Dear All: I am looking for literatures on the impacts of road or railway on environment, especially the impacts on plant species diversity and the spreading of invasive species. I know the Road Ecology by Richard Forman is a good beginning. However, can anyone direct me to more recent and related sources? Thank you very much for your help.
