Invasive plants and wildlife interact in numerous ways. In some cases, invasive plants replace native species that wildlife depend on for food or shelter. In other situations, wildlife use and spread invasive plants. These interactions are part of the factors considered in the California Invasive Plant Inventory. While it is difficult to quantify the impacts of a specific invasive plant on a particular animal, several success stories show how removing invasive plants can help wildlife

Wildlife and Invasive Plants Conference

To explore how weed workers and wildlife biologists can join together to protect ecological diversity, Cal-IPC and the Western Section of the The Wildlife Society sponsored a joint symposium in Monterey, January 30-31, 2007, entitled “Wildlife and Invasive Plants: Finding Common Ground to Protect Biodiversity.” Two hundred Cal-IPC and TWS members discussed interactions between wildlife and invasive plants and how our two professions can improve our own interactions. The meeting ended with a panel of experts who addressed the research gaps that need to be closed.
