This bill helps ranchers who've lost access to their grazing land due to disasters like wildfires, droughts, or extreme weather. When a rancher's usual grazing area becomes temporarily unusable because of these events, the federal government can now let them use nearby vacant grazing land instead. This is meant to be a temporary solution to help ranchers keep their operations going while their original land recovers.

The bill sets up a flexible system where either the Forest Service (for national forests) or the Bureau of Land Management (for public lands) can approve this temporary use. They'll look at what conditions were on the vacant land before and what conditions are nearby to decide what rules should apply. Ranchers can even put up temporary structures like portable fences and water troughs to make the land work for their animals. The agencies have to coordinate with each other so ranchers can access vacant land regardless of which agency manages it.

Importantly, this temporary arrangement doesn't change anything permanently. Ranchers keep their original grazing rights and can return to their original land once it's usable again. The government has to set up clear guidelines within a year to make this process work smoothly, and they'll regularly check on the health of the vacant lands being used. The goal is to help ranchers survive natural disasters without losing their livelihoods while the land recovers.
