Exclosure

[13] In the Tigray Region, in Ethiopia, several exclosures are managed by the EthioTrees project.

[15] Exclosures are sometimes constructed by government agencies that manage livestock use on public lands—a practice in which private owners of cattle pay, though often only a nominal sum, for the right to graze their livestock on the public lands.

[citation needed] One purpose of the exclosure is to determine how the area would develop (in biodiversity, vegetation height, ecological characteristics, etc.)

[citation needed] Another purpose is to demarcate an area safe for humans by excluding potentially deadly animals.

Another example is at wild animal preserves which provide fenced in areas for humans to safely watch lions, tigers, or other large predators.
