The Brazilian Pantanal is an area with specific biogeographic dynamics and its study becomes important in order to understand the landscape. The Pantanal plain has as its main economic activity cattle raising, highlighting the importance of the “cordilheira”, landscape unit that is considered vulnerable for sheltering fauna during periods of floods. The objective of this work is to promote the understanding of biogeographic dynamics in "cordilheiras" in the Pantanal do Abobral, one of the sub-regions of the Pantanal. To meet the proposed objective, at first, the selection of the sample targets was carried out, with two points of analysis - a mountain range located in a preserved area inside conservation unit (buffer area of the Pantanal do Rio Negro Nature Reserve), and located outside a protected area. Then, it was made an analysis of vegetation, pedomorphological, topographic dynamics and microclimate variations between the "cordilheiras". The results obtained make it evident that the mountain range located in a protected area has aspects considered preserved in comparison to the mountain range of the unprotected area. It is noted, in a general, that the livestock is influential in the process of modification of the Pantanal landscape and planning to reduce losses is necessary.
