Our mission

The MNP project is fundamental at three levels:

1/ scientific research to increase knowledge about the macaques and their environment,

2/ education to empower local scientists and citizens to manage their own environmental and science programmes, and

3/ conservation to empower local populations and help them protect their environment while providing sustainable livelihood through eco-tourism, expert fauna-flora guiding, nature ranger activities and sustainable economic activities.

The crested macaques

Crested macaques are close to extinction as their population has decreased by more than 75% in the last 30 years. They are now one of the 25 world’s most endangered primates and will go extinct by 2050 if no change is made. Wild crested macaques suffer from habitat destruction and poaching for meat due to lack of public awareness and law enforcement.

Since 2006, the Macaca Nigra Project studies the biology and habitat of these enigmatic animals, who belong to the most tolerant primates described so far. At the same time, we protect animals in the wild, promote their conservation through collaboration with local authorities, awareness campaigns, education programmes and authority consultancy. 

trinity conservation


We collaborate with the local authorities and consult them on important conservation management decisions. Our long-term data base is of utmost importance here. We also regularly patrol the forest, destroy traps and release macaques from them. Any illegal activity is documented and immediately reported to rangers. In this way, we have already saved the lives of many animals, not only macaques.

Learning about macaques through games and role play

Environmental education is the key to sustainable conservation. We therefore inform and educate local pupils and adults of all ages using the crested macaque as an icon animal. Most importantly, we collaborate with local authorities to get our lessons implemented into school curriculars.
