Using private gardens to conserve Minuartia smejkalii - a novel approach for ex situ conservation
We currently observe a tremendous loss of species due to the ongoing global change. Ex situ conservation provides an important tool to counteract species losses and thus helps to maintain biodiversity. Here, we present a setup which involves 19 private gardens and 2 botanical gardens as sites of ex situ conservation using Minuartia smejkalii, an endangered serpentinophyte endemic to Czechia as a case study. To create suitable habitats in the gardens, artificial serpentine mounds were built, combining soil from natural sites with serpentine rocks and gravel from nearby quarries. We investigated how the plants performed at ex situ conservation sites compared with plants growing in natural habitats and how well these artificial sites represented the conditions at the natural sites. We assessed plant performance using plant functional traits including tuft diameter, chlorophyll fluorescence, chlorophyll content, and specific leaf area (SLA). We found that even though abiotic factors of the ex situ conservation sites (temperature, soil properties and shading) did not entirely match the natural conditions and plant mortality was higher and performance lower under ex situ conditions, we managed to create many independent M. smejkalii populations and increase its variability in plant functional traits, which might facilitate its survival. Using private gardens as ex situ conservation sites also helped to raise awareness on the conservation of M. smejkalii through engagement of the local community and the gardeners and thus, this proves to be a useful and powerful technique in plant conservation.
期刊介绍:
Biological Conservation is an international leading journal in the discipline of conservation biology. The journal publishes articles spanning a diverse range of fields that contribute to the biological, sociological, and economic dimensions of conservation and natural resource management. The primary aim of Biological Conservation is the publication of high-quality papers that advance the science and practice of conservation, or which demonstrate the application of conservation principles for natural resource management and policy. Therefore it will be of interest to a broad international readership.
