Value of coral reefs
Biodiversity, home of 25% of marine fish
Shoreline protection
Food
Impacts of global warming on BD in Arctic
ecosystems moving pole ward, loss of tundra, fragile food webs damaged
Invasive species in Galapogos
60% of endemic plants threatened, need to eradicate rodents and removing the alien Quinine tree
Udzungwa mountains national park
Locals involved in sustainable management strategies such as tree nurseries.
Sustainable yield management in southern ocean fisheries
Accounts for 10% of worlds oceans. Limits for catch of individual species
Soufriere marine management area (SMMA)
Problems of water quality, depletion of fish stocks and degradation of beach landscapes. Now divided into zones each for different use. Led to a reduction in user conflicts
Masai Mara game reserve

CAMPFIRE, Zimbabwe
Project set up to develop and mange the sustainable use of natural resources in each communal area. Locals given responsibility.
St Lucia
has to conserve biodiversity as much of economy is tourism based
Brazil
rainforest reduced by 40% by 2030 for logging
Rhodedendron in Snowdonia
Brought to British garden but became invasive. Creates canopy which blocks light for other plants. Cost £10 million to remove with herbicide. 5,000 acres of Snowdonia covered
Lough Erne
Zebra mussels threatening ecosystems, eat algae which filters water. So native mussels dying out. No natural predators to keep them in check. Affecting fishing
BD in Oceans
Fish endangered due to unsustainable fishing practices like dynamite, pollution, global warming and fish trapped in nets
Now there’s fishing practices, fish farming and no take zones
Pandas in China
Ex-Situ, plan to create more in captivity then set free, 136 bred in Chengdu park. Half of their habitat has been destroyed in last 2 decades.
