Orange Peels in the Forest?

June 10, 2013 Posted by: EH - Park Ranger (Yosemite Valley)

Hiking along a trail in the White Wolf area, to my surprise I saw an orange peel on the forest floor! Did someone litter? No, it wasn’t the discarded shell from a delicious fruit we know well, but a cup-shaped fungus growing upward from the ground.

 

Hetch Hetchy Wildflowers: Species List

June 07, 2013 Posted by: BW & AH - Park Rangers (White Wolf)

Hetch Hetchy is a wonderful place to experience wildflowers early in Yosemite’s summer season. At about 3,800 feet, it is lower in elevation than many other parts of the park–so it’s also one of the first places that flowers bloom in Yosemite. Here is a small sampling of flowers recently seen blooming along the 2.5-mile trail to Wapama Falls.

 

Sierra Mountain Kingsnake

April 23, 2013 Posted by: BR - Park Ranger/Resources Management & Science Liaison

Dangerous snake? It sure is... if you are a lizard, nestling bird, or small mammal. If you are a human being, it is mostly harmless. The Sierra mountain kingsnake (Lampropeltis zonata multicincta), with its rings of white, orange, and black, has to be the most spectacularly colored snake in Yosemite. Some call it the coral kingsnake because of its somewhat similar appearance to the venomous coral snake. Fortunately for Yosemite visitors, the nearest wild coral snake lives in Arizona.

 

Busy Beaver at Mirror Lake

April 09, 2013 Posted by: BW - Volunteer Interpreter

Observant visitors to Mirror Lake over the past month may have noticed evidence of beaver (Castor canadensis) activity. Several cottonwood trees around the main reflection pool are showing the toothmarks of gnawing by beavers.

 

Spring has Sprung Somewhere

March 15, 2013 Posted by: BW - Volunteer Interpreter

Spring in the mountains is a funny thing. Like a wave slowly washing over the Sierra Nevada, spring will crash first onto the foothills and then, following the warmer temperatures, work its way up to the highest peaks in a spray of late summer wildflowers.

 

The Buckeyes are Looking for Spring

February 15, 2013 Posted by: BW - Volunteer Interpreter

The recent warmer temperatures have melted much of the snow in Yosemite Valley, revealing damp ground underneath. One of the things that was uncovered was the fruit of the California buckeye (Aesculus californica), which had fallen to the ground at the end of summer.

 

Winter Wind Valentine

February 15, 2013 Posted by: BW - Volunteer Interpreter

Some travelers to Yosemite this winter may be surprised to find something besides snow in the air. Pollen from the incense cedar (Calocedrus decurrens) is flying far and wide this February.

 

Acorn Woodpecker

January 14, 2013 Posted by: BW - Volunteer Interpreter

One of eleven bird species in the woodpecker family that can be found here, many acorn woodpeckers make a home at the lower elevations of Yosemite National Park. In Yosemite Valley, this is one of the most apparent birds, often making quite a ruckus with loud nasal squawks that could resemble maniacal laughter. Seek out oak woodlands to find these year-round residents.

 

Winter Solstice

December 21, 2012 Posted by: BW - Volunteer Interpreter

With just over nine and a half hours of daylight here at Yosemite National Park, today is the shortest day of the year. This day also marks the lowest point the sun will reach in our daytime sky.

 

Leafy Mistletoe

December 20, 2012 Posted by: BW - Volunteer Interpreter

Now that the California black oaks in Yosemite Valley have dropped most of their leaves, something strange has been revealed among the branches. Even though it is winter, big green leafy clumps of mistletoe are still growing up there.

 

2012 Christmas Bird Count

December 18, 2012 Posted by: BW - Volunteer Interpreter

2012 Christmas Bird Count Last Sunday over 40 enthusiastic birders braved the cold temperatures to participate in the 113th annual Christmas Bird Count. This nationwide event is sponsored by the National Audubon Society and features local groups identifying and counting every bird they see in a given area for one day.

 

Coyote

December 16, 2012 Posted by: BW - Volunteer Interpreter

The fresh layer of snow in the Valley has brought out the coyotes. Several have been spotted over the past few days, roving around in search of food.

 

Rain Beetles

December 01, 2012 Posted by: EW - Park Ranger

These beetles have literally been waiting their entire lives for this moment, this one moment…

 

Birding in Cook’s Meadow

November 26, 2012 Posted by: BW - Volunteer Interpreter

Even though our neo-tropical migrants have flown south for the winter, Yosemite is still a great place to go birding.

 

Bobcat

November 13, 2012 Posted by: BW - Volunteer Interpreter

This large bobcat, which has been regularly sighted around the Valley in the past month, was spotted behind the Rangers’ Club intently stalking some small prey item.

 

Showy Milkweed

November 12, 2012 Posted by: BW - Volunteer Interpreter

The most common milkweed plant in Yosemite Valley is putting on its last show of the season.

 

Did You Know?

Riparian area in Tuolumne Meadows

Riparian communities are adjacent to the river channel and tributaries; they are the interface between the river and surrounding meadow and upland communities. They provide specialized habitat and important nutrients to the meadow and river systems.
