This project explores the hidden life that covers the soil surface in the Caatinga, a unique and threatened dryland biome in northeastern Brazil. We will investigate the biodiversity and ecological importance of biological soil crusts (biocrusts) - living communities formed by bryophytes, cyanobacteria, and algae that act as natural guardians of the soil. These tiny organisms play a big role: they help prevent erosion, retain moisture, and strengthen ecosystem resilience in the face of desertification.
Through field surveys, we will document which species occur in degraded areas and how they are spatially distributed across the landscape. In addition, we will test innovative restoration strategies by applying biocrust inoculation techniques directly in the field. Our goal is to stimulate biocrust growth, stabilize fragile soils, and contribute to the recovery of desertified sites. By combining biodiversity research with practical restoration actions, this project highlights the power of small organisms in sustaining dryland ecosystems and promoting a healthier future for the Caatinga.
