At the end of June, we finished one year of studying the behaviour and ecology of the Critically Endangered San Martin titi monkey (Plecturocebus oenanthe) at Yantalo in San Martin, Peru. Data from this study will allow us and others to better understand the species’ conservation requirements for its survival. The site continues to be available to other researchers who wish to study the species, which will also help provide employment to local community members.
We have also begun new surveys of Critically Endangered yellow tailed woolly monkeys (Lagothrix flavicauda) at our original field site at La Esperanza, in Amazonas, Peru. To begin with, we are repeating population density surveys that we carried out in 2008/09 and 2012/13. In the previous studies we found that the species’ population at the site had grown and that deforestation rates had dropped. We are hopeful that the population has continued to grow, or reached its maximum size, since the last survey. We’ll keep you updated as results become available.
