Méthodes de conservation des espèces végétales menacées

Abstract

This dissertation addresses the conservation of endangered plant species, with a particular focus on assessment mechanisms and scientific conservation strategies. The study aims to analyze the fundamental concepts related to biological vulnerability and to identify the causes underlying the degradation of plant cover, particularly in the context of climate change and increasing human pressures. Internationally recognized methodologies for risk assessment and classification are reviewed, along with an overview of several threatened plant species in Algeria to illustrate the current state of biodiversity. The study also discusses comprehensive conservation approaches based on the integration of in situ and ex situ conservation methods. It concludes that the adoption of integrated strategies is essential to ensure the sustainability of plant diversity as a biological heritage for future generations
