Species of Common Conservation Concern Working Table

Species of common conservation concern under the Trilateral Committee include, but are not limited to cross-border species (species that move across borders or populations that are shared among the countries).

Mission Statement"To promote cooperative, comprehensive strategies and implementation of trilateral actions for the conservation of native wild plants and animals of concern and control of invasive species across North America."

This table facilitates dialogue between North American resource managers, allowing them to learn from each other's experience.  This is enriched by the participation of state natural resource agencies and non-governmental organizations. This table encourages, supports, facilitates and endorses activities for the conservation of native species and habitats through collaborative, community-based projects for several species, often providing income for local residents while protecting species at risk.


 Trilateral Island Initiative

  • To mitigate nest site inundation due to impending sea level rise, federal and non-profit partners translocated 21 fertile eggs and 12 chicks of Black-footed Albatross from the United States’ Midway Atoll to Mexico’s Guadalupe Island in 2021.
  • In 2018, workshops were held in California to advance island plant conservation and biosecurity. 
  • Facilitated the recovery of Baja California Pacific islands seabirds including populations of the Ashy Storm-Petrel, Scripps’s Murrelet, and Cassin’s Auklet by reestablishing 21 extirpated colonies, starting 11 new colonies, and improving breeding success.
  • To date, 27 black-footed albatross healthy chicks (18 hatched and 9 imported) are successfully growing in Isla Guadalupe.

North American Bat Conservation Alliance

  • As part of ongoing prioritization and completion of surveys for bats affected by the widespread fungal disease white-nose syndrome, United States and Canadian partners consolidated and shared data at www.whitenosesyndrome.org
  • As of March 2021, more than 60 bat hibernacula in Mexico have been identified and found to be free of the widespread pathogenic fungus that causes white-nose syndrome in bats. 
  • Published the southern-most record of a hibernating hoary bat, found in Mexico City. 

Mexican wolf recovery cooperation

  • From 2019 to present, the USFWS, SEMARNAT, CONANP, AZGFD, NMDGF, and the Mexican wolf Species Survival Plan (SSP) continued their collaboration on the release of wolves in the U.S. and Mexico, including translocating four wild packs from the United States to Mexico.
  • After nearly fifty years of collaboration, México and the U.S. continue working together to manage the binational Mexican wolf Species Survival Plan (SSP) captive breeding program to provide Mexican wolves for release in both countries.
  • As part of the implementation of the Mexican wolf recovery plan, United States and Mexican federal and state partners are prepared to sign a formal letter of intent to ensure the success of the species and its self-sustainability within the ecosystem.
  • In October 2021 Mexico will be celebrating its 10th anniversary of the Mexican wolf reintroduction program in Mexico. 
  • As a result of this joint work, in 2019 the Mexican wolf was recategorized in Mexico’s Endangered Species Act (NOM-059) changing its status from “possibly extinct” to “endangered”.


  • Parks Canada and the Wildlife Conservation Society are studying genetic diversity and population viability of Canadian bison herds to help inform management decisions that will maximize the conservation potential of bison at the national and continental levels. The effort is similar to one the US Department of the Interior completed in 2020 and will allow for development of a continental-level management strategy for bison.
  • As a result of the 23 individuals donated by the U.S. government, in 2019 Mexico initiated the establishment of its second herd in the State of Coahuila, following the first one from established in Chihuahua in 2009.
  • Mexico established a bison recovery group for Mexico and held virtual workshop to determine how to progress with the implementation of the Mexican Recovery Plan for the Bison (PACE).

California Condor

  • In 2020, the USFWS, CONANP, and the San Diego Zoo signed a joint Work Plan on Conservation Research and Information Exchange aiming to identify limitations on California condor population size and recovery in Baja California Mexico and the US. The group is conducting collaborative research to identify and mitigate threats to the species and make management recommendations. 
  • The U.S.-Mexico California Condor team continue working with the Chapultepec Zoo on the reproduction, rearing, and release of chicks as part of Mexico's captive breeding program. To date, nine chicks have been born in captivity from which two have been released in San Pedro Martir, three will be part of Chapultepec Zoo's educational exhibit, and the remaining four (born in 2019 and 2021) will be released soon. 
  • The Zacango Zoo has been formally accepted as a new partner to the U.S.-Mexico California Condor Recovery Program and is currently expected to receive one bird from Santa Barbara Zoo, which will be used for exhibit and educational purposes.
