Threatened & Endangered Species
Overview
The Threatened & Endangered Species Department manages the Edwards Aquifer Habitat Conservation Plan (EAHCP) which defines how we protect federally listed species that live in the Edwards Aquifer and the Comal and San Marcos springs systems. Our program’s Incidental Take Permit (ITP) was issued by the USFWS to the Edwards Aquifer Authority, City of San Marcos, City of New Braunfels, Texas State University, and the City of San Antonio acting by and through the San Antonio Water System (collectively known as the EAHCP Permittees) to protect federally listed species from specific covered activities listed in section L of the ITP. The EAHCP implements the following conservation measures in accordance with the program’s Funding and Management Agreement to protect the Covered Species and their habitat.
Conservation Measures
Habitat Protection Measures
Minimization, mitigation and avoidance conservation measures implemented in the Comal and San Marcos springs systems, including (but not limited to) aquatic habitat restoration, riparian habitat restoration, impervious cover/water quality protection, litter collection, floating vegetation management, non-native animal species control, and aquatic recreation management.
Flow Protection Measures
Conservation measures that protect and maintain springflow in the Comal and San Marcos springs systems including the Regional Water Conservation Program, Voluntary Irrigation Suspension Program Option, Stage V Critical Period Management and use of SAWS Aquifer Storage and Recovery program.
Supporting Measures
Measures that support, enhance, or evaluate implementation of the EAHCP including applied research, biological monitoring, expanded water quality monitoring, and refugia centers.
