The effectiveness of plant conservation: a case study of Opole Province, southwest Poland.
This work presents a method of assessing plant conservation effectiveness in a given region, which takes into account the legal, species-centered protection, ecosystem conservation, ex situ conservation, restorations and translocations, reintroductions, and monitoring. In order to illustrate the conservation effectiveness, both legally protected species of plants and threatened species were examined. The conservation effectiveness of legally protected species was estimated to have a low value of 23.328 points (pts) according to the methods of calculation. Habitat conservation is insufficient for these species. Almost 40% of all localities are deprived of any ecosystem protection. The conservation effectiveness of the threatened group of species scored a very low value of 13.46 pts. The major reason for this result is a very low level of species protection. Less than 30% of the threatened taxa are under legal preservation and some species from the Orobanche and Cuscuta genera are treated as harmful organisms, which it is obligatory to control within the province territory. Almost 30% of all localities of threatened species are deprived of any ecosystem protection and only 10% lie inside nature reserves. It is suggested that the conclusion of this investigation be used in the preparation and realization of the regional floristic diversity preservation strategy.
