Most plants sold at California nurseries are not in the category of invasive plants and will not invade or harm wildlands. Some plants however are vigorous and aggressive plants which can be invasive in the right environment. Invasive plants harm the environment by displacing native plants and wildlife, may increase fire danger, consume water, reduce recreational opportunities, reduce or destroy production from ranch and forest lands, and take funding from other programs to fight their establishment and spread. Please select plants for your area that are not invasive.

Natural areas are damaged by invasive plants. If you live in or near a natural area, invasive species should not be planted. SelecTree provides a California Native filter to aid in your search.

SelecTree's invasive plant information is taken from Cal-IPC California Invasive Plant Council on August 2006 and is displayed in the tree notes or memo section of the tree report.

Invasive plants are rated as High, Moderate and Limited.

• High - species have severe ecological impacts on physical processes, plant and animal communities, and vegetation structure.
• Moderate - species have substantial and apparent but generally not severe ecological impacts on physical processes, plant and animal communities, and vegetation structure.
• Limited - species are invasive but their ecological impacts are minor on a statewide level or there was not enough information to justify a higher score.
