"Surrey is *England's* most wooded county, there are far woodier bits of Scotland!"
You miss the point; the writer was referring to the fact that Surrey has got more wood than any other county. High consumption of Bolivian marching powder in Surrey may have something to do with that.
Since the population of Scotland is said to be 5,168,500 (http://www.scotland.org/facts/population/) and a recent calculation for the population of Surrey is 1,113,100 (http://www.surreycc.gov.uk/sccwebsite/sccwspages.nsf/LookupWebPagesByTITLE_RTF/2009+mid-year+estimates+of+population?opendocument) I contend that Surrey is indeed more densely wooded than Scotland. Indeed, soon Surrey will invade Scotland in pursuit of more lebensraum. Watch out Scotland.
