mountain marmosets conservation program


The Mountain Marmoset Conservation Program is focused on the conservation of two endangered marmosets found in the mountainous regions of the South-eastern Atlantic Rainforest, Brazil.  


In the wild the Buffy headed marmoset (Callithrix flaviceps) and the Buffy tufted-ear marmoset (Callithrix aurita) both face high levels of habitat fragmentation, population isolation and an increasingly acute threat from invasive marmoset species causing hybridization. Although more than 30 years ago there were concerns highlighted about the species conservation status, it was only more recently that these two species have become the focus of a conservation program! 


We hope that you will join the program, get involved and help us to resolve the problems that are currently threatening both species survival in their natural habitat.


To restore the biodiversity of the Atlantic Rainforest

by conserving endemic primate species



To conserve viable populations of Callithrix aurita and Callithrix flaviceps in their naturally occurring area, for the prosperity of the environment and

present and future generations

Importance of surveys

Surveys are fundamental to data collection. In addition to identifying habitats and the distribution of populations in the forest fragments, surveys sometimes lead researchers to connect with rural communities and the outer reaches of highly urbanized areas.

Community engagement is a high priority for researchers. Take a look at our short pictorial video to gain an insight into one example of an unremarkable forest fragment that reveals a very remarkable story!
