Northern Prairie Wildlife Research Center
A 2-year study was made of breeding bird populations of three gravel pits. Fishing during the close season is an important factor in determining the composition of bird communities and actual numbers of nesting pairs. Deleterious effects of close season fishing appear to be largely indirect--general disturbance and denudation of the bank vegetation. It is recommended that close fishing season be prohibited wherever possible and carefully controlled where complete prohibition is not practicable, chiefly for the sake of the birds.
