Jaú National Park

　　    Jaú National Park (JNP) is situated about 200 kilometers northwest of Manaus. It originally formed at the confluence of the Jaú River and the blackwater rivers, and later expanded along the right bank of the Jaú River all the way to the mouth of the Carabinani River. The park then continued to extend further up the right bank of the Carabinani River before eventually meeting the Rio Negro once again. The elevation within the park ranges from 0 to 200 meters. The forests in the park are connected to the continuous forests spread across the vast central plains of the Amazon, surrounded by the low-lying Rio Negro, creating a unique landscape in the region.

　　    Representative vegetation includes: tropical rainforest primarily found in terrestrial environments, lush and generally spared from flooding during the wet season. This type of forest is usually stratified, with approximately 180 plant species per hectare; open tropical rainforest, which, clearly, is ecologically and visually related to tropical rainforests. Its main characteristics include shorter trees, slender trunks, a tree canopy layer, and frequent presence of epiphytes from the same family.

　　    In addition, due to growth in sandy soils with relatively poor nutrient supply, there are on average 108 plant species per hectare, among which light-colored dryland deciduous shrubland makes up the largest proportion. Here, taller dominant trees as well as epiphytes and lianas are relatively scarce and rarely seen.
