->Range: N/A ||
->Coverage: Flanders has a good habitat mapping programme, but with some knowledge gaps (remaining old fieldwork, amount of the habitat in a polygon with several vegetation types not exactly known, …). We use minimum (= minimum of certain habitat), maximum (maximum of certain habitat + mean of uncertain habitat) and a best single value (mean of certain habitat). ||
->HabCondition: Spartina maritima should be present but it is known that this species is extinct in Flanders for several decades. Based on that knowledge we conclude that the total area is in a not-good condition. Because this species is extinct for several decades we consider the short-term trend as stable. Information on typical species (Red List status) and spatial coherence of the habitat is determined directly on the regional level. As a consequence, this information cannot be integrated in the areas given in field 6.1, but it is used to assess the conclusions on specific structures and functions (field 10.3). ||

->Conclusion: Abweichend von der Empfehlung in den Guidelines bei einer FV-Bewertung der Spezifischen Strukturen und Funktionen einen Schwellenwert von 90 % Flächenanteil in gutem Zustand anzuwenden, wurde in Deutschland im Regelfall der Schwellenwert von 80 % beibehalten, um unter anderem die Kontinuität zu den vorherigen Bewertungen zu wahren. ||

->Future: Même si les populations de Spartina maritima semblent aujourd'hui assez stables, l'isolement des différentes stations couplé à une probabilité d'hybridation avec Spartina anglica ne permettent pas d'envisager les tendances et perspectives de façon favorable. ||

Information provided in the field 2.7.5: Reported additionnal information: ||
->Range: Distribution map is based on vegetation maps within Natura 2000-sites and relevé data in- and outside Natura 2000-sites over a period of 12 years. Some vegetation maps still contain uncertainties and relevé data may have gaps, but we assume that total distribution is well covered for 90% or more. A change of 10% is used as a threshold for positive or negative trends. Favourable Reference Values are based on Bijlsma et al. (2014), WOt report 125. Range data and trends are based upon maps in Dutch Rijksdroehoek co-ordinates, while distribution maps have been delivered in ETRS co-ordinates. ||
->Coverage: No reliable new data on area available ||
->HabCondition: More than 90% of the habitat is dominated by Spartina anglica, a young species developed through hybridization of Spartina maritima and the non-native Spartina alterniflora and doubling of chromosomes afterwards; we consider sites with S. anglica as having a moderate quality (unfavourable) and sites with S. maritima as being favourable; the positive trend is based on rediscovery of locations with Spartina maritima (good quality), a species that was thought to be extinct. ||
->Future: S&F is likely to improve as a result of new locations of S. maritima and S. x townsendii, which indicate better quality ||
->Conclusion: The positive trend is because of new locations of the (supposed to be extinct) Spartina maritima. ||
->JustificationThreshold: 10% decrease/increase is used as threshold for all trends, due to uncertainty in data; a formula with 75%/25%-thresholds is used for conservation status of Structure & Function and Typical species. ||

->Range: N/A ||
->Coverage: The short term trend direction is considered to be decreasing by 1%/yr or less, based on the rate of decline identified in England. ||
->HabCondition: N/A ||
->Future: Future trend of Range is Overall stable; Future trend of Area is Very Negative - decreasing >1% (more than one percent) per year on average; and Future trend of Structure and functions is Very negative - important deterioration ||
->Conclusion: Conclusion on Range reached because: (i) the short-term trend direction in Range surface area is stable; and (ii) the current Range surface area is more than 10% below the Favourable Reference Range.
Conclusion on Area covered by habitat reached because: (i) the short-term trend direction in Area is decreasing by more than 1% per year; and (ii) the current Area is more than 10% below the Favourable Reference Area.
Conclusion on Structure and functions reached because habitat condition data indicates that more than 25% of the habitat is in unfavourable (not good) condition.
Conclusion on Future prospects reached because: (i) the Future prospects for Range are bad; (ii) the Future prospects for Area covered by habitat are bad; and (iii) the Future prospects for Structure and functions are bad.
Overall assessment of Conservation Status is Unfavourable-bad because one or more of the conclusions is Unfavourable-bad.
Overall trend in Conservation Status is based on the combination of the short-term trends for Range - stable, Area covered by habitat - decreasing, and Structure and functions - decreasing.
The Overall trend in Conservation Status has changed between 2013 and 2019 because the Structure and functions trend has changed from increasing to decreasing. ||

->Coverage: The estimate of habitat area is based on an extrapolation method or expert based judgement, using when appropriate the techniques suggested by the ETC. Such methodologies may have a degree of uncertainty that cannot be quantified; for this reason, the values included in the report are to be considered approximate estimates. ||
