Native Plants
Abandoned quarries near your region could be quietly becoming some of the best wildlife habitat around — native plants colonizing bare, mineral-rich ground create open, sun-baked conditions that dense woodland never offers, drawing in species that have nowhere else to go.
Scientists checked in on an old quarry in Tuscany, Italy, that had been filled with a reddish industrial waste material and then simply left alone. Over the following decades, wild plants moved in on their own, and the researchers found a surprisingly diverse mix of native plants, animals, and insects — including thick bramble patches that shelter and feed wildlife. The open, dry, rocky conditions created by the quarry turn out to be genuinely rare in a region dominated by dense woodland, making this recovering wasteland unexpectedly valuable for nature.
Key Findings
Spontaneous revegetation since the late 1990s produced plant communities consistent with the natural successional series expected for the region, indicating ecologically self-directed recovery.
The southern portion developed a complex native plant assemblage, while the northern portion is dominated by bramble (blackberry), which provides food, refuge, pollination habitat, and shelter for wildlife.
The site's open, arid, mineral-rich microclimate contrasts sharply with the surrounding dense woodland, creating habitat diversity and supporting animal species that cannot thrive in closed-canopy forest.

Researchers surveyed a former gypsum quarry in Tuscany that was left to revegetate naturally after being reshaped with industrial red gypsum waste, finding that within just a few decades the site developed surprisingly rich plant and animal communities that add ecological diversity to the surrounding forest landscape.

This study illustrates results of an ecological survey performed on a former quarry area, morphologically reshaped from late '90 s, through the use of red gypsum obtained as a by-product from the p...
