Stewardship and Ecological Threats

The plants, animals, physical setting, and natural processes of a natural community are interrelated and interdependent. A threat to any part is a threat to the whole.

For example, if the deer population is too large, and they eat almost all the oak seedlings, there may not be enough acorns in the coming decades to support as much wildlife. Or if an invasive vine such as Japanese honeysuckle or English ivy covers mature trees, cavity nesters such as woodpeckers and owls may not be able to nest in those trees.

Learn more about common ecological threats and how park staff, government agencies, and volunteers are addressing them.
