2023-2028 trial participants: observations start on April 1st!
MyGardenOfTrees is a participatory science project supported by the European Commission and led by a team of researchers from the Swiss Federal Research Institute WSL. The aim of MyGardenOfTrees is to evaluate the growth and regeneration capacity of silver fir (Abies alba Mill.) and European beech (Fagus sylvatica L.) through experimental gardens across Europe. Observations obtained from these gardens will be used to develop a prediction tool for foresters to help them build forests better adapted to climate change.
In this video, the project PI, Dr Katalin Csilléry, explain the steps of the project from seed collection to the development of a prediction tool.
Over 300 micro-gardens have been established across Europe in the framework of the 2023-2028 trials.
25 large common gardens "macro-gardens" have been established by collaborating research institutes and universities across Europe.
Diversity exists not only in the areas where the micro-gardens were set up, but also among our participants. We asked them to send news or pictures about their micro-gardens to share their colorful experiences, different points of view, and photos that capture many faces of micro-gardens, so we can show them to others in our newsletter. Information arrives continuously at info@mygardenoftrees.eu. Thank you for sharing!
Among our participants are secondary schools and universities, which means that the MyGardenOfTrees project has an educational role, too.
“Our micro-garden is in good condition. My colleagues and I did the spring monitoring according to the schedule. As we work in school, we also use the micro-garden for field teaching. Some of the monitoring was done by our students (forestry technicians) with our help and control.
Fir seedlings are in better condition regarding their number. We only have five beech seedlings left.
The general experience is very positive. Our students also like to participate, as that was one of our main goals when we applied for the project.
Sometimes it's tiresome when we have to do the monitoring and complicated to coordinate it with our regular obligations, especially when the weather conditions are bad.”

Research institutes are also interested in the outcome of the project.
“Our observations at plot 393 are proceeding well, even though the plot is fenced and is located right next to a spruce forest stand. We are hesitant to remove the tree shelters because deer and bears have repeatedly breached the fence, entered the plot, and browsed the young fir trees that are also growing nearby. Our plot is regularly visited by a brown bear - a female with cubs. The cubs are very curious about our experiment and sometimes move or knock over the tree shelters.
A major problem in Slovakia in terms of afforestation and natural regeneration is currently the very high population density of game, particularly deer. Silver fir is especially attractive to them, and as a result, it is unable to regenerate naturally in many forest stands.
On this particular plot, young seedlings and saplings are often damaged by late spring frosts. However, our young beech seedlings from different provenances were not affected by frost, as they are protected by the taller herbaceous vegetation in the understory.
Over the course of this year and the previous year, we have observed increased mortality in the AN-CAUC provenance.”

Enthusiastic nature lovers (e.g. an environmentally conscious community in Italy) also think that the future of forest is important.
“Being part of MGOT has been a transformative journey for our experimental community project, Gello3000, in Tuscany. We’ve been joined by many passionate visitors—botanists, researchers, and tree lovers—who have lent their hands and eyes during our monitoring sessions. Tracking the survival of these seedlings feels like an ongoing adventure, bringing us closer to our forest and deepening our understanding of plant behavior across the seasons.
Continuing the monitoring over multiple years has breathed new life into our discussions about climate resilience and the vital role trees play in this precious ecosystem. Summer 2026 has been particularly dry and hot in our region, and watching the seedlings struggle with these dire climatic conditions—alongside several forest fires in the surrounding areas—has shown us the urgency of taking action now. Cooperating against climate change and managing forests sustainably is more important than ever!”

Of course, the majority of our participants are foresters. They either have their own private forests or work for forestry companies. Their practical skills and field experiences are highly valuable for carrying out the project in practice all over Europe.
“All the beech seeds have been eaten by small rodents.
Germination seems to depend on very local factors; so sometimes I have 10 seedlings in the same spot, and sometimes none at all.
In the Belgian Ardennes, fir stands are very rare; 50 percent of our conifers are spruce, with the remainder consisting of Douglas fir, larch and pine. The seedlings seem to be coping well with the current drought – two months without any significant rain...
Many seedlings are developing a small side shoot, perhaps due to a lack of light.”

“First of all, I think that the experiment is well planned and the communication is very well organized.
In my opinion, the condition of the Fagus seeds and their pre-treatment prior to sowing were not adequate, so I do not think adequate conclusions can be drawn considering their survival. There were some poor-quality seeds, and they weren’t treated before sowing, etc. I would have been curious to see what results we would have obtained if the seeds had been of good quality.
In contrast, the Abies seeds were full of surprises. In that case, the propagating material was generally good and viable. I was astonished that they did not die out completely during this summer drought, not even the seedlings that were exposed to full sunlight.
Of course, neither the summer nor the drought has ended yet.
I also think it’s good that you’re paying attention to environmental conditions and observing the herbaceous vegetation.
I consider myself lucky to be able to take part in the monitoring. In today’s changing world, I find it very useful and forward-looking.
It would be worth including other tree species in a similar experiment, ones that are less tolerant of shade.”

Five years is a long period of time when anything can happen in a forest. Fallen trees after a heavy storm in ID 252. The trees were successfully removed and thanks to the strong seed protectors, most of the seedlings survived.
“The site, which was once a clearing of dense ferns where nothing else could grow, has completely changed following weekly maintenance to control the ferns (one clearing per week). In fact, the vegetation today is completely different from what existed before the garden was established. If I hadn’t controlled the vegetation, the upper layer would be a closed canopy consisting entirely of ferns (Pteridium aquilina) throughout the entire garden, with a mixture of blackberries (Rubus fruticosus) underneath.
It should be noted that controlling the ferns allowed for the establishment of fairly abundant natural regeneration of Pseudotsuga menziezii, Betula pendula, Cytisus scoparius, Sambucus nigra, Quercus robur, Salix caprea, and Sorbus aucuparia. All of these species did not exist here before. In fact, even if they had sprouted, the shade cast by the ferns would have caused them to wither away.
Since last year, I’ve had to raise a number of the protective covers for the beech trees, and also because Douglas firs had taken over the covers next to the fir and beech seedlings. This year, given the heat wave, I did not remove the new fern growth starting in mid-June in order to provide some light shade.”

In some micro-gardens, which were set up on clearings, herbaceous vegetation is abundant, and competition for light is higher,
like in gardens ID 94 (France) and ID 96 (Poland)
And last, but not least, there are micro-gardens in protected areas as well.
