Glossary

This glossary includes most relevant terms used in this handbook. First version of the glossary was created during the development of the ‘Wildlife and Traffic’ handbook (Action COST 341) and it has been expanded with contributions from partners of the project Horizon 2020 ‘BISON’. Terms definitions are provided by legal texts, reference documents or by agreement between experts from both ecology and infrastructure. The organisations IENEPIARC, UIC, and ISO have also assisted and will contribute in future updates.

Habitat attrition
Habitat destruction due to progressive damage, loss or decline in quality.
Habitat fragmentation 
Dissection and reduction of the habitat area available to a given species - caused directly by habitat loss (e.g. land-take) or indirectly by habitat isolation (e.g. by barriers preventing movement between neighbouring habitat patches).
Habitat translocation
The relocation of a habitat from one place to another usually to avoid destruction of the habitat by infrastructure development.
Habitats related to Transport Infrastructures (HTI)
Green areas associated with transport infrastructure and usually managed by transport authorities and stakeholders. These areas include verges, resting sites, water retention ponds and other drainage elements, as well as fauna passages. These areas are inhabited by many animals, plants and other organisms which find refuge, food or other resources and can potentially have either negative or positive effects on natural ecosystems and landscape surrounding the infrastructure.
