The repository of Bear news, research, and stories we come across.

I've written about my experiences with High Sierra Black Bear Behavior in the Trail and Camp Skills section of the Trail Guide. Remember, bears act differently in different locations, and can be quite unpredictable in most situations.

Most times we can figure out what they want, and that typically boils down to two things: Food, and/or to be "left alone." Bears have personalities and feelings, which make them almost as unpredictable as that most deadly of beasts, humans. Almost...

What to do about bear/human conflict hot-spots found in new study?

BEARS

How to Get Along with Bears

A black bear playbook: Conservationists predict bear/human conflict hot-spots in new study,
Wildlife Conservation Society, October 26, 2018.

MAIN POINTS

"...uses long term data on bear mortality to map high-probability hot-spots for human-bear conflicts."

"...to understand the impact of an increasing human footprint on American black bears at the wildland-urban interface."

Bear Mortality
"...looked at expanding bear populations in the Lake Tahoe Basin and Western Great Basin Desert in Nevada, examining 382 bear deaths between 1997 and 2013. They found that the largest causes of mortality were vehicle collisions (160) and management removal of bears (132) due to animals breaking into people's homes and/or causing property damage, or other threats to human safety."

Score

382 bear deaths,    16 per year

Road Kill #1            10 per year

Urban Kill #2            8 per year

Bear Sign: East Carson River is Bear Country

I've seen bears and bear sign here as long as I've been coming here.

Bear behavior has been on a long term trend of increasing familarity with humans, and increasing numbers for the past couple of decades.

Then Vic Bergstrom sold the Little Antelope Pack Station to Joe. Joe's opened up the bear hunting in the Eastern Sierra around the East Carson River. This has changed the trajectory of bear behavior as well as their distribution.

This is a general post about bear encounters on the trails and in the terrain around the upper reaches of the East Carson River.

Bear Track: Dorothy Lake

Bear Tracks just South of Dorothy Lake Pass.

Hiking along the Pacific Crest Trail on the South side of Dorothy Lake at the very top of Jack Main Canyon.

Yosemite National Park, just South of Dorothy Lake Pass where we entered the park. 

I decided to hike East a bit to check out the little unnamed lake a bit South of Dorothy Lake, and inspected the dried out little ponds that dot the meadow. 

I found a bunch of tracks, and the most prominent were the bear tracks.

Bear, Black, Tracks, High Sierra, Carson Iceberg Wilderness

Bear, Black, Tracks, High Sierra, Carson Iceberg Wilderness 

April 24, 2004

Bear Tracks standing above snow level, East Fork of the Carson River.

 The weight of the walker, in this case a bear, compresses the snow as they pass, leaving tracks.

As the snow mass melts the compressed snow creating the tracks melts much slower than the surrounding snow, pushing the tracks above the receeding snow.

Bear Behavior: Mum, the bear is eating me & NOLS attack

This rather morbid story is out of Sibera via Australia, and describes Brown Bear behaviors which are totally unheard of in the Sierra Nevada. 

But this violent behavior is not unknown in Black Bears in Alaska, and by hungry or scared Brown Bears anywhere.

It's good to know as much as we can about our furry friends. This facinating research enhances our knowledge about bear phisiology, which may also explain why bears are cranky in Spring: It takes them weeks to fully wake up!
