Lake Trout
The apex predator of the deep lake, lake trout can weigh over 30 pounds and live for decades. They inhabit the coldest, deepest water and are prized by anglers. Catch-and-release fishing is encouraged for conservation.

The Ecosystem
The Lake Tahoe basin supports a remarkably diverse ecosystem, from deep-water fish communities to subalpine meadows teeming with wildflowers. The combination of dramatic elevation changes, a large pristine lake, and extensive old-growth forest creates habitat for hundreds of species.
The basin sits within two national forests — the Lake Tahoe Basin Management Unit and the Eldorado and Toiyabe National Forests — providing a protected refuge for wildlife in the midst of a popular recreation area. Conservation programs work continuously to maintain the delicate balance between human recreation and wildlife habitat.
Wildlife viewing is among the most rewarding activities Tahoe offers. Patient observers with binoculars may spot bald eagles soaring above the lake, black bears foraging in meadows, ospreys diving for fish, and enormous mule deer browsing at forest edges — often within sight of the ski runs and beaches.
Hundreds of black bears live in the basin. They are regularly seen near campgrounds and neighborhoods. Never approach or feed them — observe from a safe distance.
A small population of bald eagles overwinters at Tahoe, hunting the lake and streams. The best viewing is between November and March from Emerald Bay and Zephyr Cove.
Tahoe's most commonly sighted large mammal. Herds of mule deer graze the meadows and forest edges at dawn and dusk throughout the year.
These playful mammals have made a comeback in the Tahoe basin. Look for them in the Truckee River and along sheltered shorelines.
In the Lake
The apex predator of the deep lake, lake trout can weigh over 30 pounds and live for decades. They inhabit the coldest, deepest water and are prized by anglers. Catch-and-release fishing is encouraged for conservation.
The native trout of the Great Basin was once the dominant fish in Lake Tahoe. Nearly eliminated by introduced species in the early 20th century, reintroduction programs have brought this beautiful native back to portions of the watershed.
An accidentally introduced species now integral to Tahoe's food web. Mysis shrimp form an important food source for lake trout, but have had complex ecological effects that scientists continue to study.
The Forests
Three primary conifer species dominate the Tahoe landscape, each adapted to slightly different elevations and conditions. Jeffrey pine, with its vanilla-scented bark, anchors the mid-elevation forests. Red fir takes over at higher elevations, forming the dense, snow-heavy forests that hold the deep snowpack skiers depend on.
Western white pine and mountain hemlock grow near timberline, where conditions are harsh and the growing season brief. Aspen groves light up in brilliant gold and orange each October, creating some of the most spectacular autumn color in the Sierra Nevada.
Old-growth forest remains in protected pockets throughout the basin, with trees exceeding 300 years of age. These ancient groves support cavity-nesting birds, rare fungi, and countless species that depend on large, dead wood.
Distinctive vanilla-scented bark. Dominant at 6,000–8,000 ft.
Dense upper-elevation forests that hold Tahoe's deep snowpack.
Brilliant fall color in riparian zones and avalanche paths.
Meadows explode with mule's ear, paintbrush, and lupine each June.
Conservation
Campgrounds throughout the basin require food storage in bear boxes. Bears that become food-conditioned must be removed — please never feed wildlife.
Leaving established trails damages fragile vegetation and disturbs nesting birds. The alpine meadows are particularly vulnerable to trampling.
Aquatic invasive species are a major threat. Clean, drain, and dry all watercraft before entering the lake to prevent spreading Asian clams and other invaders.
