While many non-native plants are extremely beneficial to society, invasive plants spread rapidly and cause, or are likely to cause, harm to native ecosystems. The cost and difficulty of managing invasive non-native species increases substantially once a species has established self-sustaining populations. An invasive species is an organism that is not indigenous, or native, to a particular area. They also need to know what level of investment is appropriate, and which techniques are most appropriate for each respective situation. These rain forests once stretched from southern Oregon to southeast Alaska, but little remains outside of protected areas.

The Forest Service works with partners at all levels to respond to and manage invasive species, as well as other native pests and diseases, that threaten the lands and waters of the United States. Controlling established invasive species often requires a long-term commitment. Once introduced, natural pathways may help to spread invasive species, especially plants whose seeds or parts are easily dispersed by wind, water, and wildlife. Temperate forests, boreal forests and woodlands have also experienced multiple pressures, leading to an at-risk . (Prohibited and Controlled Fish, Mollusks, and Crustaceans). Invasive non-native species are highly adaptable and competitive, using space, water, and sunlight of disturbed ground. Keystone species fall into several broad categories. Not all non-native species are invasive. An invasive species is both non-native to the ecosystem in which it is found and capable of causing environmental, economic, or human harm because of its ability to spread rapidly and compete with native species. There are two species in North American temperate forests, black bears and brown or grizzly bears. The Pacific Temperate Rainforest in British Columbia is home to endangered species such as the Roosevelt elk, marbled murrelet, and the northern goshawk.
