->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, …). Therefore, 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). About 20 ha of scrub (2160) has been cleared for the restoration of open habitat types 2130 and 2190. However, the spontaneous expansion of scrub in these open habitats exceeds the area of clearings. Scrub expansion is largest in fixed mobile dunes. The FRA being smaller than the actual area enables further restoration of open dune habitat (dune slacks 2190 and priority habitat grey dune 2130) at the expense of dune scrub 2160. This is necessary since possibilities for restoration of open dune habitat elsewhere are very limited. ||
->HabCondition: For the Flanders part of ATL the areas given in field 6.1. are based on a representative monitoring network. Indicators for habitat structure, vegetation development and environmental disturbances are taken into account. The ‘Best single value’ of the area (field 5.2) is multiplied with the % amount of the sample plots in good and not-good condition.
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). ||
->Future: N/A ||
->Conclusion: The new method is based on plot information and leads to a different conclusion on specific structure and functions ||

->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. ||

->HabCondition: Fourrés de la dune bordière et du contact xérosère/hygrosère (périphérie des pannes, plaines et dépressions dunaires inondables) en état de conservation défavorable inadéquat (surface parfois en régression, forme encore pionnière du Sambuco nigrae - Hippophaetum rhamnoidis, altération de la typicité des espèces végétales) par rapport aux fourrés mésophiles des arrière-dunes, en état de conservation beaucoup plus favorable (surface en extension significative sur certains massifs, diversification de la structure des fourrés et de leur composition floristique, rôle écologique majeur pour la reproduction de certains passereaux comme le Rossignol philomèle dont la densité de couples nicheurs à l'hectare est importante...) ||
->Future: Les tendances et perspectives futures de l'habitat générique sont surtout celles de l'une de ses composantes phytocénotiques, masquant peut-être une dégradation insidieuse de la diversité phytocénotique et floristique de cet habitat. ||

->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. The 2013-map was not correct however, and the previous reported range should have been 6100. As we consider a change of 10% as a threshold for positive or negative trends, there is no genuine change. 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; however, trends are assessed as positive based on Mücher et al. (2017) "Meijendel-Berkheide pilot study", and NEM-LMF plots which indicate increase of shrubs and trees in dune grassland (http://www.clo.nl/indicatoren/nl1535-vegetatie-duinen). ||
->HabCondition: There is no data on area with good S&F available. There is no method for assessing S&F for this habitat type yet, but the assessment of S&F (FV) should have been the same in the previous reports. ||
->Future: N/A ||
->Conclusion: S&F assessment based on previous report (which was based on SDF analysis); no TS analysis. Trend in 2013 was not reported, but supposed to have been positive, due to increasing area. ||
->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. ||

->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 Positive - increasing >1% (more than one percent) per year on average; and Future trend of Structure and functions is Overall stable ||
->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 approximately equal to the Favourable Reference Range.
Conclusion on Area covered by habitat reached because: (i) the short-term trend direction in Area is decreasing by 1% per year or less; and (ii) the current Area is not 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 good; (ii) the Future prospects for Area covered by habitat are poor; 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 - stable.
The Overall trend in Conservation Status has changed between 2013 and 2019 because the Area trend has changed from stable to decreasing, and the Structure and functions trend has changed from increasing to stable. ||

->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.

->Range: Wartość podana w polu 4.1 (400km2) jest wyższa niż wartość podana w raporcie z 2013 r. (313 km2), ale faktyczny zasięg nie uległ zmianie w porównaniu z poprzednim okresem raportowania. W aktualnym okresie raportowym wartość podana w polu 4.1 została wyliczona przy użyciu dedykowanego narzędzia (Range Tool) przygotowanego przez ETC/BD oraz EEA, w sposób automatyczny na podstawie rozmieszczenia kwadratów, w których występuje siedlisko w regionie biogeograficznym. Przy obliczaniu powierzchni zasięgu siedliska zastosowano „gap distance” wynoszący 40km, a wyliczony przez narzędzie zasięg nie został przycięty do granic Polski. ||
->Coverage: N/A ||
->HabCondition: Do określenia powierzchni siedliska w dobrym, złym lub nieznanym stanie (pkt. 6.1) wykorzystano rozkład ocen parametru struktura i funkcje na stanowiskach monitoringowych oraz wartość powierzchni siedliska w regionie podaną w pkt. 5.2 c). Przyjęto następujące założenia:
- minimalna powierzchnia siedliska w dobrym stanie to jest powierzchnia wskazana w pkt 5.2 c) x procent stanowisk monitoringowych, na których parametr struktura i funkcje został oceniony na FV
- maksymalna powierzchnia siedliska w dobrym stanie to jest powierzchnia wskazana w pkt 5.2 c) x procent stanowisk monitoringowych, na których parametr struktura i funkcje został oceniony na FV i U1
- minimalna powierzchnia siedliska w złym stanie to jest powierzchnia wskazana w pkt 5.2 c) x procent stanowisk monitoringowych, na których parametr struktura i funkcje został oceniony na U2
- maksymalna powierzchnia siedliska w złym stanie to jest powierzchnia wskazana w pkt 5.2 c) x procent stanowisk monitoringowych, na których parametr struktura i funkcje został oceniony na U1 i U2
- minimalna i maksymalna powierzchnia siedliska o nieznanym stanie to jest powierzchnia wskazana w pkt 5.2 c) x procent stanowisk monitoringowych, na których parametr struktura i funkcje został oceniony na XX
Monitoring siedliska przyrodniczego prowadzono na 4 stanowiskach. ||
->Future: N/A ||
->Conclusion: Przy określaniu oceny parametru struktura i funkcje stosowano inne progi wartości niż podane w wytycznych. Przyjęto następującą waloryzację parametru:
- Jeśli na ponad 50% monitorowanych stanowisk stan struktury i funkcji siedliska został oceniony jako właściwy FV i jednocześnie na mniej niż 20% stanowisk został oceniony jako zły U2 – ocena FV
- Inne kombinacje – ocena U1
- Jeśli na ponad 33% monitorowanych stanowisk stan struktury i funkcji siedliska został oceniony jako zły U2 – ocena U2 ||
