Lake Tahoe Basin Management Unit (TMU - Forest #19) KMB 6-6-4

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 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. The National Forest lands of the basin were consolidated into the new Lake Tahoe Basin Management Unit (LTBMU). 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 within 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. The input tone of each repeater is transmitted on the output frequency.

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."
