Cruz de Carvalho, R., dos Santos, P. & Branquinho, C. (2018) Production of moss-dominated biocrusts to enhance the stability and function of the margins of artificial water bodies.Restoration Ecology, 26(3), 419-421. DOI:10.1111/rec.12688 (IF2017 2,544; Q3 Ecology)
Margins of water reservoirs associated with dams can have high-frequency tides, promoting soil erosion and nutrient leaching. We propose the use of biocrusts for restoration and ecological engineering purposes, due to their poikilohydric character, to stabilize reservoir margins. We promoted biocrust growth under controlled conditions, testing two types of substrate: native sand and organic substrate. After 2 months, biocrusts grew on organic substrate covering almost all the area, but not on native sand. This fast and easy nature-based solution for soil stabilization can be used as an environmental engineering tool in highly degraded sites.
