::As the original instigator of this article (who hadn't found the other article), I'd be okay with a merger, but would prefer to see this article expand along the lines that  suggests. I made the article after going to a seminar with this title, a seminar that was about a new multi-organisation project to mitigate the effect of roads on wildlife, and I see that seminar as a sign that this is a growing area of effort. The ecological theory has quite recently reached a level of real effectiveness, and money is becoming available for this sort of work, and I expect that the topic will grow.
