The mountain pine beetle epidemic is causing environmental and social impacts to much of British Columbia. Our forests are very important and will no longer be able to maintain their role if changes are not made. The devastation has had a sweeping impact on B.C.’s ecological, and economical well-being. Additionally, recent studies are drawing attention to the carbon-emitting properties of the dead forests, which is a global concern. A popular misconception developed that the current provincial mountain pine beetle epidemic began in Tweedsmuir Provincial Park.
The valley and surrounding hillsides included different species such as black walnut hardwoods, red and silver maple, beech, red and white oaks, sycamores, white ash, yellow poplar, black and pin cherries, and some softer wooded aspen, sweet birch, and American basswood (a.k.a. linden). 4) If the area around the valley had had more rain before the fire, what would have been the effect of a lightning strike on the surrounding trees? And why was the pitch pine so critical to the story? What might have happened if the lightning had struck a healthy oak instead?
Indiana Bat The Indiana Bat has been on the endangered species list for New Jersey for over 40 years. This bat species lives in various states of the Eastern US. They are small bats that hibernate in caves and abandoned mines in large numbers. According to US Fish and Wildlife Service, a fungal disease called White Nose Syndrome is one reason that these bats are on the New Jersey endangered species list. When they are not hibernating, they make shelter among trees and their habitat is destroyed when forests are cleared thus leading to their
Cinnamon Fungus Violet Westringia LERDERDERG STATE PARK FLORA The Lerderderg State Park have over 350 species of flora are found at the park. 28 of those 350 are listed as rare or threatened species. 17 plant species are listed as pests of the park. The majority of these are confined to the more damper environment of the gorge and park boundaries. Weeds are also very common within the park.
Bush Honeysuckles Bush Honeysuckles are inavasive species plants that grow quickly and agressivly diplacing other Plants. Bush Honeysuckles are harmful to plants, mammals, and wildlife. Of the roughly 2,300 inavasive plant species in Indiana, 25% are non native and are responsible for degrading and destroying thousands of acres of our natural plant communities of Indiana. Bush Honeysuckles where introduced to Northern America in late 1800s and 1900s. They are now reported to be found in 81 counties in Indiana.
Marissa Ojeda Mr. P. Falk Honors Biology Period 1 22 September 2011 Invasive Species Paper In 1935, three thousand cane toads were released in sugar plantations in the northern part of Queensland, Australia. The cane toads were released to control the beetle population that was damaging the sugar cane crops. “Unfortunately, the Cane Toad did not control the insects and went on to become one of Australia’s most highly invasive species, currently occupying over 500,000km² of Australian mainland, with densities reaching up to 2,000 toads per hectare when Cane Toads first colonize a new area”¬(Exotic Animals 1). The government is trying to eradicate the cane toads, which are considered pests, by asking all who find them to collect them and dispose of them. The cane toads should be eradicated because of its negative impacts towards the ecosystem and the food web.
This study is about the European buckthorn (Rhamnus cathartica, L.), which is an invasive shrub to the woodlands of northeastern Illinois. The European buckthorn is detrimental to the environment because the shrub alters the soil properties where it resides, which forces the natural plant inhabitants of northeastern Illinois to adapt to the sudden change in soil properties. Due to the changes in soil properties, many of the natural plant inhabitants die from the high amounts of nitrogen and carbon the European buckthorn puts into the soil. This study was done mainly outside the lab in the woodlands of northeastern Illinois at three different sites, the Lake Avenue Woods, the East Woods in Morton Arboretum, and the Mary Mix McDonald Woods. The
Trevor Mr. H HIS 155 10 October 2014 Effects of The Black Death-Analysis Paper The Black Death was a pandemic disaster that affected all aspects of life in the Middle Ages of Europe. Depopulation and shortage of labor hastened changes already inherent in the rural economy; the substitution of wages for labor services was accelerated, and social stratification became less rigid. Psychological morbidity affected the arts; in religion, the lack of educated personnel among the clergy gravely reduced the intellectual vigor of the church. After a brief respite, the plague resumed and touched almost the entire known world. The plague caused significant changes in the civilization of Europe and other surrounding communities.
The forest is filled with wild habitat such as reptiles, animals, insects and trees. Most trees in a temperate forest are deciduous, which means the tree loses its leaves their leaves in the winter. Examples of deciduous trees in temperate forest are maple, hickory, oak, or beech. White-Tailed Deer is the largest plant-eating animals in the forest and largest mammal is a temperate forest is the Black Bear. According to Marietta College Department of Biology and Environmental Science (n.d.), “the biggest threat to the forest population is development and agriculture.”
At the local level, the introduction of specific pathogens or pests from one continent to another has led to dramatic reductions or losses of species in forest ecosystems. For example, alien European and Asian organisms have led successively to the decline of six dominant forest species or groups of species in the eastern USA - first oaks (caused by gypsy moth), then five-needle pines (by a blister rust), then the American chestnut (first by Phytophthora and then by chestnut blight), then firs (by the Balsam wooly adelgid), then hemlocks (by the Hemlock wooly adelgid) and the American elm (by Dutch elm disease). All of these declines have led to marked changes in forest composition and their consequent ability to deliver forest services. At the ecosystem level, there are a number of ways in which invasive alien species affect ecosystem stability and function. These include creating unstable ecosystems (where "invasive-species monocultures" are highly susceptible to population collapses); establishing
