The use of scenarios has an enormous potential ... -
Best practice—Is natural revegetation sufficient to achieve mitigation goals in road construction?
Mehlhoop, Anne Catriona; Skrindo, Astrid Brekke; Evju, Marianne; Hagen, Dagmar (Peer reviewed; Journal article, 2022)Aims: The area influenced by road construction is large, and measures to re-establish vegetation in disturbed areas are routinely carried out to reduce impacts on biodiversity. However, goals of mitigation measures are ... -
