Birch trees are a very lovely addition to your yard, but they suffer from one of the most destructive of all pest infestations: the bronze birch borer. This pest causes life-threatening damage to birch trees across the nation. Understanding these creatures and how to treat them can help clean them out of your yard forever.
Life Cycle
The life cycle of the bronze birch borer is incredibly destructive because every step of it somehow involves damaging birch trees. Adult borers eat the leaves of the birch tree to prepare themselves for egg laying. When they're ready, they will lay their eggs in cracks in the bark. And once the eggs hatch, the larva burrows into the surface of the tree.
Here's where the most damage is done: the bronze birch

Intriguingly, they tend to be more attracted to birch's with white bark, such as paper birch and gray birch: as a result, they more rarely attack river birch, sweet birch, or yellow birch.
However, once they infest a tree they will continue to feed on it for years, causing severe damage to nutrient transport systems, which can cause massive leaf die offs, dead roots, and the death of the tree itself.
Range of Infestation
Wherever there are birch trees, the bronze birch borer can be found. However, they are more prominent in northern states and across the Canadian border. For example, they have been found as far east as Newfoundland and Maine and as far west as British Columbia and Idaho.
Treatments
Eliminating the bronze birch borer from your trees and restoring them to their natural health requires multiple treatment methods. First of all, you need to ensure the health of your tree by watering them regularly: one slow watering every few weeks should be enough. Next, you need to spread at least three-inches of wood chips around the base of the tree to hold in moisture. Most importantly: do not fertilize your trees when they are infested with the bronze birch borer: the extra growths can actually attract more birch borers to your
The red necked cane borer, Agrilus ruficollis (F.), is a buprestid beetle that infests wild and cultivated blackberries and raspberries in the eastern states from Canada to the Gulf of Mexico. Adults are about 6-7 mm (1/4 inch) long, with an iridescent coppery pronotum. A related species, Agrilus rubicola, may occur concurrently. This species is uniform in color, ranging from copper-colored to iridescent green. On galled plants, there is less live vegetative growth and more dead wood. There is often reduced berry size and number, as well as vegetative growth with increasing number of galls per plant. Affected canes may not produce fruit. Canes weakened by galls are more subject to winter injury.
Proper removal and disposal of the dead Ash Trees can help with eliminating the spread of the disease to other areas of the city and replanting a variety of trees in the affected Ash Tree areas can help with biodiversity of tree species in the city to prevent another spread from destroying many of our trees. With many different tree species, if there is another beetle or borer outbreak that affects a certain species of tree, It would not be as devastating to the entire tree population because it would only affect a select few trees throughout the
They are critically endangered with their population decreasing due to bushfires and logging. Ironically, the reason for logging is to prevent fires but if they let the trees live, the fires could ultimately burn out all of their habitat and more. They live in hollows of old trees that could take up to 150 years to form.
Today I will be explaining the Boreal Forest Taiga. So let’s have fun and get into this information and learning. If you don’t know what a Boreal Forest Taiga is you are going to learn today. The Boreal Forest Taiga is a forest that has extremely cold winters and warm summers. Also all trees in this area are evergreen trees and has shallow roots. The Forest contains animals that have thick skins and can stand extreme whether. This forest has the same characteristics as some other forest. This place mainly contains real evergreen trees we use as Christmas trees. Trees here can grow up to 40-80 feet tall. Winters here are very cold and the temperature can get up -50 degrees fahrenheit.
Emerald Ash Borer (EAB) most likely came to the United States through solid wood shipments from Asia, and has established its habitat in 25 states - including Georgia - and two Canadian provinces. The female lays eggs and the cream-colored larvae chew tunnels through the wood. The adults are shiny green beetles about a half inch in length and burrow through the wood. Symptoms of EAB infestation in a tree include vertical
The trees do a lot of evapotranspiration, so if the borer destroyed them, the watershed levels would increase. This increase would negatively affect plant diversity because invasive species and grasses would start to become present. In urban areas, there is usually more diversity, so the absence of black ash would not affect the habitat that significantly. Also, if a tree dies in an urban environment, another one can be planted. On the other hand, in a forested wetland, if black ash trees start dying they would be very hard to replace and replenish. Slesak et al., 2014 state that if evapotranspiration is affected, a shift in the vegetation would occur and favor herbaceous vegetation rather than trees. There are various methods used to manage the spread of EAB to black ash forested wetlands. Mercader et al., 2011 bring up one method, which consists of removing ash trees to reduce available host phloem resource. Basically, foresters cut down trees that can host EAB, attempting to eliminate their presence. A different method, brought up by BenDor et al., 2006, consists of implementing firewood
The question arose about the cost benefits of treating the tree versus cutting them down. It cost approximately $43.00 to treat one tree versus the $400.00 to cut the tree down, grind the stump away, and plant a new tree in its place. Even though many Ash trees have been saved by this treatment, it was too late for some. So far 10,500 Ash trees have been cut down in the city of Fort Wayne because they were attacked by the Ash Borer. This year another 2,447 will be cut down also. Mudrack Tree Experts have
The emerald ash borer, Agrilus planipennis, is a beetle that was first discovered in 2002 in the US near the Detroit area and southeastern portions of Michigan. This beetle is believed to have originated in Asia. The theory is that they arrived in the states in packing material made of wood on cargo ships traveling on the St. Lawrence River, which then leads into the Great Lakes. Since 2002, this beetle has made its way into parts of Canada and now in at least eighteen states in the US (Emerald, n.d.). They are causing major destruction of Ash trees in all of these areas, and Vermont is starting to take precautions to be prepared if and when these beetles show up in The Green Mountain
The Eastern Hemlock is being attacked by the Hemlock Wooly Adelgid. This invasive aphid-like insect kills Hemlock by feeding on their starch reserves and injecting a toxin into them that causes their needles to drop more quickly. According to the article “Rehabilitation Guidelines for Hemlock Stands,” “Adelgids cause damage by depleting the Hemlock’s starch reserves.” When the starch reserves are depleted, the tree doesn't have enough energy to grow. The Hemlock Wooly Adelgid’s toxin causes needles to fall off the tree faster, as shown in the article “Forest Health Fact Sheet”. With less needles to perform photosynthesis in and not enough energy reserves to grow new ones, the tree is unable to store enough energy to live well through the dark winters, and it dies within a few years.
Emerald Ash Borers has killed millions of ash tree and put billions more at risk. Emerald Ash Borers originated in Asia and eastern Russia was first discovered in Canada in 2002. It is now widespread in Quebec and Ontario areas. Emerald Ash Borers can be spread to various parts of Canada and USA through infested firewood trading. Therefore the government of Canada has decided to restrict infested areas. Emerald Ash Borer arrived to Canada through trading forestry products. If we had been more careful, Emerald Ash Borers would have never entered Canada. Therefore our interaction in cutting down trees to trade and trading with others has an important effect on the welfare of our forests. The interaction of receiving wood from outside our country
Emerald ash borer probably arrived in the United States on solid wood packing material carried in cargo ships or airplanes originating in its native Asia. Emerald ash borer is also established in Windsor, Ontario, was found in Ohio in 2003, northern Indiana in 2004, northern Illinois and Maryland in 2006, western Pennsylvania and West Virginia in 2007, Wisconsin, Missouri and Virginia in the summer of 2008, Minnesota, New York, Kentucky in the spring of 2009, Iowa in the spring of 2010, Tennessee in the summer of 2010, Connecticut, Kansas, and Massachusetts in the summer of 2012, New Hampshire in the spring of 2013, North Carolina and Georgia in the summer of 2013, Colorado in the fall of 2013, New Jersey in the spring of 2014, Arkansas in the summer of 2014, and Louisiana in the winter of
Higher temperatures not only decreased winter severities, but produced drought conditions throughout Colorado in the late 1990s, eventually becoming severe by 2000 (“Frequently Asked Questions”). This lack of moisture in the soil and in Colorado’s precious pine forests put the trees under extreme stress, forcing them to compete for water. The stress of this competition for moisture makes it increasingly difficult for trees to fend off the Mountain Pine Beetle during an attack, making them a vulnerable target (Funk and Saunders). Pine trees are unable to fight off infesting Mountain Pine Beetles until they have burrowed into the living cells of the phloem. According to Hillary Rosner of National Geographic, once the beetle has reached the phloem, the tree
The fungus develops in the root collar area of the tree. It travels underneath the bark by forming distinctive white mycelial fans and rhizomorphs. White mycelia fans are mats of irregular fan shaped mycelium. It grows between the wood and bark and girdles it, causing the separation between the two. The mycelia releases biopolymer degrading enzymes that allows the fungi to penetrate the bark and is used to break down the wood. The secretion of enzymes and with the separation between the wood and bark, causes the death of the tree. After decomposing, the mycelium fans leaves an impression in the resign saturated inner side of the bark.
The Canadian Shield has many forests, within those forests are a lot of trees. Mostly trees grow in the Shield. The types of trees that are found are birch, aspen, hemlock, pine and balsan. The trees listed are found in the southern parts of the Shield. There is also tamarack, black spruce and white spruce trees are in the forests of the Shield, a lot of the forests in the shield have a mix of many trees.
