In 1992, four endangered species habitat and management zones in the Austin region were delineated for the USFWS by George Veni and Associates. Those zones were defined as:

Zone 1: areas known to contain endangered cave faunaZone 2: areas having a high probability of suitable habitat for endangered or other endemic invertebrate cave fauna (refined now to only endangered cave fauna)Zone 3: areas that probably do not contain endangered cave fauna; andZone 4: areas which do not contain endangered cave fauna.Zone boundaries were updated in 2007 to reflect more recent studies of cave and karst development and the most current biological information available on the distribution of listed and non-listed troglobite species. For more information on listed karst invertebrates in Texas, see https://www.fws.gov/southwest/es/AustinTexas/ESA_Sp_KarstInverts.html.

The Williamson Act is a State program that preserves agricultural and other open space lands. In exchange for committing land to agricultural uses for at least 20 years, landowners receive significant tax breaks. In Sacramento County the Office of Planning and Environmental Review initiates and processes applications to establish Williamson Act land conservation agreements. The same department processes applications to "non-renew" agreements. The County Assessor's Office is responsible for calculating and assessing tax reductions related to the Williamson Act contracts.Agricultural Land Preservation

These regions are delineated based on geologic continuity, hydrology, and the distribution of 38 rare troglobitic species. For more information on listed karst invertebrates in Texas, see https://www.fws.gov/southwest/es/AustinTexas/ESA_Sp_KarstInverts.html.
