ESTUDIO DELEFECTO CAUSADO POR EL NIVEL DE INTERVENCIÓN HUMNA EN BOSQUE PROTECTOR CERROBLANCO SOBRE LOS PATRONES ECOLÓGICOS DE AVES ANDÉMICAS ENTRE EL AÑO 2020 Y 2021

Abstract

There are many animal species that are in danger of extinction, or others that have had to modify their behavior and habitat due to threats such as: habitat loss and transformation, direct overexploitation of species and natural resources, introduction of invasive or exotic species, environmental pollution and climate change. The main cause for the described scenario is human intervention, since it is considered a variable that conditions the ecological patterns of species. Given the above, the objective of this research is to analyze the effect of human intervention on the ecological patterns of endemic birds between 2020 and 2021 in the Cerro Blanco Protected Forest. The methodology is composed by an experimental design, where the data collection used counting points separated at least 150 meters. The counts were carried out at 11 points during 5 minutes, between 6:30 am and 11:00 am. A 50 m radius and binoculars were used for these sightings; a field investigation was also carried out to determine the number of visitors. The results determined that 45 endemic birds were sighted in 2020 and 50 in 2021; while the number of visitors increased from one year to another, so it is concluded that human intervention does not influence the ecological patterns of endemic birds. In addition, the statistical association analysis corroborates the above, since the Spearman correlation coefficient determined an index between the number of visitors and the presence of birds of 0.153, which expresses that there is no relationship.
