Conservation and preservation You need to be able to:- Distinguish between conservation and preservation. Explain that conservation is a dynamic process involving management and reclamation. Discuss the economical, social and ethical reasons for conservation of biological resources. Use the Galapagos islands as an example of conservation in action

Conservation or preservation? Preservation is the protection of an area by restricting or banning human exploitation or contact – nature reserves/preserves/parks. Conservation is maintaining biodiversity but allowing sustainable production e.g. replanting mixed tree species after felling for timber. Management (grazing or water level control) and reclamation (preventing succession by draining) are part of conservation. Conservation is for economic (e.g. timber industry), social (recreation) and ethical (preventing species extinction) reasons. http://www.ace.mmu.ac.uk/eae/sustainability/Older/Conservation_and_Preservation.html

Where are they?

The Galapagos Islands, near Ecuador, south America

Charles Darwin He visited the Galapagos islands in 1835 and later wrote about the origin of species by natural selection

Allopatric and sympatric speciation of finches by natural selection into many different niches

Land iguana and Giant tortoise – 2 species endemic to the Galapagos islands

Wildlife on the Galapagos islands

Marine life near the Galapagos Islands

Why are the wild animals of The Galapagos Islands so unafraid of humans?

Threats to biodiversity on the Galapagos Islands Introduced species e.g. rats, cats, dogs, pigs, goats leading to competition for food, water and shelter plus habitat destruction Increase in human population leading to habitat destruction – coming for work or as tourists Over-exploitation of resources e.g. whales, seals, tortoises, sea cucumbers Result:- 25% of plant and 50% of vertebrate species endemic to the islands are now endangered

Conservation in the Galapagos Islands 1978 become world heritage site 1998 Galapagos marine reserve created Elimination of introduced species e.g. feral goats and pigs and prevent others arriving Captive breeding e.g. for giant tortoises All decisions include the concerns of local people and balance environmental, economic and social factors http://www.galapagos.org/2008 http://www.gct.org/
