• 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

• 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
N07	85.00
N14	15.00
Total Habitat Cover	100

Other Site Characteristics

The bedrock underlying this site is low permeability fossiliferous limestone. This is overlain by permeable sands and gravels mainly derived from limestone. The peat layer is underlain by relatively impermeable lake clays. Esker ridges of sands and gravels lie to the north and south of the site. Part of the old cutover bog has been converted to improved grassland and this is included in the site for hydrological reasons.

4.2 Quality and importance

Mongan Bog is an example of a small to medium sized raised bog site which contains examples of the Annex I habitats active raised bog, degraded raised bog and depressions on peat substrates (Rhynchosporion). The centre of the site is dominated by a core of uncut high bog which contains an unusually large number of pools dominated by open water. The uncut high bog core is surrounded by old cutover surface which is regenerating into a mosaic of heath and low scrub. The relatively rare sedge Rhynchospora fusca has been recorded from wet pools within the site. In the past, the bog was used by wintering Anser albifrons flavirostris but the geese appear to have deserted the site in recent years. The site supports breeding Numenius arquata and Gallinago gallinago.
