Table 3 A summary of the effects of the conversion of primary forest to pastures and ranches on the downstream riverine and estuarine water properties. The arrows before the water properties indicate that the subsequent water properties increased (↑), decreased (↓), or did not change (→). See the list of abbreviations for the water properties
