This dataset describes the monitoring of restoration of six dry calcareous grassland sites.Sampling Description
Study Extent
Six localities in the inner Oslofjord. The current dataset includes baseline survey before restoration, and various numbers of revisits after restoration.Sampling
A set of permanent plots (0.5 x 0.5 m2) were systematically established along transects 10 m apart at each locality before restoration. All vascular plants were recorded with % cover. Structure variables (field layer cover, bottom layer cover, exposed rock and soil) were recorded in the plots as % cover. A circle of 5 m radius was established around each plot, and structure variables (cover of woody plants in the field layer, shrub layer and tree layer, cover of invasive vascular plants) as well as threat variables (erosion, vehicle tracks, human objects) were recorded as % cover. At the first revisit, only variables in the circle were recorded, including the restoration actions carried out.Method steps
- Methods are described in Evju et al. (2022), and in Roos et al. (2023).
