Botanic gardens unite to prevent species extinctions: the Global Conservation Consortium for Erica. Michael Pirie et al. describe an international project to prevent extinctions of species of Erica, the heaths or heathers. The ‘Global Conservation Consortium for Erica’ is coordinated at the Bergen University Gardens under the umbrella of Botanic Gardens Conservation International (BGCI). The authors describe the challenges of understanding and protecting species rich plant groups where much of the diversity is concentrated in biodiversity hotspots. Around 700 Erica species are only found in South Africa’s Cape Floristic Region. They explain how GCC Erica will address those challenges, including through both ‘in situ’ and ‘ex situ’ conservation.
