What do cities like Aachen, Berlin, Bonn, Frankfurt am Main, Karlsruhe, Cologne, Leipzig, Mannheim, Nuremberg and Weimar - and dozens of other cities and municipalities in the whole language area - have in common?
You all have Tree sponsorships.
The forms of these tree sponsorships are different: some cities have donation sponsorships, others casting sponsorships, and still others tree grate sponsorships. And some cities have all shapes at the same time.
The increasing need for watering urban trees is the main reason for this trend. Due to the longer dry periods and higher average temperatures, city trees increasingly require more irrigation (see text: Increasing problems for city trees). Yes: City trees can shade our cities and cool them through evaporation, but they themselves suffer greatly from climate change. Healthy city trees are for the urban microclimate central, but for this they must be healthy and have enough water.
In addition to the increasing need for watering, there is also a growing ecological awareness among the population. More and more people want to make their environment more ecological, more beautiful and more sustainable.
And at the same time, most cities and municipalities have to find a way to cope with the increasing need for watering without additional financial resources.
The Bavarian Federation of Nature Conservation writes:
«However, many city gardening authorities can only provide basic supplies for the stressed street trees because of the tight financial situation in many cities. City trees and especially street trees are therefore dependent on additional care and maintenance by committed residents. "
And this is where tree sponsors come in: They donate new trees and take care of the existing trees on the doorstep. And the cities are increasingly supporting this voluntary commitment.
Berlin, for example, has created its own website and mapped all the trees in the city. On the website https://www.giessdenkiez.de/ Citizens can find out about the water requirements of the individual trees and mark which trees they have already watered.
Berlin Friedrichshain-Kreuzberg With the support of baumbad, gave the tree godparents watering bags so that they can water the trees in their neighborhood particularly effectively. Why particularly effective? The bags are filled quickly, the water can be measured and then slowly trickles into the ground. This makes it easier for the godmothers to keep track of how much water they are giving the trees, depending on the needs or recommendations of the municipal companies. And the tree can absorb the water better.
Incidentally, Thomas Hoppe also recommends Plant manager of the Späth'schen Baumschulen in Berlin tree irrigation bags. And he also recommends them in connection with casting sponsorships.
You can find the whole video by Thomas Hoppe here:
As Thomas Hoppe describes, it is important to water the trees less often, but with 150 - 200 liters of water per irrigation cycle. The baumbad watering bags are ideal for this. They each contain 75 or 100 liters and can be combined with one another. Two bags make 150 or 200 liters per pour.
The motivation for tree sponsorships
Many people have a growing ecological awareness. You see pressing global problems and want to work for a more sustainable world. As a tree sponsor, many see the opportunity to get involved in the immediate vicinity and make a meaningful contribution to society. But there are other reasons as well.
The geographer Miriam Gruber has one in the science journal Springer Studie published about green sponsorships in Bonn. She writes about the motivation of the tree sponsors:
«For most godparents, sow comes firstberkeity and aesthetics. Several have started their engagement out of anger about constant garbage in the tree grates in their living area. In addition, it is important for those involved to be able to design their environment according to their personal ideas, as one godmother describes: 'I want it to be nice where I live'. Several respondents also cite the joy of gardening as a reason for sponsoring, especially if they do not have a garden themselves »
Gruber writes that the tree sponsorships would also improve communication and a sense of responsibility in the neighborhood. The godparents would be approached by people who would otherwise never have approached them in the street. And at the same time, the inhibition threshold for throwing away rubbish and for vandalism is increasing when flower beds are clearly cared for privately.
Advantages for the cities
So what are you waiting for? Tree sponsorships have advantages not only for the sponsors, but also for the cities.
Miriam Gruber writes in her study: "Parallel to these initiatives emerging from civil society, politics and administration have recognized the potential that committed citizens represent for the preservation of urban greenery, especially in times of highly indebted cities and correspondingly scarce municipal resources"
She names two other reasons for the city of Bonn to apply for green sponsorships: On the one hand, it is important for the city administration to accept civic engagement. On the other hand, the employees of the city administration see this as an opportunity to promote identification with urban green spaces.
