Bureau of Land Management
http://www.blm.gov/wo/st/en.html
The Bureau of Land Management (BLM) is also an agency under the Department of the Interior, like the Parks Department. President Harry S. Truman created the Bureau of Land Management back in 1946 by combining two existing agencies: the General Land Office and the Grazing Service. The BLM currently administers more than 247.3 million acres of public lands in the United States. Most BLM public lands are located in these 12 western states: Alaska, Arizona, California, Colorado, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, Washington and Wyoming.
BLM managed lands were often originally described as land that “nobody wanted” because they had been passed over by early ranchers and settlers. However, the federal government found value in these lands for not only their beauty and the preservation of nature, but for the subsurface mineral rights that existed under federal properties. The agency manages over 200 wilderness areas, 23 national monuments and some 636 other federally protected areas as part of the National Landscape Conservation System totaling about 30 million acres.
The BLM had been in the news over the past couple of years, due to conflicts with some local ranchers that have been leasing lands from the federal government. Some of these conflicts have escalated to armed confrontations. The Bureau of Land Management also assists in wildfires that threaten federal ands, but you will often hear them assisting state and local fire fighting efforts when needed. Here are some of the federal VHF and UHF frequencies that are allocated to Bureau of Land Management operations across the United States:

National Park Service
https://www.nps.gov/index.htm
The National Park Service (NPS) is an agency of the Department of the Interior that manages all National Parks and some National Monuments. The Park Service will be celebrating its 100th birthday soon, as they were officially formed on August 25th, 1916. Today, the NPS has over 20, 000 employees and manages over 400 parks, monuments, memorial or other units.
The NPS has quite a number of VHF and UHF frequencies that are available for use as part of the Department of the Interior allocations. While most National Parks are still using analog radios, they are likely in the process of upgrading to APCO P-25 digital mode over the next few years. Some parks have already switched to digital mode. And most National Parks will have multiple repeaters as well as simplex channels that can be used around the park property.
Here is a listing of potential target frequencies that may be in use at any properties managed by the National Park Service. I have included the Park Service older VHF low band allocations, which actually may still be in use by some of the smaller, more rural properties:

Most of the UHF frequencies listed are likely used for point-to point data links for remote control or linking of VHF repeater sites. Back in 2009 I reported on a group of UHF frequencies that had federal monitors in the Northern Virginia area flummoxed. The frequencies heard were 408.2250, 408.2750, 408.4625, 408.5250, 408.5375, 408.6250, 409.0500, 417.2750, 417.4625 and 417.5250 MHz. Listeners thought they appeared to be part of a digital trunked system, but all the channels appeared to be keyed up full time with a digital format that no one could decode. There were many suggestions as to what super-secret federal or military agency this system belonged to and what they were up to.
These frequencies are, in fact, part of the National Park Service radio network serving Shenandoah National Park. These UHF frequencies are links carrying multiplexed voice and control data to the VHF repeater sites located around the area, and since they are located in high, mountainous areas, they can be received at great distances. Although they are digital, they are not in the APCO Project 25 format that scanners can receive.
US Fish and Wildlife Service
The United States Fish and Wildlife Service (USFWS or FWS) is a U.S. federal government agency within the U.S. Department of the Interior which oversees the management of fish, wildlife, and natural habitats in the United States.
Among the responsibilities of the USFWS are enforcing federal wildlife laws; protecting endangered species; managing migratory birds; restoring nationally significant fisheries; conserving and restoring wildlife habitats, such as wetlands; helping foreign governments in international conservation efforts; and distributing money to fish and wildlife agencies of U.S. states.
The majority of fish and wildlife habitats are on state or private land not controlled by the United States government, so they can sometimes be heard on state or local wildlife agency frequencies.
