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...
It's National Invasive Species Week (February 27-March 3), which may prompt the question, “what exactly is an invasive species?” A truly invasive species is a non-native plant, animal or pathogen that causes or may cause economic problems, or threaten the environment or human health.
Why should this matter to you? Every 60 days, our state gains a new and potentially damaging invasive species. Because the things you do can directly impact the environment and economy of California, here are the top 10 ways:
- Learn about the invasive species that live in your region. Check with your county agricultural extension...

The pathogen, Phytophthora tentaculata, poses a risk of disease in wildlands, gardens and landscapes that use susceptible California native and non-native plants. Once introduced in these areas, the pathogen can generate disease for years to come, potentially causing lasting environmental and economic...

Did you know that every 60 days, California gains a new and potentially damaging invasive species? Once established, invasive species are extremely difficult to eradicate and can cause not only ecological disruption, but economic problems as well.
This week (February 21-27) is National Invasive Species Awareness Week. The goal of the week is to raise awareness and identify solutions to invasive species.
What is an invasive species? The term “invasive” is often used to describe something that appears to be taking over a garden or landscape. However, according to the National Invasive Species Council, a true invasive species is...
