Community participatory action to build a canopy bridge for wild black and gold howler monkeys (Alouatta caraya) in northern Argentina

The combination of urbanization and destruction of native forests commonly has forced wild animals to search for food and shelter in urban areas. Groups of black and gold howler monkeys (Alouatta caraya) are moving into urban areas in Northern Argentina as a consequence of rapid alteration and degradation of their habitats. In general, local people in the area are unaware of and disconnected from conservation actions, such as the protection of local biodiversity. We aimed to address this issue by organizing a group of high school students from both the city of Corrientes and outlying rural areas with the objective of transforming their perceptions on local non-human primates and to build the inaugural canopy bridge to instill biodiversity appreciation. With the students, we identified a location to install a bridge to facilitate the movement of Alouatta caraya across areas of discontinuous canopy. The students worked to build awareness within their community, obtained the necessary permission, and designed the bridge. From the beginning of the awareness campaign to the bridge installation, the process took four years. Afterwards, we installed two more bridges in the same region. From this single case study, we learned that participatory actions are a very important tool for residents of local communities to act collectively to promote biodiversity conservation.
