The Chacoan Peccary was thought extinct until it was rediscovered as a living species in the Chaco region of Paraguay in the 1970s. At present, the region is going through an unprecedented wave of deforestation, with over 1000 hectares of forest cleared daily. Wild populations of the endangered Chacoan peccary are currently facing the fastest and most extensive habitat loss ever recorded in recent history. To better understand the current conservation status we carried out surveys and interviews throughout the species former range in the Chaco region of Paraguay. From gathered location data, an ecological niche model was created using the Maxent program, to create an updated distribution map. The model showed that most of the species former range remains the same. However, the central southern portion of its range has suffered intense land transformation, which has negatively affected the presence of the species. On the other hand, the northern portion of its range, consisting of national parks and private lands that still mostly remain undeveloped, currently has the highest probabilities of occurrence of Chacoan peccaries. Our survey offers vital information, giving us the ability to create an updated species distribution map for Paraguay. Helping identify habitat limits, boundaries and possible barriers as well as, specific sites that need immediate attention. Similarly, our interviews have provided important information that needs consideration when implementing conservation policies, management plans, or community work to raise awareness regarding the importance of conserving the Chacoan peccary and the rich Gran Chaco biodiversity.
