Two other important developments during these years were the Migratory Bird and Mammal Treaty with Mexico in 1936 and the Lea Act of 1948. The latter legislation served to greatly increase the acquisition of waterfowl habitat in California. The Bankhead-Jones Farm Tenant Act, passed in 1937, was the authority used for establishing a number of wildlife refuges across the country. Under this Act, certain lands acquired by the Resettlement Administration were designated by Executive Order for management as refuges. Refuges acquired under this authority include Carolina Sandhills in South Carolina, Piedmont in Georgia, Noxubee in Mississippi, and Necedah in Wisconsin.
