When logging is carried out in a watershed, a likely effect on the local stream is

A. increased water temperature

B. increased oligotrophic conditions

C. decreased input of sediments decreased nutrient levels

D. mitigation on anoxia

correct option is A. increased water temperature

Explanation:

solution

As we know that logging is carried out anywhere in watershed that it will increased temperature as when watershed is partially clear cut or logging completely

then there will be decrease concentration of the dissolved oxygen and clear cut also reduced forest cover that also increase temperature

and generally by deposition of fine sediment in the gravel also carried out logging

so correct option is A. increased water temperature
