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...

Wild pigs can be a major nuisance for farmers, ranchers, and others who live in more rural areas or near wildlands. They will invade fields and eat crops, disturb plantings by rooting through the soil, and defecate in fields leaving behind bacteria and parasites.

Spanish missionaries brought domestic pigs to California in 1769 for consumption, but after being released for foraging and not recaptured, they escaped domestication and became feral (wild).

Domestic pigs are a familiar farm animal, but have you heard about wild pigs? These animals are destructive pests with voracious appetites and eat a wide variety of plants and animals. It's estimated wild pigs cause $1.5 billion in economic damage to agriculture and the environment in California every year!
Where Did They Come From?
Domestic pigs were released in California in 1769 to be raised for consumption. Some of these pigs were not recaptured and became feral. In the 1920's, Russian wild boars were brought to California for sport hunting. Since both types of pigs belong to the same species, they interbred. Their descendants are called wild pigs.
Why are They a Problem?
