description Marajó várzea Overview
Marajó várzea is an ecoregion on Marajó Island at the mouth of the Amazon River in northern Brazil. It consists of seasonally flooded grasslands, savannas, and forested areas shaped by the annual rise and fall of river and rainwater. The flood cycle supports aquatic and wetland wildlife, including numerous birds, and has also made the region suitable for extensive water-buffalo ranching. Its ecology differs from the permanently forested parts of the wider Amazon basin.
