BRAINCAKEConservation
Conservation is the maintenance of biodiversity through active management of ecosystems, while still allowing humans to use natural resources sustainably. It is a dynamic process: ecosystems are managed and, where damaged, restored (reclamation).
Conservation methods include:
• protecting habitats in nature reserves, national parks and marine protected areas
• managing succession (for example grazing or coppicing) to keep habitats with high biodiversity
• controlling or removing invasive species
• captive breeding and reintroduction programmes, and seed banks
• legislation and international agreements such as CITES, which controls trade in endangered species
