COHNECS-IT Longitudinal COnnectivity and potential of Habitat of green verges depending on their Nature, SpEcies and the Context : a Systematic review about Transport Infrastructures
COHNECS-IT COnnectivité longitudinale et potentiel d'Habitat des dépendances vertes en fonction de leur Nature, des Espèces et du Contexte : une revue Systématique sur les Infrastructures de Transport
Résumé
The potential of habitat or corridor of linear transportation infrastructures verges (road and railway embankments, strips of grass under power lines or above buried pipelines, or waterway banks) for biodiversity remains controversial. The present work is the first systematic review of this potential role in temperate landscapes. Our searches identified over 45,000 articles about all biodiversity. During the successive screening stages, articles about non-insect species were put aside in order to comply with the time frame of the project. After critical appraisal, 14 articles remained, which did not allow to conduct a meta-analysis. A knowledge gap was identified regarding the role of corridor. The effect of the surrounding landscape on insect diversity of verges seems to depend on the type of landscape and on the taxa considered.
