“…Las rutas y el tráfico son una fuente tan importante de mortalidad de fauna debido a que atraviesan sus rutas migratorias y áreas de campeo, interfiriendo en su libre desplazamiento (Harris y Scheck 1991;Coffin 2007;Bager y Rosa 2010;Cramer et al 2015). Al cruzar los caminos, muchas especies resultan atropelladas (Coffin 2007), y sus cadáveres se transforman en alimento para especies carroñeras, que también resultan atropelladas (Arroyabe et al 2006;Bager y Rosa 2010;De La Ossa y Galván-Guevara 2015;Monroy 2015;Cuyckens et al 2016).…”

“…Nevertheless, values for shared species are low between WU and other structures which indicates that different species go through the WU than the ones using drainages. WU clearly allows bigger (heavier) species to cross compared to drainages (e. g. carnivores [ 37 ]; herbivores [ 80 ]). When comparing culverts, both BC and CP have similar species composition despite that BC appears with lower values in this case.…”

Conservation implications for jaguars and other neotropical mammals using highway underpasses

The Nuevo Xcan-Playa del Carmen highway in Quintana Roo, bisects the vegetation corridor connecting two Jaguar Conservation Units (JCUs): Yum Balaam (north) and Sian Ka´an (south). The project´s main goal was to describe differential use of available crossing structures (wildlife underpasses and culverts) by mammals present along this highway. We set 28 camera traps along the 54km stretch of the highway covering wildlife underpasses (10), and culverts such as box culverts (9) and pipes (9) from September 2016 until March 2017. A total of 24 jaguar crossings have been recorded exclusively using wildlife underpasses, including four males and two females. At least 18 other mammal species including five of the target priority species (protected by Mexican law) were documented, all of which were native except for two invasive species. In terms of species using the crossing structures, we identified 13 species using wildlife underpasses, nine using concrete box culverts and 10 using concrete pipes. Wildlife underpasses show higher diversity values (Shannon´s exponential index = 5.8 and Inverse Simpson´s index = 4.66) compared to culverts because they allow bigger species to cross. We recommend more highways along the jaguar´s distribution should develop mitigation measures to allow for wildlife connectivity. Wildlife underpasses, along with retrofitted culverts, could help secure not only the permanence of this species by facilitating the functional connectivity between populations but have positive impacts on other neotropical mammalian fauna as well.

“…Ungulates (hoofed mammals) occur naturally across all continents except Australia and include deer, moose and buffalo, which tend to gather in groups and move long distances. Consequently, they need to frequently cross LTI to access seasonally available resources (Cramer et al, 2015). Many species of ungulates are large-bodied, occur in high abundances and tend to move in herds, leading to their frequent involvement in WVCs.…”

The development of linear transport infrastructure (LTI) can have a variety of direct and indirect impacts on protected and conserved areas (PCAs) and other intact areas with high biodiversity and ecological connectivity values. Poorly planned and constructed roads, railways and canals can sever habitats, disrupt ecosystems and threaten species. However, a growing number of solutions are available for overcoming these challenges, balancing the social and economic benefits of LTI development with ecological well-being. This Technical Report provides an overview of practical, feasible science-based strategies for PCA managers, transport practitioners, industry, conservationists and other stakeholders interested in biodiversity and ecological connectivity conservation in, and adjacent to, PCAs. It identifies effective solutions that can be used in a variety of contexts around the world and promotes best practices for the various phases of infrastructure development: planning, design, construction, operations and monitoring. Furthermore, it underscores the need for cross-sectoral commitments to good governance, effective policies, and financing for avoiding and mitigating the impacts of LTI on the environment.
