NSS Nature Preserves
The NSS owns 21 cave preserves and manages 3 preserves owned by others through a Memo of Understanding. Learn more about individual preserves below.
Protecting The Underground
The NSS began over 80 years ago as a collective of individuals interested in caves and caving. From the beginning, we recognized the need to protect the fragile and timeless environments above and below ground. Conservation has always been a prime tenet of the NSS's foundations.
Today we fulfill that mission by managing 24 preserves. These unique underground places are protected for future generations.
Each preserve has its own management plan that lays out policies and access for recreation or scientific research. Contact the preserve manager for a copy of the detailed management plan.
