On the contrary, a common response to reptiles is a desire to have them removed, with licensed handlers able to generate some income from relocat- ing them (Shine and Koenig 2001). In Australia, a number of front-fanged venomous snakes (family Elapidae) and goannas (family Varanidae) have per- sisted in frequently-used areas (Butler et al. 2005; Shea 2010). The Elizabeth Macarthur Agricultural Institute (EMAI), situ- ated in Menangle, New South Wales, is an example of a well- Fig. 1.

The landscape is a mosaic of open woodland rem- nants and livestock paddocks on gently undulating terrain situated between the Nepean River and the Razor Back Range (Starr et al. 2004; Mo 2017, 2018). Large permanent dams have been established to provide water in addition to ephem- eral floodplains. Vegetation restoration has been progressively implemented to create conservation corridors throughout the property. The institute buildings occupy 11 ha of the EMAI property and are situated south of a large permanent dam. The juxtapositioning of the institute buildings and agricultural land had led to staff encounters with wildlife, which has raised health and safety concerns. European Rabbit (Oryctolagus cuniculus) warrens are common on the property, particularly Fig. 2. A Red-bellied Black Snake (Pseudechis porphyriacus) descending into in the immediate vicinity of buildings (Fig. 2). These warrens a rabbit warren. provide retreat sites for other species, including reptiles. I collected data on snake and goanna sightings within the site. Sightings were primarily gathered by reports from 100 m of institute buildings at EMAI between February 2014 institute staff, either reported to reception or me directly. and February 2017, during the time when I had an office at Reporting wildlife sightings to the institute reception had Table 1.

These reported sightings tended to be biased toward animals found directly outside institute buildings and potentially hazardous species, such as
