Table 1. Description of the five activities proposed to the participants during the three activity days.

Activity name	Description	Aim	Participants
1. Gardening	Helping gardeners to sow and plant a 30-m2 flower meadow to attract a variety of pollinators.	Participative (Children & adults)	20
2. Hotel for pollinators	Building boxes for pollinators in wood and bamboo (Bambusoideae) to provide nesting opportunities for different pollinating insects. Participants could build small boxes to take home or place in the garden or help to build large pollinator “hotels”.	Participative (Children & adults)	31
3. Nesting birds	Discovering the bird species that nest in the gardens and learning to recognise birds by their song.	Knowledge (Children & adults)	50
4. Treasure hunt for spontaneous plants	Participants were given a map of the garden and pictures of eight spontaneous plant species, which they then went looking for. The activity ended with explanations on the species found.	Knowledge (Children)	23
5. Miniature garden	Creating a small garden in a sandbox using only natural materials (e.g., tree bark, leaves, pebbles, mosses).	Interactive (Children)	42

The aim of each activity is classified into three categories: (1) learn about urban nature (“knowledge”); (2) participate in conservation efforts (“participative”) (3) interact with natural features (“interactive”). The activities were held throughout the day; both adults and children participated, but only the adults were followed and registered (total number of registered participants: 102).
