Golden-Headed Lion Tamarin: A Jewel of the Southern Bahian Cabruca

With predominantly black fur and a golden mane framing its face, the golden-headed lion tamarin, Leontopithecus chrysomelas (Kuhl, 1820), is a small callitrichid primate endemic to the Atlantic Forest, whose distribution has been reduced to southern Bahia, Brazil (TEIXEIRA et al., 2023). These social animals live in family groups that practice cooperative infant care, in which all group members participate in raising the offspring (ELSACKER et al., 1992). Omnivorous by nature, they feed on fruits, flowers, nectar, and small animals (RABOY; DIETZ, 2024). While foraging, they act as important seed dispersers and pollinators, actively contributing to forest dynamics and regeneration (RYLANDS et al., 2008).

The species’ primary threat is habitat loss and fragmentation, as the Atlantic Forest in the region has been reduced to isolated forest fragments surrounded by open and human-modified landscapes (PIOVESAN; KIERULFF, 2015). Furthermore, disease outbreaks such as yellow fever represent an increasingly severe threat to already vulnerable populations (DIETZ et al., 2019). Within this scenario of intense anthropogenic pressure, and with the species already classified by the IUCN as endangered, cabruca agroforestry systems play a crucial role in the conservation of these callitrichids (CASSANO et al., 2014).

Cabrucas are agroforestry systems in which cacao trees are cultivated beneath the shade of native trees, creating an environment characterized by a continuous forest canopy, abundant lianas, and large trees rich in bromeliads and natural cavities used for shelter and feeding (PINTO; TAVARES, 2007). These structural features provide important ecological elements capable of sustaining populations of lion tamarins with performance levels comparable to those found in native forest fragments, thereby functioning as primary habitats rather than merely ecological corridors (LLEWELLYN, 2011; FLESHER, 2015).

However, the cacao economic crisis that began in the 1990s due to the witches’ broom fungus (Moniliophthora perniciosa) indirectly threatens the species by encouraging the replacement of cabruca systems with pasturelands or full-sun monocultures, consequently intensifying deforestation (ALMEIDA; LIMA, 2018).

The conservation of the golden-headed lion tamarin requires a transdisciplinary and integrated approach, including educational efforts aimed at promoting agricultural practices compatible with biodiversity conservation, as well as the integration of both in situ and ex situ conservation strategies. Currently, initiatives such as Projeto BioBrasil and the Almada Mata Atlântica Project (AMAP) are dedicated to this cause and may be supported through their social media platforms. Additionally, the Geographical Indication Cooperative “Cacau Sul da Bahia” allocates three percent of its profits to conservation initiatives focused on the golden-headed lion tamarin.

There are also biological reserves of extreme importance for the maintenance of the species, such as the Una Biological Reserve, monitored and managed by the Chico Mendes Institute for Biodiversity Conservation (ICMBio). Together, all these efforts provide a measure of hope regarding the conservation of these remarkable small primates.
