Ash trees have been decimated by the emerald ash borer, an Asian beetle that first struck in suburban Detroit in the early 1990s.

Also, not every new non-native species is equally threatening, so gauging the level of risk and responding accordingly is important to avoid misallocating limited resources on species of low ecological or economic concern. Bullfrogs compete with, and prey on, a wide range of native species, and may affect significantly native . The huge snakes can grow to 6 meters (20 feet) long.

Then there is the spotted lanternfly, native to East Asia, which is thought to have arrived in Pennsylvania in 2014 and is demolishing orchards and vineyards at a cost of millions of dollars a year. Some invasive species are tolerable if infestations can be contained and their impacts minimized. . For example, in Sumatra, rainforests on deep peatlands are being cleared, drained . In this study, by using high spatial resolution Planet imagery, an optimal approach was explored to improve the discrimination of S. chamaejasme from surrounding communities, integrated . 13112) in 1999 to to prevent the introduction of invasive species and provide for their control and to minimize the economic, ecological, and human health impacts that invasive species cause.

Official websites use .gov These fish feed on plankton, tiny organisms floating in the water. These include native forest insectsand pathogens. These plagues have also amplified climate change. Response plans could be developed in a format similar to the Columbia River Basin Interagency Invasive Species Response Plan: Zebra Mussels and Other Dreissenid Species. Small zebra mussels clog the cooling systems in boat engines, while larger ones have damaged water pipes at power plants throughout the Great Lakes region.Eradicating Invasive SpeciesOfficials have used a variety of methods to try to eradicate, or get rid of, invasive species. State statutes or agency administrative rules are in place to prohibit the unauthorized entry of undesirable invasive species. The Times is committed to publishing a diversity of letters to the editor. Stellera chamaejasme (Thymelaeaceae) is amongst the worst invasive species of the alpine grasslands on the Qinghai-Tibet Plateau; timely and effective monitoring is critical for its prevention and control.
