3.1 Habitat types present on the site and assessment for them

Annex I Habitat types						Site assessment
Code	PF	NP	Cover [ha]	Cave [number]	Data quality	A|B|C|D	A|B|C
						Representativity	Relative Surface	Conservation	Global
1110			1491	0.00	P	A	C	A	A

• 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)

3.2 Species referred to in Article 4 of Directive 2009/147/EC and listed in Annex II of Directive 92/43/EEC and site evaluation for them

• Group: A = Amphibians, B = Birds, F = Fish, I = Invertebrates, M = Mammals, P = Plants, R = Reptiles
• S: in case that the data on species are sensitive and therefore have to be blocked for any public access enter: yes
• NP: in case that a species is no longer present in the site enter: x (optional)
• Type: p = permanent, r = reproducing, c = concentration, w = wintering (for plant and non-migratory species use permanent)
• Unit: i = individuals, p = pairs or other units according to the Standard list of population units and codes in accordance with Article 12 and 17 reporting (see reference portal)
• Abundance categories (Cat.): C = common, R = rare, V = very rare, P = present - to fill if data are deficient (DD) or in addition to population size information
• 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); VP = 'Very poor' (use this category only, if not even a rough estimation of the population size can be made, in this case the fields for population size can remain empty, but the field "Abundance categories" has to be filled in)

4.1 General site character

Habitat class	% Cover
Total Habitat Cover	0

Other Site Characteristics

Pausanias submarine volcano lies in the Epidavros Basin of the Western Saronikos Gulf at a distance of 1.5 - 2 km to the NW of Methana peninsula, covering an area of about 12 Km2 (Nomikou et al. 2013; and references therein). This fully marine site comprises the extensive volcanic field between Pausanias Volcano and the northwest Methana Peninsula coasts, from Agios Nikolaos (Pausanias Springs) to cape Krasopanagia. On the north coasts of the Methana Peninsula, extensive shallow CO2 seeps occur, offering a natural lab for studying the effects of marine acidification (Baggini et al, 2014; 2015).

4.2 Quality and importance

Recent geological explorations revealed the presence of hydrothermal vents and springs (Nomikou et al. 2013), suggesting the site’s representativity as Habitat Type 1180 (Submarine structures made by leaking gases). The site also comprises extended detritic and muddy sediments (Habitat Type 1110), shallow and deep reefs (Habitat Type 1170) and Posidonia oceanica meadows (Habitat Type 1120). The hydrothermal Bubbling reefs have been reported from the Pausanias Hot Springs at Agios Nikolaos.
