The free iNaturalist app is an online social network of people sharing biodiversity information to help each other learn about nature. Available for android, iPhone, and by a website, iNaturalist is a joint initiative by the California Academy of...

A USDA grant will allow a group of California organic farmers to team up with researchers from the University of California, Chico State and Fresno State to determine whether tilling less soil on the farm will improve production of vegetable crops.

The aim is to duplicate the soil environment found in natural areas – typically concealed by plants, leaves and other organic debris – to improve agricultural soil health, increase production, reduce water use and avoid leaching nutrients out of the root zone.

“Tilling the soil is common on farms, but our research shows that it often isn't necessary, and can even be detrimental,” said Jeff Mitchell, UC...

Many common street trees now growing in the interior of California are unlikely to persist in the warmer climate expected in 2099, according to research published in the July 2018 issue of the journal Urban Forestry & Urban Greening.

“Urban foresters in inland cities of California should begin reconsidering their palettes of common street trees to prepare for warmer conditions expected in 2099 due to climate change,” said the study's co-author, Igor Lacan, UC Cooperative Extension environmental horticulture advisor in the Bay Area.
