  • Rhode Island DEM Asks Public to be Aware of Beech Leaf Disease

    • Jul 13, 2020
    • Rhode Island Department of Environmental Management.

    • The Department of Environmental Management (DEM) is asking Rhode Islanders to monitor their beech trees for signs of leaf damage from Beach Leaf Disease (BLD). Early symptoms of BLD include dark striping on the tree's leaves parallel to the leaf veins and are best seen by looking upward into the backlit canopy. Drastic leaf loss occurs for heavily symptomatic leaves during the growing season and may appear as early as June, while asymptomatic and mildly symptomatic leaves show no or minimal leaf loss. BLD was detected in the Ashaway area of Hopkinton, Rhode Island, in 2020 and in coastal Massachusetts. Before these findings, the disease was only known to be in Ohio, Pennsylvania, New York, and Connecticut.

      Because of the seemingly random nature of disease in Rhode Island, DEM encourages homeowners and forest landowners to monitor their beech trees and report any suspected cases of BLD on DEM's Invasive Species Sighting Report webpage. Although BLD is relatively new in the U.S. and information is limited, links to additional information about the disease and photos are posted on the Division of Forest Environment's Current Threats page. If people have further questions, they should contact a licensed arborist or email Nancy Stairs, forestry program supervisor in DEM's Division of Forest Environment, via Nancy.Stairs@dem.ri.gov.

  • Changes Proposed to Texas Exotic Aquatic Species Regulations

    • Aug 28, 2020
    • Texas Parks and Wildlife Department.

    • The Texas Parks and Wildlife Department is proposing changes to regulations regarding harmful or potentially harmful fish, shellfish and aquatic plants. The proposed changes significantly reorganize the existing rules to enhance accessibility, meet the changing needs of the regulated community, and address current and potential future threats posed by these exotic species. The proposed rules will be published in the Texas Register no later than Friday, Oct. 2. At that time, comments on the changes can be provided on the TPWD public comment page until Monday, Nov. 9. The TPW Commission will take public comment on the proposed changes at their meeting on Tuesday, Nov. 10 in Austin. Comments on the proposed changes also can be submitted to Ken Kurzawski at (512) 389-4591, email: ken.kurzawski@tpwd.texas.gov.

  • ARS Scientists Seek Answers from Spotted Lanternfly Dispersal

    • Sep 11, 2020
    • USDA. Agricultural Research Service.

    • The Spotted Lanternfly is an invasive species that destroy fruit crops, trees and plants by hopping from plant to plant, crop to crop, and tree to tree. Although native to regions in China, India, and Vietnam, it was first detected in Berks County, Pennsylvania in 2014. Since then, Pennsylvania vineyards have seen considerable damage in high infestation areas and the Mid-Atlantic states of Delaware, Maryland, New Jersey, Virginia and West Virginia have also suffered from its presence. Insecticides are effective at killing the insect on grapevines, but they are expensive and of limited use because of constant re-infestation from the Spotted Lanternfly dispersing from wild hosts to surrounding vineyards. So, U.S. Department of Agriculture Scientists Dr. Tracy Leskey and Dr. Laura Nixon of the Appalachian Fruit Research Station in Kearneysville, West Virginia, initiated research on the invasive pest to see if they could develop sustainable pest management strategies and use the insect's dispersal patterns for other prolific specialty crop pests.

  • NYS DEC Encourages Delaware River Anglers to Report Invasive Snakehead Sightings

    • Aug 26, 2020
    • New York State Department of Environmental Conservation.

    • New York State Department of Environmental Conservation (DEC) Commissioner Basil Seggos today encouraged anglers in the Delaware River to be on the lookout for northern snakehead, an invasive fish native to Southeast Asia. A northern snakehead was recently caught in the Callicoon area of the Delaware River. Given the right environmental conditions, this invasive species can prey on and compete with other fish, upsetting the natural balance of local ecosystems. "Northern snakeheads are listed federally as injurious wildlife, and New York State law prohibits their live possession," Commissioner Seggos said. "Any snakehead caught should be killed immediately and not released back into the water." In the event an angler catches a northern snakehead, DEC advises anglers to report the catch to the regional NYS DEC fisheries office, DEC's Invasive Species Bureau at isinfo@dec.ny.gov or (518) 402-9425, or submit a report through iMapinvasives.

  • USDA and Wyoming Sign Shared Stewardship Agreement to Improve Forests and Grasslands

    • Aug 25, 2020
    • United States Department of Agriculture.

    • U.S. Department of Agriculture (USDA) Secretary Sonny Perdue joined Wyoming Governor Mark Gordon in a virtual ceremony to sign a Shared Stewardship Agreement between USDA’s Forest Service and the State of Wyoming [PDF, 2.1 MB]. The Shared Stewardship Agreement establishes a framework for federal and state agencies to promote active forest management, improve collaboration, and respond to ecological challenges and natural resource concerns in Wyoming. Under the agreement, the State of Wyoming and USDA will work together on forest and grassland restoration across all land ownerships, with a focus on protecting at-risk communities and watersheds from wildfire. The USDA Forest Service initiative for cross-boundary land management is described in the 2018 document Toward Shared Stewardship Across Landscapes: An Outcome-Based Investment Strategy [PDF, 14 MB]. This strategy addresses the increasing challenges faced by federal, state, and private managers of forests and rangeland, including catastrophic wildfires, invasive species, degraded watersheds, and insects and disease.

    • Urges Public to Look For Invasive Asian Longhorned Beetle and Not Move Firewood

      August is the peak time of year to spot the Asian longhorned beetle (ALB) as adults emerge from trees. That’s why the U.S. Department of Agriculture (USDA) is declaring August as ‘Tree Check Month.’ Checking trees for the beetle and the damage it causes is one way residents can protect their own trees and help USDA’s efforts to eliminate this beetle from the United States.

  • The Electonic-Nose, an Early Detection Tool for Emerald Ash Borer Larvae

    • Electronic noses are sensitive to a vast suite of volatile organic compounds that every living organism emits. A new USDA Forest Service study shows that e-noses can detect emerald ash borer (Agrilus planipennis) larvae lurking under the bark – an early, noninvasive detection method.

  • Asian Longhorned Tick Found in Kentucky

    • Jul 21, 2020
    • University of Kentucky. College of Agriculture, Food, and Environment.

    • The Asian longhorned tick, which preys on a variety of hosts including humans and wild and domestic animals, has been found in Kentucky. This new tick is known to attack animals in large numbers and will be a concern to livestock producers, wildlife enthusiasts and pet owners. The tick has been found in small numbers on elk in Martin County and black bear in Floyd County. It was found in large numbers on a bull in Metcalfe County in the south-central part of the state. Individuals who find a usually large number of ticks on their pet or livestock should contact their local veterinarian. Those who find single ticks they think might be an Asian longhorned tick should work with their county extension agent for agriculture and natural resources to submit the sample to UK entomologists for positive identification.
