Can we learn from the ecology of the Bohemian gentian and save another closely related species of Gentianella

摘要: Bohemian gentian (Gentianella praecox subsp. bohemica) is an endemic taxon that occurs on the Czech Massif and together with Sturmian obtusifolia sturmiana) are only autumnal species of Gentianella large flowers in central Europe. Both have declined dramatically both population size numbers populations. The rescue programme, which recommended appropriate management measures, was adopted 2011. Here we study ecology this species, results programme explore possibilities using experience resulting from for improving viability second species. Long-term monitoring populations has shown regular mowing or grazing careful litter removal gap creation necessary its survival current climatic conditions. We found some ecological differences between these two closely related Gentianella. However, our empirical largest at a site where it thrives, general evidence gaps crucial successful establishment seedlings, indicate gaps, should also be as case programme. Artificial especially seedling regeneration oligotrophic meadows dense vegetation, last survive.
