This is the official national dataset of BLM's Taylor Grazing Act (TGA) grazing district boundaries which portrays the grazing districts established or subsequently modified under the Taylor Grazing Act. BLM TGA grazing district boundaries are separate and distinct from BLM administrative districts, which were not established until BLM was formed (under Reorganization plan #3 of 1946) by combining the General Land Office and the Grazing Service.

The Taylor Grazing Act of 1934 authorized the Secretary of the Interior to provide for the orderly use of livestock grazing on the public domain lands that “in his opinion are chiefly valuable for grazing and raising forage crops”.

Under Section 3 of the Act, grazing permits are issued on public lands within the grazing districts established under the Act. Under Section 15 of the Act, grazing leases are issued on public lands outside the original Grazing District boundaries. Receipts from grazing on Section 3 lands are distributed differently than receipts from grazing on Section 15 lands:

TGA Section 3:

- 50.0% Range Betterment Projects

- 12.5% Returned to the State

- 37.5% U.S. Treasury

TGA Section 15:

- 50% Range Betterment Projects

- 50% Returned to the State
