Anyone in Vienna and Innsbruck who is interested can also take part. Direct measurements of \u2018urban nature\u2019 and digital classification of the soil surface are used. In addition to gaining scientific knowledge, an important aim of the project is to emphasise the importance of urban trees for a healthy microclimate and thus for us all, as well as to make the public aware of the functions of the soil that are necessary for this.<\/p>\n\n\n\n<p><strong>The surveys in the Sparkling Science project include<\/strong><\/p>\n\n\n<div class=\"gutenberg__list\">\n<ul class=\"wp-block-list\">\n<li>The continuous monitoring of the diameter increment of trees using special measuring tapes (dendrometers) by the school children as well as other Citizen Scientists: The readings are sent to a database via a QR code and mobile phone. In this way, periods of stress for the trees (e.g. drought) can be recognised. In addition, the tree growth can be viewed almost \u2018live\u2019 by everyone.<\/li>\n<\/ul>\n<\/div>\n\n<div class=\"gutenberg__list\">\n<ul class=\"wp-block-list\">\n<li>Addressing tree vitality and the condition of the ground surface (\u2018green strips with bushes\u2019, \u2018soil compacted\u2019, &#8230;) using \u2018virtual city walks\u2019 by the children of the participating schools: Here, digital skills are expanded and the city can be experienced from a new perspective.<\/li>\n<\/ul>\n<\/div>\n\n<div class=\"gutenberg__list\">\n<ul class=\"wp-block-list\">\n<li>The delineation of surface categories on the aerial photograph by the project team within grid areas, incorporating the data collected by the children.<\/li>\n<\/ul>\n<\/div>\n\n<div class=\"gutenberg__list\">\n<ul class=\"wp-block-list\">\n<li>Measuring the height and diameter and assessing the vitality of all \u2018public trees\u2019 as well as the condition of the ground surface in nature by the project team.<\/li>\n<\/ul>\n<\/div>\n\n<div class=\"gutenberg__list\">\n<ul class=\"wp-block-list\">\n<li>Taking soil samples from the defined surface categories for laboratory analysis as well as measuring the infiltration rate of water: High infiltration capacity is particularly important in the event of heavy rainfall. Exemplary investigations are carried out together with the classes on the school grounds, the other locations are sampled by the project team.<\/li>\n<\/ul>\n<\/div>\n\n\n<p>These surveys can be used to extrapolate to the urban areas of Vienna and Innsbruck. This means that urban climate protection measures can be better planned and the results can contribute to improving national greenhouse gas reporting. The sealing rate is a particularly important parameter for a number of climate policy issues, such as the extent to which the soil is available for water and carbon storage and for vegetation growth.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Tree measurements &#8211; recording data, understanding nature<\/h3>\n\n\n\n<p>Pupils from three schools and other citizen scientists record the trunk thickness growth of 81 trees in the cities of Vienna and Innsbruck as continuously as possible. The measured values are then entered into a database. Most of the trees in Innsbruck were already equipped with dendrometers in 2017 via the completed Citizen Science project CITREE. You will therefore find a comparatively longer series of measurements for Innsbruck. The project team will use this measurement data to draw conclusions about (temporarily) favorable and unfavorable conditions for the trees.<\/p>\n\n\n\n<p><a href=\"http:\/\/www.citree.net\/\">Homepage for dendrometer measurement<\/a><\/p>\n\n\n\n<p><strong>Notes on measuring:<\/strong><\/p>\n\n\n\n<p><a href=\"https:\/\/youtube.com\/shorts\/aY0vzC74FIg\">Short Clip on YouTube (German)<\/a><\/p>\n\n\n\n<p>Please try to estimate as accurately as possible (to tenths of a mm).
