On June 25, 2025, together with the Google team, we carried out an important ecological action on the grounds of the Pawilon Edukacyjny Kamień in Warsaw. Our goal was to remove Canadian goldenrod – an alien, invasive plant species that poses a threat to the local environment. Around 40 people took part in the event, working with great enthusiasm to clear two plots around the pavilion, collecting 6 large piles of goldenrod, which will be disposed of properly by Warsaw Greenery Department. It was a day of real environmental care, education, and collaboration in the name of local biodiversity.
Goldenrod – beautiful but dangerous
Although Canadian goldenrod (Solidago canadensis) may catch the eye with its golden flowers, it poses a serious threat to native nature. It is an invasive species that spreads rapidly and suppresses the growth of native plants, effectively depriving them of space, light, and nutrients. Its presence means reduced biodiversity and, ultimately, a weakened ecosystem – including plants, insects, birds, and small animals that depend on the local flora.
That’s why efforts to control and remove it are so important – especially in environmentally valuable areas like the surroundings of the Kamień Pavilion, which also serve as educational and recreational spaces for Warsaw residents.
Hands-on work – restoring balance
During the action, we focused on manual removal of goldenrod – a time-consuming method, but one that is safe for the remaining vegetation. Working in teams, we cleared two plots overgrown with dense stands of this plant. Our work resulted in 6 large piles of green mass, which will be safely processed by municipal services according to procedures for invasive plants.
Hands-on work in the field brings more than just visible results – it leads to a real understanding of the problem, connects us to nature, and restores a sense of agency. Working together outdoors shows that ecology is not just about theory or information campaigns, but about concrete decisions and effort put into restoring natural systems.
Learning by doing – the power of direct experience
One of the greatest values of such events is the chance to experience nature up close. Observing how goldenrod displaces other species, how difficult it is to uproot, and understanding why it can’t just be left alone – leaves a lasting impression on participants. Environmental education doesn’t have to take place in classrooms – it can happen in these very moments, on the grass, with a spade in hand.
The Google team approached the task with incredible engagement and curiosity. There were questions, discussions, and exchanges of observations – all in an atmosphere of openness and a desire to understand the human impact on urban greenery.
Urban green spaces – places of resilience and relief
Actions like this also have a broader, long-term purpose. Urban greenery isn’t just about aesthetics – it is a natural barrier against the effects of climate change, such as droughts, heatwaves, or floods. The more diverse the vegetation, the more resilient the entire ecosystem. By removing invasive species, we give native plants a chance to regenerate and restore balance, supporting the entire web of life from fungi to pollinators.
The Pawilon Edukacyjny Kamień is a space for education, dialogue, and joint action – an ideal place to demonstrate practical nature conservation in the city. And we, together with Google, were proud to contribute to that mission.
