Grasslands' vegetation, that of Campo Imperatore upland in particular, has very different characteristics depending on morphology, wind and snow level: the small valleys are quiet wet and feature rare plant species of northern origin, while the moraines and the peaks have a typical steppe-like vegetation of eastern origin. Because of such complexity the project area safeguards many of the habitats listed in the Directive of the same name, many of them are priority habitats.
