sage grouse.
i could see an argument made about migration corridors, being that they rely on intact and unfragmented habitat.
Tremendous collaborative efforts were made across state lines, agency and special interest boundaries over the last 2 decades; to prevent ESA listing of sage grouse. Whether listing would have ultimately helped the species and habitat more, the threat of listing resulted in an expensive, extensive regional agreement.
Which Trump erased.
Lawsuit challenges Trump administration reversal of greater sage-grouse protections

The Trump administration is being sued after rolling back protections for the greater sage-grouse in eight western states, a move that opened up critical sagebrush habitat for energy and mineral development.
A coalition of conservation groups filed
a lawsuit against the Bureau of Land Management Monday for approving a management plan in December that reversed a decade-long protection plan that limited oil and gas drilling, mining, transmission lines and other heavy industry within prime sage-grouse habitat.

That’s largely due to habitat loss exacerbated by drought, increasing wildfires and the spread of invasive species. Most greater sage-grouse breeding grounds have a 50% chance of disappearing over roughly the next six decades, according to USGS.
The rare bird has been eligible for some Endangered Species Acts protections since the early 2010s. However, in 2015 the BLM and Forest Service – which manage over half of the bird’s remaining habitat – implemented a management plan that aimed to avoid listing the bird and reverse the species’ decline without impinging on the oil and gas industry and agriculture.
The lawsuit, filed in U.S. District Court in Montana, argues that in reversing the 2015 plan, the Trump administration violates several federal laws by disregarding the best available science showing that expanded oil and gas and other development will cause sage grouse populations to decline.
Griz, wolves and sage grouse are examples of the legal and political maneuvering revolving around the ESA.
Overview of the issue The TRCP has been on the front lines of sage grouse conservation for years. The decline of this iconic game bird of the American West indicates that sagebrush habitat is in trouble, and we care because sagebrush ecosystems are home to more than 350 different species of...
