Monitoring of Herminium monorchis

Monitoring of Herminium monorchis was established in 2014 at the three known localities for the species. A total of 40 permanent plots of size 50 x 50 m2 were established, and the number of ramets have been counted annually (except 2018) within the permanent plots. In 2016 a new locality was discovered, and monitoring was established here in 2020. In 2021, the monitoring was expanded and it now covers 67 plots, distributed at the localities Skipstadsand (15 plots), Skjellvik (27 plots), Teneskjær (15 plots) and Filletassen (10 plots). The dataset contains number of fertile and vegetative ramets within plots, and variables on vegetation structure in the plots.
