Non-native species can wait decades or centuries before spreading
Invasive plants can stay dormant for decades or even centuries after they have been introduced into an environment before rapidly expanding and wreaking ecological havoc, according to a new study led by the University of California, Davis.
The research, published in Nature Ecology and Evolution, looked at more than 5,700 species of invasive plants in nine regions around the globe. It represents the most comprehensive analysis of plant invasions conducted to date, said senior author

Hanson and team battle invasive species
At first glance, Orobanche ramosa looks like an interesting blossoming plant, one that could add a unique flair to flower arrangements. But it's a parasitic weed that attaches to roots, sucks out nutrients and is threatening California's $1.5 billion processing tomato industry.
The weed's tiny seeds — smaller than finely ground pepper — can survive in soil for many decades and be carried by wind, water, soil transfers and even footwear. If found attached to crop plants and reported to the state, farmers are required to destroy the field before harvest, taking large losses not covered by...

Auto emissions 'fertilize' fuel
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...

It all started with pumpkin seeds
Justin Valliere has been hired to expand the Department of Plant Sciences' reach in the fields of invasion and restoration ecology. Valliere started as an assistant professor of UC Cooperative Extension in July.
Valliere seeks ways to restore California's native plant communities amid the onslaught of invasive plants and a range of environmental changes. He thinks it's important to bring youngsters into the research world, training them to care about nature and inspiring them to form the next generation of restoration professionals. Cooperative Extension offers a great way to...
