Why Did The Squirrel Cross The Road?

ScienceDaily (Sep. 2, 2008) — A study has shown that red squirrels can and do make use of special crossings set up over busy roads.

A researcher from the University of Leeds’ Faculty of Biological Sciences conducted a survey to discover whether red squirrels living in Loch Lomond and the Trossachs National Park were using rope bridges installed by a local wildlife group.

This kind of bridge is usually installed at sites where there have been fatalities recorded but up until now no-one has collected any data to show whether or not they are actually used by the animals.

Having analysed his findings, Stephen has now concluded that the creatures are definitely using the bridges, but that it is important to put them in the right place. He says, “In areas where there is a high population of squirrels then the new bridges we put up were being used within a couple of days, not surprisingly we also found that baiting the bridges with food also encouraged the squirrels to use them.
