Table 1. Landscape parameters in the sub-basins Beni, Guaporé, Madre de Dios, Mamoré, and Madeira, the latter including the upper, middle and lower sections of the Madeira River and excluding the areas of influence of the Jirau and Santo Antônio reservoirs, which are presented separately.
River Basin | Buffer | Perennial | Flooded | Forest 2013 | Forest Loss |
---|---|---|---|---|---|
Beni | 11675.05 | 231.87 (2.0%) | 728.20 (6.2%) | 9486.53 (81.3%) | 156.76 (1.7%) |

Madre de Dios | 7696.41 | 319.85 (4.2%) | 218.69 (2.8%) | 6741.39 (87.6%) | 50.00 (0.7%) |
Mamoré | 9910.02 | 585.62 (5.9%) | 1130.68 (11.4%) | 6055.59 (61.1%) | 87.00 (1.4%) |

Area (km2) occupied by different features within 6-km-wide buffers established on each bank along river channels (Buffer); permanent surface water area without seasonal variation (Perennial) from long-term global surface water mapping data; visible flooded area estimated to 2014 extreme flooding (Flooded); total area of forest cover in 2013 before flooding (Forest 2013); summed forest loss in 2014 and 2015 (Forest Loss). Calculation of forest loss in the reservoirs of Jirau and Santo Antônio excluded areas submerged by the filling of reservoirs. Therefore, only areas beyond the hydroelectric reservoirs were considered as forest loss. Percentage values in parentheses show the fraction of each metric (Perennial, Flooded, Forest 2013) in relation to the total area of the respective buffer and the percentage of Forest Loss is relative to the total area of forest cover in 2013 before flooding.
