The 2,350 acres at the Bull Run Mountains Natural Area Preserve are managed by the Virginia Oudoors Foundation (VOF). The site was designated as a Natural Area Preserve in 2002.
The entire site is managed as a living laboratory, outdoor classroom, and open-air museum. The southern portion is open for public use without a permit.
Researchers have access to the northern part. Occasionally it is open to the school groups and the general public for scheduled hikes and other special events. For example, studens in the Trout in the Classroom program release their fry at Jackson Hollow.1
