1 Introduction

Eco Logical Australia Pty Ltd (ELA) was commissioned by Conservation Planning and Research, ACT Government (CPR), to undertake targeted surveys for Delma impar (Striped Legless Lizard) centred at three Gungahlin Grassland Reserves (Crace, Gungaderra and Mulanggari) in the Australian Capital Territory (ACT). Surveys were undertaken over a ten week period between October and December 2012.

1.1 STUDY AREA The study area comprises three Grassland Reserves (Crace, Mulanggari and Gungaderra) and adjoining associated open space in Gungahlin, in the north of the ACT (Figure 1). The grassland reserves are regarded as nationally significant and contain approximately 170 hectares (ha) of intact lowland temperate native grasslands. They are comprised primarily of Themeda triandra (Kangaroo Grass), Poa spp. (Tussock Grass), Rytidosperma spp. (Wallaby Grass), and Austrostipa spp. (Spear Grass). Surrounding the intact grasslands and providing a buffer to these core areas are approximately 330 ha of disturbed grasslands.

1.2 STUDY AIMS The aim of the Striped Legless Lizard (SLL) surveys is to provide information on the distribution and density of SLL in the Crace, Mulanggari and Gungaderra Grassland Nature Reserves and adjoining open space. The surveys will be used to compliment the Kangaroo grazing monitoring within Mulangarri and Crace being conducted by CPR, along with providing opportunistic sightings for all reserves of other threatened grassland species, including Synemon plana (Golden Sun Moth) and Perunga ochracea (Perunga Grasshopper).

The key components of the study are to:

 Determine the presence or absence of the species across the three grassland reserves using an artificial shelter survey method, and where present, provide an estimate of the population abundance and/or density

 Gauge the distribution of the species across the three grassland reserves

 Provide a report that details:

o The methodology used o GPS location of all grids (map grid of Australia) o Survey results and interpretation for each survey area including: . total number of captures and dates of captures

. number of unique individuals captured

. the number of recaptured individuals . an estimate of the minimum population size and population density using a conservative buffer to account for the movement of individuals around available habitat and extrapolation of the number of captures per grid

o records of all vertebrate species observed under tiles and records of opportunistic observations of other threatened grassland species

1.3 STRIPED LEGLESS LIZARD BACKGROUND The SLL is a grassland dependent species of temperate Australia reaching up to 30 centimetres (cm). The characteristic trait of this family is the lack of fore-limbs and the reduction of the hind-limbs to vestigial flaps (SEWPAC, 2011a). The species is tan in colour and can be characterised by the presence of stripes running horizontally along the length of the body, however, this trait can be faint or entirely absent (SEWPAC, 2011a).

The species has a patchy distribution in grasslands of south-eastern New South Wales, The Australian Capital Territory, north-eastern, central and south-western Victoria, and south-eastern South Australia (SEWPAC, 2011c). The distribution of this species within the ACT is fragmented, with populations occurring in four disjunct regions, of which one is Gungahlin (Grassland Reserves) (ACT Government, 1997).

The species primarily occurs in Lowland Grassland vegetation types dominated by perennial tussock- forming grasses such as Austrostipa spp., Themeda triandra or Rytidosperma spp. The species is known to show preference for ecosystems with a-greater-than 70% cover of Themeda triandra and a deep thatch between the grass sward (Osborne et al., 1993). Little is known about the species' habitat use, although it is theorised that they over-winter at the base of tussock-forming grasses (ACT Government, 1997). The species has been shown to move about the available habitat with individuals recorded moving up to 20 metres (m) in one day and up to 50m over a period of several weeks (SEWPAC, 2011a).

2 Methodology

ELA and ACT Government staff undertook targeted surveys for the SLL during the October to December period of 2012. The surveys used an artificial shelter (roof tiles) method with two different grid formations to determine the presence of the species across the three grassland reserve areas. Artificial shelter survey locations in Crace and Mulanggari were guided by Kangaroo monitoring plots established by CPR.

2.1 ARTIFICIAL SHELTER SURVEYS Targeted surveys were undertaken using an artificial shelter survey method, consistent with the ACT survey guidelines Survey Guidelines for the Striped Legless Lizard (ACT Government, 2011) and the Survey Guidelines for Australia’s Threatened Reptiles developed by the Commonwealth (SEWPAC, 2011b).

Artificial shelters were set across the three grassland reserves using two different grid formations described below.

 Grid A: Consisted of 30 tiles in three rows of ten tiles (0.45 ha area). The rows were 25m apart and the tiles 10m apart. In Crace and Mulanggari, Grid A was located at each of the 1 ha kangaroo grazing monitoring plots established by CPR. These sites were stratified by tree cover and a stratified random design was used to determine the location of the monitoring plots. Random number generation was used to locate all Grid A locations in Gungaderra.  Grid B: Consisted of 50 tiles in five rows of ten tiles (0.09 ha area). The rows and tiles were 5m apart. Grid B was offset from Grid A by 50m at each location.

All rows were aligned along a north south compass bearing.

Crace and Mulanggari Grassland Nature Reserve areas: Grid A was established at eight locations within each of the one hectare (ha) Kangaroo grazing long-term monitoring plots at Crace and Mulanggari. Grid B (and offset by 50m) was established at five of these locations with each reserve. The variation of the vegetation present was considered in choosing the locations for Grid B. A total of 980 tiles (490 over 13 grids per reserve) were laid within Crace and Mulanggari.

Gungaderra Grassland Nature Reserve area: Grid A and Grid B (offset by 50m) were established at six locations within Gungaderra. The locations for Grid A were randomly pre-selected by CPR and the locations for Grid B were chosen with consideration of the variation of the vegetation adjacent to Grid A. A total of 480 tiles over 12 grids were laid within Gungaderra.

At Crace and Mulanggari the survey tiles were aligned with the long term kangaroo grazing plots to provide data for the SLL survey and to monitor reptiles for the kangaroo grazing research. One of the aims of the kangaroo grazing research is to quantify the effect of kangaroo grazing on the abundance and diversity of small ground frequenting animals, such as reptiles. It is anticipated that the reptile survey results will be used to inform land managers of the optimal kangaroo densities that are likely to provide the most favourable habitat conditions for small reptiles, including the SLL. As part of the grazing research, further roof tile arrays have been placed and surveyed in grassland and woodland reserves across northern ACT and Googong.

Striped Legless Lizard Surveys 2012: Gungahlin Grassland Nature Reserve areas

All tiles in the Gungahlin survey were laid on the 2-4th October at least two weeks prior to the first check. Upon placement, all grid locations were marked with a GPS and each tile was individually numbered using spray paint, so as to be independently identifiable. Numbers were accorded to each row, thus numbers in the same ten cohort (e.g. 23, 24, 27) are in the same row and those numbers that share a common last digit are in the same column (e.g. 23, 33, 43). Each tile in the Grid B progression is 5m apart, while those in Grid A are 10m or 25m to their nearest neighbour. The locations of the grids were mapped and are included in Figure 2.

All tiles within each grid were checked once a week for a total of ten weeks (ten checks) with the first check conducted over the 18th & 19th October. ELA and staff from the Environment and Sustainable Development and Territory and Municipal Services directorates shared the checking duties with each undertaking five checks. The weekly checks (surveys) were conducted in the mornings and involved the turning of each tile to inspect for any fauna activity underneath. Any fauna observed was identified along with the grid location, tile number and date.

Where an individual SLL was captured, the following data was recorded onto a data sheet:

 Grid location and grid type  Tile number  The length of the lizard (snout to vent and total length). In an effort to reduce stress on lizards and possible resultant shedding of tail sections, lizards were not always totally prised into a unfurled length, so measurements were in some cases, part estimates accurate to a few centimetres.  Any other notable features (scars, pattern of stripes etc.)  Photo numbers. Macro-photography was used to take images of the scales on the head of the reptile to aid in re-capture identification (Figure 3). Images were also taken of the lateral surfaces of the head.

On a few occasions more than one striped legless lizard was under the one tile, and only one of the lizards could be captured, or particularly in the warmer part of the day some lizards avoided capture. The location of lizards that could not be measured, but which were observed sufficiently to identify were recorded.

The occurrence of shed skins under tiles was also recorded.

Opportunistic observations of other threatened grassland fauna, including Golden Sun Moth and Perunga Grasshopper were also recorded.

All data sheets were entered into an electronic spread sheet for analysis and interpretation. ELA collated all of the photographs and field data from the surveys for recapture identification and population abundance estimates.

A density calculation was undertaken to describe the density of the species within each Grassland Reserve. The calculations attempt to account for the movement of individuals around available habitat by incorporating a buffer zone to the grid areas (Grid B (0.09 ha) & Grid A (0.45 ha)) and extrapolation of the number of captures per grid. Two buffer zones were used in the density calculations for each grid; no buffer and a 20m buffer. A conservative 20m buffer was used to account for the potential movement and overlapping territories of the SLL within the study area.

3 Results

The SLL surveys undertaken by ELA and ACT Government staff during October - December in 2012 recorded individuals as occurring at most of the locations across three Grassland Nature Reserves. The results of the surveys are presented below. Details of each individual SLL captured are presented in Appendix A and opportunistic observations are presented in Appendix B.

The location of the SLL individuals recorded during the surveys across the three Grassland Reserves and adjoining open space have been mapped and presented in Figures 4-6.

3.1 STRIPED LEGLESS LIZARD CAPTU RES

3.1.1 Crace Grassland Nature Reserve Area There were a total of 60 SLL identified from 84 captures within Crace (Table 1). A total of 490 tiles were checked over the ten survey weeks, representing a capture success rate (using total captures) of approximately 1.7%. Density calculations (individuals per hectare) varied considerably, ranging from 0.85 (SLL/ha) for Grid 5A to 155 (SLL/ha) for Grid 7B. All grids except Grid 6A recorded at least one SLL. Grid 6A was set within a woodland vegetation community with a limited grassy understorey.

3.1.2 Mulanggari Grassland Nature Reserve Area There were a total of 90 SLL identified from 110 captures within Mulanggari (Table 2). A total of 490 tiles were checked ten times each, representing a capture success rate (using total captures) of approximately 2.2%. Density calculations (individuals per hectare) varied considerably, ranging from 0.85 (SLL/ha) for Grid 1A to 133 (SLL/ha) for Grid 3B. All grids except Grids 4A and 2A recorded at

Striped Legless Lizard Surveys 2012: Gungahlin Grassland Nature Reserve areas

least one SLL. Grids 2A and 4A were set primarily within exotic pasture dominated by Phalaris aquatic (Phalaris). Isolated paddock trees were also recorded at the southern end of Grid 4A. In contrast, high SLL numbers were recorded in neighbouring grassland, to 2A, of similar habitat condition in 2011 (Biosis Research 2012).

3.1.3 Gungaderra Grassland Nature Reserve Area There were a total of 101 SLL identified from 129 captures within Gungaderra (Table 3). A total of 480 tiles were checked ten times each, representing a capture success rate of approximately 2.7%. Density calculations (individuals per hectare) varied considerably, ranging from 5.1 (SLL/ha) for Grid 2A to 177 (SLL/ha) for Grid 3B. All grids except Grid 2B recorded at least one individual SLL. Grid 2B occurred on a hilltop dominated by native grasses and forbs, with occasional loose surface rocks.

* SLL (G52) was observed at both Grid 4A & 4B. The total number of captures at Gungaderra has been adjusted accordingly.

3.2 DISTANCE TRAVELLED BY SLL Across the three reserves, SLL were re-caught on 71 occasions. Of these 54 recaptures (76%) were under the same tile, a further 6 (8.5%) of recaptures were under an adjacent tile 5m away (Table 4). Only 6 (8.5%) of recaptures were further than 10m apart. There was only one record of movement greater than 20m and that was of lizard G52 (pictured in Figure 3), which travelled 80m in two weeks in November between tiles in Grid 4A and Grid 4B. The average distance between recaptures was 3.4m, but a third of all movement was undertaken by one lizard.

3.3 STRIPED LEGLESS LIZARD NON-CAPTURES Lizards were observed but not captured, measured or photographed on 19 occasions within Crace, 20 occasions within Gungaderra and 18 occasions in Mulanggari. In addition shed skins were recorded under 18 tiles from which no live striped legless lizard was observed. Table 5 indicates the distance that a skin or non- captured individual was from a measured individual.

Table 5: Non-captured SLL

DISTANCE TO NEAREST RECORDED LIZARD (M) 0 5 10 15 20 >25

Shed Skin  Crace 3 2 6 - 1 2  Gungaderra 4 5 1 - - -  Mulanggari 2 0 1 - - -

Lizard not caught  Crace 3 2 8 - 2 4  Gungaderra 7 7 2 2 - -  Mulanggari 6 1 6 1 1 1

If it is assumed that a shed skin or a non-caught lizard 10m or further from the location of a recorded lizard is a new individual then 23 captures would be added to the Crace tiles, five captures would be added to those of Gungaderra and 11 captures to those of Mulanggari.

3.4 STRIPED LEGLESS LIZARD DENSITY AND ABUNDAN CE A minimum estimate of the density and abundance of SLL across each of the three reserves and adjoining open space can be made by assuming that all lizards present within a grid were observed under a tile. Given that of the 251 individual lizards captured only 71 (29%) were recaptured the assumption is likely to be conservative and underestimate the actual density.

The density and estimated abundance of SLL will differ according to whether data from shed skins and non-captures is included and by the size of the buffer area placed around a grid to incorporate those lizards that may move into a grid from the surrounding area. Based on previous trapping results buffer

Striped Legless Lizard Surveys 2012: Gungahlin Grassland Nature Reserve areas

areas of 10m (Williams et al 1995) or 20m (Biosis Research 2012) have been utilised. The results of this study where 84.5% of all recaptures were within 5m of the initial capture, indicates that a 10m buffer is likely to be sufficient.

The relatively small average movement of SLL also suggests that the design for the kangaroo grazing tile (Grid type A) is unlikely to capture all lizards within a grid as distance to a nearest tile maybe be up to 5m in one direction and 12.5m in another. This probably explains why density estimates from Grid A arrays is much less than that estimated from Grid B arrays.

Gungaderra 37.8 240 59 9072 65 41.67 9984 (6 arrays) 2

It is clear that all grassland reserves support large populations of SLL. There are at least in the order of 1000 – 3000 individuals at Crace, 2000-4000 individuals at Mulanggari and 3000 -9000 individuals at Gungaderra.

It is highly likely that multiple observations were made of individual animals. A table detailing opportunistic observations of fauna recorded under the tiles within the three Grassland Nature Reserves is included in Appendix B.

SLL was the most numerous vertebrate recorded under the roof tiles across all three reserves.

Six Golden Sun Moths were also recorded from three locations within Crace and two from Gungaderra on the 18th December during check 10. The individuals were observed flying at Grid 1A, Grid 7B and to the south-east of the model aircraft landing strip within Crace and at Grid 5A in the north-western section of Gungaderra.

4 Summary

Eco Logical Australia and ACT Government staff undertook targeted surveys (using artificial shelters) for Delma impar (Striped Legless Lizard) across and adjoining three grassland nature reserves at Crace, Mulanggari and Gungaderra, over ten weeks between October and December 2012. The aim of the surveys was to provide information on the occurrence and density of SLL in the three Grassland Reserve areas.

Artificial shelters were set across the three grassland reserves using two different grid formations:

 Grid A: Consisted of 30 tiles in three rows of ten tiles (0.45 ha area 0.77 ha catchment area). The rows were 25m apart and the tiles 10m apart  Grid B: Consisted of 50 tiles in five rows of ten tiles (0.09 ha area 0.26 ha catchment area). The rows and tiles were 5m apart. Grid B was offset from Grid A by 50m at each location

Crace and Mulanggari each contained eight Grid A and five Grid B formations. The Grid A formations at these two Grassland Reserves were set within the one hectare Kangaroo grazing monitoring sites. Gungaderra contained six Grid A and six Grid B formations.

A total of 251 individual SLL were identified from 323 captures from the three Grassland Reserves (Table 4). Gungaderra recorded the highest number of captures with the highest density recorded at a single grid also observed at Gungaderra. All grids recorded at least one SLL capture except Grid 6A at Crace, Grid 4A at Mulangarri and Grid 2B at Gungaderra.

Table 8: Summary for SLL targeted surveys TOTAL TOTAL CAPTURE NUMBER OF POPULATION GRASSLAND SLL CAPTURES RATE TILES ESTIMATE

Crace 60 84 1.7% 4900 1000-3000

Mulanggari 90 110 2.2% 4900 2000-4000

Gungaderra 101 129 2.7% 4800 3000-9000

All reserves support abundant populations of striped legless lizard and this lizard is the most abundant vertebrate within the reserves.

There were 71 recaptures and most of these were under the same tile, with 84.5% of recaptures being within 5m of the original capture location. One lizard moved 80m, while only 6 recaptures were further than 10m distance, suggesting that a 10m buffer around tile arrays is probably a reasonable indication of the area from which lizards may have been drawn to a tile.
