Fifty-one Fish and Wildlife Conservation Offices are strategically located across the Nation and play an important role in implementing the Service’s fish and aquatic resource conservation programs. Service staff work with a broad range of partners, and use a variety of non-regulatory conservation tools, to recover and restore some of the Nation’s most iconic fish and other aquatic species and their habitats, many of which are listed as threatened or endangered under the ESA, or are at-risk of listing. These offices are the Service’s “boots on-the-ground” fisheries conservation capacity and are under increasing demand for their services. They are essential components of Service efforts, aligned with Administration priorities, to tackle climate change climate change Climate change includes both global warming driven by human-induced emissions of greenhouse gases and the resulting large-scale shifts in weather patterns. Though there have been previous periods of climatic change, since the mid-20th century humans have had an unprecedented impact on Earth's climate system and caused change on a global scale.
