The ‘The Royal Athenaeum of Gilly’ is a public school located in Charleroi, Belgium. The surrounding landscape is marked by the decades of carbon exploration and industrial sites which came to an end in the 1970’s.

Over the past years, the community of Gilly has come together with the goal to create a greener identity. ‘Gilly School’ is part of it! Over the past five years, they have introduced ecology & sustainability in their daily practice. Children have a weekly course focused on the environment.

An educational forest for ‘Gilly School’ will support the next generation in learning about native species, biodiversity and regeneration.

“I have been teaching biology over the past 8 years at ‘Gilly School’. Our goal has been to reconnect the young generation with nature. I teach them about the environmental crisis but more so, about the solutions that give hope to this earth. A mini forest will be a unique opportunity for them to learn about species, biodiversity and regeneration.”

This pocket forest has become an integral part of the school community and is a real source of pride for students; this has translated into the care the forest has received and how it has fared during the harsh summer of 2022. As with other European forests that experienced these harsh conditions, survival rate is excellent even if growth rate is a little slow. The school organised regular waterings of the forest during the hottest days and various classes has been involved in this.

Gilly School Forest is increasingly being used to support the teaching of science and geography, particularly in addressing topics such as: biodiversity, climate change, sustainability and citizen initiative.

Survival Rate: 95%

Tallest Tree: 150cm

Somehow, a few trees were broken. However, shoots are popping up which show good resilience in adversity. The trees have more than doubled in size: from 40cm on average on the day of plantation to 100 -150 cm today.

Maintenance was done once. A little watering at one point helped at the beginning of summer. However, it was decided not to do maintenance in the forest for the rest of the year so that the green cover offers protection against desiccation in times of drought. It is great to see so many wildflowers and biodiversity resulting from the decision. Adventitious plants do not harm the trees in this case because they are low on the ground.

The soil was noticeably bad before our intervention, there was lots of rubbles and it was very compacted. We noted almost no life in the soil. I’m glad that the soil is coming back to life. We managed to regenerate the soil and provide sound ecological conditions for the trees to thrive! The school community is happy about it. We expect much more growth next year, 2021-22.
