Facebook Beech leaf disease can kill mature trees in 6-10 years, young trees even more quickly and saplings in as little as two years. 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. Current research suggests that it affects the ability of beech trees to photosynthesize and is associated with the nematode, Litylenchus crenatae mccannii. Keeping an eye out for symptoms of BLD is also a good way to help with early detection and rapid response. However, beech trees are important economically, socially, and ecologically. SUNY Buffalo State This is an emerging disease of American and European beech that was first observed in Lake County, Ohio (Cleveland area) in 2012. Reduced bud and leaf production lead to loss of canopy cover. Ecosystem services, carbon sequestration, biodiversity maintenance, and aesthetic and recreational value that would be lost amounted to $225 million. Invasive Species → November 2019 . The darkened area is thicker and slightly raised compared to the rest of the leaf tissue. And recently discovered in southwestern New York is another disease affecting beech trees known as beech leaf disease (BLD). Scientific Name: Litylenchus crenatae mccannii Moving untreated firewood is one of the main ways invasive pests and diseases spread. Beech trees also provide important ecosystem services such as water filtration, carbon sequestration and biodiversity maintenance. Research is ongoing to develop control and eradication measures. It has since 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. Origin: Unknown. If you find yourself standing underneath a beech tree and think that you see symptoms of BLD, email NYSDEC Forest Health at [email protected] or reach out to Laura Bailey at Cornell Cooperative Extension of Yates County at 315-536-5123 or [email protected] (716) 878.4708, FIND US ON SOCIAL MEDIA In New York State where our predominant forest type is beech/birch/maple, beech is one of the most common forest species. Catskills: CRISP It is thought by some researchers that BLD is caused by this nematode or a very similar species. Instagram, Western New York PRISM 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. Beech trees are already under threat from beech bark disease (BBD). 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. BLD was first discovered in North America in Lake County, Ohio in 2012. Some cases have shown saplings being killed in as little as one year. 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. Long Island: LIISMA One such recent example is beech leaf disease (BLD). Adirondack Park Most mortality occurs in saplings within 2-5 years. Capital-Mohawk PRISM Whatever its cause, beech leaf disease is getting around. EPPO Alert List – Beech leaf disease - An emerging disease of beech of unknown etiology - Why. Finger Lakes PRISM Early detection and monitoring data can be used to determine rates of mortality and infection, as well as current distribution. 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. They provide great aesthetic value to both our forests and urban green spaces. In larger trees, disease progression is slower, beginning in the lower branches of the tree and moving upward. Beech trees are not only a component of the deciduous forest, they are commonly found in urban green spaces as well. NYS Department of Environmental Conservation, Forest Health, Forest Invasives Canada, Beech Leaf Disease, Great Lakes Center, SAMC 319 As the disease progresses the striping and thickening become heavier, there is reduced bud and leaf production, and leaves near the branch tips become deformed and shriveled. Beech are known as a foundational species, meaning that other organisms and overall functioning of the forest ecosystem depend upon these trees, and loss could therefore significantly impact other species. 1300 Elmwood Ave., Buffalo, NY 14222 Since it was detected, the disease has been observed in Ohio, Pennsylvania, New York, Connecticut, Rhode Island, Massachusetts, and Ontario, Canada. A new disease is killing American beech trees. Photo Credit: Jim Chatfield, OSU Extension, Common Name: Beech Leaf Disease Don’t move firewood more than 50 miles from its source. BLD was first discovered in North America in Lake County, Ohio in 2012. 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. Beech Leaf Disease - Beech leaf disease affects and kills both native and ornamental beech tree species.

A nematode was discovered by Ohio Department of Agriculture, and in 2017 a Japanese research group described this new species of nematode, Litylenchus crenatae. 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. Beech leaf disease is a newly discovered lethal disease of beech trees.The symptoms of the disease appear as a dark green, interveinal banding pattern on the lower canopy foliage, eventually spreading throughout the tree. 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. Connecticut officials last month announced detections in Greenwich, Stamford, and New Canaan, on New York City's doorstep. Where established, BLD mortality of sapling-sized trees can reach more than 90%. This eventually results in the death of the tree. Striping of the leaves is most apparent when viewing from below and looking up into the canopy. 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). St. Lawrence-Eastern Lake Ontario PRISM, © 2020 Western New York PRISM. Beech leaf disease is a relatively new threat and little is known about the biology of this disease. 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. Additionally, loss of canopy cover would alter the shade provided by beech and modify light levels on the forest floor. Beech Leaf Disease . Beech leaf disease can kill mature beech trees in 6-10 years and can kill younger trees even more quickly. The disease progression varies based on tree size. Early symptoms of BLD include striping or darkening of bands between the leaf veins and reduced leaf size. All rights reserved. Until more is known about BLD and how to control it, helping prevent its spread is a practice we can engage in. Hosts and Distribution .
