Summer has not yet given up, the heat is returning once again. The Styrian Nature Conservation Association has taken some interesting measurements in Graz. These show how cooling hedges can be - and that short-cut grass radiates a lot of heat.

The measurements were taken the previous week, in the middle of the recent heatwave. The head of the Nature and Biodiversity Conservation Union, Johannes Gepp, took the thermometer in his hand - and feels vindicated in his plea for native hedges, and not just because they promote biodiversity.
