Estudio multitemporal de cambio de uso del suelo, patrones de distribución de plantas y estatus de conservación en la provincia de los ríos

The province of Los Ríos has undergone significant changes in the last 30 years due to increased agricultural activities and forest loss, which poses the threat of accelerated biodiversity loss and degradation. In this context, this research focused on analyzing land use change, plant distribution patterns and their conservation status in the province. To achieve these objectives, a multitemporal analysis of land use was initially carried out taking into account the 1990 and 2022 vector files of MAATE. On the other hand, with respect to the second objective, data were obtained from open access biodiversity databases (GBIF, SISBIO). Finally, regarding the UICN categories, this process was carried out using the taxize package developed for the R programming language. Among the main findings, it was reported that there was a 4,36% loss of vegetation cover and a 19,84% increase in agricultural and livestock activities. In addition, it was identified that the province has 2798 plant records reported and 1564 species identified. Of this total, only 15% of the species analysed are found in protected areas. In terms of UICN conservation categories, 1,5% of the species studied were classified as Vulnerable (VU), while 25,8% were considered Vulnerable (VU), while 25,8% were considered Vulnerable (VU).
