Thomas Hairston, Laura Drake, Will Young, Joanna Sanford, Skyler de Regt, Boyd Anderson PSS 3133 Introduction Ailanthus altissma or more commonly known as the Tree of Heaven was introduced to the United States as an ornamental. The Tree of Heaven originated in Northeastern and Central China and Taiwan. It was introduced to the U.S. in 1748 by a Pennsylvania gardener. The Tree of Heaven is a deciduous tree that can reach 80 ft. and 6 ft. in diameter. It has smooth pale gray bark with…

Invasive Species: The Raccoon The Raccoons are omnivorous(Plants and Animals) predatory mammals that can weight over 10 kilograms.(Reference 6) They are known for their intelligence, even a 4 year old raccoon has been able to dance clap and sweep the floor.(Reference 5) For my invasive species I chose the Raccoon (Sometimes spelled Racoon), it’s originally from North America and it escaped to Germany in 1934 and 1945. The Raccoon was introduced into Germany 2 times, in 1934 when a poultry…

What do you think an invasive species is? Well, invasive species are any living organism that causes harm to humans, the economy or the ecosystem. These species have similar traits which help to identify them, they have a : fast growth rate rapid reproduction high dispersal ability Invasive species are capable of causing more harm then you realise, they can completely wipe out native plants and animals to that area, forcing them to extinction. Invasive species can reduce biodiversity, they…

an Australian tree commonly known as black wattle. Like many Australian acacias, it has been introduced to other parts of the world. In South Africa, it listed as Declared Invasive (South African Department of Environmental Affairs, 2016), along with several other species of acacia, due to negative impacts on native flora (Henderson, 1989). This negative impart comes largely the ability of acacia species to germination prolifically and rapidly under conditions of extreme heat (such as fire)…

Invasive species in Idaho is a problem. Being mostly plants on the top 10 list of Invasive species in Idaho, the feral hog is slowly making it’s way to the south and west boarder of Idaho. First being introduced in the 1500’s by Spanish explorers, in Tampa Bay, Florida, the feral hogs has slowly choked the wildlife of the southern statesand beyond, but they have also shown signs of huge population growth in 45 of 50 states in America. In Texas the war between human and hog has resulted in a lost…

Invasive plant species pose a tremendous threat to natural resources throughout the United States. Invasive species can choke out acres of native vegetation and greatly reduce wildlife habitat. Invasive plant species threaten every aspect of ecosystem health and productivity on public and private lands, threaten biological diversity by causing population declines of native species, and alter key ecosystem processes like hydrology, nitrogen fixation, and fire regimes. Preventing, managing, and…

Introduction Mediterranean (House) Gecko The Mediterranean gecko (Hemidactylus turcicus) is a small gecko common to the Mediterranean which has spread to many parts of the world. This lizard is native to the Mediterranean and west Asia. These species inhabit in parts of Taiwan, Polynesia, Somalia, Madagaskar, Andaman and Nicobar Island, Bangladesh, Nepal and Bhutan. In fact they are now also found in Australia, Mexico, Brazil and USA. It is also commonly referred to as the Turkish Gecko as…

The Impact Assessment Committee for Introduced Species has been asked to produce a report for the Australian Government which assesses the effect of the introduced feral cat on the biodiversity of the local Mackay region. The assessment will result in the formulation of two proposals which aim to address the threat to the ecosystem, and appropriate recommendations will be made. Primary sources of information surrounding the feral cat situation was utilised throughout the making of this report,…

in overgrowth of forested areas with native and non-native species. This would also provide environmental conditions that would require plants to adapt and change their native characteristics. This could in turn affect the ecology of the region as old ties in the ecosystem are broken and new ones are formed. In the example of the non-native toadflax given previously, the poisonous nature of the plant allows it to out-compete native species that serve as food for local fauna. In time, the…

These outrageous and unexpected invasive species. they are the monster goldfish and the wild boar of how these innocent creatures became such monsters. The goldfish can be invasive species. From source 1: The Monster goldfish is a normal goldfish that got dumped by the owner but then grew and grew and grew until it was huge! they, of course are much larger than normal pet goldfish. It invaded a river in Australia and a lake in Colorado. These oversized goldfish have turned blue water into brown…
