Natural flooding is the primary form of disturbance in this ecoregion.
Flood protection has reduced natural flooding by an estimated 50-90% degrading habitat for migratory birds.

From the 1940s to the 1970s large parts of the forest were converted to agriculture, primarily for soybean production.
Roughly 25% of the historically forested area remains.
Calculations made in 2002 estimate that the region consists of 86,938 forest patches with an average size of 42 hectares.
Fewer than 100 of these patches are thought to be large enough to support a self-sustaining population of forest breeding birds.
