Incorporating More Geological Themes into Ecotourism - A Basis for Mores Successful Business Cases

  1. 1. Government of Western Australia Department of Mines and PetroleumGovernment of Western Australia Department of Mines and PetroleumGovernment of Western Australia Department of Mines and Petroleum Rottnest Island geotourism Geosites, geoheritage & geotourism – the integration Ivor Roberts and Mike Freeman 2015 Global Eco Tourism Conference Rottnest Island 17th – 19th November
  2. 2. Government of Western Australia Department of Mines and PetroleumGovernment of Western Australia Department of Mines and PetroleumGovernment of Western Australia Department of Mines and Petroleum Ecotourism and Geotourism What is the relationship? • Ecotourism is sustainable tourism of natural areas What is the criteria that underpins the naturalness of natural areas? • The landforms, the soils, and these are all dependent on THE GEOLOGICAL ATTRIBUTES 2
  3. 3. Government of Western Australia Department of Mines and PetroleumGovernment of Western Australia Department of Mines and PetroleumGovernment of Western Australia Department of Mines and Petroleum Here I am, enjoying a crawl on the sea floor, living my life in peace • But, as the years pass, my arthritis becomes painful • My backache increases • And my aging muscles weaken My kids help at first, but then consign me to an old-folks home to see out my existence on this earthly planet. 3
  4. 4. Government of Western Australia Department of Mines and PetroleumGovernment of Western Australia Department of Mines and PetroleumGovernment of Western Australia Department of Mines and Petroleum My time has come and I pass away R. I. P. • The Old Folk’s management is tired of taking care and throw me out of the door • Passing waves and unceasing currents wash me into shallow waters • Towards the coastline • Into the turmoil of the raging surf and breaking waves 4
  5. 5. Government of Western Australia Department of Mines and PetroleumGovernment of Western Australia Department of Mines and PetroleumGovernment of Western Australia Department of Mines and Petroleum My epitaph is a sorry story • My remains are broken, smashed against other remains as we are thrown around by the waves • Pulverised, becoming mere sand grains but, not ordinary sand but LIMESAND Sand grains are washed onto the beach 5
  6. 6. Government of Western Australia Department of Mines and PetroleumGovernment of Western Australia Department of Mines and PetroleumGovernment of Western Australia Department of Mines and Petroleum My sand grains, in company with billions of other grains, are blown up the beach, into a ‘frontal dune’ My sand grains, plus neighbours, become sand dunes 6
  7. 7. Government of Western Australia Department of Mines and PetroleumGovernment of Western Australia Department of Mines and PetroleumGovernment of Western Australia Department of Mines and Petroleum But my remains are changed – through the magic of chemistry • Winter rains come • Rainwater sinks into the limesand dunes • Water dissolves lime, but then precipitates it when summer heat dries out the dune • Lime cements the grains together • Limesand becomes limestone 7
  8. 8. Government of Western Australia Department of Mines and PetroleumGovernment of Western Australia Department of Mines and PetroleumGovernment of Western Australia Department of Mines and Petroleum The geological underpinnings of Rottnest Island • 18 000 years ago sea levels were 130 metres lower • High coastal dunes formed linear ridges • As icecaps melted, the sea rose and by 7000 years ago reached near the present level • Many coastal limestone dunes became offshore reefs • Rottnest became an island, linked by reefs to Garden Island 8

  21. 21. Government of Western Australia Department of Mines and PetroleumGovernment of Western Australia Department of Mines and PetroleumGovernment of Western Australia Department of Mines and Petroleum • The idea that we are standing on non-descript and uniform ground is wrong. The rocks beneath our feet represents a catalogue of changes that the Earth has experienced. • The ground we stand on helps to explain why the geology we find around us today is how it is, why we have different landscapes, why plants and animals are not all the same and for the activities of our ancestors and even ourselves. 21

Government of Western Australia Department of Mines and PetroleumGovernment of Western Australia Department of Mines and PetroleumGovernment of Western Australia Department of Mines and Petroleum Conclusion • At Rottnest Island we have geological sites of importance • These are valuable for: 1. Scenic attractions 2. Sites of general interest 3. Sites of learning for the general public & the specialised (scientific) community • So, as we go forward with a desire to show off our World, remember the importance of geology 24
