On the immediate outskirts of the old town, the stream of Lavernó begins a meander that has been biting the bank until creating a 15-20 m slope known as “la Timba”. Under this natural cliff, the water meanders and draws a green strip of about 12,000 m² converted into a biodiversity refuge and privileged viewpoint of the town.
Erosion, which for centuries had slowed urban expansion, required comprehensive action in 2012. With a budget of €750,000, the City Council and the Catalan Water Agency erected gabion walls and green walls, remediated landfills and provided the land with drainage to stabilize the slopes.
The result is a mosaic of habitats: in the anchorage, a riparian forest with verns, ash and small omedes; in the replains, semi-abandoned crops where honey-bearing species have been planted to attract butterflies; on the slopes, Mediterranean thickets that offer cover for reptiles. The space is also a nest for raptors such as the sparrow and the gamarús, and a corridor for mammals such as the buzzard or the fagina.
Today, environmental education projects are being developed here: a school garden, nest boxes and bird warning routes. Access is free and the walk, short but intense, allows us to understand the importance of urban ecological connectors.
La Timba continues to remind the Sadurninans that geology commands: where water gives, it also takes. Thanks to the collective effort, that gap that used to be scary has become a green balcony that humanizes the skyline of the capital of cava.
