Description
Czech nature is rich and diverse but also contains many vulnerable species. These species need an active protection. A document called an action plan contains guidelines for nature conservation authorities, researches and owners of land how to maintain endangered species populations. It is a special tool which provides complex knowledge of species and recommends the measures how to support the species. The project is about implementation of the measures. The Bohemian Sand Pink (Dianthus arenarius subsp. bohemicus) is a specially protected species therefore the “Action Plan for Bohemian Sand Pink” was prepared in the year 2008. The project meets the target of the state environmental policy of the Czech Republic for 2012-2020. The main objective of the project is the implementation of the action plan by monitoring and research studies in the Kleneč area, one of the two areas of the species occurrence. The project outcomes are increasing of the species population by sowing seeds from cultivation ex situ and improving knowledge of local population and environment. The project outputs are data from monitoring, data from phytosociological screening, data from monitoring of microclimate values and analysis of soil samples. The research output are results of four studies - study of reproduction and reproductive ecology, the study of links between plant and phytophage, tracking and determination of natural pollinators and results of entomological surveys. Project will also include a publicity part. The target group of the project is primarily nature-conservation authorities. Secondarily, the protection and connected activities will carry out awareness-raising in the general public via education.
Summary of project results
Dianthus arenarius is a neoendemic species whose natural occurrence is limited to the area of SCI Kleneč, in the past on the hillside in Vražkov (Kovanda 1986), and artificially also in the Important landscape element Stráň Na Kamenici. Therefore, this species is listed in the category of critically endangered species according to Annex II. The Decree 395/1992 Sb. and even in the Red list of species (C1). In the Red list of the IUCN is Dianthus arenarius bohemicus ranked among the vulnerable species (VU). The Habitats Directive of the European Economic Community (directive 92/43/EEC, Habitats Directive) mentions this in the Annex II. as “species whose conservation requires the designation of special areas of conservation”; and in the Annex IV. as “species, which requires strict protection”. Convention on the Conservation of European Wildlife and Natural Habitats (the Berne Convention) includes it in Annex I as a “strictly protected plant species”. Activities have been done: Care about the species: Sowing the seeds Storage of seeds in the Gene bank Monitoring: Monitoring of population in SCI Kleneč Monitoring of population at KyškoviceCommunity ecology survey of the areas with tiered down of upper humus horizonMonitoring of the microclimatic valuesAnalysis of soil samples Monitoring and determination of natural pollinators of Dianthus arenarius subsp. bohemicusEntomological survey in SCI Kleneč The project was successfully realized. Each activity led to improve the state of dianthus populations (e.g. by sowing the seeds) as well as to improve knowledge about its population biology, the effects of other plant species, herbivores, pollinators etc. Overall, we can say that the situation of dianthus populations is good and that The Action plan for its rescue/ maintenance prospers to fulfill very well. Our results also confirmed that the management at the locality realized to dianthus profit is also very helpful to other organisms, especially many rare thermophilous and xerophilous invertebrates.
