Spectacled bears (SB) (Tremarctos ornatus) are the only bear species native to South America. This particular bear is the single species of its genus, and it is listed as vulnerable according to the IUCN red list. A critical SB conservation habitat is in the rural territories of the Peruvian Amazon, where anthropogenic land-use changes and landscape fragmentation threaten SB habitats. The following questions arise in this context: How much has land-use changed? How to design the establishment of ecological corridors (ECs) to support the conservation of SB?. We investigated the temporal land use and land cover changes for last 30 years (1990–2020) for a better projection of the ECs and to quantify the temporal landscape metrics. Furthermore, we integrated cloud computing, machine learning models with cost-effective techniques to delineate the ECs for SB within the rural territories. Ensemble Random Forest model associated with Google Earth Engine (GEE) was used to develop four land use and land cover (LULC) maps (for the years 1990, 2000, 2010 and 2020). The least cost path (LCP) model based on Dijkstra’s shortest path algorithm was assembled based on six variables (altitude; slope; distance to roads; distance to population centers; land use map; inventory map of SB). Then, we calculated the ECs based on the multidirectional origin-destination points, we found that forest patches increased by 57% between 1990 and 2020. Results showed statistically significant agreement (R2 = 0.47; p

Based on a review of literature related to the biological diversity of the inter-Andean Seasonally Dry Tropical Forest of the Marañón valley (ISDTFM), located in the regions of Cajamarca, Amazonas, Piura, La Libertad, Ancash and Huánuco (Perú), this study highlights the richness of endemic species of woody flora and tetrapod fauna, as well as addressing their threats and state of conservation. In fact, we report 143 woody flora endemics, most notably the species, Coursetia cajamarcana, Parkinsonia peruviana and Pradosia argentea, due to its Critically Endangered (CR) by the IUCN. Regarding tetrapod fauna endemic, there are four species of amphibians, 28 of reptiles, 22 of birds and six of mammals; outstanding among them Synallaxis maranonica due to its Critically Endangered (CR). A well-known problem with this forest is that it has been severely threatened by the expansion of the agricultural frontier and access routes, a situation that could become even more exacerbated if energy and extraction activities are developed. On the other hand, only 1.01% of all these forests, are protected under Protected Natural Areas (PNA). For this reason, it is essential to have this information in order to prioritise its conservation and protection.
