Located across approximately 39 states, feral hogs cause an estimated $1.5 billion annually in agricultural and ecological damage. The Arkansas Feral Hog Eradication Task Force is a group of agencies dedicated to eradicating feral hogs from the state. Accurately measuring the Arkansas feral hog population is part of that process. Sightings can be reported at the Arkansas Feral Hog Sighting Report Form.

The collection of digital images is provided as a service to Arkansas agriculture. These images represent symptoms of both pathological (infectious) and non-pathological (physiological/environmental) disorders of agronomic row crops and horticultural crops that grow in Arkansas. These photos are useful as an identification tool to growers of the crops listed.

Feral swine are an invasive species which cause extensive damage to crops, property, and the environment. They are also known to carry over 30 diseases and 37 parasites that can be transmitted to livestock, people, pets, and wildlife. When feral swine are sighted in North Dakota, the State Board of Animal Health should be notified immediately. Attempts will be made to identify whether the swine are truly feral or if they are escaped domestic swine which are private property. Individuals who encounter feral swine should not destroy them unless they encounter feral swine on their own property and there is a threat of harm or destruction of property. As soon as possible following destruction of the animal, but always within 24 hours, the individual must notify the State Board of Animal Health (BoAH) at 701-328-2655.

Firewood is widely recognized as a major source of non-native forest insect and disease infestations. A rule governing the importation of untreated firewood into Vermont went into effect on May 1, 2016. Visitors to Vermont State Parks, Vermont State Forests, and the Green Mountain National Forest may only bring firewood originating from Vermont or that is heat treated and in its original, labeled package. To help slow the spread of emerald ash borer within Vermont, ash firewood that has not been heat treated should not be moved outside of the Emerald Ash Borer Infested Area in Vermont.

Vermont Invasives.

An emerald ash borer (EAB) beetle was detected in a tree located in Londonderry, VT. The mapped area in Vermont (PDF | 1.25 MB) to which "Slow-the-Spread" recommendations apply now covers:

  • All of Londonderry, Windham, and Landgrove;
  • Most of Jamaica, Winhall, Peru, Weston, Andover and Grafton; and
  • Extends into Chester, Townshend, Stratton, Athens, Mount Tabor, and Wardsboro.

October means that non-flight season Recommendations to Slow the Spread of Emerald Ash Borer are now in effect when moving ash from the infested area. With the heating season underway, and firewood deliveries actively occurring, it’s important to remember that untreated ash firewood should never move out of infested areas. Be sure that your purchase or transportation of both log length and split firewood will not unnecessarily spread EAB. There’s a lot of spread to slow: While the infested area map shows that high-risk areas for EAB include many towns, visibly infested trees still remain rare in Vermont. You can help by following the "Slow-the-Spread" recommendations.

Quagga mussel larvae, or veligers, were first confirmed in Lake Powell in late 2012 after routine water monitoring tests discovered mussel DNA in water samples taken from the vicinity of Antelope Point and the Glen Canyon Dam. As of early 2016, thousands of adult quagga mussels have been found in Lake Powell, attached to canyon walls, the Glen Canyon Dam, boats, and other underwater structures, especially in the southern portions of the lake. It is crucial to keep the mussels from moving from Lake Powell to other lakes and rivers. Utah and Arizona state laws require you to clean, drain, and dry your boat when leaving Lake Powell using self-decontamination procedures.

Aquatic invasive species (AIS) personnel from the Utah Department of Natural Resources (DNR) have stopped more than 120 mussel-infested boats this year, most of which had visited Lake Powell, from launching at other Utah waterbodies. So far in 2018, more than 100 mussel-infested boats have been quarantined, a significant increase compared to recent years. "The quagga situation at Lake Powell has worsened. If you boat at Lake Powell it's very likely your boat has quagga mussels on it," said AIS Program Coordinator Nathan Owens. "With more mussels in the lake and lower water levels more boaters have mussels attached to their vessels than in past years. Our techs are regularly finding them on and in boats that have only been in Lake Powell for a day or two — something we haven't experienced in the past." Boaters that visit another lake or reservoir after visiting Lake Powell will have their boat inspected again. If mussels are found the boat will be decontaminated and quarantined, if necessary.

It is crucial to keep the mussels from moving from Lake Powell to other lakes and rivers. Utah and Arizona state laws require you to clean, drain, and dry your boat when leaving Lake Powell using self-decontamination procedures. Additional steps are required if you launch on other waters without a significant drying period or if you are on Lake Powell for more than 5 days.

A North Dakota Emerald Ash Borer First Detector Program has been cooperatively developed by the North Dakota Forest Service, North Dakota State University, North Dakota Department of Agriculture, National Plant Diagnostic Network and the USDA APHIS Plant Protection and Quarantine to train citizens of North Dakota to correctly identify symptoms and signs of EAB. If you are interested in becoming an EAB first detector in North Dakota, contact Aaron.D.Bergdahl(at)ndsu.edu. Also available is the 2014 Emerald Ash Borer First Detector Manual (PDF | 33.7 MB).
