Chestnut blight

occurred was the Chestnut blight. The American Chestnut was a malleable resource used for its widely used wood and its chestnuts which fed animals and people alike. Its importance made the discovery of a fungus called Cryphonectria parasitica, also known as Chestnut blight, so devastating (Hebard). Importing of Japanese trees brought this Chestnut blight fungus to North American chestnuts and it had infected chestnuts throughout America by the early 1900’s. The Chestnut blight had killed over 3

The American Chestnut and the Functions of Silviculture It’s incredible how many purposes silviculturists have to maintain forests. The main functions of silviculture include control, protect, facilitate and salvage. Aspects of these functions can be observed at the Lafayette Field Station among the growing American chestnut trees. Silviculturists use control to manipulate the growth of forests for certain benefits. Controlling a forest can be done by altering a tree’s genes, adjusting its sunlight

Fungal diseases can be detrimental to the health of many organisms in the ecosystem and extremely hard to control the spread. Three once commom tree species in North America have been devastatingly impacted by the spread of Dutch Elm disease, Chestnut blight, and Butternut canker. All three diseases were brought from abroad. They were spread quickly in various ways, negatively impacting the well-being of native habitats in North America. After Dutch Elm disease was introduced to North America in 1931

Endangered species can change a habitat due to their role in the environment. The EPA helps protect these endangered species with the help of National and State Parks in the United States. Each endangered species has different factors of why it is becoming endangered. Endangered species are sometimes caused by their loss of habitat. Reasons for the endangerment of a species can vary greatly from their loss of habitat to high genetic vulnerability to invasive species. Rapid climate change contributes

Figure 1. shows the average leaf mass decomposition rate for invasive species leaves and native species leaves Results Explanation – In the experiment, we found that the invasive species leaves have a isopods faster decomposition rate than the native species leaves. The treatment used in the experiment differentiated only where the 1 gram (each) of the two different types of leaves were used. At the end of the experiment, the leaves had little to no moisture left to them and the 2 isopods were

Imagery is a very vital aspect in most all poems. In “Design” and “Pied Beauty” they go through an extended amount of imagery. Both poems seem to point out unusual aspects in nature. For instance, in “Pied Beauty” Hopkins states “fresh-firecoal chestnut falls; finches’ wings” (4)1. In “Design” Frost mentions “I found a dimpled spider, fat and white, / on a white heal-all, holding up

intention of continuing the American chestnut restoration project that I initiated last semester. I was enticed by the appeal of bringing a lapsed keystone species back into the forests of Vermont, and the romantic legacy it might provide for my project. Unfortunately, I encountered a few challenging roadblocks in the American chestnut project’s early stages of implementation, such as lack of availability of blight resistant seedlings and the reality that non-blight resistant seedlings would most likely

the introduction of species we wouldn’t have to fix the damages that were left from agriculture, forestry, and other human enterprises. For example, in Asia there was a chestnut blight fungus tree that was introduced in America which left a disaster for many animals, such as ten species of moths that lived on the chestnut tree’s had became extinct. If we were to restrict the introduction of species the ten moths didn’t wouldn’t be extinct in this case. The cost of fixing these environments are

Utopia is usually defined as a place of ideal perfection, an ideal world; although this concept is rather ambiguous and is widely debated in contemporary society. The notion of an ideal world originated from More’s text Utopia, in which Hythloday describes his ideal world, although More disagrees. This leads to the conceptualisation of utopias being subjective, as people are influenced by their respective texts, cultures and values when they envisage an ideal world. Ray Bradbury’s There Will Come

The Untold Cost of Invasive Species Jessicarose Thurber Environmental Economics EVSP201 Professor Ray Bartholomew March 30, 2013 Imagine going on a day hike through your favorite forest. You take great pains to pack your gear, ensure you have adequate food and water for the day. You bring your camera and other gear to ensure you get photographs of the local forest. You visit this same place every few weeks, it is close to where you live and the scenery is amazing. There are ample opportunities
