Progress of the Lithobates chiricahuensis program
at Fort Worth Zoo


Lithobates chiricahuensis

Common Name(s)

Chiricahua Leopard Frog;Rana-de Chiricahua

Region where program is based

North America

Country where program is based

United States

The authority that recommended this species for an ex situ program

Conservation Needs Assessment Workshop

Has a genetic analysis been performed on wild populations to define the target taxon, i.e., verify that single, viable Evolutionarily Significant Units (ESU's) that are managed as separate populations, are not confounded by cryptic species or polymorphisms?


Name of the institution managing the ex situ population

Fort Worth Zoo

Year the program started


Is at least some portion of the captive population maintained in range country?


Are sufficient resources available to manage the ex situ population?


Are adequate numbers of skilled staff available with the appropriate ex situ amphibian experience?


Is sufficient space available for the required population size?


Additional Support required

Sufficient resources are available at the Fort Worth Zoo, however, additional resources are needed for partners. The captive program should expand to support reintroduction efforts. Additional staff and resources needed for in situ management, invasive species control and monitoring efforts

Has a Taxon Management Coordinator for the ex situ population been appointed?


Taxon Management Coordinator

Diane Barber of Fort Worth Zoo

Has a Taxon Management Group or Recovery Team been established?


Has a Taxon Management Plan, Recovery Plan or Species Action Statement been written?


Web link to Taxon Management Plan

Have Husbandry Guidelines been written?

In preparation

Web link to Husbandry Management Guidelines

Have any knowledge gaps in the species biology or in their interaction with potential threats been identified that could benefit from research using the ex situ population?


List of knowledge gaps

Nutritional, invasive species control, reproduction, disease, survivorship, population density.

Have founder needs been calculated using the AArk Amphibian Population Management Guidelines ?


Have sufficient potential founders been collected? ( AArk Amphibian Population Management Guidelines recommends a minimum of 20 pairs of found animals).


Is the ex situ population managed by nationals from the range country?


What tools are used to maximize retention of genetic diversity?


Has the population produced viable offspring?


Have the first generation captive-bred animals bred successfully?


Is the ex situ population housed in permanent isolation from other populations occurring outside its range?


Is work being supported to study and mitigate threats to the species in the wild, either by the institution or by a regional wildlife agency?


Have captive-bred or captive-reared animals been released into the wild?


If releases were undertaken, have disease screening protocols or veterinary health checks been conducted prior to releases to the wild?


Is follow-up work being carried out to monitor progress of the released animals?


Is the taxon again secure in the wild, even if it might still require some ongoing in situ management? i.e. has the need for a captive assurance population been obviated such that we can call this a successfully terminated captive rescue program?



2013: In 2013, 525 tadpoles hatched at the Zoo were sent to New Mexico for repatriation to their native habitat. 2014: In 2014, 277 Zoo-hatched tadpoles were sent to New Mexico for repatriation efforts in collaboration with the US Fish & Wildlife Service (USFWS) and the New Mexico Department of Game and Fish. 2015: In 2015, 262 hatched tadpoles at the Zoo were sent to New Mexico for repatriation efforts in collaboration with the US Fish and Wildlife Service, and the New Mexico Department of Game and Fish.
