Análisis multitemporal del Bosque Montano Alto en la parroquia Baquerizo Moreno cantón Pillaro provincia de Tungurahua en los periodos 2015-2020.

Abstract

This research aimed to know the changes in forest cover using satellite images for 2015-2020. Descriptive methods and non-experimental descriptive analysis were applied, which allowed the use of GIS tools for the process and analysis. This determined the information on the loss of the High Montane Forest of the Baquerizo Moreno town due to deforestation and agricultural intervention by using satellite images on the following dates: November 2, 2015, November 20, 2016, December 13, 2017, October 24, 2018, October 22, 2019, August 11, 2020. This allowed the classification of the coverage and the analysis of fragmentation and qualified to evaluate the variation and rate of changes of the range from the satellite images. Three areas with gains and losses were obtained as a result during the study period that is detailed below: there is a loss of 98.07 ha, which represents -1.11% in the high montane evergreen forest zone, in the moorland grassland zone, indicates a gain of 39.33 h a, which means 2.22 % and in the agricultural intervention zone suggests an increase of 58.74 ha, which represents 0.10%. In the fragmentation analysis, it was known that there is fragility and insularization in the study coverage. The changes obtained are produced due to human intervention, generating losses in range. Then, the alternative hypothesis is accepted, which states that significant changes in forest cover occur through multitemporal analysis in the Baquerizo Moreno parish in the periods 2015-2020. It was recommended to work using LandSat8 or Sentinel-2 as a reference to obtain better results and exact data to know the forest cover changes.
