Acorns to oak trees - can mapping our trees help manage flood risk?
The UK has hundreds of millions of trees. In general, these trees are very poorly mapped, particularly in urban areas and there is no standard for those that have been spatially recorded. Currently the mapping and managing of these valuable assets is carried out in an ad-hoc fashion often involving costly fieldwork or using ‘broad brush’ techniques which rely on data inputs from non-specialists. Bluesky has created a National Tree Map derived from high-resolution aerial photography, accurate surface models and other geographic data, including infrared imagery.
There have been several studies looking at how planting trees can reduce the peak height of flooding downstream. How can managing and mapping our trees reduce the long-term flood risk for many of our cities and towns?Back to all speakers
