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

Atlanta Botanical Garden

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

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


Taxon Management Coordinator

Mark Mandica of Atlanta Botanical Garden

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?


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?

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).


If sufficient founders have not been collected, is there an ongoing search for additional founders?

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?



1.3 founders at ABG, 2.1 Founders sent to Mike Ready. 1.1 of founders breeding consistently at ABG, currently holding 0.0.18 F1s from this pair with more on the way. Update 01 Oct 2010: 2.2 Founders @ ABG (one specimen mis-sexed as Female) with 2.2.14 F1s and more on the way. 1.1.2 F1 transferred to Houston Zoo (already breeding) and 0.0.4 F1 transferred to St. Paul's Como Zoo in 2010. Update 22 Nov 2010: F2's produced at Houston Zoo. 0.0.4 F1 specimens to be transferred to Smithsonian National Zoological Park in Dec 2010. All F1 offspring currently in additional facilities outside of ABG are the result of breedings from just a single pair of founders. Breeding and oviposition observed in other 1.1 @ ABG and 2.1 @ Michael Ready's, but success very limited or non-existent with those animals. There are many more specimens being maintained @ EVACC in Panama, where they are on the F2 generation. Update 12/09/12. 2.2 Founders still remain at ABG in 2 breeding groups. Another f1 breeding group currently producing f2 offspring. Current inventory is 6.6.21 with 4 tadpoles still being reared. In 2012, we shipped 0.0.4 to Jen Stabile @ Albuquerque Bio Park and 0.0.4 to Bill Hughes @ TN Aquarium.
