The Giant Sequoias in the Sierra Nevada are one of America’s treasures.  But for the first time in the parks history the trees are showing visible signs of exhaustion due to the drought:  thin and browning leaves. Valley Public Radio’s Ezra David Romero hikes into one of the largest groves of Giant Sequoias and finds a crew of scientists rushing to gather data by scaling the monstrous trees.

Despite enduring a lifetime of oppression, Nelson Mandela transformed his nation by seeking reconciliation with his oppressors rather than retribution. In this week’s edition of The Moral Is, Fresno State Biology Professor Madhusudan Katti wonders whether the power of reconciliation as a moral principle might save us all from the damage humanity is inflicting on our planet and ourselves.


With the passing of Nelson Mandela last month, we lost one of the strongest needles in humanity’s moral compass.

California has more trees now than at any time since the late Pleistocene. And it comes as no surprise to residents of the San Joaquin Valley that our cultivation of trees has played a defining role in shaping the California we know today.

Fires in the Sierra Nevada are a natural phenomenon, but with human sparked blazes - like this summer's Rim Fire - the ecology of the mountain range is in flux. Will the high country scorched this summer ever return to its natural glory or will the region of the forest be littered with shrubbery? In this report Valley Public Radio’s Ezra David Romero takes a walk through multiple groves scorched by fires - caused naturally and by the human hand - and speaks with ecologists about the future of the forest burned by the Rim Fire.

Sacramento-San Joaquin Delta Historical Ecology Study / San Francisco Estuary Institute-Aquatic Science Center / California Department of Fish and Game

A new study released this week by the San Francisco Estuary Institute and the California Department of Fish and Game aims to turn back the clock and learn how the Sacramento-San Joaquin Delta used to work - over 150 years ago.

It's part of an effort to allow scientists to better understand how to restore the Delta, by examining how the massive freshwater estuary functioned, before the gold rush and agriculture transformed the region with levees, shipping channels and dredging.
