Caves and other karst resources on properties owned or leased by the department of natural resources are experiencing increasing recreational use. Increased usage places pressure on karst resources and results in potential threats to public safety. The purpose of this information bulletin is to provide a uniform policy for the management of caves and karst resources located on department of natural resources properties. The information bulletin is supportive of 312 IAC 8.
The policy is more particularly written to address these primary concerns of karst management as identified by a broad-based task force of users and managers:
This information bulletin was developed over an 18-month period by the cave task force. The task force was made up of 15 individuals within and outside the department. Included were representatives from the Indiana State Police, the Indiana Department of Natural Resources (including the Division of State Parks and Reservoirs, Division of Nature Preserves, Division of Fish and Wildlife, Division of Forestry, Division of Historic Preservation and Archaeology, and the Division of Law Enforcement), the Harrison County Hospital, the Indiana Karst Conservancy, the Bloomington Grotto, and the U.S. Forest Service. Subsequently, the task force met to develop a separate document, Caves and Karst Management Guidelines (November 16, 1998).
The cave task force developed this information bulletin to assist in the management and enhancement of cave and karst resources on properties owned by the department. Included among these resources are geological, historical, archaeological, biological, recreational, and similar values. The developmental goal was to maintain these resources for public benefit while allowing the recreational use of caves.
As used in this information bulletin,
"Caving" means the exploration of undeveloped or wild caves.
"Karst" means terrain, generally underlain by limestone, in which the topography is chiefly formed by the dissolving of rock, and is commonly characterized by closed depressions, underground drainage, and caves.
"Show cave" means any naturally occurring void, cavity, recess or system of interconnected passages which occur beneath the surface of the earth or within a cliff or ledge that has been altered from its natural state for commercial viewing.
"Wild cave" means any naturally occurring void, cavity, recess, or system of interconnected passages which occur beneath the surface of the earth or within a cliff or ledge, whether or not it has an identifiable entrance. To be considered a "wild cave," the cave cannot have been significantly altered or enhanced from its natural state for commercial viewing. The term includes any natural pit, sinkhole, or other feature of a cave.
The natural resources commission approves the following policy statements to assist in cave and karst management on properties of the department of natural resources:
A. Resource Identification: The department shall develop a strategy to survey and identify significant karst features on properties owned or leased by the department. To the extent allowed by law, the department shall limit or restrict access to information regarding the location of wild caves and sensitive features in order to protect these resources.
B. Resource Protection:
1. Cave Entrance Alteration: The department shall attempt to keep wild cave entrances in a natural state. The use of explosives or digging to modify entrances is prohibited except for emergencies such as cave rescues or critical management situations. Emergency actions shall be approved by the director of the department or a designee of the director.
2. Posting and Signing: The department shall not attract attention to the location of a wild cave entrance by posting signs or other markers, except for a show cave or for another specific management purposes. Signs prohibiting entry due to sensitive resources should be visible for a limited distance outside the entrance to a cave.
3. Cave Gating: Caves shall not be gated except to protect sensitive resources or if there is a history of injury or deaths resulting from open access to a particular cave. The decision to gate a cave shall be made through an interdisciplinary team assessment to prevent unwarranted or improperly designed gates.
4. Erosion and Pollution Control: Activities on properties owned or leased by the department that cause direct subsurface impacts to cave passages and biota are prohibited without written approval of the commission. These activities include drilling, excavation, mining, and similar activities. Surface and subsurface activities that may impact subsurface karst resources shall be appropriately designed and conducted to minimize impacts to karst systems.
5. Land Acquisition: The department shall attempt to acquire private property from willing sellers if the property will enhance the protection of karst resources on properties owned or leased by the department.
6. Protective Status Designation: The department shall evaluate any area that includes an exceptional cave and consider the area for
7. Destruction of Cave Resources: Except as authorized by an appropriate license, the destruction, removal, mutilation, or defacing of any cave resource is a violation of 312 IAC 8-2-10.
C. Karst and Cave Research: An individual conducting scientific research on property owned or licensed by the department must obtain all applicable licenses. These licenses do not supersede any federal licenses needed to gather data on federally protected species. A research license from the administering division also serves as a caving license for a researcher.
D. Recreation and User Management:
2. Access to Wild Caves: Access to wild caves is authorized only by an annual or daily license. This restriction does not apply to guided cave tours or special events approved by the department. Fees for licenses shall be prescribed or approved by the commission.
3. Access to Caves with Significant Resources: Access to caves containing sensitive or especially significant resources, or to those posing significant safety hazards, shall be regulated at the discretion of the director of the department of the director's designee.
4. Camping Prohibition: Camping and overnight stays in caves are prohibited without prior written approval from the property manager. This approval shall ordinarily be granted only for educational or scientific purposes.
5. Statutory Cave Protection: A person entering a cave must comply with IC 35-43-1-3 (sometimes called the "Indiana State Cave Law").
F. Karst and Cave Administration:
I. Guidelines Overview
A. Existing Conditions: Most caves and karst features found on IDNR properties are managed using a variety of methods, often based on the individual property manager or Division. At present, there are few specific management plans written for caves or karst features on IDNR properties.
B. Cave Numbers: There is often little or no definitive information on the names, numbers, and exact locations of caves on IDNR properties. We have limited information on size, topography, drainage, or degree of difficulty of most caves on IDNR lands.
C. Threats to Karst and Cave Features: The Caves Task Force has identified eight common threats to karst and cave features on IDNR properties:
A. Protection and preservation of caves and associated drainage areas should be a priority.
B. Caves should be managed to protect their natural state, and to perpetuate their natural ecological processes, including the interactions of cave and surface biological communities.
C. Maintain and enhance the water quality of cave and karst spring systems and prevent subsurface disturbances which may affect water quality.
III. Management Action Plan: The Caves Task Force has identified the following action items as the necessary steps to achieving Management Goals:
A. Resource Identification: In order to establish a process to survey and identify cave and karst features on its properties, the IDNR should:
2. Develop an MOU with the ICS and the IKC to establish guidelines for the use and ownership of cave data on IDNR properties.
3. Treat karst/cave data as sensitive information.
4. Survey information should include the cave's name, location, a brief description, cave map, topographic overlay, drainage/recharge area, significant features/values, and special hazards.
5. Develop an MOU with other appropriate [entities] to evaluate and address environmental impacts.
3. Management Activities:
2. The researcher must have the necessary collecting permit from the Division of Fish & Wildlife.
3. The researcher must have the necessary permit for listed species from the U.S. Fish & Wildlife Service.
4. Additional permits may need to be issued from Nature Preserves and Historic Preservation if the study area falls in a Nature Preserve or archeological site.
5. Final results/documentation must be distributed to the proper division and property. The researcher is also responsible for sharing their results with the other affected divisions.
3. Each caver using noncommercial show caves on IDNR properties must carry the minimum acceptable equipment for that particular cave.
2. Each member of the caving party must have a daily or annual caving permit.
