There are many questions surrounding the need and effectiveness of invasive plant management, particularly the methods used. Fortunately, there have been many educational resources developed to explore these topics. Below are links to some of these educational materials.
The California Invasive Plant Council is a great place to start learning about invasive plants and their impacts on natural and human systems. (Start with the definitions and impacts pages.)
Invasive Plants are not just a state issue, as federal agencies take wildlife habitat and ecosystem health seriously.
UC has some great information about invasive weeds, and what management techniques are effective. The Weed Research and Information Center and the UC IPM website are great resources for invasive agricultural and urban weeds.
If left unchecked, invasive weeds can create monocultures reducing biodiversity. This picture shows a thick stand of dyers woad in Modoc County.
Grazing for Invasive Weeds
Grazing can be a useful tool within an integrated pest management program for noxious weeds. However, certain conditions need to be met, and considerations of the impact of grazing animals on desirable vegetation should be considered. Below are a couple of resources to learn more:
If grazed properly, cattle can help control certain invasive plants!
Herbicide Information Links
One area of particular concern is the toxicity of herbicide use to non-target species such as bees, birds, and people. Federal law requires testing of pesticides before registration, and California is unique because the state requires additional testing and regulations regarding the use of pesticides. Knowing the specifics of the tests and regulations regarding herbicide use can be beneficial when deciding if and when the use of a product is required.
One place to start is understanding the general definition of toxicity.
To understand toxicity in more detail, these publications from the University of Florida and Cornell do a good job explaining.
The National Pesticide Information Center has a lot of information about how pesticides interact with soil, water, and other aspects of the environment. Their fact sheets for individual pesticides are a good way to get more information about specific products.

Understanding the regulation involved with pesticides on a State and Federal level can be important to understand how and why they are used. The EPA regulates pesticides on a federal level, where California has it’s own EPA and a branch specifically devoted to registering and regulating pesticides. These organizations use scientific data to determine what and how pesticides can be used on the landscape without causing harm to the environment. Below are a couple of resources with more information about the studies and processes which are completed before pesticides are registered for use:
