exclosure

"There seems to be a lot of stuff coming up inside the exclosure," Ms. Preston said.

Exclosures are not always used as they occasionally draw more attention to the nest than would occur without the exclosure.

A deer exclosure was built to demonstrate the effects of grazing pressure from the deer.

In July 2006, a viewing tower was constructed near a northern rata grove in the southern exclosure.

One purpose of the exclosure is to determine how the area would develop (in biodiversity, vegetation height, ecological characteristics, etc.) if grazing were not conducted.

A bird exclosure was built here in the mid 1990s to protect an area of marginal vegetation, preventing water plants being damaged by coots.

This method also has drawbacks, as scavengers such as hyenas are capable of infiltrating almost any exclosure.

The history of the Salt Cabin Park Exclosure area consists of grazing that started in the late 1800s.

The Kenya Long-term Exclosure Experiment - An exclosure experiment in Africa with both livestock and wildlife.

"It's the same sort of seedlings as on the outside - maple and tulip trees and so forth - but they're just much more numerous inside the exclosure, and they're healthier, not browsed so heavily."

In certain situations, predator exclosure structures (allowing adult birds to freely move in and out of the nest site to brood/provision chicks, but preventing mammalian predators from attacking the eggs, chicks, or adults) have proven successful.

An exclosure, in an area being used extensively for grazing, is a limited area from which unwanted animals, for example browsing animals, such as domestic cattle or wildlife, such as deer, are excluded by fencing or other means.
