This week, we put the spotlight on invasive species and how these non-native plants, animals, and pathogens damage California's economy and environment.
You Can Make a Difference
Shot hole borers and the diseases they carry, and Asian citrus psyllid and huanglongbing disease are serious invasive pests of concern. Do your part to help prevent their spread. If you go camping this summer, don't move firewood from your home to the campground. For backyard citrus growers, find out if you are in a quarantine zone for Asian citruspsyllid. You can make a difference. Read the posts above to find out...
When people think of parasites, often what comes to mind are blood-sucking insects like bed bugs, head lice, and fleas or other bodily invaders on or in humans and other animals. But plants can have parasites too. Most of us are familiar with mistletoe but there is another parasitic plant you may not have heard about: dodder.
There are several species of dodder native to California but they are not as problematic as a particularly invasive species, Japanese dodder, Cuscuta...

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.
What is an invasive species?
Invasive species are non-native plants, animals, or pathogens that can cause economic or environmental harm. These invading species can damage:
- Native plants and animals—especially those that are endangered
- Agriculture—both farming and ranching operations
- The...
May is Lyme Disease Awareness Month, giving us an opportunity to shine a spotlight on a serious illness transmitted by certain ticks.
Lyme disease is often associated with the northeastern and upper Midwestern areas of the United States. However, the disease has been found in some northern California counties, which means the risk of contracting the disease is possible in California.
Lyme disease can be transmitted to humans and pets through the bite of infected ticks. In California, the tick capable of transmitting Lyme disease is the western blacklegged...
California ground squirrels are common throughout much of California and may be found living near homes, structures, gardens, and landscapes where they can be a real nuisance. Ground squirrels' damaging habits can include:
- Eating vegetable seedlings and green grasses
- Damaging young shrubs, vines, and trees by gnawing on and girdling trunks
- Eating twigs and leaves
- Burrowing in lawns and landscapes and around tree roots
- Gnawing on plastic sprinkler heads and irrigation lines
Effective ground squirrel management methods vary during the year. In winter, manage populations before breeding seasons begins. Visit the UC IPM publication
