  • PF: for the habitat types that can have a non-priority as well as a priority form (6210, 7130, 9430) enter "X" in the column PF to indicate the priority form.
  • NP: in case that a habitat type no longer exists in the site enter: x (optional)
  • Cover: decimal values can be entered
  • Caves: for habitat types 8310, 8330 (caves) enter the number of caves if estimated surface is not available.
  • Data quality: G = 'Good' (e.g. based on surveys); M = 'Moderate' (e.g. based on partial data with some extrapolation); P = 'Poor' (e.g. rough estimation)

4.1 General site character

Habitat class % Cover

Total Habitat Cover

0

Other Site Characteristics

The marine site comprises the uninhabited islets of Pontikonissi and Prasonissi reefs, and extends 3nm about their coasts. This radius includes part of the North Evvoia coastline from Koutsoubri beach (northwest) to Ellinika (southeast). The total area spans about 85 km2 of the coastal seabed, exceeding depths of 200m.

4.2 Quality and importance

This marine site is particularly important for its circalittoral sciaphilic communities, both on hard and soft substrata. More specifically, it comprises well-extended and structured rhodolith beds, a sensitive deep subtype of Habitat Type 1110, hosting exceptional biodiversity of rarely reported species (e.g. Paramuricea macrospina, Cystoseira dubia, Sebdenia monardiana, Phymatolithon calcareum, Rodriguezella strafforelloi); Around the steep rocky coasts of Pontikonissi and Prasonissi islets, coralligenous assemblages (deep counterpart of Habitat Type 1170) also occur, with highly vulnerable facies of various erect anthozoans (e.g. Eunicella cavolini, Paramuricea clavata, Savalia savaglia) and sponges (Axinella spp), spanning depths of 30-80m (HCMR, 2013). Along the Evvoian coasts, Posidonia oceanica beds (Habitat Type 1120) and shallow reefs also occur at depths between 5-30m. The alien algae Caulerpa cylindracea, Lophocladia lallemandii, Falkenbergia hillebrandii and Womersleyella setacea have been detected in the area in yet low abundances. This is one of the very few marine areas in Greece for which the historical presence of the precious red coral (Corallium rubrum) has been confirmed (Chintiroglou et al, 1989).
