It’s not the latest comic book super villain that we’re worried about, here in Northwest Ohio. No, it’s a little green beetle that, since 2003, has been munching its way through our neighborhoods and Metroparks. The Emerald Ash Borer (EAB) feasts on our Ash trees, leaving us little choice but to spray a bright red stripe or “X” on the trunks of the mortally wounded flora.
The stark tattoo of removal.
“The irony of thousands of ash trees being cut down this Arbor Day marks a tragic chapter in the history of Metroparks,” Jack Gallon, President of the Board of Park Commissions wrote in a letter to TCP, “One way we can channel our disappointment in a positive way is to urge our federal lawmakers to close the door to exotic species that arrive on American shores at the rate of one every eight months. The cost of prevention is small compared to the cost to our native plants and animals. Pearson Metropark is proof of what we stand to lose.”
The EAB, an exotic Asian pest, was discovered in North America about five years ago, and was spotted in the Detroit area during the summer of 2002. Since then, it has apparently migrated south, infiltrating Lucas County as well as Wood, Defiance, Franklin, Fulton, Hancock, Henry and Williams Counties. It isn’t the adult beetles that cause the most damage, it’s their larvae. They burrow and nibble their way through the inner bark of Ash trees, affecting the trees’ ability to move the needed nutrients and all important water throughout. What we’re left with are a bunch of trees that are cracked where the burrows have forced the bark to split.
And then, we’re left with no choice. It’s just too late. Get out the can of day-glow red because once the tree is infested, there is no saving it. “Perhaps the biggest misconception being perpetuated is that the ash trees at Peason can somehow be saved. Sadly, the evidence refutes that,” claims Scott Carpenter, Communications Manager for the Metroparks of the Toledo Area. “Based on what has happened in Michigan, it is clear that it is too late to protect the trees at Pearson. Once an emerald ash borer infests an area, it is 100 percent fatal to ash trees.”
Five species of Ash – 20-30,000 trees – are slated for removal from the Pearson and Oak Openings Metroparks, with Pearson closed until June 30, 2005 and having the priority date of May 15, 2005.

ImageText BoxImageOne of the biggest threats to the environment of Ontario is the Gypsy Moth (Lymantria dispar dispar). The species itself is native to Europe and Asia. How this affects us is by weakening trees across Ontario and North America. The first time the gypsy moth was found in Ontario was 1969. The gypsy moth can be found in southern Canada (Ontario), New Brunswick, Nova Scotia and British Columbia. It is known to weaken trees and the caterpillar form live in trees and during most outbreaks its caterpillar feces would fall from the trees to the ground or even on top of humans. The average Gypsy Caterpillar can grow 5-6 centimeters long. With five pairs of blue spots and six pairs of bright red dots on their back. The female moth are white and can fly on the other hand, the male moth are brown and can also fly. The female have a 5cm wing span but male have a 2.5cm wing span. The gypsy moth usually lives in open forests and other forests and take up at least 20% of the space. The Gypsy moth are about 4cm long, tan coloured and can be located on tree trunks, furniture, and buildings. (OFAH Invading Species Awareness Program, 2012)
The population of bats in the United States is facing a serious threat of extinction due to the outbreak of a deadly fungus called Deomyces destructans. The fungus is nicknamed White-Nose Syndrome, after the white fungus that typically appears on the infected bats noses and wings. Other signs and symptoms of White Nose Syndrome are white fungus on the ears and tail as well, bats flying during the day in the middle of winter, bats clustered near the entrance to a hibernacle or cave, and general abnormal behavior for a hibernating bat. Scientifically the fungus has been identified as, Deomyces destructans. The fungus itself causes damage to their connective tissues, muscles, and skin. It also can disrupt many of their physiological processes. Typically during a hibernation period bats will wake up on average every 10 to 20 days. An infected bat on the other hand will wake up every 3 to four days which causes them to burn up their fat stores twice as fast. When they wake up they are both dehydrated and hungry, around 90% of the bats actually die from starvation due to a lack of insects for food in the winter season. WNS is transmitted from bat to bat and that is why any contact between an infected bat from one cave population with a non-infected bat from another population has serious consequences.

The effects of deforestation around my home and throughout my state are becoming more evident every day. When a deer or other wild game loses its home, they move into cities, urban areas, and parks; thus causing issues with the human population. Most people living in Illinois have hit or nearly killed a deer driving on Southern Illinois roadways. This common occurrence could be kept at bay or maybe even avoided if the deer and wild game had more space to reside. There are many points that coincide with this reality but the main issues are the small subtle ones that affect everyday life and are often overlooked. Picture the Illinois we will leave for our children. Do you see a lush green forest or miles and miles of concrete and steel?
The devastating chestnut blight was discovered invading its first victims in 1904. After exposure, the fungus enters into the trees cambium through the bark causing a canker. The fungus then spread around the cambium, girdling the tree, cutting of its life support and ultimately causing death. Many methods were used to try to prevent further infections, chemical fungicides, and burning other chestnuts around infected areas, but all were unsuccessful. The blight would soon reach through the Southern United States destroying all known native American chestnut trees.
P4: ‘The parks can be cruel to the animals they hold because they put a restriction the freedom they would normally have in the wild’ (para 5).
The piece I chose to do my literary analysis on was the article, The Truth About Invasive Species, written by Alan Burdick. The article states that invasive species are all around us, but the area with the most prominent amount is the suburbs of Miami. It goes into detail about how abundant invasive species are in this area. Most people who would see a strange animal in their lawn or area would be bemused, however for the people of Southern Florida, this is a recurring scene. Burdick states that “virtually everyone in the South Florida, including Hardwick, has a neighbor with a backyard menagerie of lucrative critters on hold for resale”. Burdick describes both how an invasive species is introduced into an ecosystem, and the impact the have on other species upon their arrival.
The Mountain Pine Beetle epidemic has become a major problem for North America in the last decade. While only the size of a grain of rice, the MPB has caused massive forest destruction in British Columbia as well as many parts of the United States. According to British Columbia’s government website (2012) “The B.C. Ministry of Forests, Lands and Natural Resource Operations estimates that the mountain pine beetle has now killed a cumulative total of 710 million cubic meters of timber since the current infestation began”. This damage doesn’t even include the More than 3.3 million forested acres in Colorado that have been affected by MPB since the current infestation began more than a decade ago. (Report on the Health of Colorado’s Forests). These aren’t the first outbreaks of the MBP though, and the beetle itself has been around for over 12,000 years. (D. Six n.d). There have been recorded outbreaks dating back to the 1920’s, but what makes this latest one so severe? (MBP Symp 2003) (p.43). The answer to this question is, a perfect mix of warmer winters, longer, drier summers, and larger, older pine stands.
Once the gray wolf population had declined in the National Park, many ecological impacts were observed. Without a sustainable wolf population in the park, the elk population began to take over and increase in size. Due to this increase in elk, many of the deciduous woody species began to become overgrazed. With the e...
The red imported fire ant, Solenopsis invicta, is a very invasive pest in Southern U.S.A. and in all parts of the world. Scientists determined the arrival of these ants is by the unloading of cargos at the port of Mobile, Ala i...
America’s Old Growth Forests are an endangered resource that is quickly disappearing. The ancient forests are being unnecessarily wasted, and are growing smaller and smaller with each passing moment.
As long as humans have lived in forested areas, they have cut down trees for lumber and/or to clear space for agricultural purposes. However, this practice has resulted in the destruction and near extinction of our national forests. Today, fewer than five percent of our country's original forests remain (Thirteen) and the U.S. Forest Service continues to allow more than 136,000 square miles to be logged each year (Byrant). Even more alarming, is the fact that only twenty percent of the current public forest lands are permanently protected by law, leaving nearly eighty percent to be consumed by chainsaws and bulldozers (Heritage...).
In 1996, the Asian Longhorn Beetle made its way into the New York and New Jersey creating the decimation of the forests. The Asian Longhorn Beetle has so far caused the cutting of over 10,000 trees in New Jersey, and quarantine of 109 miles in New York today . The spread of this foreign beetle has created great impacts on the environment. The Asian Longhorn Beetle is an invasive specie, a harmful specie from another locations, mainly other countries, that has ended up in a foreign habitat. As time has progressed, invasive species have continued to come into our environment more frequently creating many unforeseen consequences. The relationship of invasive species within the United States’ environment and ecosystem has been changing ever since the arrival of the Europeans in the 1700s to present day. Due to these encounters with other species whether harmful or neutral, the majority, if not all, of the United States has been affected with the threatening encroachment of native species due to the industrialization of waterways and transportation.
Not only this but at least “forty-six to about fifty-eight million square miles of forest are lost each year; this is the equivalent to 36 football fields every minute (WWF).” This is commonly known as habitat loss when the homes of animals have been destroyed due to the renovation for humans greater good. Unfortunately, people do not check the trees and remove animals before they decide to cut and rip trees out of the floor. Animals are not only killed in the process of trying to build new buildings but are also having to look for a new place to find home. The animals who managed to escape the terror of the bulldozer will find a new habitat, some may appear on some people lawns, or the third option in which they die due from inability to find a home or have become road kill. Not only is destroying trees and plants without a thorough investigation to make sure that all trees have been recorded. This is important because “scientists have cataloged less than 15 percent of plant species now alive—and current extinction rates mean many unknown plants will wink out of existence before they can be recorded (National Geographic).” Since the human population obtains all vaccinations, vitamins, and cures for disease all come from plants it is difficult to agree to have a Wal-Mart placed in this
