The states of Oregon, Washington, and Idaho are urging people to report any feral pig sighting by calling a toll-free, public hotline, the Swine Line: 1-888-268-9219. The states use hotline information to quickly respond to a feral swine detection, helping to eradicate and curb the spread of the invasive species.

Oregon Invasive Species Council.

Think you've found an invader? Oregon needs your help. Early detection is critical to keep Oregon protected from new invasives. If we can detect new outbreaks early and act quickly to control them, we save Oregon's natural resources and prevent costly eradication efforts. By the time an invader is easily noticeable and begins to cause damage, it is often too late.

Palmer amaranth (Amaranthus palmeri) and houndstongue (Cynoglossum officinale L.) have been added to the state noxious weed list. Palmer amaranth is an aggressive pigweed species similar in appearance to waterhemp and was first found in the state last year. It has now been found in five counties. Houndstongue, which does not spread aggressively like Palmer amaranth, has been found in North Dakota since at least 1911 but infestations have tripled since 2008. It is now found in at least 25 counties. The public is urged to work with local weed officers, extension agents and other experts to identify and report suspect plants. More information on these and other noxious and invasive weeds is available at https://www.nd.gov/ndda/plant-industries/noxious-weeds.
