Did you know?
Trees make a big difference in urban areas: they help to cool cities and fight climate change, thus providing you with an agreeable, enjoyable environment and the city’s wildlife with food and shelter.
However, trees are in danger, especially in cities. They suffer from severe stress like drought, making them more susceptible for pests and diseases.
The number of ill trees has increased in the last few years. Some tree diseases like ash dieback and chestnut dieback have progressed tremendously.
But you can make a difference!
There are many questions:
Which trees are less susceptible to pests and diseases in cities?
Do some diseases attack only particular species?
Are there differences between particular areas for some pests and diseases?
Can you find pathways of spreading?
Is the number of trees affected by mistletoes in big cities larger than in rural areas?
Can ashes be found that are resistant against ash dieback?
You can help us and scientists to monitor and protect our trees in urban areas, but also in woodlands.The best time to complete this survey is between May and September.
