“…For example, of the 27 studies that investigated road-related mortality in up to three related species, 15 studies involved species of conservation concern, while the remaining 12 studies considered the common and widespread species that are often reported in wildlife-vehicle collisions. Amphibians appeared to generate the most concern, with a number of multiple-taxa studies finding that they made up the highest percentage of roadkills (as much as 80% recorded, [9][10][11][12]). Studies warn that with many amphibian populations already declining globally any additional nonnatural mortality could further impact population persistence [13].…”

“…Furthermore, a total of six studies related increased road mortality rates of wildlife, not including amphibians, with distances from wetlands or water sources (e.g., [17]). Research included in this review also highlighted two concerns, 1) that maintained road-side habitat provided quality forage, nesting resources or breeding habitat for many species, thus attracting wildlife, which in turn increased their risk of wildlife-vehicle collisions [21,31,32,40], and 2) that road mortality increased with proximity to a protected area [9,10]. The latter indicates that any existing road or future road development in proximity to a protected area has the potential to impact the species that area may be attempting to protect.…”

Effects of Road Density and Pattern on the Conservation of Species and Biodiversity

The development and presence of roads can reduce landscape permeability, lead to habitat loss, and increase habitat fragmentation. It is these fundamental changes in landscape structure that can have both direct and indirect impacts on the conservation of species and biodiversity. In this review, I examine 215 research studies conducted between 2011 and 2015 that explore the impacts of roads and road networks on a wide range of species. I divided these studies into four main categories: 1) the direct effects of roads on wildlife, 2) the indirect effects of roads on wildlife, 3) the consequences of road networks on wildlife populations, and 4) survey design and mitigation including both innovations and evaluations. I found that the majority of studies (38%) explored the indirect effects of roads on wildlife, including displacement, fitness consequences, and road crossing ability of wildlife. Nevertheless, despite there being a pressing need to understand how existing road networks impact wildlife and how increasing road density may influence local and regional population persistence, only 10% of the studies considered the implications of road networks on wildlife. However, there is an increasing trend towards the development of predictive models that can be used for a better understanding of road network impacts, assess landscape connectivity, and devise mitigation. This review also highlighted the continued need to devise and evaluate mitigation measures so transportation authorities and conservation practitioners may be better equipped to address the ecological implications of roads and proposed road development.

“…On the other hand, there is less large-sized wildlife hit by vehicles in tropics than small ones and thus the damages and human losses should be lower. However, the diversity of species killed in collisions with vehicles is higher in tropics, and thus the conservation issues may become more relevant than security ones, especially in protected areas (Dornas et al, 2012;Garriga et al, 2012).…”

Habitat or matrix: which is more relevant to predict road-kill of vertebrates?

We believe that in tropics we need a community approach to evaluate road impacts on wildlife, and thus, suggest mitigation measures for groups of species instead a focal-species approach. Understanding which landscape characteristics indicate road-kill events may also provide models that can be applied in other regions. We intend to evaluate if habitat or matrix is more relevant to predict road-kill events for a group of species. Our hypothesis is: more permeable matrix is the most relevant factor to explain road-kill events. To test this hypothesis, we chose vertebrates as the studied assemblage and a highway crossing in an Atlantic Forest region in southeastern Brazil as the study site. Logistic regression models were designed using presence/absence of road-kill events as dependent variables and landscape characteristics as independent variables, which were selected by Akaike's Information Criterion. We considered a set of candidate models containing four types of simple regression models: Habitat effect model; Matrix types effect models; Highway effect model; and, Reference models (intercept and buffer distance). Almost three hundred road-kills and 70 species were recorded. River proximity and herbaceous vegetation cover, both matrix effect models, were associated to most road-killed vertebrate groups. Matrix was more relevant than habitat to predict road-kill of vertebrates. The association between river proximity and road-kill indicates that rivers may be a preferential route for most species. We discuss multi-species mitigation measures and implications to movement ecology and conservation strategies.Keywords: connectivity, conservation, landscape ecology, rivers, road ecology.Habitat ou matriz: qual é mais relevante para prever atropelamentos de vertebrados? ResumoNós acreditamos que nos trópicos, precisamos de uma abordagem de comunidade para avaliar os impactos das estradas sobre a vida silvestre, e então, sugerir medidas de mitigação para grupos de espécies ao invés da abordagem de espécie-foco. Compreender quais características da paisagem indicam eventos de atropelamento podem também fornecer modelos que podem ser aplicados em outras regiões. Nós pretendemos avaliar se habitat ou matriz é mais relevante para prever eventos de atropelamento para grupos de espécies. Nossa hipótese é: matriz mais permeável é o fator mais relevante para explicar os eventos de atropelamentos. Para testar essa hipótese, escolhemos vertebrados como a assembléia estudada e uma rodovia cruzando uma região de Mata Atlântica no sudeste do Brasil como área de estudo. Modelos de regressão logística foram criados usando presença/ausência de eventos de atropelamentos como variáveis dependentes e características da paisagem como variáveis independentes, os quais foram selecionados pelo Critério de Informação de Akaike. Nós consideramos um conjunto de modelos candidatos contendo quatro tipos de modelos de regressão simples: modelo de efeito de habitat; modelos de efeito de tipos de matriz; modelo de efeito da rodovia; e, mode...

“…The proposed investment may make animal migration difficult or even impossible and cause deaths as a consequence of car accidents. It is also indirectly connected with fragmentation of ecosystems and degradation of habitats, as well as deterioration of conditions as a result of emission of pollution and noise (Bohatkiewicz, 2008;Forman & Alexander, 1998;Forman & Deblinger, 2000;Garriga et al, 2012;Kiczyńska & Weigle, 2003;Saunders et al, 2002). One of the simplest ways to allow migration of animals is construction of animal crossings (Jędrzejewski et al, 2006).…”

“…A special aspect of a road's effect is the impact on nature conservation areas (Albers, Ando, Bu, & Wing, 2012;Garriga et al, 2012). Hence, it is highly recommended to project several road locations as alternative variants, to indicate the possibility to avoid protected areas or at least limit the negative effect on such areas (Kiczyńska & *Corresponding author.…”

Abstract. The effect of road location on natural and landscape elements is presented in this paper. Special care was focused on nature conservation areas located along three proposed road variants. Landscape metrics as a supplemental tool for selection of the most environmentally friendly road variant were here examined. The matrix method was used to analyse the potential negative effect of the road on the nature and landscape. Landscape metrics were found to be a very useful supplemental tool to evaluate the potential negative effect of the planned road on the environment. Moreover, based on our study we can also clearly relate this element to the effect on nature conservation elements. One of the most important features is the possibility to calculate certain metrics based on existing land use information without the need for field analyses, as well as obtaining specific values, which may be more objective than visual landscape assessment.
