Nature

Threatened aquatic habitats with rock bottom refer to freshwater or marine environments characterized by rocky substrates that are at risk due to human activities and environmental changes. These habitats, vital for diverse species such as fish, invertebrates, and aquatic plants, face threats from pollution, sedimentation, dam construction, invasive species, and climate change. The degradation of rock-bottom habitats disrupts ecological balance, reduces biodiversity, and impairs ecosystem services like water filtration and spawning grounds. Conservation efforts are essential to protect these unique and vulnerable ecosystems from further decline.

Background

The vulnerability of aquatic habitats with rock bottoms emerged as a global concern in the late 20th century, when ecologists documented declines in specialized flora and fauna due to pollution, sedimentation, and hydrological alterations. International research initiatives, such as the EU’s Water Framework Directive assessments, highlighted the unique ecological roles of these habitats and the accelerating threats they face, prompting targeted conservation efforts and increased monitoring across continents.
