our main area of interest was accessed from the old Maroochydore Road corridor on the 19th Sept. Here one individual was observed during the evening sit-and-wait as it swam upstream, climbing over fallen logs on the way, before foraging in a large pool of water on a sharp bend.

To our knowledge Platypus have not been directly recorded in this section of Eudlo Creek, though habitat here is perhaps amongst the best encountered with many close or interconnected deep pools, undercut banks, abundant fallen trees, and clear flowing water. The Riparian vegetation in this area was also in very good condition. We would expect that more Platypus would be located along this section of creek with further survey effort.

4.2 Platypus Habitats The suitability of Eudlo Creek for Platypus varies along its length, but generally improves downstream along its gradient (Figure 4.1). Unfortunately a number of landholders were either uncontactable, or did not allow access to properties upstream of Chavellum Road. However we were able to inspect stream condition and characteristics at a number of locations, including where it crossed public roads. These inspections, coupled with aerial photography, suggests that the upper stretches of Eudlo Creek is, on balance, narrow, dominated by shallow riffle zones, lacks overhanging banks and vegetation, and is most likely to dry during prolonged drought. The landholder of Lot 3 RP 154277 noted that on his property the stream has become heavily silted leading to a reduction in the number of deep pools, and is more likely to dry during drought. These factors suggest that it is unlikely that Platypus are resident upstream of Chavellum Road.

A notable increase in the frequency of deep pools and therefore habitat value, occurs around the Chavellum Road Crossing. This change is marked by a large deeper section of stream on the west branch of Eudlo Creek which extends upstream from the Chevallum Road for a short distance (starting near Lot 1, RP213261), but some considerable distance downstream (>100m). Some landholders have indicated that Platypus were historically known from this pool (c.a. early 1990’s), but are unware of recent observations. We also failed to locate any Platypus in this pool.

Our surveys located only one Platypus in the section of Eudlo creek between the Bruce Highway and Chavellum Road - in a large pool to the immediate west of the Bruce Highway (near Lot 18, RP845421). However sections of both average and good habitat occur along this section of the catchment. Landholders from Lot 2 RP219843 report recent Platypus sightings a further ~500m upstream of our observations. If necessary for planning or conservation purposes, further work would be required between the Chavellum Road crossing and the Bruce Highway to confirm and characterise

Energex Platypus Report_V1.0.docx Page 12

the extent of Platypus in this section of the catchment as one-off surveys can overlook shy taxa (Eyre et al 2014).

Long sections of Platypus habitat extend downstream of the Bruce Highway to Eudlo Flats Road, particularly downstream of Maroochydore Road. We would expect Platypus to be present throughout this section of the catchment.

The value of habitats further downstream of Eudlo Flats road is unclear as we did not seek property access due to its deviation from Energex’s area of interest. Aerial photography and on-ground inspection off Eudlo Flats road suggest the creek alignment may have been altered. This may not necessarily exclude Platypus if deep pools suitable for foraging are present, however at some point Platypus will no long occur due to saline intrusion.

5.0 SUMMARY AND CONCLUSIONS Our work has confirmed previous reports of Platypus within Eudlo Creek. Four Platypus were observed, all located in close proximity to (~300m upstream) or downstream of the Bruce Highway.

Habitat assessment and these records suggest that values for Platypus along Eudlo Creek could be broadly segregated into three sections:

• Upstream of Chavellum crossing where Platypus values are, on balance, low and there is little confirmed or anecdotal evidence of Platypus records. It seems unlikely that Platypus will be resident through this section of the catchment.

• Between Chavellum Road and Lot 18 RP 845421 (~300m upstream of the Bruce Highway). We failed to locate Platypus along this section of stream, and none were noted in previous studies (e.g., Energex 2008). However recent landholder observations suggest some individuals may be present. While there are deep pools, these are separated by shallow water and it remains unclear if there is sufficient habitat during drought to support the species. Anecdotal evidence suggests Platypus were once present along the upper reaches of this section, but may have declined in recent decades. If understanding of the species distribution is required, this section of stream should be the main area of focus.

• Downstream of Lot 18 RP 845421 where there are numerous confirmed and well documented Platypus sightings. Historic records of Platypus and the likelihood that permanent water is present even during drought suggest this section of the catchment supports a permanent Platypus population.
