“…Although in the PRZ-CRV there are processes of changes in the natural cover, forests of the region conserve a structure and floristic composition typical for tropical humid forests (Ortiz-Lozada, 2020). This is also supported by some recent studies that report the presence of bioindicator species of high-quality habitats in relict forests in southern Bolivar (Arbeláez-Cortés et al, 2021). Therefore, the higher forest coverage in the PRZ-CRV, the greater species diversity, and the peasant commitment to the conservation of their natural resources make this area a potential ally for the biodiversity conservation of the region.…”

Tropical forests of Colombia have one of the highest deforestation rates in the world. The humid forest of the Magdalena valley region is one of the ecosystems with the highest risk of landscape transformation, despite being home to many endemic and threatened species. The aim of this study was to evaluate the role of a Peasant Reserve Zone in the conservation of tropical humid forests and endangered species in the Magdalena valley region. To reach this aim, we performed a multi-temporal analysis of the forest dynamics in the Peasant Reserve Zone-Cimitarra River Valley (PRZ-CRV) and assessed the extinction risk of eight species endemic to Colombia. Our outcomes indicated that the most extended land cover in the PRZ-CRV is the forest (56.30%), followed by open areas (38.75%). The forest dynamics analysis indicated that the forest cover has decreased by 3.82% between 2017 and 2019, being the area with redoubts from the Serranía de San Lucas Forest the most conserved. Finally, our results indicated that less than 50% of the climatically suitable areas for each species are covered by forests and that less than 10% of those areas are covered by Protected Areas, while for such species as Agalychnis terranova and Ateles hybridus the PRZ-CRV covered a higher percentage of their distribution than all Protected Areas together in this ecosystem. In conclusion, our results have indicated that the PRZ-CRV could be an important area for the maintenance and conservation of humid forests and their associated fauna, playing an important role as an ally to the Protected Area system in the Magdalena valley region.

“…The case study unfolded within the ZRC-VRC, a region distinguished by its abundant biodiversity, water resources, and natural forests [29][30][31][32]. Simultaneously, the area is characterized by the presence of numerous gold deposits in the subsoil and widespread poverty among the local population, where the local community is exposed to a higher rate of inequality and poverty.…”

“…These organizational processes have demonstrated the sustainable use of their territories for decades [30][31][32]; territories that have become a refuge for many species, some of them at high or critical risk of extinction, as well as strategic biological corridors for "umbrella species" such as the jaguar, the tapir, or the spectacled bear. From the results found in the biological characterizations carried out in the forest areas of community conservation agreements, particularly in the CoS, the following data stand out, certifying the high biodiversity present in the territories subdivided into species and most outstanding subgroups: Butterflies: 240 species; Small mammals: 28 species; Herptiles: 59 species collected; Primates: 5 species; Plants: 130 species; Aquatic Macroinvertebrates: 12 to 15 families identified; Birds: 250 species identified; Coprophagous beetles: 16 species; Medium and large mammals: 12 species identified (tapirs, jaguar, American cougar, ocelot, and jaguarundi, as well as the spectacled bear) [29,32].…”

Artisanal small-scale gold mining (ASGM) using mercury affects community agreements for the conservation of forests (CoS) and lakes (CoH), which have a high level of biodiversity in the Peasant Reserve Zone of the Cimitarra River Valley (ZRC-VRC) in Colombia. In this research, a multi-criteria approach (MCA) was applied to analyze the impact of ASGM. This analysis is based on the community environmental agreements to preserve CoS and CoH areas, the ecological importance of these areas, as well as the results of mercury dispersion in the Cimitarra river basin, with concentrations found 40 km downstream of the mining area of 0.09 µgTHg L−1 in the Cimitarra river, 0.07 µgTHg L−1 in the CoH, and 0.01 mgTHg kg−1 in the tissues of macrophytes, as well as the increase in deforestation since 2020 in the CoS, due to a 1.8% (990 ha) loss of forest cover, with 693 ha of the forest cover loss coinciding with areas related to the opening of new mines. The MCA showed that the main impact is found within the criterion Social and armed conflict, followed by Deforestation. This research offers recommendations to reduce impact scores, such as the implementation of a sustainable development plan (PDS) of the ZRC-VRC, and it highlights the urgent need to safeguard the community conservation areas.
