This species is listed as Near Threatened in light of a projected future decline of around 25% over the course of three generations (18 years) due to anticipated high rates of deforestation. The forests where S. tripartitus occurs along the Rio Yasuni in Ecuador are remote and have, to date, suffered little impact from human activities, other than small localized encampments for petroleum prospecting. However, the occurrence of petroleum in the region, resulting in the current construction of the Pompeya-Iro highway, is reason for some concern for the future of these forests and their wildlife.[1]
