Disturbed lands are much more vulnerable to threats such as erosion and nonnative species infestation. Loss of vegetative cover, often associated with disturbance, tends to lead to increased soil erosion. This, in turn, leads to the degradation of soil and water resources if not mitigated. Disturbance also tends to foster the increased establishment of invasive species, thereby degrading the overall community by displacing native flora and fauna.
Whenever possible the park uses natural buffer zones, native species plantings, and other preemptive management techniques to protect the disturbed site from these vulnerabilities. The park's management goal is to create a native species rich environment, and minimize the invasive threat to nearby undisturbed areas, while restoring important cultural landscapes to their historic conditions.
