The Guardian has a story about a forthcoming report from the Greater London Assembly which will say that trees are valuable for the well-being of communities but are under threat from a combination of insurance companies and risk-averse local authorities.

The evidence on the benefits of trees is well-summarised on a webpage maintained by Warwick District Council. Research by Kuo and Sullivan found that crime rates and domestic violence are reduced by as much as 50% in urban areas with a high proportion of trees.
