Pest Management & Plant Health

If you lived in Marin prior to 1988 you remember a time when the only turkeys you saw were at the grocery store. This is because, in 1988, the California Department of Fish and Wildlife introduced wild turkeys onto Loma Alta hill on the west side of Lucas Valley.

In the last week, we have highlighted some invasive species that damage and threaten California's natural resources. If you missed any of our posts, click on the species listed below.

Brooms are shrubs which were originally planted in California as ornamentals and for erosion control, but are now considered to be invasive weeds since they are highly competitive. They crowd out native plants and form impenetrable barriers to wildlife.

Nutria are found near rivers, streams, lakes, ponds and wetlands. Their burrowing and feeding on vegetation can cause damage. In addition, they can carry pathogens and parasites.

Small beetles are causing big problems in Southern California. Two closely related species, the polyphagous shot hole borer and the Kuroshio shot hole borer (collectively referred to as invasive shot hole borers), have been attacking more than 60 species of trees.

UC IPM agrees that Black lives matter, and that we must act now to end the systemic racism that allows police violence to take Black lives, including George Floyd, Breonna Taylor, Tony McDade, Stephon Clark, Darell Richards, Marshall Miles, Joseph Mann, Atatiana Jefferson, Sandra Bland, and countles...

While some may find them cute, both the Eastern gray squirrel (Sciurus carolinensis) and the Eastern fox squirrel (S. nigeri) are actually invasive species in California. They are two of four species of tree squirrels found throughout the state.

Stink bugs are common pests in gardens but the brown marmorated stink bug, or BMSB, is of particular concern. BMSB (Halyomorpha halys) was first detected in Los Angeles County in 2006 and has since been detected in many other parts of California with large populations in some counties.
