El Bosque Rayeros is a Natural Reserve in the Magdalena Valley, located in the center of Colombia. Historically this has been a cattle ranching farm for almost a century. In 2021 we started to change history. Tropical forests of the Magdalena in Colombia are megadiverse ecosystems that are home to an immense number of endemic and unique species in the world. These forests are at serious risk of extinction due to the effects of human activities that have fragmented and degraded them since several years.
