Wildlife preserves can be thought of as islands containing populations that are isolated due to the surrounding human-altered landscape. conservation biologists often strive to preserve large areas based partially on the predictions of island biogeography. however, a single large area is more vulnerable to negative effects from than are multiple small areas.

However, a single large area is more vulnerable to negative effects from natural or mand made disasters than are multiple small areas.

Explanation:

A single large area is more vulnerable because they contained more species than multiple small areas. Therefor natural or mand made disasters will have more impact where we have more species that can be affected. The model of island biogeography states this.
