1,800 Climate-Ready Trees Provided to Residents of Low Shade Neighborhoods
To date, over 1,800 climate-ready shade trees and tips on their planting and long-term care have been provided by UC Master Gardeners and over 20 partners to residents of low shade neighborhoods in San Bernardino and Riverside Counties through the “Trees for Tomorrow Start Today” project. Tree species given away are identified from research projects including the joint University of California/United States Forest Service (USFS) study at UC Riverside as well as from other research, local observations, and input from the green industry and academic colleagues.
Why is this project so important? 95% of Californians now reside in cities and suburban environments. Resulting urban heat islands created by built environments coupled with impacts of climate change can be mitigated through nature-based solutions. Planting climate-ready shade trees now will help ensure cooler urban areas in the next several decades as trees mature and maximize their urban ecosystem benefits. Fortunately, the shade from a single well-placed tree can decrease surface temperatures of black asphalt and artificial turf by more than 70 degrees F in hot inland and desert cities. Studies show that surrounding air temperatures can also be reduced through the transpiration process.
A major goal of the"Trees for Tomorrow Start Today" project is to enhance tree canopy cover in low shade neighborhoods also plagued with much higher than average levels of air pollution and pulmonary and cardiovascular disease incidence. Events over the past month have occurred in Fontana, San Bernardino, and the Salton Sea.
Thank you to all our partners and, especially, our tree recipients, for greening and cooling your yard and neighborhood!
A Presidential Love of Bees: From 'Bee Houses' to 'Bee Trees'
Today, on Presidents' Day, let's buzz back in history to our first President and his love of honey bees. Picture this: George Washington (Feb. 22, 1732-Dec. 14, 1799) is eating hoecakes with honey, and adding honey to his tea, something that historians...

Finding an Ecological Niche: The Gray Pine
[Note: Gray pine (Pinus sabiniana), buckeye (Aesculus californica), and blue oak (Quercus douglasii) are tree species that thrive in rugged local foothill woodland and chaparral habitat. Last edition, we covered the blue oak, and today the gray pine is...
Arnon Dag: How to Improve Cross-Pollination in Almond, Pear, Apple and Cherry Trees
How can you improve cross-pollination in such tree crops as almond, pear, apple and cherry? Senior scientist Arnon Dag of the Agricultural Research Organization, Volcani Institute, Israel, will discuss his research at...

Planting Bare-Root Fruit Trees
There are several advantages to planting bare-root trees: they are usually less expensive, easier for gardeners to transport, and they will grow their roots entirely into native soil (rather than having to transition from potting mix into dissimilar...
