The present study aims to assess, for the period between 2008 and 2019, the burning regime in the Chapada dos Veadeiros National Park (CVNP), Conservation Unit (CU) located in the state of Goiás that had its area expanded in this period. From images of Landsat and CBERS, fire scars were identified, vectorized, and analyzed for their location, size, and frequency. The current area of the CVNP burned about 542,113 hectares, i.e., more than 225% of the area of the CU. Approximately 76% of the scars were recorded in the expanded area of the Park, which had the highest participation of fires in 10 of the 11 years analyzed. It was possible to discriminate two burning regimes: one that covers the old limit of the Park, characterized by the low occurrence of fire, with the presence of features that resemble firebreaks and low frequency of fires; And another in the enlarged area, with a history of annual burning with values closer to the average, absence of linear scars and a maximum frequency of 10 occurrences. The unification of these panoramas in a single territory will require efforts to homogenize the regimes and may, associated with other actions, reduce the unpredictability of fires, and their impacts, legitimizing the role that CU have in the conservation and preservation of nature.
