Geography Resilience and Vulnerability

“Explain the impact of natural stress’s and human induced modifications on the vulnerability and resilience of two ecosystem you have studied”
Ecosystems are highly fragile and any slight change either natural or human induced can effect it’s ability to resist the effects of these changes. This is also known as resilience, the more resilient an ecosystem is the more it can withstand, high resilience is common with large ecosystems as they have a higher range of diversity and life.
Natural disasters have a immediate and devastating impact on any ecosystem and being on the ocean the Port Stephens Coastal Dunes have the ability to receive both land and ocean natural disasters. Strong wave action has the ability to remove tonnes of sand within hours disrupting plant life and therefore destroying natural habitats and animal life. Without sand the stability of plants and natural habitats is largely effected as they are unable to begin to rebuild slowly and gradually.
Port Stephens Coastal Dunes is a highly resilient ecosystem as it stretches for kilometers along the coast of Australia. However this large ecosystem is still strongly affected by both natural stresses and human- induced modification.
Humans have the ability to make extensive changes among any ecosystem and this is likely to result in any ecosystem’s inability to demonstrate a strong show of resilience. Port Stephen’s Coastal Dunes is in close proximity to many areas of housing and is part of a popular tourism area. With this excess of people visiting the area it can have a significant effect on the Dunes ability to bounce back from any human induced modifications. Urban, industrial and agricultural land uses destroy natural ecosystems. Oceans, rivers and atmospheres have become dumping grounds for pollutants all along the Port Stephens Coastal Dunes.
The alpine ecosystem is another ecosystem that has been strongly impacted by natural stresses and human- induced modifications. The organisms living in...
