abstract = "Despite a 79% reduction in deforestation rates since 2004 in the
Brazilian Amazon, the current gross forest loss of 6207 km2 year-1
remains significant, promoting continuous habitat fragmentation.
This study assessed the status of forest fragmentation in 2014
across the Brazilian Amazon applying a Morphological Spatial
Pattern Analysis (MSPA). Our analysis provides the first
60-m-resolution fragmentation map for the entire Brazilian Amazon,
including not only the commonly evaluated fragmentation classes
such as core, edge and islet, but also four specific metrics
measuring the effects of fragmentation on forest patterns
(perforation, bridge, loop and forest branches). Areas of intense
forest fragmentation were detected not only along the arc of
deforestation of the eastern and southern Brazilian Amazon but in
other regions as well. Considering a 1020-m edge width, we found
that 28% (*891,000 km2 ) of the remnant forest was in noncore
classes. Among these classes, bridge (i.e., forest corridors too
narrow to contain core area) was the most representative (10.8%).
The proportion of core area varied greatly among states, from
82.8% of the remaining forest in Amazonas to 26.1 and 13.5% in
Maranhao and Tocantins, respectively. The detailed diagnosis of
tropical forest fragmentation is a critical step for proposing
solutions to maintain the stability of tropical forest services,
including carbon storage, water and nutrient cycling, and
biodiversity.",
