What is CSI Trees? <\/div><\/span>\n\t\t\t\t\t\t\t\n\t\t\t<\/path><\/svg><\/span>\n\t\t\t<\/path><\/svg><\/span>\n\t\t<\/span>\n\n\t\t\t\t\t\t<\/summary>\n\t\t\t\t

CSI Trees is a research project that seeks to identify tree species that are resistant to changing urban climates\u2014such as heat, drought, salinization, and extreme rainfall\u2014so that these trees can continue to grow healthily in urban environments in the future.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

Can you already advise which trees are most climate-resistant? <\/div><\/span>\n\t\t\t\t\t\t\t\n\t\t\t<\/path><\/svg><\/span>\n\t\t\t<\/path><\/svg><\/span>\n\t\t<\/span>\n\n\t\t\t\t\t\t<\/summary>\n\t\t\t\t

At this moment, we are unable to provide substantiated and location-specific advice on climate-resistant tree species. Within this project, all relevant atmospheric and soil factors are being mapped out one by one. The combination of these factors determines the suitability of a tree species for a specific planting location in terms of its ability to grow well there.\u00a0<\/p>

Advising on tree species at this stage would be based on assumptions or limited substantiated estimates. This is precisely how climate resilience has often been determined up to now: on the basis of so-called \u201cexpert judgment.\u201d Given the rapid and ongoing changes in the climate, we consider this approach to be insufficiently reliable and possibly even misleading.<\/p>

We have therefore made a conscious decision to only issue recommendations when they are scientifically robust and applicable to specific locations.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

Where does the name CSI Trees come from? <\/div><\/span>\n\t\t\t\t\t\t\t\n\t\t\t<\/path><\/svg><\/span>\n\t\t\t<\/path><\/svg><\/span>\n\t\t<\/span>\n\n\t\t\t\t\t\t<\/summary>\n\t\t\t\t

The name CSI Trees<\/b> refers both to the working method and the content of the project. It stands for a targeted search for tree species that are suitable for the changing urban climate.<\/p>

At the same time, the name has a second meaning: CSI<\/b> also stands for Citizen Science Investigator<\/i>. This emphasizes that citizens are actively involved in the research and in the significance that trees have for their living environment. In this context, ten Dutch municipalities investigated which characteristics of street trees are most appreciated by residents.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

Climate change is causing urban trees to experience increasing stress, such as heat and drought stress, and as a result, many of the current tree species will struggle in the coming decades. CSI Trees is investigating which tree species are more resistant to these conditions.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

CSI Trees uses a computerized system that links the expected future urban climate to climate conditions in the natural distribution area of tree species worldwide. This identifies tree species that are likely to perform well in future urban and rural conditions. In addition, the physiological characteristics of trees are examined to assess their resilience.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

Yes \u2013 the project focuses on Dutch cities, but the methods and insights can be more broadly applied in other regions with similar climate changes. Municipalities and tree managers are invited to use the results in future green planning.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/details>\n\t\t\t\t\t\t

Trees are selected based on climate data, physiological responses to stress, and compatibility with the expected urban climate conditions in 2100. This results in a list of species that are resistant to future heat, drought, and other abiotic stress factors.

Yes, it is possible for students to participate in CSI Trees.
