Goshawks have long been a part of the Lake Tahoe Basin ecosystem. They live at the lake year-round and breed from lake level to tree line.

Nationally Known Research

Current potential stressors to goshawks include urbanization, motorized and non-motorized recreation on forest trails and roads, felling trees for fire reduction, and ski resort-related development.

Development and recreation plans must ensure the species is protected by interfering as little as possible with identified nesting and hunting sights. Marmots are active during the day and are omnivores. Mountain Yellow-legged Frog Mountain Yellow-legged Frog Although the higher elevation smaller lakes and tributaries to Lake Tahoe have historically been ideal habitats for the mountain yellow-legged frog, the introduction of non-native fish species over the past century have threatened the frogs through predation.

They survive in only 20 percent of their historic habitat. You may spot one of these amphibians by noticing the yellow or orange underside of their legs and bodies.

Forest Service has recently tried to reintroduce the yellow-legged frog to lakes in several wilderness areas, including lakes Tamarak, Cagwin, Ralston, Lucille, Margery, Jabu and LeConte. Mountain Whitefish Mountain Whitefish The mountain whitefish is a trout-like, silver to dusty green fish found in Lake Tahoe.

Mountain whitefish are members of the salmon and trout family and can be found in lakes, rivers, and streams throughout the Northwest United States. The Lake Tahoe population of mountain whitefish represents the southwestern distribution of the species.

The mountain whitefish spawn from October to December and hatches occur in the early spring. The oldest recorded mountain whitefish was 18 years old, but the typical lifespan is 8 to 9 years. In Lake Tahoe, mountain white fish can be caught throughout the winter months and are tasty to eat.

Pika live at cooler high elevations because they are sensitive to warm temperatures. Climate change is a serious threat to these animals because as temperatures rise in the Tahoe area, the pika will have nowhere higher or cooler to go.

Although pika look like rodents, they are actually a type of rabbit. The snow plant does not contain chlorophyll like most green plants, which can be seen in its bright crimson color. Sugar Pine Sugar Pine The sugar pine has the largest cone of any conifer species, with cones up to 26 inches long.

The Scripps Oceanography and UC Davis Tahoe Environmental Research Center team filtered water from three lakes within the Lake Tahoe basin to collect molecules dissolved in the water.

“The Basin provides habitat for more than bird, animal and fish species, and more than a thousand different plant species. Included are 16 species of imperiled wildlife—the endangered bald eagle and peregrine falcon, the osprey, goshawk and spotted owl, and the once abundant Lahontan cutthroat trout, now extinct in the lake and just recently reintroduced in the basin.”.
