Among the categories of conservation units, the Natural Monument (MoNa) presents a high challenge because it is established areas. MoNa Morro de Santo Antônio is the only one in the state of Mato Grosso and degree of preservation is unknown. Thus, the objective of this work was to evaluate the use and occupation of the soil after the creation of MoNa Morro de Santo Antônio in the state of Mato Grosso and its influence on biophysical parameters from remote sensing techniques. For this, images of the surface reflectance obtained by Landsat 5 and 8 were used. The vegetation classification in the MoNa Morro de Santo Antônio was supervised. The estimated biophysical parameters were the Normalized Difference Vegetation Index (NDVI), Enhanced Vegetation Index (EVI) and the Normalized Difference Moisture Index (NDMI). The results presented in this work show that after the creation of MoNa Morro de Santo Antônio the native Cerrado class increased by 3.38%, the Undergrowth vegetation increased by 5.59% and the Forest dense class increased from 2.21% between 2006 and 2015. The Undergrowth vegetation class had a greater predominance. All indexes were lower in 2006 and higher in 2015. The results of this study are preliminary, but indicate that the creation of MoNa Morro de Santo Antônio in Mato Grosso influenced the preservation of its vegetation.
ecossistema em diversas escalas. Diante disso, o objetivo deste trabalho foi avaliar os efeitos sobre o uso e ocupação do solo, após a criação da unidade de conservação Monumento Natural Morro de Santo Antônio no Estado de Mato Grosso. O estudo foi realizado no Morro de Santo Antônio, distante 15 km da capital do Estado de Mato Grosso, localizado na divisa dos municípios de Cuiabá e Santo Antônio de Leverger no Cerrado Brasileiro. Foram adquiridas, junto ao USGS, imagens dos satélites Landsat 5 e 8, dos anos de 2005 a 2015, com resolução espacial de 30 m. Para o estudo da dinâmica da vegetação foram computados os índices de vegetação e de umidade da superfície NDMI. Os resultados apresentados neste trabalho demonstram que após a criação da MoNa, o índice foi menor no ano de 2006, enquanto que no ano de 2015 foi maior.Palavras-chave: Sensoriamento Remoto.

Therefore, the objective of this work was to evaluate the effects on the soil use and occupation after the creation of the conservation unit Morro de Santo Antônio Natural Monument in the state of Mato Grosso. The study was carried out in Morro de Santo Antônio, distant 15 km from the capital of the State of Mato Grosso, located at the border of the municipalities of Cuiabá and Santo Antônio de Leverger in Brazilian Cerrado. Images from the Landsat 5 and 8 satellites were acquired from the USGS from 2005 to 2015, with spatial resolution of 30 m. For the study of vegetation dynamics, vegetation and moisture indexes of the NDMI surface were computed. The results presented in this study demonstrate that after the MoNa creation, the index was lower in 2006, while in the year 2015, was higher.Keywords: Remote Sensing. Conservation Unit.
