- Abstract
This study aimed to estimate the landscape structural changes of caatinga vegetation in the Sergipe semiarid region occurred between 1992 and 2013 by using remotely sensed data and landscape metrics. Landsat satellite images were used to classify forest (caatinga vegetation) and non-forest (other land uses) in the study area. The landscape metrics were estimated using the Fragstats® software. This study results estimated an increase of fragmentation (13.7%) of the caatinga vegetation during the time-period of 1992-2003. Additionally, we estimated a decrease of the central patch area of caatinga during the time-period of 2003-2013 (38.1%) and a decrease of 11.2 and 42.9% of the total area of forest class during the time-periods of 1992-2003 and 2003-2013, respectively. The remaining patches of caatinga vegetation must be appropriately considered as a high priority for conservation and it will require strong command and control policies and environmental law enforcement to avoid further deforestation and caatinga fragmentation in the study region.
