trees, cities, climate
The project overview
City trees fulfil manifold important functions such as improving the microclimate and air, absorbing noise or structuring places. In cities, drought and heat are generally more intense and other stress factors (e.g. air pollution) burden trees. Therefore, trees in cities are "living laboratories" enabling an analysis of stress mechanisms and responses as well as estimations of expected future changes, e.g. with respect to expected climate change. CITREE will provide a tool to monitor urban tree growth. Citizens have the ability to participate in tree monitoring as well as see and learn how their trees are growing.
How to participate?
The focal point of CITREE are band dendrometers, which are easy to install and cheap and used for measuring changes in circumference and thus growth of trees. Dendrometers installed on city trees will be read out by citizens, who will have access to the CITREE database via QR code and smartphone.
What happens to the contributions of citizen scientists?
The CITREE database will collect growth data of all equipped city trees and provide the data set for involved citizens, the broad public, public authorities and scientists.
