How did our International GLT Day start?


Golden Lion Tamarin Day – August 2, 2016 - download the video!

One of AMLD’s strategies to engage the local community in GLT conservation is to increase pride in the local forest and recognition that GLTs exist nowhere else in the world.  On August 2, 2016, Andreia Martins, coordinator of the field team who monitors GLTs, carried the Olympic Flame through the region on its way to the Rio Olympic Games. 

With local schools and businesses, AMLD organized a celebration in Silva Jardim, Andreia’s home town, recognizing Andreia and her field team as local heroes. Silva Jardim, is also where the largest population of wild GLTs live, in the federally protected Poço das Antas Biological Reserve and in the forest on private land. The Silva Jardim Municipal Council officially recognized August 2, 2016 as “Dia do Mico-Leão-Dourado” (Golden Lion Tamarin Day). AMLD and SGLT started celebrating International GLT Day the following year on August 2nd, 2017, and have supported GLT fans around the world in celebrating this day ever since. 

In 2018, the Brazilian government officially declared August 2 as National Golden Lion Tamarin Day.
