Conservation Strategies for Mediterranean Plant Biodiversity

The Mediterranean Basin is recognised as one of the world’s foremost plant biodiversity hotspots, hosting a remarkably high proportion of endemic taxa shaped by millennia of climatic oscillations, complex topography and human influence. Conservation strategies in this region combine in situ measures—such as the designation and management of protected areas, ecological restoration of degraded habitats and the maintenance of habitat connectivity—with ex situ actions including seed banking, living collections and germplasm exchange. Area‐based prioritisation approaches, informed by species distribution modelling and phylogenetic analyses, have identified conservation hotspots and potential climatic refugia that warrant enhanced protection. The optimisation of existing networks, such as Natura 2000, alongside the creation of new reserves, aims to cover underrepresented taxa, especially those of high evolutionary distinctiveness. Participatory frameworks engage local communities and integrate traditional ecological knowledge to improve design and implementation of conservation programmes. Climate‐smart planning anticipates range shifts under warming scenarios, targeting high‐elevation “death‐zones” for proactive management. Ex situ collections underpin restoration and reintroduction efforts, while risk assessments based on international criteria guide prioritisation of resources. Together, these interconnected strategies seek to safeguard ecosystem services, preserve evolutionary heritage and inform best practices applicable to other global biodiversity hotspots.
