D1C1 has an unknown assessment due to the lack of adequate information on bycatch rates and total values. Furthermore there is no agreed approach at regional level, on the most suitable algorithm (i.e. PVAs, modified Potential Biological Removal or other population dynamic modelling approaches) to use for calculating sustainable removal in both the EU on Barcelona convention context. A limit value considering the ecological requirements of the species, could be calculated by applying the Potential Biological Removal (PBR) to the best available population abundance estimate and after regional or sub-regional consultation.

Summer abundance estimates are: ASI 2018 95%C.I.= 28.907-40.406 and MSFD 2021 95%C.I.= 34.064-51078

This parameter was not assessed because no index areas, representative of the national nesting population are identified in the MAD MRU due to the low nest counts occurring in the subregion.

This parameter was not assessed because no index areas, representative of the national nesting population are identified in the MRU.

The parameter describes the annual distribution of nesting events with respect to their presence in coastal 10x10km cells of the italian WME MRU during the period 2018-2021 (described as annual percent of coastal cells occupied by nests per subregion in the period 2018-2021).The parameter development is line with the indications provided by the EU and regional guidelines for art.8 and IMAP indicator assessment. Details on the data sets, sources, coverage figures and references are described in the summary report. The observed nesting distribution in the MAD MRU between 2018-2021 is very low (1-2 coastal cells are occupied by nests on an annual basis for a total quadriennial distribution coverage involving four coastal cells in the period 2018-2021). There are no previously reported data to compare the presently observed spatial coverage. However comparison with information provided by bibliographic sources describing nesting distribution in the past decade suggests a generally stable if not increasing nesting distribution condition consisting of patchy and sparsely distributed nesting events observed mostly in the southernmost sectors of the MAD MRU coastline. The nesting distribution range of occupied coastal cells is therefore considered to be good.

The parameter has been positively assessed by the Range Tool HD (http://discomap.eea.europa.eu/App/RangeTool/) with a 200 km gap distance. Caretta caretta exhibit highly variable dispersal patterns in the Mediterranean, influenced by diverse feeding habitats (Schofield et al., 2013). Long-distance movements of over 200 km have been reported (Luschi, P., & Casale, P. 2014)

A standardized approach for assessing the suitability of the habitat conditions of critical marine turtle areas at sea is not addressed by the EU MSFD or HD guidance documents on reporting. Considering that the northern Adriatic hosts important neritic feeding and wintering grounds for most Mediterranean loggerhad turtle stocks and that physical disturbance to some of of the benthic seabed habitats distributed within these areas is relevant, the assessment of the habitat condition of the critical marine habitats is considered unknown based on a precautionary approach. D1C5 is considered an irrelevant parameter for the assessment of nesting habitat conditions since the distribution and number of nesting events in the MAD MRU is limited and therefore poorly indicative of a GES assessment. No assessment is therefore conducted for the nesting habitat conditions of the italian MAD MRU.
