Manzanita Bee in Trouble

Climate change linked to potential population decline in bees,
Northwestern University, June 28, 2018.

"...climate change may drive local extinction of mason bees in Arizona and other naturally warm climates."

"In a two-year, in situ field experiment that altered the temperature of the bees' nests to simulate a warmer, future climate, 35 percent of bees died in the first year and 70 percent died in the second year. This is compared to a 1-2 percent mortality rate in the control group."

"This species of mason bee (Osmia ribifloris), often called the "blueberry mason bee," is native to the western United States and northern Mexico. This particular type of solitary bee builds nests inside of holes and cracks in dead tree stumps. Yet, as a primary pollinator of manzanita shrubs in the wild, this little-studied bee may have a big effect on its ecosystem."

Into the Manzanita

NORTH SIERRA

Tahoe to Yosemite Trail into Summit City Creek's Canyon

(The manzanita really begins when we drop off the end of Summit City's Canyon descending down into the manzanita lining the canyon of the North Fork of the Mokelumne River.) We've left the lodgepoles far behind, dropped through the firs, and are now into the heat of the pondarosa pines surrounded by manzanita.

And, we're sweating it... searching for fun in deep, dark, almost untracked, forests.
