Bird mortality through collision and electrocution are probably the most well-known ecological impacts of overhead power lines. However, our systematic review identified at least 26 other potential impacts on biodiversity that should be considered during ecological impact assessments. We developed a logical framework to help practitioners systematically identify and assess the potential ecological impacts of powerlines.

To reduce wildlife mortality from train collisions, we invented a warning system that emits flashing lights and bell sounds prior to the arrival of a train. A test of this system showed that animals fled earlier from trains in the presence of warning signals.

This study in Mexico showed that small wildlife experienced high rates of mortality and just like large charismatic species, they also require and deserve actions to avoid extinction.

Jaguars together with other neotropical species only used purpose-built wildlife underpasses under a highway in Mexico, even when ‘large enough’ drainage structures were available. Drainage structures may work as crossings for some species but can’t substitute proper wildlife underpasses.

Great Britain has seen traffic levels increase while bird species are declining but there is limited understanding about this link. This study assessed the spatial associations between roads and birds across Britain.

Around ~194 million birds and ~29 million mammals could be killed each year on European roads, and some species are particularly vulnerable to additional mortality even with low rates of roadkill.

The Hazel Dormouse is an arboreal mammal in Europe that are reluctant to cross at ground level. This study examines a bridge crossing structure, which shows its effectiveness for dormice in the UK.

This research is a review of the road ecology publications and research that have been done in Africa to date to identify the areas and species that have been researched and the lessons learned from these as well as to identify recommendations for further areas of research.
