This eventually results in the death of the tree. Finger Lakes PRISM Forest Health Aerial Survey Program - Each year DEC and the NYS Police Aviation Unit conduct a two-month aerial survey of the State's forests to detect possible threats by insects, diseases, human activity and major weather events. Hosts and Distribution . Until more is known about BLD and how to control it, helping prevent its spread is a practice we can engage in. An affliction generically referred to as beech leaf disease (BLD) has been contributing to the decline and mortality of American beech across Ohio, Pennsylvania, New York, Connecticut, and Ontario. Beech leaf disease is a relatively new threat and little is known about the biology of this disease. This could cause change to species composition, forest structure, and expose areas to potential introduction of invasive species. Beech trees also provide important ecosystem services such as water filtration, carbon sequestration and biodiversity maintenance. Scientific Name: Litylenchus crenatae mccannii Keeping an eye out for symptoms of BLD is also a good way to help with early detection and rapid response. The disease also appears to spread faster between beech trees that are growing in clone clusters, as it is able to spread through their connected root systems. Photo Credit: Jim Chatfield, OSU Extension, Common Name: Beech Leaf Disease Beech leaf disease can be found on our native American beech (Fagus grandifolia), as well as on ornamental varieties including European beech (Fagus sylvatica) and Oriental beech (Fagus orientalis). © Gannett Co., Inc. 2020. Lower Hudson PRISM Beech leaf disease is a relatively new threat and little is known about the biology of this disease. We appreciate the shade they provide on a hot, sunny day and recognize them by their smooth gray trunks that have the appearance of giant elephant legs, and in which you often find the initials of lovers enclosed in a heart. More research to better understand how BLD is caused and how it spreads is ongoing, but it behaves much like an invasive forest pathogen, spreading rapidly and causing significant ecological and economic damage. (716) 878.4708, FIND US ON SOCIAL MEDIA American beech is one of the most common tree species in New York State, and birds, black bears and other wildlife rely heavily on beech nuts for food. Spread of similar invasive species is prevented by restricting the movement of firewood and wood products, as well as by conducting early detection surveys. However, beech trees are important economically, socially, and ecologically. And recently discovered in southwestern New York is another disease affecting beech trees known as beech leaf disease (BLD). called 'Beech leaf disease' (BLD) has increasingly been observed in forest areas in Eastern USA and Canada (EPPO RS 2018/178, 2020/082) and is raising serious concerns among foresters and local communities in affected areas. In larger trees, disease progression is slower, beginning in the lower branches of the tree and moving upward. A nematode was discovered by Ohio Department of Agriculture, and in 2017 a Japanese research group described this new species of nematode, Litylenchus crenatae. Beech trees provide wildlife with food and habitat, such as beech nuts for turkey and black bears, dens for small mammals, and cavity nests for woodpeckers and songbirds. Heavily infected trees may also have reduced leaf and bud production, and a single tree can contain both heavily infected and unaffected branches. Connecticut officials last month announced detections in Greenwich, Stamford, and New Canaan, on New York City's doorstep. Capital-Mohawk PRISM They provide great aesthetic value to both our forests and urban green spaces. And recently discovered in southwestern New York is another disease affecting beech trees known as beech leaf disease (BLD). SUNY Buffalo State St. Lawrence-Eastern Lake Ontario PRISM, © 2020 Western New York PRISM. Striping of the leaves is most apparent when viewing from below and looking up into the canopy. Beech Leaf Disease has spread across Ohio, into Northwestern Pennsylvania, Southwestern New York and Long Island, Southwestern Connecticut, as well as the northern shore of Lake Erie in Ontario, Canada. Reduced bud and leaf production lead to loss of canopy cover. The presence of beech bark disease (BBD), caused by a combination of bark and vascular tissue damage by the beech scale insect and the subsequent infection by several fungal species, which has been affecting American beech trees in New York State for decades, leads to root suckering and basal sprouting when an infected tree begins to decline.

Whatever its cause, beech leaf disease is getting around. In addition to the social losses from loss of beech trees, researchers in Ohio used a model to predict economic losses if half of the beech trees in the state were lost. Studies of other disease agents that could cause or have involvement in BLD are also being conducted. Ecosystem services, carbon sequestration, biodiversity maintenance, and aesthetic and recreational value that would be lost amounted to $225 million. BLD was first discovered in North America in Lake County, Ohio in 2012. Beech trees are already under threat from beech bark disease (BBD). Some cases have shown saplings being killed in as little as one year. Beech leaf disease was first spotted in northeast Ohio in 2012 and, as of January 2019, has been spotted in 10 Ohio counties, eight Pennsylvania counties, one county in New York, and five counties in Ontario, Canada. Although BLD is unlikely to cause extinction of American beech trees, it could cause functional extinction of the species, meaning the reduced population will no longer play a significant role in ecosystem functioning. Instagram, Western New York PRISM Pathways: More research must be conducted to determine how beech leaf disease spreads and to develop effective prevention protocols. Origin: Unknown. In New York State where our predominant forest type is beech/birch/maple, beech is one of the most common forest species. Beech leaf disease is characterized by leaves that are striped between the leaf veins, curled along the margins or that have developed a leathery texture. Loss of beech leaf litter on the forest floor could lead to changes in nutrient cycling, soil moisture, and reduce nesting material, hiding places and protected spots for small mammals, reptiles, amphibians, and insects. Moving untreated firewood is one of the main ways invasive pests and diseases spread. BLD was first discovered in North America in Lake County, Ohio in 2012. EPPO Alert List – Beech leaf disease - An emerging disease of beech of unknown etiology - Why. Beech leaf disease can kill mature trees in 6-10 years, young trees even more quickly and saplings in as little as two years. Beech Leaf Disease - Beech leaf disease affects and kills both native and ornamental beech tree species. Current research suggests that it affects the ability of beech trees to photosynthesize and is associated with the nematode, Litylenchus crenatae mccannii.
