Cerrado Enclave and the Update of the Mapping of Landscape Units in the State of Rio Grande Do Norte

Abstract

The mapping of landscape units is a dynamic process in which constant modifications are needed. Based on this, this article sought to update the mapping of landscape units in the state of Rio Grande do Norte. This was possible due to the combination of field activities and new methodological procedures, with analyzes and refinements of previous mappings conducted by Silva (2018), Bernardino (2019), and Souza (2020). The main result is the update of a mapping that includes the (re-) delimitation and (re-) classification of Morphoclimatic Domains, Natural Regions, and Geocomplexes in the territory of this state. A new unit was identified and inserted: a cerrado enclave, which, until then, had not been described and analyzed as such in the established literature; consequently, one more natural region and two geocomplexes were mapped and delimited. New territorial occurrences of units already identified/classified in the original work were also mapped and, therefore, there was a resizing of landscapes of different taxa, which resulted from these modifications and of the refinement of their limits, due to the greater scalar detail, with the deepening of the research.
