Preservation
Preservation is the protection of an area or ecosystem by keeping it in its present, untouched state, with little or no human interference. Human use of the area is restricted or banned.
The difference between the two approaches is important:
• Conservation involves active management and allows sustainable use of resources by humans; it may change or restore a habitat.
• Preservation aims to leave the ecosystem as it is; resources are not harvested, and access is usually limited to scientific research or strictly controlled visits.
