In an open letter, a group of Estonian scientists argues for the importance of maintaining existing species-rich park areas and emphasizes that any drastic alterations or intense mowing can disrupt ecological processes. They respond to a piece published in Tartu Postimees that questioned the politicians' commitment to restoring green areas. The scientists warn that transforming these ecosystems abruptly could lead to a regression, essentially restarting the ecological processes that have already developed over time.

The scientists highlight that urban nature has direct implications for public health and wellbeing, acting as a vital component for sustainable urban living. They assert that these green spaces contribute to biodiversity, improve air quality, and enhance mental health, thus advocating for strategies that conserve and maintain these areas rather than attempting to overhaul them significantly.

Overall, the letter reflects a growing concern among environmental scientists about the impacts of urban development on ecosystems. The scientists are calling on policymakers to consider the long-term ecological and health benefits of preserving these environments instead of chasing quick fixes that may ultimately be detrimental.
