False Brome Invasive Activity in Oak Creek Watershed Introduction The intent of this document is to observe and characterize the activity of Brachypodium Sylvaticum (False Brome) as a noxious weed at Oak Creek watershed near Corvallis, Oregon. False Brome is a slender, drooping bladed, perennial bunch grass that is native to Europe and North Africa. It was first introduced to Oregon in the 1930’s and by some estimates, it has spread over 10,000 acres in Oregon—specifically in Western Oregon: Linn and Benton counties.…

Stump and root sprouting is a common way boxelder can reproduce. This may prove to be a problem in that even in these trees are cut they can still regenerate well. In addition, boxelder is shade tolerant meaning it can grow well with little sunlight. When being a competitor, this can hinder growth by catching up to and surpassing a shade intolerant tree and affect its growth. DeWine and Cooper’s study of boxelder used to control invasive plants showed that boxelder has the ability to out compete a species.…
So far, this helps prove our hypothesis since the non-native plant had less damage on it. Next we have the second group that contains red bay and Florida anise tree. Red bay had a pretty low number of leaves with no damage at 59 while anise had a whopping 136 leaves that had no damage. For the less than 10 percent section red bay has 89 leaves while anise has 184. For less than 30 but more than 10 percent red bay had 69 and anise had 38.…
This is significant to Botany as a science because as plants are transplanted from one place to another, they…

Bringing non native species into our area can be very detrimental to our environment. The Canadian thistle is the perfect example. The weed can affect our crops and pastures by forcing farmers to spend extra money on herbicides. Even though herbicides can take care of the weed, it negatively can affect the environment and ourselves when we consume the produce.…
Invasive species in wetlands of the Mojave Desert negatively affect all aspects of the ecosystem. Invasive species are overtaking most of the wetlands in the Mojave Desert. Wetland areas in the desert are rare and very important sites for desert wildlife and migrating birds. Some of the main species that are invading wetland areas are Salt Cedar (Tamarisk spp.), Russian Knapweed (Acroptilon repens), Pepperweed (Lepidium latifolium), Fivehook Bassia (Bassia hyssopifolia) and Cheatgrass (Bromus tectorum).…
Abundance of False Brome invasion in relation to distance from Oak Creek Apachino Villarreal Introduction Invasive species have been introduced to many ecosystems and can have detrimental effects due to their dominance and ability to spread easily. When an invasive species is introduced to a new ecosystem, it begins spreading and outcompeting the smaller species and creating a new type of vegetation that is not beneficial to the community. An introduced species can spread differently based on existing plant abundance and how the alien species can pollinate seedlings in any area.…
Invasive species are easily comparable to the explorers of the old days. Explorers could be helpful by introducing new supplies, like horses, during the big Columbian Exchange. Explorers could also be largely negative, bringing disease and slavery into the nations they conquered. Explorers sometimes just set up trade relations and left well enough alone. Much like these explorers, invasive species have the propensity to help, hurt, or assimilate into their new surroundings.…
In the United States to the southeast inhabits an alien species destroying and deadly to the environment. This invasive species is known as the kudzu plant and according to the U.S Fish and Wildlife service there are approximately 50,000 invasive species in the U.S, some causing more damage than others. Invasive species are species that come in contact with an area that they are not native too and can drive out animals. Some invasive species have even caused extinctions of native animals and plants and are a big problem to ecosystems. We need to help and solve the problem of non-native species because a lot of species are here because humans if we don't help and take action quickly things could get worse, and humans could face issues because…
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.…
Non-native invasive species have caused conservationists and ecologists to stew. In simpler terms a non-native species is a species that is an alien to an environment, but will not cause danger. Invasive species are species that causes harm. More specifically, a non-native invasive species are a particular type of species that are foreign to an environment and causes risk towards that particular environment. Non-native invasive species, invasive species and NNS will be used interchangeably.…
There are many species all over the world in many different ecosystems. But some of these species do not belong in the ecosystem they are in and these are called invasive species. Invasive species are non-native species of plants and animals introduced to an ecosystem usually by humans. The invasive species can thrive in an ecosystem where there are little to no natural predators and an abundance of resources. Due to these factors the invasive species can dominate an ecosystem and disrupt its natural balance and cause major harm to all of the other species in that ecosystem.…
What is an invasive species? According to the National Invasive Species Management Plan, an invasive species is defined as “a species that is non-native to the ecosystem under consideration and whose introduction causes or is likely to cause economic or environmental harm or harm to human health”. Invasive species will look like they belong in the environment they are taking over, however, more than likely they are over-powering a native species in their own habitat. Would you be able to identify one of the species I’m about to discuss? North America has more than twenty-nine hundred invasive species in our environment today.…
