  • Presence/absence data for vascular plant species in Companhia das LezĂ­rias and their habitat category. First, the most important vegetation units were selected, based on previous land cover maps. In each unit a 1km transect was established, passing trough the centroid of the habitat patch. A 2m margin was established for both sides of the transects and all species within it were registered. Period of field survey has been in May, June and July 2011.

  • The current distribution of Zostera spp. seagrass meadows along the Bulgarian Black Sea coast was studied. We used a combination of historical and recent observations of the habitat along the studied coastline. Remote sensing data (satellite images, sonar side-scans) was groundtruthed with georeferenced drop camera observations, scuba diving sampling and georeferenced scuba diving photo and video transects.
