“…Likewise, the effectiveness of road signs increases with amongst others its universality (i.e., using one shape, one set of colors and one, generalized animal depiction: much of this is coded by the 1968 Vienna Convention on Road Signs and Signals), local adaptations (for instance, background color to reduce glare), and the type of animal that is featured on the sign [103]. During our research, we came across a good number of local, well recognized, and charismatic primates that feature on road warning signs, including macaques in Japan, Indonesia and Gibraltar, langurs in Sri Lanka, baboons in South Africa, gibbons in India, and howlers in Colombia.…”

As road infrastructure networks rapidly expand globally, especially in the tropics, previously continuous habitats are being fragmented, resulting in more frequent wildlife–vehicle collisions (WVC). Primates are widespread throughout many sub-/tropical countries, and as their habitats are fragmented, they are increasingly at risk of WVC. We created the Global Primate Roadkill Database (GPRD), the largest available standardized database of primate roadkill incidents. We obtained data from published papers, un-published and citizen science databases, anecdotal reports, news reports, and social media posts. Here, we describe the collection methods for the GPRD and present the most up-to-date version of the database in full. For each primate roadkill incident, we recorded the species killed, the exact location, and the year and month the roadkill was observed. At the time of publication, the GPRD includes 2862 individual primate roadkill records from 41 countries. As primates range in more than twice as many countries, the absence of data from these countries is not necessarily indicative of a lack of primate vehicular collisions. Given the value of these data for addressing both local and global research questions, we encourage conservationists and citizen scientists to contribute to the GPRD so that, together, we can better understand the impact road infrastructure has on primates and evaluate measures which may help mitigate risk-prone areas or species.

“…Reducing AVC frequency and severity by mitigation measures is crucial both for the wildlife conservation and for the traffic safety (Coffin, 2007;Tryjanowski et al, 2021). For road managers, deciding on what mitigation method to use is often challenging.…”

“…Landscape ecological analyses are used for predicting AVC hotspots based on the landscape composition, and the traits and movements of animals (Valerio et al, 2023). The place for warning signs is usually chosen this way (Tryjanowski et al, 2021). However, for a comprehensive understanding of factors influencing AVC it is also essential to explore the human factor, that is, the habits and attitude of drivers.…”

“…There is also concern that ever-increasing road construction and vehicle numbers may cause local extinctions: even 20 years ago "an estimated 15-20% of the United States is ecologically impacted by roads" (Forman & Alexander 1998), and a recent review found rare primates were also at risk (Hetman et al 2019). In view of proposals to eliminate all mammalian pests from New Zealand by 2050 (Russell et al 2015), the introduction of silent, or driverless electric vehicles (Tryjanowski et al 2021), and the growth of "citizen science" as a monitoring tool (Olson et al 2014, Vercayie & Herremans 2015, historical records may become of interest as a base-line for future ecological comparisons; and the 2016-18 counts provide a reasonably robust view of the present status throughout New Zealand. The adoption of a standard international protocol, as recommended by Collinson et al (2014), seems premature; the aims and faunal diversity differ too widely between countries.…”

Road-kills were recorded at random throughout New Zealand, on 96359 km of roads, avoiding towns and busy motorways, from 1963-2018. Traffic increase from 1.04 m to 4.33 million vehicles during the study had little effect on mortality, even at the greater traffic density in the North Island. Seasonal changes measured on 8435 km (151 trips) between Lower Hutt and Otaki from 1985-2015 showed lowest mortality in winter. Major differences in species identification between two independent observers on the same route, from 2009-2014, resulted from one being red/green colourblind. Possum (Trichosurus vulpecula) numbers dipped briefly in the 1970s, peaked in the 1990s, and have declined since then where there has been widespread poisoning to protect trees, birds, and limit bovine TB. Rabbits (Oryctolagus cuniculus) increased steadily after control was lifted in the 1980s and now dominate the road-kills; the effect of RHD, introduced in 1997, does not register, probably because it causes short-term local oscillations. Hedgehog (Erinaceus europaeus) numbers show no clear trend and, unlike the other species, North and South Island patterns differ; the lower numbers in the South may reflect the cooler climate. Brown hares (Lepus europaeus) remain relatively stable, with a doubling in numbers since the 1980s in parallel with rabbits. The predators, cats (Felis catus) and mustelids (Mustela furo, M.erminea, M. nivalis), followed their prey increase until the 1990s when extensive predator control began; they then declined, although rabbit and rat (Rattus rattus, R. norvegicus) numbers continued to rise. In the 1950-60s, far more live mammals were being seen on and from roads, and adaptations to traffic have evolved. These historical records may be useful to assess future changes in road-kill following the adoption of silent electric cars, driverless vehicles, and public transport.
