Too many roads Roads have done much to help humanity spread across the planet and maintain global movement and trade. However, roads also damage wild areas and rapidly contribute to habitat degradation and species loss. Ibisch et al. cataloged the world's roads. Though most of the world is not covered by roads, it is fragmented by them, with only 7% of land patches created by roads being greater than 100 km2. Furthermore, environmental protection of roadless areas is insufficient, which could… 
Importance of Roadless Areas for the European Conservation Network
Protected Areas are a main conservation tool to halt biodiversity loss. However, their performance has been often questioned and the need to improve their effectiveness is now more apparent than
Spatial Assessment of the Potential Impact of Infrastructure Development on Biodiversity Conservation in Lowland Nepal
TLDR
It is revealed that there is currently large spatial heterogeneity in habitat quality across the landscape as a result of current anthropogenic threats, and that three areas in particular could have up to 40% reduction in habitatquality as a consequence of the planned infrastructure in Nepal.
Roadless areas in Brazil: land cover, land use, and conservation status
Roadless areas (RLAs) are places with little to no influence of roads, usually sustaining well-preserved habitats, whereas road-effects zones (REZs) are areas affected by roads. Here, we map and
Road development in Asia: Assessing the range-wide risks to tigers
TLDR
It is found that roads were pervasive, totaling 134,000 km across tiger conservation landscapes (TCLs), even in tiger priority sites and protected areas, and decision-makers are urged to make sustainable road development a top priority.

TLDR
A global map of remaining terrestrial wilderness is created following the established last-of-the-wild method, which identifies the 10% of areas with the lowest human pressure within each of Earth's 62 biogeographic realms and identifies the10 largest contiguous areas and all contiguous areas >10,000 km2.
A Review of the Impacts of Roads on Wildlife in Semi-Arid Regions
TLDR
This work assesses mitigation measures and collate methods to identify the impact of roads on wildlife populations and their associated ecosystems, with a particular focus on recent advances.
Global areas of low human impact (‘Low Impact Areas’) and fragmentation of the natural world
TLDR
It is demonstrated that when habitat fragmentation is considered in addition to habitat loss, the world’s species, ecosystems and associated services are in worse condition than previously reported.
Forest fragmentation in China and its effect on biodiversity
TLDR
This paper reviews fragmentation trends – historical and current – in China, the fourth largest country on Earth, and explores its consequences, showing that the drivers of forest fragmentation are shifting from mainly agricultural expansion to urbanisation and infrastructure development.

A global strategy for road building
TLDR
This large-scale zoning plan seeks to limit the environmental costs of road expansion while maximizing its benefits for human development, by helping to increase agricultural production, which is an urgent priority given that global food demand could double by mid-century.

Abstract Context. Roads are a pernicious form of habitat loss for many wildlife populations because their effects often extend far beyond the roads themselves, giving rise to reduced wildlife

TLDR
The results clearly demonstrate that placing roads within protected areas can seriously reduce their capacity to sustain wildlife populations and potentially threaten livelihoods of indigenous groups who depend on these resources for their survival.

SUMMARY Roadless and low‐traffic areas are typically large, natural or semi‐natural areas that have no roads or few roads with low‐traffic volume. They are relatively unaffected by roads and

TLDR
This article has developed a detailed map of the terrestrial ecoregions of the world that is better suited to identify areas of outstanding biodiversity and representative communities and addresses the disparity in resolution between maps currently available for global conservation planning and the reality of the Earth’s intricate patterns of life.

Abstract: Roads are a widespread and increasing feature of most landscapes. We reviewed the scientific literature on the ecological effects of roads and found support for the general conclusion that
The response of faunal biodiversity to an unmarked road in the Western Amazon
TLDR
Investigation of the potential for biodiversity impacts from an unmarked road within a rainforest protected area in Western Amazonia finds increasing proximity to the road had a negative effect on amphibian and understorey bird communities, whilst butterfly and overall diurnal bird communities responded positively.
Ungulate behavioral responses to the heterogeneous road‐network of a touristic protected area in Africa
TLDR
The results show that even within a protected area that has been well-visited for a long time, wildlife can still be affected by roads and traffic, and has ecological and management implications for protected areas where touristic activities are largely based on driving.
