2022 onward Orkney North Isles Breeding Wader project - Habitat indicator species

Annual vegetation surveys carried out on lowland wetland sites, where habitat enhancement works have taken places across the North Isles of Orkney. The presence of ten positive indicator plant species (or genus) are recorded during breeding wader surveys, as part of a completing a Wader Scorecard which was developed by RSPB in conjunction with NatureScot. As the survey route follows transects spaced 200m apart, it is possible that some species recorded as absent during the survey were present elsewhere on site and absence records have therefore been excluded. Species included in the dataset are: Bogbean, cuckooflower, lesser spearwort, lousewort spp., marsh cinquefoil, marsh marigold, marsh pennywort, meadowsweet, ragged robin & cotton grass spp.
