Sorry, blanket statements like that are not the case. In the case of the Desert Tortoise, the BLM is beholden to the listing by the US Fish & Wildlife services and management according to the Congress act. While they obviously have much latitude in how they execute those laws (and Act of Congress is a law) and thus making their own internal regulations, they are beholden to the Act. Spend some time reading
FLPMA, it ties many hands including the motorized community. The laws of the 70's including the repeal of RS2477 (part of FLPMA) were not kind to the motorized community and public land users we are associated with. Want to fix that? Get FLPMA repealed or amended to protect public land users. Until then, WAG's and anti-motorized/industry groups will continue to use FLPMA (including WSA's) to their advantage such as they have all over Utah. This second the BLM is being sued in a handful of cases by SUWA persuant to FLPMA and by the CBD to protect the Sage Grouse in the western states. If that happens and the BLM loses in court such as they did with the Tortoise and Nevada... it's going to be a game changer for Utah's west desert public lands.
