<span>Conservation strategies that set aside ecosystems for preservation </span>are the best way to preserve an area's diversity.
The World Wildlife Fund says that the conservation strategies that focus on ecosystems for preservation have an impact on preserving and area's diversity because it is a complete, healthy ecosystem, filled with all that is part of it, that will maintain the diversity of its area - for example, if a species of a tree from a certain ecosystem was to be extinct, not only that species would disappear, reducing already by itself the diversity of the area, but it would also affect other species taking them probably also to eventual extinction, once more reducing the diversity of the area.
