The decision to designate the black lion tamarin population of the Caetetus Ecological Station (FF\/SP) as a priority was made during the Workshop for the Implementation of the Black Lion Tamarin Population Management Program, which brought together around 20 specialists at the headquarters of IP\u00ca \u2013 Institute for Ecological Research, in Nazar\u00e9 Paulista (SP), in March (11\u201313). The workshop had the following objectives: to assess the current status of black lion tamarin populations based on updated data; to define priority population management strategies for the species conservation; and to conduct the annual monitoring of the Black Lion Tamarin Population Management Program. <\/p>\n\n\n\n
During the workshop, specialists updated the 2021 population viability model, which guides the planning of management actions. Based on the new discussions, they assessed and identified populations and areas requiring management according to the modeled scenarios; carried out population viability analyses to identify populations eligible for management; and established a minimum number of individuals or groups to be managed within a certain timeframe in order to ensure population viability \u2013 all of these being actions under the PMP-MLP. <\/p>\n\n\n\n The Black Lion Tamarin Population Management Program includes professionals from the National Center for Research and Conservation of Brazilian Primates (CPB-ICMBio), the S\u00e3o Paulo State Forestry Foundation, managers of protected areas that shelter the species (ICMBio and FF\/SP), ex situ institutions (S\u00e3o Paulo Zoo, Guarulhos Municipal Zoo, and the Wildlife Research and Conservation Center \u2013 CECFau\/SEMIL-SP), university researchers (LaP\/UNESP and LabBMC\/UFSCar), and IP\u00ca \u2013 Institute for Ecological Research. <\/p>\n\n\n\n During the workshop, the group aligned on the fact that the black lion tamarin population of the Cap\u00e3o Bonito National Forest (Flona), in Alto Paranapanema, is also a priority. \u201cThis is the population with the greatest genetic diversity recorded for the species,\u201d highlights Gabriela. <\/p>\n\n\n\n The challenge lies in the ongoing concession process for the Cap\u00e3o Bonito National Forest for forest management, in which around 3,000 hectares out of a total of 4,200 will be cleared and, in the future, restored with native species. This is an area of planted forest, predominantly pine and eucalyptus, interspersed with native forest in riparian zones, in addition to araucaria plantations. The tamarins use both the native forest and the pine stands, as these are older areas with a well-developed understory. \u201cThe models showed us that removing some groups from the area to be cleared is an important alternative for safeguarding the genetic diversity of this population,\u201d explains Gabriela. <\/p>\n\n\n\n![\"\"](\"https:\/\/ipe.org.br\/images\/Evento_MLP_2026_foto2-1024x472.jpeg\")

Among the professionals present was F\u00e1bio Stucchi Vanucci, responsible for the models and scenarios of population viability analysis at the Conservation Planning Specialist Group of the IUCN Species Survival Commission (SSC-CPSG\/IUCN), which provided support in planning the workshop with an exclusive focus on population management.\u00a0<\/p>\n\n\n\nSafeguarding the Population with the Greatest Genetic Diversity of the Species<\/strong>\u00a0<\/h2>\n\n\n\n
