How green is my city?

I was invited by The London Tree Officers Association to show how UKMap can map the tree canopy of London.  The full presentation is here.
  One key fact we learnt was that in New York, the Tree Officer had shown that for every $1 spent on trees New Yorkers gained $5 of benefit.
Yet in London we don't even have a tree canopy map or even an idea of how the population of trees are changing. 
With a quick bit of UKMap analysis I showed that 11% of east side of London is covered with trees.
 Significant or not?  Too early to tell. 
But with climate change dominating our horizon, trees are an easy way to reduce our emissions.
