Established by proclamation on May 25, 1907 by President Teddy Roosevelt covering 221,324 acres along the river along the Owens River.  First established to secure the water interests of the City of Los Angeles, the Inyo National Forest has been expanded and contracted at least four times since its creation. Most of the original lands designated as the Inyo National Forest are no longer part of the Forest and are now owned by the Los Angeles Department of Water and PowerThese lands were later returned to the public domain and portions of the Sierra National Forest, east of the Sierra crest as well as the White-Inyo Mountains, were designated as the Inyo National Forest. The forest now covers 2 million acres.  The Inyo National Forest extends 165 miles from Conway Summit in the north and to the Kern Plateau in the southThe Inyo has over 10,500 feet of elevation difference, from 3,900 feet near Owens Lake to 14,494 on the peak of Mt. Whitney, highest peak in the continental United States.

The establishment of Forest Reserves began with the passage of the Forest Reserve Act of 1891, allowing Presidents to establish Forest Reserves by proclamationIn 1899 President William McKinley created the Lake Tahoe Forest Reserve, including the core of the National Forest land in the Tahoe Basin, an area of about 37,000 acres, following the decades of logging for the Comstock mining boom. None of this acreage included any of the shorelineAbout 8 years later three separate forests were developed out of the reserve, the Tahoe, Eldorado and Toiyabe National Forests. Each of these forests extended into the basin and managed separate sections.  
  
The Forest includes the Mono Lake National Forest Scenic Area, Boundary Peak - the highest peak in the State of Nevada at 13,140 feet, the world's largest Jeffrey Pine Forest located east of Mammoth Lakes and south of Mono Lake, 2 Wild & Scenic Rivers, 5 Visitor Centers, 3 Scenic Byways, 2 Alpine Ski Areas and 1 Nordic Ski Center.  The world's oldest tree, Methuselah, is a 4700 year old Bristlecone Pine growing in the Ancient Bristlecone Pine Forest atop the White Mountains. The Inyo has 9 Congressionally designated Wilderness Areas covering more than 800,000 acresAmong them is the John Muir Wilderness, which receives the most visitor use per acre, per year, of any wilderness area in the western United States. The Mt. Whitney trail corridor is the most challenging trail to manage in the National Forest System and has the only day use quota and permit requirement on any National ForestThis land, where the desert meets the mountains, was first reserved for its timber, water and forage. Thanks to decades of public management, the lands of the Inyo National Forest continue to supply clean water to over 3.8 million people, renewable forests, homes for wildlife from Sierra Nevada bighorn sheep to the Golden Trout, and the peace of the outdoors for nearly four million people annually, the most for a National Forest in California.. The Inyo consistently ranks in the top 5 National Forests in the U.S. in recreation use and its developed recreation sites (campgrounds, picnic areas, nature trails interpretive and historical sites, visitor centers, etc) receive the most use of any one National Forest in the country, approximately twice that of the #2 National Forest in this category.

By the mid 1960s nearly 70 years of National Forest management resulted in the acquisition of a significant amount of land added to the public ownershipAcquisition of environmentally sensitive lands is one important way to protect the lakeBy the early 1970s the acreage of publically owned land in the basin had increased from 37,000 acres to 154,000 acres, some of which is located on the lake's shoreline. This additional land was acquired through land exchanges and purchases funded by the Land and Water Conservation Act of 1965.  
  
There are 238,000 acres of old-growth forest on the Inyo National Forest, primarily consisting of  Lodgepole pine (''Pinus contorta'') and Jeffrey pine (''Pinus jeffreyi'').
+
In 1973, this most unique area of America's National Forest System was established.  The establishment of the Lake Tahoe Basin Management Unit (LTBMU) was not really the creation of a "new" National Forest, but rather an administrative re-organization of National Forest lands that had already existed in the Tahoe Basin since 1899.  Up until the unit was created, the management of National Forest land was split up between 3 ranger districts, the Lake Valley (Eldorado), Truckee (Tahoe) and the Carson (Toiyabe) Ranger Districts, on 3 National Forests, the Eldorado, Tahoe and Toiyabe National Forests, in 2 different Forest Service regions, the Pacific Southwest Region (R5) headquartered in Vallejo and the Intermountain Region (R4) headquartered in Ogden, Utah.  The pressures of growth, increased recreation use and water quality degradation in the basin created significant issues that made coordination between the 3 units difficult, if not impossible, and at the least inefficient.  The National Forest land in the basin needed one voice.  A decision was made by the Forest Service to administratively place the basin portion of these 3 units under a one Forest Supervisor and call this consolidated organization the "Lake Tahoe Basin Management Unit."  The name "Lake Tahoe Basin Management Unit" was originally a temporary one, but after 4 decades, the name remains.  Several attempts have been made since to establish the "Lake Tahoe National Forest," but a bill doing such has never passed.  The boundaries of this unit follow the watershed boundaries of the upper Truckee River and Lake Tahoe, which is the crest of the ridge around the lake, with a short gap where the Truckee River flows down canyon from the lake.
  
The forest is divided into the Mono Lake (District 1), Mammoth (District 2), White Mountain (District 3) and Mt. Whitney (District 4) Ranger Districts with the Forest Supervisor's Office in Bishop.
+
The LTBMU is responsible for the conservation, preservation and restoration of the Lake Tahoe watershed ecosystem on National Forest lands. Projects and programs also include habitat, fire management, and urban lot management. Additionally the LTBMU provides and maintains high quality recreational opportunities for millions of visitors and residents annually.
  
 +
Compared to other National Forest land the LTBMU is small, yet it is the Tahoe Basin's largest land manager, responsible for 78% of basin lands. As such the Forest Service has the largest single role in ecosystem and watershed management and protection. The LTBMU is a part of the National Forest System, yet is managed somewhat differently than other National Forests. Many common forest activities such as mining, grazing or timber harvesting are either not a part of LTBMU management or play a very small role. Since the lake is so dependent on all that happens around it, LTBMU programs manage the whole of the basin as a complete inter-dependent system.  The LTBMU is a unique inter-mix of forest and urban communities, presenting challenges and complexities few other National Forests experience. Since its establishment in 1973, the LTBMU has become a pioneer and leader in the science of forest and ecosystem management. The work of the Forest Service supports and is supported by many partners. Other federal, state and local agencies are working together in the effort to face challenges, conserve and restore natural and cultural resources, and enhance the recreational values of the Lake Tahoe Basin.
  
 +
The purchase of sensitive parcels of private land for public ownership is more important than ever.  In December of 1980 the Santini-Burton Act passed, which places the revenue from the sale of federal land in the Las Vegas Valley into a fund for land purchases and watershed restoration in the Lake Tahoe basin. Land in individual urban lots began to be purchased and to date, over 3,500 parcels (or Urban Lots) totaling 13,000 acres valued at $105 million have been acquired.  As of 2014 National Forest land ownership has increased to 160,000 acres with 18% of the 72 miles of shoreline now part of the LTBMU.

Old growth forest in the Lake Tahoe Basin is rare due to extensive logging that supplied the Comstock mines with bracing for shafts, fuel and building materialAbout 5,400 acres are left, less than 3% of the land in the basin, consisting of Jeffrey pine (''Pinus jeffreyi''), White Fir (''Abies concolor''), Red Fir (''Abies magnifica''), Sugar pine (''P. lambertiana'') and California incense cedar (''Calocedrus decurrens'').

There are no ranger districts dividing this "forest,"  the LTBMU is headed by a Forest Supervisor, with the Forest Supervisor's Office in South Lake Tahoe.

The Inyo National Forest has 3 nets, Forest Net - North, Forest Net - South and Service Net.  The Mono Lake and Mammoth Ranger Districts are on the North Net.  The White Mountain Ranger District uses the North Net for those areas north of the bottom of the Sherwin Grade on U.S. 395 (McGee and Rock Creek Canyons and the Casa Diablo area east of Crowley Lake) and the South Net south of that point (Buttermilk Country, Bishop Creek and Big Pine Creek to Division Creek as well as the White Mountains (Westguard Pass north).  The Mt. Whitney District uses the South Net only (from Division Creek south to the Kern Plateau and the Inyo Mountains - south of Westguard Pass).  Some areas of Bishop Creek and the north end of the White Mountains are covered by Glass Mountain only (Tone 3) and are exceptions to this North Net/South Net configuration.  Silver Peak, northeast of Bishop in the White Mountains is the only electronic site with repeaters on all 3 nets and is the location of the North Net remote base. The South Net remote base is on Mazourka Peak northeast of Independence.  The links for the remote bases utilize UHF only.  The Inyo National Forest does not have direct, or simplex channels provided for its 3 Nets. 
+
The LTBMU has a Fire Net and Admin Net.  There are channels provided enabling direct or simplex communication on each net.  The location and number of remote bases is unknown or how the dispatch center in Camino controls the two nets.

The Inyo National Forest fire organization is combined with the Bureau of Land Management (BLM) Bishop Field Office fire organization into one Interagency Fire Management Organization. The management area combines the public land of the Inyo National Forest and Bishop Field Office in Inyo and Mono Counties in California and part of Mineral and Esmeralda Counties in Nevada, covering over 2 million acres.  The Interagency Fire Management Organization maintains 8 fire stations with 9 engines, 7 fire prevention patrol units, 2 water tenders, a 10-person fire use management hand crew, a 20-person hotshot crew, an air tanker reload base and a helitack base.  This organization, as well as the non-fire management personnel of both agencies, use the two Inyo National Forest nets for its primary nets.  The BLM net is used as an alternate dispatch or command net when multiple fire starts/large incidents occur.   
+
The unit identifier system for non fire personnel is unknown.  As there are not any ranger districts on this "forest" many identifiers, for an unknown reason, begin with the number 4.  There are 3 fire stations on the LTBMU, Meyers, William Kent and Spooner Summit. In the last 10 years the the LTBMU has been dispatched by the interagency dispatch center in Minden and the Tahoe National Forest-Cal Fire Nevada-Yuba-Placer Unit Emergency Command Center at Grass Valley.  The LTBMU is now dispatched by the Cal Fire - Eldorado NF co-located communications center in Camino, just east of Placerville.  The center's identifier is "Camino."  
  
In Mono County the wildland fire State Responsibility Area (SRA) inside the Inyo National Forest is in the direct protection area of the Inyo National Forest. This is provided under contract and the state pays the USFS for this service.  The SRA outside the National Forest boundaries in Mono County is in the direct protection area of the BLM.  In exchange the BLM land in Inyo County is in the direct protection area of Cal Fire's San Bernardino Unit, Owens Valley Division.
 
 
The unit identifiers follow the '''function name''', district number, position number system. Employees working in or out of the Supervisor's Office use identifiers have a "5" following the function name.  The Owens Valley Interagency Dispatch Center is located in the joint Inyo National Forest-BLM Bishop Field Office facility in Bishop.  It also provides dispatch for the BLM Central California District - Bishop Field Office. This center provides dispatching for two National Park Service units:  Devils Postpile National Monument and the Manzanar National Historic Site.  Law enforcement dispatching for Devils Postpile is provided by Yosemite National Park using  a link to its law enforcement net located on Mammoth Mountain. This center is not a 24 hour operation, but is open 7 days per week, year long.  When the Owens Valley Center is shut down the San Bernardino Federal Interagency Communications Center ("San Bernardino") provides dispatching as it is able to control the entire Inyo/BLM radio system. The center's identifier is "Inyo."

(From: US Forest Service - Lake Tahoe Basin Mgmt Unit (CA/NV) )

US Forests in California:

Eldorado Lake Tahoe BMU Mendocino San Bernardino Sierra Tahoe


Lake Tahoe Basin Management Unit (TMU - Forest #19) "Camino" KMB 6-6-0

The establishment of Forest Reserves began with the passage of the Forest Reserve Act of 1891, allowing Presidents to establish Forest Reserves by proclamation. In 1899 President William McKinley created the Lake Tahoe Forest Reserve, including the core of the National Forest land in the Tahoe Basin, an area of about 37,000 acres, following the decades of logging for the Comstock mining boom. None of this acreage included any of the shoreline. About 8 years later three separate forests were developed out of the reserve, the Tahoe, Eldorado and Toiyabe National Forests. Each of these forests extended into the basin and managed separate sections.

By the mid 1960s nearly 70 years of National Forest management resulted in the acquisition of a significant amount of land added to the public ownership. Acquisition of environmentally sensitive lands is one important way to protect the lake. By the early 1970s the acreage of publically owned land in the basin had increased from 37,000 acres to 154,000 acres, some of which is located on the lake's shoreline. This additional land was acquired through land exchanges and purchases funded by the Land and Water Conservation Act of 1965.

In 1973, this most unique area of America's National Forest System was established. The establishment of the Lake Tahoe Basin Management Unit (LTBMU) was not really the creation of a "new" National Forest, but rather an administrative re-organization of National Forest lands that had already existed in the Tahoe Basin since 1899. Up until the unit was created, the management of National Forest land was split up between 3 ranger districts, the Lake Valley (Eldorado), Truckee (Tahoe) and the Carson (Toiyabe) Ranger Districts, on 3 National Forests, the Eldorado, Tahoe and Toiyabe National Forests, in 2 different Forest Service regions, the Pacific Southwest Region (R5) headquartered in Vallejo and the Intermountain Region (R4) headquartered in Ogden, Utah. The pressures of growth, increased recreation use and water quality degradation in the basin created significant issues that made coordination between the 3 units difficult, if not impossible, and at the least inefficient. The National Forest land in the basin needed one voice. A decision was made by the Forest Service to administratively place the basin portion of these 3 units under a one Forest Supervisor and call this consolidated organization the "Lake Tahoe Basin Management Unit." The name "Lake Tahoe Basin Management Unit" was originally a temporary one, but after 4 decades, the name remains. Several attempts have been made since to establish the "Lake Tahoe National Forest," but a bill doing such has never passed. The boundaries of this unit follow the watershed boundaries of the upper Truckee River and Lake Tahoe, which is the crest of the ridge around the lake, with a short gap where the Truckee River flows down canyon from the lake.

The LTBMU is responsible for the conservation, preservation and restoration of the Lake Tahoe watershed ecosystem on National Forest lands. Projects and programs also include habitat, fire management, and urban lot management. Additionally the LTBMU provides and maintains high quality recreational opportunities for millions of visitors and residents annually.

Compared to other National Forest land the LTBMU is small, yet it is the Tahoe Basin's largest land manager, responsible for 78% of basin lands. As such the Forest Service has the largest single role in ecosystem and watershed management and protection. The LTBMU is a part of the National Forest System, yet is managed somewhat differently than other National Forests. Many common forest activities such as mining, grazing or timber harvesting are either not a part of LTBMU management or play a very small role. Since the lake is so dependent on all that happens around it, LTBMU programs manage the whole of the basin as a complete inter-dependent system. The LTBMU is a unique inter-mix of forest and urban communities, presenting challenges and complexities few other National Forests experience. Since its establishment in 1973, the LTBMU has become a pioneer and leader in the science of forest and ecosystem management. The work of the Forest Service supports and is supported by many partners. Other federal, state and local agencies are working together in the effort to face challenges, conserve and restore natural and cultural resources, and enhance the recreational values of the Lake Tahoe Basin.

The purchase of sensitive parcels of private land for public ownership is more important than ever. In December of 1980 the Santini-Burton Act passed, which places the revenue from the sale of federal land in the Las Vegas Valley into a fund for land purchases and watershed restoration in the Lake Tahoe basin. Land in individual urban lots began to be purchased and to date, over 3,500 parcels (or Urban Lots) totaling 13,000 acres valued at $105 million have been acquired. As of 2014 National Forest land ownership has increased to 160,000 acres with 18% of the 72 miles of shoreline now part of the LTBMU.

Old growth forest in the Lake Tahoe Basin is rare due to extensive logging that supplied the Comstock mines with bracing for shafts, fuel and building material. About 5,400 acres are left, less than 3% of the land in the basin, consisting of Jeffrey pine (Pinus jeffreyi), White Fir (Abies concolor), Red Fir (Abies magnifica), Sugar pine (P. lambertiana) and California incense cedar (Calocedrus decurrens).

There are no ranger districts dividing this "forest," the LTBMU is headed by a Forest Supervisor, with the Forest Supervisor's Office in South Lake Tahoe.


RADIO SYSTEM

The LTBMU has a Fire Net and Admin Net. There are channels provided enabling direct or simplex communication on each net. The location and number of remote bases is unknown or how the dispatch center in Camino controls the two nets.

Other

The unit identifier system for non fire personnel is unknown. As there are not any ranger districts on this "forest" many identifiers, for an unknown reason, begin with the number 4. There are 3 fire stations on the LTBMU, Meyers, William Kent and Spooner Summit. In the last 10 years the the LTBMU has been dispatched by the interagency dispatch center in Minden and the Tahoe National Forest-Cal Fire Nevada-Yuba-Placer Unit Emergency Command Center at Grass Valley. The LTBMU is now dispatched by the Cal Fire - Eldorado NF co-located communications center in Camino, just east of Placerville. The center's identifier is "Camino."
