Light irrigation before flooding stimulates microbes to remove nitrates from soil
With California enduring record-breaking rain and snow and Gov. Gavin Newsom recently easing restrictions on groundwater recharge, interest in “managed aquifer recharge” has never been higher. This process – by which floodwater is routed to sites such as farm fields so that it percolates into the aquifer – holds great promise as a tool to replenish depleted groundwater stores across the state.

Considering the recent news coverage regarding tree mortality in California, we want to instead view this subject through a lens of hope. For it's not just the news outlets witnessing the extent of forest die-off: children, especially those in forested communities, are seeing the effects of drought, wildfire, and fire suppression policies in real time.
Project Learning Tree is a national education program leading the next generation to witness and then act on these changes. Children are the future of our forests, and we think the efforts of Project Learning Tree are a...

Ibrahim Yaaseen, member of the Palos Verdes Peninsula (PVP) 4-H club, grabs a hard hat and places it on top of his head. He then reaches for a bright orange safety vest and goggles to complete his safety gear outfit before joining the rest of his club members who are dressed the same.
The 4-H Youth Development Program of Los Angeles is already thinking about the future of water management and turned to the West Basin Municipal Water District in El Segundo to gain a deeper understanding of the precious resource we often take for granted.
The University of California 4-H Youth...

Pathogen native to U.S. but had not infected pines until recently
Fungal pathogens that cause die-back in grape, avocado, citrus, nut and other crops has found a new host and is infecting conifer trees causing pine ghost canker in urban forest areas of Southern California.
The canker can be deadly to trees.
Scientists from University of California, Davis, first spotted evidence that the pathogens had moved to pines during a routine examination of trees in Orange County. Over four years, they found that more than 30 mature pines had been infected in an area of nearly 100 acres, according to a
