New York Restricts Access to Cave Hibernation Sites

Live Poll

Should local authorities restrict public access to caves to protect hibernating bat populations?

The New York State Department of Environmental Conservation has restricted access to caves and mines to prevent the disturbance of hibernating bats. Human presence can cause bats to deplete essential fat reserves, threatening their survival throughout the winter season.

Why it matters

Disturbing bats in their hibernacula forces them to burn energy they need to survive until spring, which is critical as populations struggle to recover from disease. These sites provide stable temperatures that act as essential life support for the six native species that remain in the state.

New York is home to nine bat species, including six that hibernate in caves and three that migrate. White-nose syndrome, which arrived in 2006, has been responsible for the loss of more than 90% of bats at affected hibernation sites.

The players

New York State Department of Environmental Conservation

This state agency is responsible for the management and protection of natural resources across New York.

The details

Visitors must obey all posted restrictions at caves and mines to remain compliant with state law. Anyone who inadvertently encounters hibernating bats is instructed to leave the area immediately and quietly to minimize disruption.

October 1 to April 30 is the period when entering hibernation sites may lead to prosecution.
October 24, 2026, marked the start of Bat Week.
November 1 to March 31 is the recommended tree removal window in most of New York.
December 1 to February 28 is the recommended tree removal window for Suffolk County.

The Big Picture

The current cave closure order follows a pattern set by the 2006 arrival of white-nose syndrome in New York, which decimated regional populations. This measure reflects a shift in conservation strategy from reactive monitoring to preventative protection for struggling species.

Hikers and spelunkers must verify local cave status before planning trips, as unauthorized entry into restricted sites can result in prosecution. Following these guidelines helps maintain the necessary silence and stable environment required for bats to successfully overwinter.

The takeaway

Winter is a high-stakes season for local wildlife, and even unintentional disturbances can have dire consequences for recovering bat populations. Residents should respect posted signage at all cave entrances to ensure these animals reach the spring season safely.
