Instruction Memorandum No. 2007-178
To: All SDs
From: Assistant Director, Renewable Resources and Planning
Subject: Escape Ramps in Water Developments DD: 10/15/2007Wildlife
Program Areas: Resource Improvement Projects – Water Developments
Purpose: To remind Field Offices that escape ramps shall be installed and maintained in water development projects on public lands.
Background: Water developments on public lands are designed to meet the needs of livestock, wild horses, and wildlife. To reduce the risk of wildlife fatalities, the Bureau of Land Management (BLM) has required installation of escape ramps in water developments for many years. (See BLM Manual Handbook H-1741-2 Water Developments 11/06/90 - copies can be ordered by sending an email to BLM_NCS_PMDS@blm.gov). The BLM policy has been to “Install escape ramps in open water troughs and tanks to protect water quality and to reduce wildlife loss.” (Section II-3b). Water developments that require escape ramps include all troughs, open spring boxes, open tanks, and guzzlers. The policy does not include dirt tanks, pit reservoirs, naturally occurring waters, or closed tanks not accessible to wildlife.
Escape ramp designs are limited only by the configuration of the water holding facility. Designs and installation specifications can be found in BLM Handbook 1741-2, “Water Developments,” November 1990; and Technical Bulletin 89-4 “Wildlife Watering and Escape Ramps on Livestock Water Developments: Suggestions and Recommendations,” Idaho State BLM Office, November 1989 (Update of Technical Note 305). An electronic version can be accessed at http://www.blm.gov/id/st/en/info/publications/technical_bulletins.html#1989. A more recent publication with suggestions on the installation of wildlife escape ramps is "Water for Wildlife - A Handbook for Ranchers and Range Managers", which can be accessed at http://www.batcon.org/news2/pdf/bciwaterforwildlife.pdf.
Policy/Action: It continues to be the policy of the BLM that water developments on public lands shall be equipped with escape ramps. This includes both existing and future water developments on public lands regardless of who constructed them, when they were constructed, or how the construction was authorized. All future water developments except for dirt tanks, pit reservoirs, naturally occurring waters, or closed tanks not accessible to wildlife, shall have escape ramps installed immediately upon completion of the project and before use. Authorization for the installation of new water developments must document who is responsible for maintaining the escape ramp.
While it may be impossible to prevent all wildlife fatalities associated with water developments, the BLM shall make a reasonable effort to ensure that these projects are as wildlife safe as possible.
Timeframe: Field Offices are encouraged to program their workload to ensure every water development on public land that requires escape ramps are equipped with a functioning escape ramp in a timely manner. A progress report is due back to the National Resource Improvement Coordinator in WO 220 by October 15, 2007, and every year thereafter until all water developments that require escape ramps have been inspected and escape ramps have been installed or repaired. Significant progress has been made during the last three years to inspect and maintain all wildlife escape ramps, however, an increased effort must be made to complete inspections on all remaining water development projects that require escape ramps by the end of Fiscal Year 2009.
Budget Impact: It is not known at this time exactly how many water developments are lacking escape ramps or have ramps that are in need of maintenance. Inspection of all water developments on public lands that require escape ramps will take a significant amount of time and fiscal resources. Maintaining, purchasing, or fabricating, and installing any missing or inadequate escape ramps will also take time. This activity has the potential to be expensive in both labor and operational dollars.
