Charles H. Lawrence, 67, retired head of the enforcement division of the U.S. Fish and Wildlife Service, died of Cancer Thursday at his home in Arlington.

He retired in 1972 after 26 years with the agency, where he was considered a pioneer in wildlife management. Mr. Lawrence had joined the Fish and Wildlife Service in Illinois in 1946. He came to Washington a year later. He became chief of enforcement in 1967.

During his tenure, he had organized a force of undercover agents who arrested waterfowl poachers in a number of states. He also directed a group of agents who infiltrated the ranks of commercial hunters of endangered big game animals protected by federal law.

Mr. Lawrence directed an investigation that led to indictments in the poisoning and shooting of more than 500 bald and golden eagles in the West. He received the Interior Department's Meritorious Service Award.

Born in Spokane, Wash., the son of a lumberman, Mr. Lawrence grew up in Wisconsin. He attended the University of Wisconsin and worked as a game warden before World War II.

During thewar, he was an artillery commander in Europe and participated in the Normandy invasion. He also served with the military government in Germany. He left the Army in 1946 with the rank of major.

He is survived by his wife, Dorothy, of the home and a daughter, Judith, of Fairfax County.

The family suggests that expressions of sympathy may be in the form of contributions to Children's Hospital.
