5.3 BritishColumbia
In British Columbia, Bald Eagles are pro- tected by the Wildlife Act, under which it is il- legal to harm or molest Bald Eagles, their nests and eggs. Recent amendments now pro- tect the nests, whether or not they are occu- pied. Other Acts, both Provincial and Federal, indirectly offer some protection to Bald Eagle habitat; including the provincial Pesticides Control Act, which controls the use of pesticides; the Waste Management Act, which regulates water quality and discharge of pollutants; and the Park Act and Ecologi- cal Reserves Act, which protect some nesting habitat.
