Preserve in Florida, were created specifically for ORVs and related purposes. However, such designations have not prevented damage or abuse of the policy. Public statements In 2004, several environmental organizations sent a letter to Dale Bosworth, Chief of the United States Forest Service, and described the extent of damage caused by ORV use, including health threats to other people: It is well-established that the proliferation of off-road vehicle and snowmobile use places soil, vegetation, air and water quality, and wildlife at risk through pollution, erosion, sedimentation of streams, habitat fragmentation and disturbance, and other adverse impacts to resources. These impacts cause severe and lasting damage to the natural environment on which human-powered and equestrian recreation depends and alter the remote and wild character of the backcountry. Motorized recreation monopolizes forest areas by denying other users the quiet, pristine, backcountry experience they seek. It also presents safety and health threats to other recreationists. In 2004 the Supreme Court Justice Antonin Scalia listed several problems that result from ORV use in natural areas. From the Environmental News Service article: Scalia noted that off-road vehicle use on federal land has "negative environmental consequences including soil disruption and compaction, harassment of animals, and annoyance of wilderness lovers. A number of environmental organizations, including the Rangers for Responsible Recreation, are campaigning to draw attention to a growing threat posed by off-road vehicle misuse and to assist overmatched land managers in addressing ORV use impacts. These campaigns in part have prompted congressional hearings about the growing impact of unmanaged off-road vehicle use. The House Natural Resources Committee Subcommittee on National Parks, Forests and Public Lands held an oversight hearing on "The Impacts of Unmanaged Off-Road Vehicles on Federal Land" on March 13, 2008. A second hearing on off-highway vehicle (OHV) management on public lands was held by the Senate Energy and Natural Resources Committee on June 5, 2008. The Senate committee hearing was convened for the purpose of finding out why the agencies are failing to grapple with the negative impacts of off-road vehicle use on US public lands and what the agencies might need to start doing differently. For the first time in perhaps a decade, members of the Senate Energy and Natural Resources Committee grilled leaders of the Forest Service and the BLM about why off-road vehicle use is being allowed to damage America's national treasures. Taking center stage in the discussion was the
