HEBER, Ariz. — A federal judge has limited a preliminary injunction to the Sitgreaves National Forest, ruling it no longer applies to the Apache National Forest after determining the challenged U.S. Forest Service actions were confined to the Sitgreaves. The ruling came days after the Center for Biological Diversity sought to intervene, arguing in court filings that unauthorized free-roaming horses had denuded portions of federally designated critical habitat for the endangered New Mexico meadow jumping mouse on the Apache National Forest.
