| The Pantanal is about 140,000xe2x80x93160,000xc2xa0km2 (54,000xe2x80x9362,000xc2xa0sqxc2xa0mi),[8][9] gently-sloped basin that receives runoff from the upland areas (the Planalto highlands) and slowly releases the water through the Paraguay River and tributaries. | WIKI |
| [3] They shift between phases of standing water and phases of dry soil, when the water table can be well below the root region. | WIKI |
| [9] In the Paraguay River portion of the Pantanal, water levels rise between two meters to five meters seasonally; water fluctuations in other parts of the Pantanal are less than this. | WIKI |
| When rising river waters first contact previously dry soil, the waters become oxygen-depleted, rendering the water environs anoxic. | WIKI |
| [3] Many natural fish kills can occur if there are no oxygenated water refuges available. | WIKI |
| The reason for this remains speculative: it may be due to the growth of toxin-producing bacteria in the deoxygenated water rather than as a direct result of lack of oxygen. | WIKI |
| During this process, decomposing microbes deplete the shallow water of all oxygen, suffocating larger decomposers. | WIKI |
| To get oxygen, they extend a long snorkel to the water surface, pumping air into their lungs. | WIKI |
| [18] Pollution from gold mining operations and agro-industry [21] The Pantanal is a natural water treatment system as it removes chemicals, including pollutants, from water. | WIKI |
| However, water quality in the Pantanal was not significantly degraded as of 2002. | WIKI |
| For example, it is remarkable to see a group of giant water lilies, impressive aquatic plants, growing near to immense cactus from semi-arid regions. | UNESCO |
| These water courses also play a central role in diversing nutrients to the entire basin. | UNESCO |
| The level of fragility of the Pantanal is high and the effects of human practices (dredging, excessive fishing, deforestation, acute erosion, waste waters, waste materials, dams generating hydrodynamic changes, canalling of water courses) represent serious threats to the whole region. | UNESCO |
| The plans for the construction of navigable water courses in the region or other similar projects represent a real threat to the entire Pantanal. | UNESCO |
| This type of large-scale project would change the natural dynamics and structure of the water flow in the basin, and moreover the massive absorption capacity of flood waters in the Pantanal followed by its slow descent. | UNESCO |
