Introduction:
Pollinator insects are essential to produce many economically and nutritionally important crops grown in the western USA. These crops include blueberries, almonds, sunflowers, cucurbits, and many others. Almond pollination in California plays a vital role in the apiary industry, driving beekeepers to haul huge numbers of bee colonies to California for the few weeks in late winter when almonds bloom. Bees are selective of the pollen and nectar they forage, and diverse floral resources can allow bees to forage according to their nutritional needs (Leponiemi et al. 2023). Planting pollinator habitat in natural areas, gardens, and agricultural land is one method of supporting bee health....

Keep an eye out for this potential problem weed in southern California: Stipa capensis. First reported in 1995 in Riverside, this species is native to the Mediterranean and has established in the Coachella Valley of the Sonoran Desert. It is spreading rapidly in the Palm Springs area, forming dense monocultures. Confirmed reports have recently been made in Borrego Springs and Point Mugu. It has the potential to promote fire in California desert ecosystems and may also suppress native wildflower abundance in the areas it invades.

Wildfire is an important ecological process that shapes patterns of plant diversity in many Mediterranean ecosystems, including California. In coastal sage scrub and chaparral, for example, plant diversity is often highest in the growing seasons immediately after a site burns, with many fire-following species emerging from the soil seed bank and bud bank. This often results in spectacular displays of wildflowers when sufficient rainfall occurs following fire.
In a recent study published in Global Change Biology, however, we found that persistence of these unique, fire-following wildflowers may be threatened by invasive plant species as well as nitrogen...

How can weed control help with wildfire preparedness?
Wildfires are part of California's ecosystems, and they do not have to lead to the destruction of structures and livelihoods. Each of us can contribute to improving wildfire resilience, from individual homeowners and businesses to entire communities. Managing the vegetation and landscape around our homes can play a crucial role in preventing the spread of fires and sources of ignition.
Given the large amount of rain in the winter of 2022-2023, you might have experienced a surge in annual grasses and fast-growing plants that cover most of the ground around your home and community. In my area, I observed invasive species like wild oats and mustard...
