First, as an arid western state with a large fraction of its area in working landscapes such as rangelands and timberlands and with more than 40% of its land in public ownership (NRCM 2000), California has an unusually large stake in preventing the spread of invasive species that affect ecosystem provisioning services. Invasive species utilize a wide array of trait strategies to establish in novel ecosystems. The California Marine Invasive Species Program (MISP) is designed to reduce the risk of introducing nonindigenous species into their waters from ship 300 GT and above that are capable of carrying ballast water. While some species, like raccoons or American crows, are native to the region and ecosystem and simply prove nuisance, they are not invasive. Invasive species are a growing problem and, according to invasive expert and director of the University of Notre Dame’s Center for Aquatic Conservation David Lodge, one of the most “irreversible kinds of pollution”; it is now possible to reverse many chemical forms of pollution, but biological forms of pollution are extremely difficult if not impossible to reverse.

An invasive species is defined in Executive Order 13112 (USDI 1999) as a species that is nonnative (or alien) to an ecosystem and whose introduction causes or is likely to cause economic or environmental damage or harm to human health. The geographic diversity of California has led to broad evolution in native plants. From cane toads to kudzu, invasive species (sometimes called alien species) are those that aren't native to an ecosystem and that cause harm to native species, local economies or humans. The match between the invader and the existing native community may explain why exotic pest species are not uniformly noxious in all novel habitats. More invasive species will come to Canada, putting additional risk of native species extinction, warns Algoma University’s Canada Research Chair in Invasive Species. “They are a consequence of an increasingly connected world and the rising human population,” associate professor Pedro Antunes told Algoma’s board of governors during a meeting last Thursday. By educating the public about these species, their likely impacts, the pathways of introduction, and what to do if they are encountered, we aim to prevent introductions and intercept populations before they are able to establish, spread, and cause harm.
