Impending extinction of the world’s primates due to human activities; immediate global attention is needed to reverse the trend.

Peruvian yellow-tailed woolly monkeys (Oreonax flavicauda) are considered Critically Endangered (IUCN Categories A4c). The International Primatological Society also considers them one of the world's 25 most endangered primate species and therefore a conservation priority. However, there is little concerted conservation action, and the existing protected area network may be inadequate to protect this species from extinction. Until recently this species has been the focus of few studies and its distributional limits remain unknown. I present results of a range-wide survey of Oreonax flavicauda in northeastern Peru. I conducted 53 presence/absence field surveys at 43 sites between March 2007 and March 2010, with data collected for an additional 7 sites from other researchers. I chose sites where the species was previously reported or following suggestions from predictive GIS modeling. Oreonax flavicauda was present at 35 sites, all presence records were in Ficus spp.-dominated cloud forests between 1500 and 2650 m above sea level. I give the geographical limits of this species distribution throughout the north, east, and west of its range; the exact extent of its range to the south requires further investigation. Oreonax flavicauda continues to be threatened throughout its range. The major threats I identified at the survey locations were the continued conversion of forests to cattle pasture, opening of new access routes into virgin areas, and both commercial and subsistence hunting. My results suggest that existing conservation measures may be inadequate at protecting this species but that substantial opportunities do exist. Further surveys need to be made in the southern distribution of this species to determine more accurately extant habitat.

Peru has one of the richest primate faunas of any country. The illegal trade in wild primates is one of the largest threats to this fauna in Peru. We characterize the illegal trade in primates through empirical and ethnographic data. We collected data from traffic routes and centers throughout Peru and evaluate current efforts to combat this traffic. Based on our findings from 2,070 instances of wildlife crime involving 6,872 primates, we estimate the domestic trade in primates for pets and bushmeat in Peru in the hundreds of thousands per year, with the larger bodied Atelidae facing the highest direct consequences. We found that government authorities lack sufficient staff, capacity, resources, infrastructure, and protocols to efficiently combat illegal trade in primates. Also, the complicated legal framework and lack of cooperation and antagonism with the public further limit these efforts. Wildlife authorities in Peru are able to confiscate only a fraction of primates traded and mostly intervene in cases of private pet owners rather than traffickers. We estimate that the current rate of illegal trade in primates is comparable to levels of trade prior to the 1973 ban on primates' exportation. The combination of direct observations on primate trade and ethnographic data allows a comprehensive look at primate trade in Peru. We call upon decision makers and international funders to channel their efforts toward "on the ground" actions such as increasing the ability of the authorities to act, giving them "in action" training in law enforcement and establishing strict control measures against corruption.

Primates, represented by 521 species, are distributed across 91 countries primarily in the Neotropic, Afrotropic, and Indo-Malayan realms. Primates inhabit a wide range of habitats and play critical roles in sustaining healthy ecosystems that benefit human and nonhuman communities. Approximately 68% of primate species are threatened with extinction because of global pressures to convert their habitats for agricultural production and the extraction of natural resources. Here, we review the scientific literature and conduct a spatial analysis to assess the significance of Indigenous Peoples’ lands in safeguarding primate biodiversity. We found that Indigenous Peoples’ lands account for 30% of the primate range, and 71% of primate species inhabit these lands. As their range on these lands increases, primate species are less likely to be classified as threatened or have declining populations. Safeguarding Indigenous Peoples’ lands, languages, and cultures represents our greatest chance to prevent the extinction of the world’s primates.

Amazonas and San Martin are two of the most densely populated regions in rural Peru and have some of the highest deforestation rates in the country. They are also home to many threatened and endemic species and are considered a high priority for conservation. Under Peruvian law individuals and community groups can create private conservation areas and conservation concessions, and we evaluated the successes and challenges experienced in the creation and management of such areas, using direct observation, questionnaires and key-informant interviews. Our results show that far from being a problem for conservation many rural communities are actively promoting or participating in conservation initiatives on a local scale with landscape-level impacts. These initiatives include land protection, hunting control and reduced deforestation, thus providing effective solutions to threats. The main obstacles we identified in relation to such campesino (peasant farmer) conservation initiatives were the lack of access to support from governmental and nongovernmental institutions and to economic resources to fund the extensive bureaucratic processes of registering protected areas. Many campesino communities bypass these restrictions through informal conservation initiatives.
