“…Modelling has been conducted on pooled road-kill data (e.g. Ramp et al 2005), but this often fails to consider species differences in habitat preferences, behavioural responses to roads and general ecology of the various species recorded. By conducting species-specific road-kill modelling, more accurate predictions and conclusions can be drawn.…”

Abstract. Understanding the impacts of roads on wildlife and the natural environment is of increasing importance. Macropods (mostly kangaroos and wallabies) are a diverse and widespread taxon in Australia that has been significantly affected by the presence of roads in various ways. We reviewed the available literature on macropods and roads, assessing 60 scientific journal articles, reports and theses. Studies on road mortalities were the most prevalent (n = 29, with 12 on macropods only), revealing both spatial and temporal patterns in occurrence. Behavioural studies in relation to the road environment are limited (n = 2) yet could help our understanding of patterns of road-kill and other impacts. Some macropod populations are critically affected by the presence of roads (e.g. brush-tailed rock-wallaby, Petrogale penicillata) due to either proportionately high road mortalities and/or population fragmentation, and may face continued decline unless effective road-mitigation measures are implemented. Investigations of various types of road mitigation focussed on wildlife-exclusion fencing and road crossing structures as the most effective option, although the high cost of these measures appears to limit their implementation. Further research into several areas was identified, particularly on species where severe road impacts are likely to result in population declines.

“…) Geoprocessing and data analysis For each animal, elevation and northness were computed using the exact coordinates recorded at sampling location with a 100-m grid cell resolution. Since one-point location may not be representative of the environment in which the animals live and could be subject to bias due to sampling method, average altitude and northness were additionally assessed for the circular sampling area (CSA, i.e., surface around the sampling location) of each individual, as proposed by Ramp et al (2005). Size of CSA was derived using home-range sizes from studies conducted in similar habitats (Hardenberg et al 2000;Meile et al 2003;Boschi and Grignolio et al 2004;Baumann 2005;Nesti et al 2010).…”

“…There is a large amount of evidence that roads, and more specifically vehicles, are a mortality risk for many species of wildlife (e.g., Groot Bruinderink and Hazebroek 1996, Lodé 2000, Clevenger et al 2003, Ramp et al 2005, Lovari et al 2007). The research linking road effects with consequences at the population level has identified a reduction in demographic rates (Foppen and Reijnen 1994, Mumme et al 2000, Row et al 2007, an increased risk of extinction (Gibbs and Shriver 2005), and a reduction in population densities or abundance (Fahrig et al 1995, Marsh and Beckman 2004, Fahrig and Rytwinski 2009.…”

ABSTRACT. Roads and traffic are prominent components of most landscapes throughout the world, and their negative effects on the natural environment can extend for hundreds or thousands of meters beyond the road. These effects include mortality of wildlife due to collisions with vehicles, pollution of soil and air, modification of wildlife behavior in response to noise, creation of barriers to wildlife movement, and establishment of dispersal conduits for some plant and animal species. In southeast Australia, much of the remaining habitat for the squirrel glider, Petaurus norfolcensis, is located in narrow strips of Eucalyptus woodland that is adjacent to roads and streams, as well as in small patches of woodland vegetation that is farther from roads. We evaluated the effect of traffic volume on squirrel gliders by estimating apparent annual survival rates of adults along the Hume Freeway and nearby low-traffic-volume roads. We surveyed populations of squirrel gliders by trapping them over 2.5 years, and combined these data with prior information on apparent survival rates in populations located away from freeways to model the ratio of apparent annual survival rates in both site types. The apparent annual survival rate of adult squirrel gliders living along the Hume Freeway was estimated to be approximately 60% lower than for squirrel gliders living near local roads. The cause of the reduced apparent survival rate may be due to higher rates of mortality and/or higher emigration rates adjacent to the Hume Freeway compared with populations near smaller country roads. Management options for population persistence will be influenced by which of these factors is the primary cause of a reduced apparent survival rate.
