The Southern Muriqui (Brachyteles arachnoides) restricted to the Serra do Mar mountains of South East Brazil and classified as “endangered” on the IUCN red data list, used to have a much larger home range.
Sadly forest loss, fragmentation, timber extraction and urban expansion reduced its home range area and today the sighting of this magnificent species is really rare. Some retired hunters have never seen them!
Rildo da Rosa Oliveira is one of REGUA’s team of rangers. Rildo, who is funded by the World Land Trust “Keepers of the Wild” programme, caught these amazing photographs of the species with young of various ages indicating the population is stable and healthy.
Rildo (himself an ex-hunter) is engaged in helping University researchers in their studies. REGUA likes to promote research in the Reserve as a means to maintain a positive presence in the forests which are home to peccaries and pumas, the Solitary Tinamou and the Variegated Antpitta as well as important tree species. Maintaining a low impact and constant presence dispels the hunters and charismatic important species such as the Southern Muriqui become less flighty over time.
These animals are now being more regularly sighted and specialist André Lanna suggests REGUA might be home to the largest population of the Muriqui in South East Brazil, or the world for the matter, as the species is endemic to this region.
REGUA wishes to thank the World Land Trust for their support that permits ranger Rildo to keep a whopping 2500 hectares free for the species and the forests of hunters.
