Williamson County Regional Habitat
Conservation Plan
The Williamson County Conservation Foundation (WCCF)
was established as a pro-active measure to further the
conservation of endangered species in Williamson County
while helping to further responsible development.
Williamson County Regional Habitat
Conservation Plan
The US Fish and Wildlife Service issued
Williamson County’s 10 (a) Permit on
October 21, 2008.
The Most Ecologically Diverse
State in the Nation
The #1 threat to wildlife today...
Texas now loses more than 1 acre of habitat
every 7 minutes, 24 hours a day, 365 days a year
Purpose and Need
Need for the Action
• Population expected to more than triple
over the next 30 years.
• Development activities could result in
the take of listed species
WHO CAN BENEFIT FROM THE RHCP?
Governmental entities:
Cities and towns
School districts
Political subdivisions (MUDs, PIDs)
State
Developers
Landowners
Citizens
The Williamson County RHCP
•
•
•
•
RHCP to cover take of warbler, vireo, and two listed karst species
30 year term
Completely voluntary participation
Over the next 30 years, Mitigation efforts would include:
– Estimated 700+ acres of karst preserves
– Approximately 6,000 acres of mitigation on Golden Cheeked
Warbler
– Restoration and/or enhancement of Black-capped vireo habitat on
a rolling basis
– 5-year study for the Georgetown salamander
– Public outreach and endowment fund
How does the Williamson County Regional Habitat Conservation Plan
Benefit the Stakeholders of the County?
By:
 Significantly reducing participant’s time and expense for ESA compliance
compared to individual permits
 Coordinating and accelerating endangered species conservation efforts in the
County
 Precluding future listing of additional species
 Providing for and preserving some of the natural character of Williamson County
 Providing additional recreational and natural assets to be enjoyed
PERMIT AREA
All of Williamson County
 Primary focus is the Karst
Zone, which provides
habitat for the karst
invertebrates included in
the RHCP
 Most habitat for the karst
invertebrates and
endangered birds is west of
I-35

The Black-capped Vireo
Historical records show that
this bird once nested
throughout Central Texas and
as far as Oklahoma and central
Kansas.
Today, central Texas provides
habitat for remaining
populations of this species.
Habitat loss, cowbird
parasitism, and predation are
the primary threats to this
native songbird.

 Objective: Preclude need to list
No take under the RHCP
 Commit funding for a five year
study to gather additional
information on the species.
 At the end of year 2 begin
preparation of appropriate
conservation strategy.
