->Range:
Pulsatilla patens is an eastern element in the flora of Latvia, associated with geomorfological formations from sandy, granular soil and continental climate. Species is more concentrated in Latvia's SE section. There are no complite investigation of all known locations conducted. There are no changes in range, but there is tendency to decrease number of locations and number of individuals in several regularly monitored sites. ||
->Population: 1252 records of species exist in Nature data base "Ozols", but almostly 2/3 of them are repeated records. Therefore at least 400 localities (dots and polygons) of species might be recorded from 1991 to 2018. In 2017 Nature Conservation Agency investigated part of historical and existing locations (~ 100 dots and polygons) and concluded that in 34 locations species has dissapeared. Therefore assumed that there is population decrease during reporting period (2013-2018), but no precise data available to evaluate the amount of decrease. The number of individuals varies between locations (data from reporting period 2013-2018) - the richest populations are counted to be more than 500 individuals (three locations), 200-300 individuals (9 locations), 100-200 individuals (22 locations), 50 -100 individuals (28 locations), 10 - 50 individuals (77 localities), 2-10 individuals (145 localities), 1 individual (94 localities).
The minimum number of individuals calculated by summing up data where number of individuals indicated plus at least one individual per location where number of individuals is not recorded. The maximum number calculated by summing up data where number of individuals indicated plus 10 individual per location where number of individuals is not recorded. ||
->HabInfo: P.patens mainly inhabits dry pine forests on fairly poor mineral soil, mesotrophic forests with pine and spruce, rich forests with a pine overstorey, slightly mixed with deciduous trees, forest margins and heath. There is tendency of eutrophication that decreases available habitat area. P.patens is light depanding species and natural disturbances and/or targeted management is necessary for species long term survival. Monitoring data in some sites shows that the number of localities and/or number of individuals decreases due to habitat quality loss, for example, Gauja National Park, Kemeri national park, therefore short term direction evaluated as decreasing. No statistically robust data about situation outside N2000 areas, but monitoring data shows that number of individuals increases after forest tinning or clearcut (more open space for species available), but it is short term result - after couple of years population size decreases due to succession. ||
->Future: N/A ||
->Conclusion: N/A ||
->JustificationThreshold: Not applicable. ||
->Other: Extinction of Pulsatilla patens localities usually occur when there are changes in habitat due to natural succession, as a result there is increase in undergrowth shrub density, in ground vegetation increase of subshrubs (blueberries, cowberries) and mosses. As this is light-demanding species, than it is mainly found in sparse and dry forests, in the strip between roadside and forest. During the first years of clear cut number of Pulsatilla patens specimens rapidly increases, but when clear cutting starts to become overgrown/ reforested then particular locality rapidly get decreased or perished.

->Range: ETC’s (2018) range tool was used to generate a standardized grid map and to calcu¬late the range. Observations registered in the national database Artportalen (www.artportalen.se) were used to assess the distribution of the species. Sites monitored by flora guardians are included in the database. ||
->Population: The main part of the population occurs on Gotland where the total population size was estimated to 380 000 in 2004 (Petersson 2004, Lindell 2007). Available data does not indicate that the population size has changed since then. It is assumed that the current population size is sufficient for long-term viability and that it has been stable since 1995. The CV reported here is the best available population estimate since 1995 and FRP is thus equal to the CV. However, recent studies have noted that populations on Gotland mainly consists of old established plants and that the recruitment of new individuals is low (Lindell 2007, Björkén et al. 2015). It is therefore suggested that the overall assessment for the Population parameter (11.2) is reported as U1 – unfavourable-inadequate. ||
->HabInfo: It is assumed that the senescent populations (populations on Gotland mainly consists of old established plants and that the recruitment of new individuals is low , Lindell 2007, Björkén et al. 2015) is a consequence of a reduced suitability of the habitat, i.e. the habitat has a reduced quality. Three recorded M-ranked pressures and four M-ranked threats suggests that the Habitat for the species is Inadequate-poor. ||
->Future: It is assumed that the implemented conservation measures are not wide-ranging enough to improve parameters assessed as ‘poor’ to ‘good’. Consequently, the assessment of future prospect is equal to the current conservation status for all parameters. ||
->Conclusion: The overall assessment of conservation status was made following the evaluation matrix in the ETC Explanatory Notes & Guidelines. ||

->Range: Podana w pkt. 5.1. wartość zasięgu jest większa od raportowanej w roku 2013 (18641 km km) i wyliczona została z użyciem nowego narzędzia. ||
->Population: Ad. 6.2. Obfitość kwitnienia gatunku w znacznym stopniu zależy od warunków klimatycznych w danym roku. Kwitnienie jest słabsze, kiedy w lecie jest sucho i gorąca, a poprzedzająca go zima ma łagodny przebieg. W czasie monitoringu prowadzonego w latach 2017-2018 na 34 stanowiskach stwierdzono 3 724 rozety sasanki otwartej, w tym około 3 000 na jednym stanowisku "Sasanki w Kolimagach", które aktualnie jest najobfitszym, udokumentowanym stanowiskiem tego gatunku w Polsce. Populacje pozostałych stanowisk są znacznie mniejszej. Tylko na trzech stanowiskach to 100 lub więcej rozet. Przeważają populacje małe, które składaja się tylko z kilku osobników. Na dziewięciu z 34 monitorowanych stanowisk gatunku w ogóle nie znaleziono. W poprzednim raporcie (2013) liczebność populacji określono na od 6 500 do 6 600 rozet. Ostatnie wyniki monitoringu z 2016 r. wskazują, że w regionie populacja gatunku zmniejszyła się i obecnie liczy 6 000 - 6 100 rozet.
Ad. 6.7. W raporcie poprzednim (2013) krótkookresowy trend populacji określono jako nieznany ('x'), natomiast z obecnej perspektywy jest trend spadkowy (-). ||
->HabInfo: Każdy kolejny etap badań przyczynia się do lepszego zrozumienia dynamiki siedlisk monitorowanych gatunków. W poprzednim raporcie (2013) kierunek krótkookresowego trendu siedliska określono jako nieznany ('x'), natomiast w obecnym raporcie (2019) jako pogarszający się (-). ||
->Future: N/A ||
->Conclusion: W poprzednim raporcie (2013) ogólny trend stanu ochrony był nieznany ('x'). ||
