Explanatory Statement This Guideline is comprised of three sections— Section 1 outlines and discusses each of the five The purpose of the Koala Safety Fencing and Measures (5) requirements for KSFM and provides Guideline (the Guideline) is to provide direction and solutions for each requirement; supporting information on Koala Safety Fencing and Measures (KSFM) applicable to development in the Section 2 identifies which solutions for each KSFM South East Queensland Koala Protection Area (SEQKPA) requirement that would be applicable to and to assist development to meet the Development different development types; and Assessment Code requirements of the draft South East Queensland Koala Conservation State Planning Section 3 provides general koala information to assist Regulatory Provisions (December 2009). with consideration of alternative solutions KSFM is based on koala sensitive design principles.

The Development Assessment Code at Annexe 2, Schedule 3 of the draft South East Queensland Koala Conservation State Planning Regulatory Provisions (December 2009) specifically facilitates the aim of retaining and protecting koala habitat values in their natural state to maximise and provide koalas with feeding, resting and movement opportunities (for example, through its requirements relating to habitat retention and vegetation clearing). The measures outlined in this Guideline address the permeability and threat reduction aims only. This Guideline is to be used to assist development meet the requirements of the KSFM Probable Solutions as required by the Development Assessment Code for the draft South East Queensland Koala Conservation State Planning Regulatory Provisions (December 2009). It may also provide guidance to development occurring in other areas with koala populations and koala habitat values. The Development Assessment Code also includes requirements which may be broadly considered part of ensuring development design and delivery does not impact on koalas, such as sequential clearing practices. These requirements are not repeated in this Guideline. Koala Safety Fencing and Measures Guideline 3
1. Koala Safety Fencing and In all instances options for each KSFM requirement identified as applicable to the development type must Measures requirements be fully met in order to achieve compliance with the Guideline. However, where applicable, combinations of Koala mortality can be a direct result of human-induced options should be considered to maximise the inclusion threats arising as a consequence of urbanisation and of KSFM design, thereby achieving best practice by development. Development results in initial impacts mitigating the impact of development on koalas to the to koalas associated with the clearing of koala habitat greatest extent possible. and longer term impacts as a result of the introduction of threats (such as roads, cars and dogs) once the These requirements are outlined in Table 1 Solutions to development is established.

Koala friendly fencing can be used to allow koala movement between areas of habitat and can be erected within properties or on site/lot boundaries. 5. Roads – Road mortality is one of the major causes of death or serious injury of koalas when roads bisect koala habitat. This requirement is about the placement and design of roads to allow koalas to safely traverse the landscape. 6. Pools – The drowning of koalas in pools is avoided or reduced by incorporating features to allow koalas to easily exit the pool or by preventing access to the pool. 7. Dogs – Domestic dog attacks on koalas result in serious injury or death to koalas and is one of the major threats to koalas in the urban area. This requirement provides measures to limit dog and koala interactions. 8. Community Engagement – Education and cooperation of the public is required to achieve koala conservation outcomes. 4 Koala Safety Fencing and Measures Guideline

Additions to a means for koalas to climb over fences, Fencing Option D retaining walls or other structures. Leave vegetation on either side of the fence with canopies or trunks extending beyond the height of the fence and where canopies are connected or tree trunks are less than 1m apart. (Fig. 6). Option E Install a timber post or log (of at least 125 mm in width or diameter) leaning against the top of the fence but positioned at an angle to the fence so that the log is not flush with the fence (i.e. the space between the base of the log and the bottom of the fence is at least 400 mm. (Fig. 7). Option F Install ladders of the following dimensions and design: (1) Ladder rungs are timber and at least 300 mm in width, 50 – 100 mm in height and a minimum of 20 mm in depth to provide grip for koalas (Fig. 8); and (2) Rungs are spaced horizontally with a 150 – 400 mm gap between rungs for ease of climbing; and (3) Attachment material is webbed or latticed to provide additional footholds for koalas. Option G Install a simple koala bridge (particularly suited to security fences) (Fig. 9) using timber logs of at least 125 mm in diameter of the following design: (1) Timber logs are positioned adjacent to and within 1 m of each other on either side of the fence and extend for at least 1m above the fence; or (2) A cross piece of similar diameter to the logs connects the two vertical timber posts that are within 1 – 4 m of each other on either side of the fence . Additional requirements for Options C to G The frequency of these measures used to allow koalas to manoeuvre over unfriendly fencing are provided: (1) At least once in a backyard to allow animals to exit a property; or (2) At least once every 50 m where the length of the impassable barrier/fencing is greater than 200 m.

Koalas in Queensland using the most direct route. These can be , through average 4 – 8 kg in weight. backyards (Fig. 28) and across roads (Fig. 29). • Adult koalas are of the following general dimensions: • Koala habitat includes any vegetation that koalas Height walking – average 30 cm ; Reach when use in their day to day activities and is not limited standing on back legs – maximum for large adult to eucalypt or related species of tree, particularly 90 cm. in urban environments. ‘Habitat’ therefore includes • Koalas can jump to the ground from over 2 m, but other native (or exotic) vegetation that occurs in prefer to descend right to the base of the tree when association with the eucalypts needed as a food coming down to the ground. resource. Koala habitat may also include cleared • Koalas can leap from the ground to around 1.2 m onto areas that koala use to move between vegetated a tree or other structure. patches. • Koalas prefer to travel across a road in the most direct route unless forced to use an underpass or overpass via koala exclusion fencing. Koalas will not climb across flexible material that bends under their weight, such as rope bridges. • When faced with an obstacle (such as fencing), koalas will try to go under it or through , taking the path of least resistance/effort before attempting to climb over the obstacle. • Koalas can swim, but their fur soon becomes waterlogged and they often drown if left in the water for any time. Swimming pools with a lip do not allow koalas easy access out of the water and they often swim back and forth around the edge of the pool looking for an exit. • Koala breeding season is from August to December which includes the lead up to mating and the few months when the majority of mating occurs. In the lead up to mating there is often jostling and fighting for dominance among the resident male koalas. These social pressures are potentially one of the triggers for the dispersal of young sub adult animals entering their first breeding season. Koala Safety Fencing and Measures Guideline 13

Glossary Words used in this Guideline have the same meaning as in the draft South East Queensland Koala Conservation State Planning Regulatory Provisions (Dec 2009). Particular words used in this Guideline are defined below. Supplementary koala habitat tree means a tree that usually comprises the mid storey forest layer and includes species such as Casuarina, Acacia, Banksia and riparian tree species that occur in association with koala habitat trees to provide shelter or resting opportunities for koalas. Koala furniture are structures that are placed within or used in association with road crossing structures that increase the ability of koalas to successfully move through an area, for example, horizontal logs placed within a culvert may enhance the use of the structure by koalas. ‘Go Slow’ Point is an area where koalas are known or anticipated to cross a road and where features have been incorporated to reduce vehicle speed.
