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...

Joshua trees burning in the Mojave Desert are the victims of changing patterns of wildfire, fueled by the spread of grasses that are not native to the region, restoration ecologist Justin Valliere told media in recent interviews.
In late July, Valliere was still settling into his new job at the Department of Plant Sciences when the York Fire erupted in the Mojave National Preserve in southern California. The area includes the western range of the Joshua tree, a unique type of yucca that has...

New research published in PNAS (Fusco et al 2019) highlights the role of invasive grasses in creating new wildfire regimes at not just local but regional scales. Weed scientists are familiar with the concept of the grass-fire cycle (D'Antonio and Vitousek 1992): exotic grass invasions promote hotter or more frequent fires, which in turn facilitates more extensive grass invasion, causing more fires, etc. Perhaps now is the right time to better educate non-scientists about this critical concept as wildfires take up more of the public's...

The global horticultural trade in ornamental plants is well known to be a primary source of non-native invasive plant introductions worldwide. In the United States, non-native species make up as much as 80% of the ornamental nursery stock and account for most nursery revenue. Although only a small percentage of these species escape cultivation and become invasive, the large number and diversity cultivated, especially in California, results in ornamental plants contributing to more than half of the invasive weeds currently damaging California's wildlands and remnant natural areas in urban landscapes.
The majority of ornamental plants are purchased and grown by the public. Thus, educating consumers to make informed choices towards...

When wildfires burn in California, people often call them forest fires or brushfires, but the odds are high that an invasive weed is an unrecognized fuels component, says a UC Agriculture and Natural Resources scientist.
“We have all of the nasty non-native Bromus species here in California, and these weeds are key drivers of increasing fire frequency,” said Travis Bean, UC Cooperative Extension weed science specialist based at UC Riverside.
The invasive, non-native Bromus species aggressively outcompete native plants, forming dense stands that grow fast and dry out quickly, becoming highly flammable. Fire can move...
