Endemism of woody flora and tetrapod fauna, and conservation status of the inter-Andean Seasonally Dry Tropical Forest of the Maran∼′on valley

Based on a review of literature related to the biological diversity of the inter-Andean Seasonally Dry Tropical Forest of the Maran similar to ' on valley (ISDTFM), located in the regions of Cajamarca, Amazonas, Piura, La Libertad, Ancash and Hu ' anuco (Peru), 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.

Automated summary

This study highlights the rich endemic species of woody flora and tetrapod fauna in the inter-Andean Seasonally Dry Tropical Forest of Maran similar to ' on valley (ISDTFM) in Peru, while emphasizing the threats they face and the limited conservation efforts. This information is crucial for prioritizing conservation and protection measures in the face of increasing threats from agriculture, development, and extraction activities.
