"A bog is a wetland that accumulates peat, a deposit of dead plant materialoften mosses, and in a majority of cases, sphagnum moss."--Wikipedia. Not so with the Biological Orchard and Gardens (BOG) on the University of California, Davis, campus.

People in urban and suburban areas often use the term invasive to describe plants or weeds that appear to take over a garden or landscape. However, true invasive plants are weeds that infest ecosystems, rangelands, and pastureplaces common garden weeds don't thrive.

The Anise Swallowtail, Papilio zelicaon, fluttered into our pollinator garden and headed straight for the Verbena. Art Shapiro, distinguished professor of evolution and ecology at the University of California, Davis, identified the gender: "it's a girl.

As part of our coverage of California Invasive Species Action Week, today we focus on a pair of invasive species that work together: an insect called the Asian citrus psyllid and the plant disease it can spread, huanglongbing.

Did you know that every 60 days, a new and potentially damaging invasive species enters California? California residents can help in the fight against invasive species by learning and participating next week (June 2-10) in the California Invasive Species Action Week.

Low-lying morning clouds in Southern California coastal areas form the predictable "June Gloom" in early summer - at least, they used to.

"It ain't so much the things we don't know that get us into trouble, it's the things we do know that just ain't so."--American humorist Artemus Ward (1834-1867).

It was billed as the second annual Butterfly Summit, hosted last Saturday by Annie's Annuals and Perennials in Richmond. But a yellow-faced bumble bee, Bombus vosnesenskii, foraging on Anchusa azurea (a member of the borage family), apparently didn't like the focus on butterflies.
