Abstract
El presente estudio describe y desarrolla un análisis comparativo de las metodologías aplicadas en la caracterización de la flora terrestre entre Estudios de Impacto Ambiental (EIA) aprobados del sector minero e investigaciones científicas publicadas. Esto se ha realizado seleccionando cuatro EIA y cuatro investigaciones científicas, y realizando la revisión de estas; se han descrito las metodologías para la evaluación de flora empleadas en cada uno de ellos, así como los parámetros utilizados para la caracterización de esta. Además, se presentaron las curvas de acumulación de especies asociadas a cada estudio y se describió el porcentaje registrado de especies esperadas en cada uno. Entre los estudios revisados se ha identificado que mayormente los EIA evaluados presentan un registro de especies esperadas menor al 80% y las investigaciones científicas evaluadas presentan un registro de especies esperadas mayor al 80%. Por otro lado, la cantidad de especies esperadas registradas en cada evaluación, tanto EIAs como investigaciones científicas, se puede ver influenciada por la metodología aplicada y los esfuerzos de muestreo empleados. Los parámetros para la caracterización de la flora utilizados en común en los EIA e investigaciones científicas orientadas a la caracterización y/o composición de la vegetación son: Riqueza (S), Índices de diversidad (Índice de Shannon Wiener), Especies endémicas y Hábitos de crecimiento.
This study describes and develops a comparative analysis of the methodologies applied in the characterization of terrestrial flora between Environmental Impact Studies (EIA) approved in the mining sector and published scientific research. This has been done by selecting four EIAs and four scientific investigations, and reviewing these; the methodologies for the evaluation of flora used in each of them have been described, as well as the parameters used for its characterization. In addition, the accumulation curves of species associated with each study were presented and the percentage of species expected in each one was described. Among the studies reviewed, it has been identified that most of the evaluated EIAs present a record of expected species of less than 80% and the scientific investigations evaluated present a record of expected species greater than 80%. On the other hand, the number of expected species recorded in each evaluation, both EIAs and scientific research, can be influenced by the methodology applied and the sampling efforts used. The parameters for the characterization of the flora used in common in EIAs and scientific research aimed at the characterization and/or composition of vegetation are: Richness (S), Diversity Indices (Shannon Wiener Index), Endemic Species and Growth Habits.
