The research on the population of this species was carried out in 2006. Number of specimens, density and spatial structure were examined on 5 × 5 m experimental areas. Floristic composition of phytocoenoses were characterized, too. In Kamieniec and Nawodna the population of Gentiana cruciata was found in Adonido-Brachypodietum pinnati communieties for which Gentiana is characteristic species. In Nawodna it is estimated on 1370 specimens. The greatest population of Gentiana cruciata appears on this area and its characteristic feature is the diversity of length of stems and the number of flowers. The numerous population from Kamieniec is characterized by the changebility of biometric parameters because of diversified habitat conditons. The population from Zdroje takes up the smallest area (106 specimens) where the most frequent blossoming was marked. The part of blossoming specimens was smaller because the worsening of light conditons. The aggregate type of spatial distribution was found in all examined populations.plUznanie autorstwa-Użycie niekomercyjne 3.0 PolskaGentiana cruciataPomorze Zachodnieroślina zagrożonastruktura populacjiendangered plantpopulation structureWestern PomeraniaDyscyplina::Nauki rolniczeArticle2300-5378
