Ecosystems At Risk Essay

1097 words - 5 pages

A management strategy is ‘a plan of attack’; a response to the problem or concern at hand.
Management strategies are needed to protect ecosystems (including those used by indigenous peoples) at a local, national, regional, continental and global level. They are used to preserve and conserve ecosystems at risk and recognise the need to manage whole ecosystems. This may involve strategies that range from total preservation to sustainable development.
Management strategies over time have changed in various ways to suit the way the population has developed. Changes in ecosystem management strategies can be caused by technological advances, changes in the ecosystem itself, and economic and ...view middle of the document...

These may have all had short term impacts on the surroundings but the Aboriginals were often changing camp sites so the previous sites had time to be renewed and flourish with growth.
Burning may have caused change to Australia’s vegetation, and the hunting may have contributed to the extinction of some species of animals, but these two factors are minor effects in relation to widespread degradation caused by farming, mining, and land and industrial uses.
An example of traditional management is the Indigenous Australians is putting back the yams that they had dug up back into their holes so that they would regenerate. They also done this with plants and flowers that they had taken, artificially fertilising them to help them grow.

Management of the land was mainly focused on the conservation of species within their living areas. Strategies include:
• Restrictions to species caught
• Closed seasons
• Designated areas for individuals and groups
• Limits to population growth
• Sustainable methods of hunting
• Leadership according to age
Different groups of indigenous people have their own definitions of ecosystem management raised through their culture. Experiences are passed on through the generations of the tribes. This is done through laws, codes of conduct, customs, rituals, ceremonies, stories and teachings. Natives’ being separated from their land means that the knowledge has been lost and management has ceased. The land is dependent on the ability of these peoples to use the land again.

The Aboriginal Natural Resources and Environment Council help to advise the Australian government on land and water issues. This is how aboriginal ecological information can be used to hrlp develop and form the best and most reliable form of sustainable ecosystem management.

Contemporary Management Strategies
In recent times, there have been newer methods of management strategies that have been formed, rather than the traditional management strategies that were used by the Aboriginals years ago. Preservation, utilisation and exploitation are all ways in which management is approached. Preservation refers to the protection of a species or a habitat, utilisation involving the replacement of an ecosystem with a human made environment capable of a sustainable yield, and exploitation being when an ecosystem’s resources are used irrespective of the ecological consequences.
Contemporary management strategies are always evolving as our knowledge of ecosystems grow, also using an increased use of traditional management...
