The Future is Ours to Pass Along...

The Williamson County Conservation Foundation (WCCF) was established in December 2002 to provide for conservation of endangered species in Williamson County while helping to promote responsible development.

Williamson County is one of the fastest growing counties in the country. Rapid growth necessitates a regional approach to balancing development needs with the needs for conservation.

Texas Conservation Symposium 2019

The 5th Annual Texas Conservation Symposium will be January 10 and January 11, 2019 with a half-day program on Thursday and a full day's program on Friday.

A jointly sponsored event by Southwestern University and the Williamson County Conservation Foundation, once again registration, breaks and the Friday lunch will be provided thanks to the generous support of our many sponsors.

Also this year will be a Thursday evening social (details to come).

To register - which helps us get a count for breaks and lunch - please go to http://www.wilco.org/txconservationregistration.

ATTENTION! Golden-cheeked warbler participation fees - Thursday, October 20, 2016

The Williamson County Conservation Foundation Regional Habitat Conservation Plan, Section 6.2.2, Golden-cheeked warbler, contains the following language:

“The participation fee for take of golden-cheeked warbler habitat is $7,000/acre in the first year fees are charged and increasing by an estimated $500/acre each year as long as the mitigation credits last.” 

At its December 8, 2010 regularly scheduled meeting, the WCCF board authorized the WCCF management to make adjustments, as needed and based on recommendations from the Adaptive Management Committee, to Golden-cheeked warbler participation fees as follows: tracts smaller than 200 acres - $9000 per acre; 200 to 700 acres - $7500 per acre and greater than 700 acres - $7000 per acre.

The revised Golden-cheeked warbler participation fees became effective September 1, 2014.

Learning about Salamanders

The US Fish and Wildlife Service (USFWS) issued its final listing rule on the Georgetown and Salado salamanders on February 22, 2014, placing both species in the "threatened" category. In addition the US Fish and Wildlife Service published a proposed 4(d) Special Rule. Section 4(d) of the ESA allows the USFWS to establish special regulations for threatened (not endangered) species, subspecies, and Distinct Population Segments. These "4(d) rules" take the place of the normal protections of the Endangered Species Act and may either increase or decrease the ESA's normal protections. The ESA specifies that 4(d) rules must be "necessary and advisable to provide for the conservation of such species."

The proposed 4(d) rule is expected to follow exactly (or very closely) the City of Georgetown water quality ordinance approved by the City on 12/20/13. For information on how to follow the ordinance guidelines call the City of Georgetown City Code and Development Department or contact the WCCF.

Our Work

WCCF has established several important cave preserves. Four have been recognized as Karst Fauna Areas under the Williamson County Habitat Conservation Plan.

  • Twin Spring Preserve - karst invertebrates, Golden cheeked warbler and Georgetown salamander
  • Cobb's Cavern Preserve - karst invertebrates
  • Priscilla's Well Preserve - karst invertebrates
  • Karankawa Preserve - karst invertebrates

Two preserves form natural areas within Williamson County’s Southwest Regional Park - Millenium Preserve and Wilco Preserve. Two preserves in the southern part of the county provide additional karst habitat - Beck Preserve and Chaos Cave Preserve.  Also the WCCF manages several smaller preserve areas in various parts of the county. Most provide habitat for karst invertebrates.

To inquire about Williamson County's site-specific Leave No Trace training for preserve areas please send an email to [email protected]. Now only the Twin Springs Preserve is available for public access but plans are to provide access to the greatest extent possible using a "Leave No Trace for Williamson County Preserves" training.

How to Get Involved
Long term management of the Regional Habitat Conservation Plan provides numerous opportunities for public involvement, and the WCCF Board encourages the public to become actively involved in this process.

Twin Springs Preserve has marked pathways encompassing approximately 3.5 miles of natural trails through the county’s Twin Springs Preserve which is managed by the Williamson County Conservation Foundation . The preserve may be reached from the Russell Park trail-head for the Goodwater Trail, approximately 3.25 miles from the Russell Park trail-head to the Twin Springs loop.

Also, the WCCF recently added a small (about six cars) parking area off of County Road 262. A kiosk with preserve information leads to the pathway loop.


The Twin Springs Preserve provides habitat for endangered and threatened species.  Access is by permit only. Permits are free but must be obtained by attending an approved training session, “Leave No Trace Principles for Williamson County Preserves.” Information on training sessions may be obtained by calling 512/943-1921 or by sending an email to [email protected].
